Hello
as many of you have come to know, i don't exactly follow the "traditional" methods of modifying a car. I use whats available to me and don't mind getting my hands dirty creating my own parts etc. The reason that I bring you this info is to explain my finding and more importantly my hands on experience with Holset turbo's. i will try to be as brief as possible because the links will provide more pictures and info for you to read and understand.
These turbos simply are great alternatives to the more popular Garrett, Turbonetic's, etc turbo's. what a lot of people don't take into account is, the holset's are made for much much bigger diesel engines. as you will see the HX series turbo has a wide range of turbo's that are matched to the diesel motor in relation to their displacement.
you may ask yourself.. hmmmm a hx30 is made for a 5.0 liter diesel engine and my car only has an 4g63, Sr20, Ca18, B16, B18, Vg30, Rb20 etc etc... you cant really go off of the size of the engine but you also have to use common knowledge. you cant take a Hx40 and put it on a D16 and expect it to spool fully at 2000 rpms lol. Also take into account your application: auto-x, drag, road racing, drifting etc.. they all have different requirements of your car in relation to suspension, wheel and tire choice etc....... whole different world.
ill just quote from Engine Tips.com they said it better than i could. and then ill get on with the write up.

"Just a quickie---We work, on a daily basis, w/ diesels that average 60-70+HP per liter at rated outputs. Turbo charging and low temp aftercooling has played an enormous part in allowing these types of outputs to become realistic and reliable.. As for "low-end" power/torque, again the turbo has been the one of the biggest contributors as to having a power curve with this low end power--With engines rated at 1800 to 3000 RPM max ( 25-30+++ PSI at WOT) , we see boost starting to rise rapidly from 1000 rpm and up with 15-20+ PSI in the 1500-1700 RPM ranges on many engines.. Newer waste gate technology, new or variable shaped air turbo inlets, and new ideas in turbo air mapping has allowed new designs to give this low-end boost while controlling max boost pressures at high speeds--- In a nutshell, turbos do not just engage or "turn on"--They come up to speed based on design and the power that the engine needs to deliver whether that is at a low RPM below peak torque, in mid-RPM's at peak torque, or at WOT..
"A diesel engine pumps 100% of it's air capacity 100% of the time while a gasser pumps 100% of its capacity only at wide open throttle. Reason out your question based on that tip. rmw " |
Initial Info/facts
--------------------------
these site were helpful to me when i really got into holset's/turbo systems some years back
quick chart i made so you don't have to link up to the site if you don't want to
Boost levels for respective dodge ram truck years..... use this to somewhat assist you...but note. psi levels are met much faster with diesel motors. You can use the stock wastegate, but i just would not do it on the bigger holset's.. the chances of spiking is much higher. the W in the turbo name stands for "Wastegate"
these turbos are cheap for us because they are for a truck application.... and not really built for after market performance in mind. 4-6 cly Mustang guys have been running holset's for many years now
these turbos are awesome quality... one night while going home after welding up my exhaust..... i noticed my oil pressure was acting up.... so i pull over and wow ..... big hole in my oil pan from a puncture. i was driving at a very high rate of speed... lets just say my turbo spooled for little over a mile with no oil at all... I took it apart and everything was fine.
for smaller applications
the hx30 goes unnoticed and the hx25 is another good one...
here is a picture of the hx25... will bolt right up with T2 flanged manifold
Where to get them?
---------------------------
i found a H1C on eBay that i was looking for when i built my turbo kit some years back. To my luck not only did i find it, but the shop was located in Rockville MD. I talked with the owner of the company and he allowed me to come check it out before buying. The turbo was as described, " zero shaft play no leaks etc". He also allowed me to browse through his shop freely and was very excited to show me his latest turbos that had Zero miles on them etc.
This shop houses EVERY holset ever made (H1C,H1E,H2C,H2D,H2E,HX30,HX35,HX40,HX50,HX55,HX60,WHX80,HX82...........
SOURCE) and many OEM Garrett chargers. some are rebuilds/parts only. some are in fair to new shape. many of the BIG ones power Detroit trucks, Earth Movers, Marine equipment etc.
they are great project turbos for DIY guys/gals and cost way less then the leading brands and are the same quality and better in some aspects. many of them that you see in the pictures that can actually fit in our cars without major modification are mainly T2,T3 and T4 flanged with either 4/5 bolt and v-band exhaust outlets. for the most part you can use standard feed and return oil flanges. some are threaded for use with banjo bolts. It takes minor modification ( drilling, tapping, converters etc) to make them work
GoldFarbinc ebay store

Whats needed to Install the Turbo?
-----------------------------------------------
As with all turbo setup's a few things will be the same universal and those things are:
Turbo
exhaust manifold
oil lines
fittings
Intercooler and pipping
Wastegate ( internal or external )
I initially thought that getting this revhard manifold would free up the space i needed, but for my application, the turbo was to close to the master cylinder. I had to create my own manifold. Some of you guys will luck up and have a manifold design that allows you to run the holset of your choice with little or no modification
in this picture i still have three other important parts that led to an quick fabrications of parts for my turbo set which are the turbo, v-band kit and the 180deg mandrel bend for my downpipe.
however you must make sure you have the correct flange type.. common holset flange types are T2, T3 and T4 just like the popular Garrett etc turbos
this is the manifold kit that i got. the reason it worked so good for me was, i was able to mount the turbo where i wanted. there is nothing at all wrong with pre-made manifolds. but when you get into modification, nothing goes as planned, so it would have sucked to spend more money on another manifolds and not get the fitments i needed. there are Log manifolds available that could have fit my H1C, but they were like 400 dollars+ and i had the means to make my own.
where turbo is placed ( ill see if i can find a picture of the finished product)
Oil inlet and outlet
this is what holset's commonly look like in this department.. as you can see, the outlet has standard 12mm bolt threads and you can mate the T3 oil outlet flange to it. the inlet however has a Banjo style fitting.... you could fit a T3 inlet flange on there, but you would have to drill and tap it
Fittings
all you have to do is get a 12mmX1.5 to 1/8thnpt reducer fitting. these are commonly found in plumbing stores, you can get it at home depot and it will not break. or you can get a fitting from auto stores that go from 12mmX1.5 to -3an or -4an
looks like this somewhat with smaller inlet of course.
look at the oil feed location of my turbo you will see it installed with the 1/8thnpt fitting screwed into it
Oil lines
standard -3an or -4an feed and -10an return which you can get from summit or eBay pre-made, or you can make them yourself like i did... i also have a oil jet kit that allows me to adjust oil pressure.
Turbo exhaust modification
with the holset's you will find out that they are v-band style for the most part, it will vary. this is the way i had to attack my setup.
my v-band idea didn't work as planed because my turbo has an 3in outlet and a 2.5in indentation that made it impossible to clamp and join my downpipe.........sooo........ i had to weld the flange onto the turbo like so. the pictures will explain the rest.
dump/Downpipe
Now we all know when you work on cars for a long time.. sometimes things will fall into place, but that only happens when mars aligns with the earth and all that jazz.
more than likely you will have to create your own dump/downpipe and or tweak what you have. this is what i did with the help of a buddy and a cool *** tig welder. i didn't make a divorced downpipe, its all one piece
(the oil is gone.... had a nasty oil leak) Had to bang on frame rail a bit to clear space for the exhaust
Final Product
NOTE:
time to gather parts 2 weeks
downtime: 2-3 hours
If you have question about anything ill try my best to answer it..
later
Carry on

yea there are maps available but i didn't want to add them..
for compressor maps just Google it key word
Holset HXxx+compressor maps
yea the h1c was picked because after viewing maps i knew it would work good with my motor. and its awesome power in all ranges. also the way i built my manifold compliments it. however im starting to wonder how much better or worst it would respond if i had added the twin scroll flange..

| While a diesel turbo can work perfectly fine on a gas motor, the same rules apply. That is, it should be matched to the motor to provide good efficiency where it is needed. I would have to see compressor maps of these turbos, but I would question how well these turbos might match up against a KA, particularly in low to moderate boost levels. The Ram Diesel specs indicate that it makes the power a KA might at as low as 7 psi while reaching boost levels of up to 20+ psi. In other words, these turbos may have their peak efficiency islands at low airflow rates for a given pressure ratio. Which makes sense as truck motors typically make better use of having lots of torque at low-rpm's, providing relatively low HP-to-displacement numbers. I'm no expert on diesels, but I'd imagine there is some difference in energy output compared to gasoline as well, which could require much different air/fuel ratios between the two. Of course if Direct Injection Gasoline engines are any indication, diesels may be able to run quite lean as well. It's probably quite a complicated comparison. And I'm not saying a turbo that is primarily used for diesel motors can't be used in a gas motor, it's still important to map out the motor on the turbo's compressor map to get a good grasp on how well it might work. |
I am in the 77% island from 7psi up to 25psi. After about 30psi you hit the surge line. You are defintally correct. For my turbo i cant get into the 78% island becase the motor just doesnt flow enough cfm. Just do a little research and you can get a great turbo. If i switch turbo's i am thinking a HX40 or HX52 for power or a HY35 if i want quick boost. The HX turbos are more efficent so you can reach a higher island with the same cfm as a H series.

One of my buddies here in indy had a hx35 setup on his gsr hatch but he is now switching to a HX52 and switching from gas to E85. That thing is going to be a beast. I figure is the 1.8 can spool it then a 2.4 can. He will probably have to switch the exhaust housing to a smaller cm one off a hx40 or hx35.

It varies from the different versions of the hx35. Some of the hx35 turbos have a 9cm or 12cm housing while the h1e i have has a 14cm or 18cm housing ( i cant remember which). A lot of the housings are interchange able. If i want a smaller housing i can get a 12cm housing from a h1c turbo. The holsets are big in the turbo mustang and turbo bmw forums.

Thats a lot of HP for 12 psi, im not really believing that.
On most setups you dont cross 300 hp with 12 psi, even with a big turbo. The holset is no magic +70 hp turbo.
What kind of supporting mods do you have to support your claim? I see a stock intake manifold..

i'm pretty sure efeezi got 400 or 450hp on a h1c at either 14or 16psi i cant remeber and not hunting for the thread and yes he had a dyno to back it up, but thats been atleast 1.5-2 yrs ago. |
Noway, unless it was a motor run on a dyno by itself. The turbo does matter as far as size is concerned. But the Holset compressor isn't going to magically make more power then the garret compressor. The exhaust housing is a tad different, the internals are a tad different, but that's it. If Holset could make more power, EVERYONE would use it.
The average for a decent tune and well matched turbo is 10whp per psi of boost.

Went to the dyno today and found the limit of the H1C. 15psi hit 392, cranked it up to 25psi and only made 411 but had a ****load more torque. Torque started early and carried pretty far, it almost feels V8'ish. This is also with a 50/50 mix of E85 and 91 piss. |
A little e85 / gas mixed must of helped. I didnt say it couldn't be done....i said i wanted proof.

Admittedly though, if that is only on 15 psi, then 392 is a boat load of power.

i heard from a reputable source that per lb. of boost increases hp's by 7% of what ur motor is n/a. so that would meen that the ka per lb. of boost would b around 10-11 hp's.
check this out.
How it works:
In order to understand how this calculator works, it is helpful to understand the basics of supercharger technology and why superchargers make more power (check out our tech section for more on info). A rough starting estimate to calculate HP gain is to take boost (say 5psi) and multiply it by 7% (a constant) to get your approximate power gain (in our example 35%). Why 7%? Because 7% is approximately how much more air and fuel gets into the motor with each pound of boost that is added. To get a more exact figure, take 1psi boost and divide by normal atmospheric pressure, 14.7psi at sea level. 1 divided by 14.7 equals 6.802%. Under ideal conditions, you can expect to burn 6.802% more fuel and air per pound of boost. This is the starting point for this calculator, however, as boost rises above 5psi, other inefficiencies kick in, so gains above 5psi become progessively less effective in making more power. When you need to retard your ignition timing, which is often necessary when running a supercharged engine to avoid detonation, other timing inefficiencies kick in. This is factored into the "HP Loss due to timing adjustment", which is an estimate as to the amount of ignition retard that will be required at a given level of boost. To offset these losses, you can run a higher octane fuel or an intercooler, both of which increase your detonation threshhold and allow you to run more boost without experiencing detonation. For more on detonation, check out "Detonation, Knock, and Pre-Ignition 101".

Yeah that was my car with the H1C. There were no abnormal timing changes at that time. The car just flat out made efficient power with that turbo. I believe I had stg 2 BC cams and custom intake at the time. And I was running a 50/50 E85/ 91 piss mix. The 392whp was on a 1 bar spring only, the boost controller wasnt even hooked up for that run.

they are not direct bolt up turbos. you will have to make your own dump.... if you don't have a welder.. you can still get some mandrel bends once you have the turbo mounted and mock up a dump/down pipe... mark it tape it and take it to a local shop and have it welded.

I need to get the turbine off to weld the wastegate shut and i need to clock it anyways. I am having trouble getting the two to come apart. I let it sit in penatrating oil for a few hours and then attempted to seperate them with a chisel and hammer. Don't worry...i was barely tapping it. It didnt move at all. Tomorrow i plan on hitting it with the air hammer (lightly) unless anyone has a better idea.
p.s.
Its not my turbo so believe me when i say i am being gentel (spelling?)

mine was rusted together. i tried a lot of stuff, most of which are probably very wrong. what eventually worked for me was that i held the turbo by the comp. housing about an inch or 2 off of my work bench. then i wrapped the end of a hammer in a towel and hit the turbine housing with the hammer. it wasn't the "right" way or the best way to do it, but it was the only way i could get it off.

| Anyone here running a Holset HX40 on a KA? I know it will be laggy, just curious as to how much. I know it flows 70lbs/min, and that is quite a lot. Any info regarding the HX40 will be greatly appreciated. Looking to run it at 1 bar till I get pistons and rods. Thanks a lot. |
The twins car had a hx40 on it. They held the stock block hp record for a while till cory took it. They were on 30psi and made a little over 520whp i believe. Search for it and you might find their video.
As far as a hx52 goes.....they are huge. A local honda guy had one on his built gsr and he hit boost around 6K. When boost hit....you better be holding on to something.

Add heat and use big channel lock pliers n twist ever so gently should come apart.. air hammer makes me cringe.

| Biggamehit why H1C over HX35?? |
this particular H1C has a bigger compressor. i have no need for the hx35. i got good results on my kA from the older smaller H1C also it was free lol. its bigger and better than the t28 on my current rb25

what are the specs and would you ever consider a twin-scroll Mani?

I am going to break it down and do the math to figure out the Trim and A/R
this partiuclar turbine is not twin scroll. However the H1C on my 240 is twin scroll.

you only want to run a 44mm if you are seeking mega boost. there has been talks of the 44mm being good for guys such as myself who didn't exceed 15psi to prevent boost creep. I never had an issue with that with my 38mm.
whatever you do... you don't want to use the Wastegate that comes with your holset if you aquire a WHx35 etc etc etc

Yeah I scrapped the stock turbine housing due to internal cracks in the housing. and picked up a non gated housing, so the highest you took your boost was 15psi and didn't run into any problems? I was planning on taking it to 20psi at max just curious to know if anyone has experience boost creep around 20psi on a 38mm wg.

* 95 KA modified intake manifold
* 93 OBD1 electronics

* 3" V-band Custom heat wrapped Downpipe
* dsm Bov
* deatchwork 480cc injectors
* 38mm Tail Wastegate
* ssac fmic
* N60 MAF
* Hallman MBC
* Walbro 255 pump
* NGK copper plugs (gapped to .033)
* Timing backed off 3 Degress
* Emissions Deleted
* No A/C
* No Power Steering
Electronics
* Apex'i SafcI
* Apex'i Rev/Speed Meter
* Greddy Full Auto Timer
* Bee-R Power Builder Rev Limiter
* Aem Uego wideband
* Faze water temp gauge
* Faze oil pressure gauge
* Faze boost/vac gauge
drove in many events and did well in all of them boosted for over 2 years now.. this setup is only about half a year or so old and was doing very well....

All of you KA guys with H1C's or HX40's should consider this housing over the huge 18cm2 and 21cm2 http://www.theturbotrader.com/...22_25

How much boost do you think I'll need from my HX35 to max out my tune at 450-475whp? I have 86.5/8.5-1 pistons with tomie 260 procams. There is a SR with stock cams making 350whp on a 1bar spring with the HX35 on the SR20RWD forum.
What do you rev limit the KA at? If I build another S13 it will be a KA-T. IMO, the SR is a great motor for 400whp in the S-chassis WITH STOCK INTERNALS, but if your going to build the bottom end and go for big power you might as well stick with the 2.4L. The head flows better and it spools a GT35 as fast as the SR spools a GT28.

<25psi
Its all in the tune though. If the tune was for a t28 (example) you would have to pull more timing than if you ran a T3/T4, so you would be missing out on some power. Even if the tune is for a smaller T2 turbo i dont think you will need more than 25psi. A local sr guy made 377whp on a Gt2871RS @ 22psi (turbo maxed) so with a bigger turbo i think around that boost level you will reach your goal.

1. The 9cm2 housing will not flow near enough air to max out the hy35 compressor much less the HE351. The larger compressor with the small ex housing is good for diesels with slow moving cold exhaust gases trying to make power and pass emissions at the same time. The 9cm2 housing is limited to about 450whp on gas engines at 25psi and it is strapped to a compressor that will make 650whp on the HE351.
2. They have a odd sized almost 4" vband outlet that would take some serious custom work to ever get a downpipe to fit up on a S-chassis.
Bad thing is it would be a nice turbo for gas 4 bangers if you could get an aftermarket ex housing but you can't. They are clamp style housings not bolt up like the HX series so you can't change housings. Basically the HE351 and the HY35 are both limited to about 52lb/min of flow because of the little ex housing. I almost bought one until I talked to a R&D guy I work with from cummins and he said stick with the older HX or H1 series if you want more than 500whp of flow on a gas engine.
model whp range engines I've seen them on... LB/MIN flow
HY35 300-400whp (1.8L VW GTI made 350whp at 21psi) 52
HX35 350-550whp (SR20 360whp at 14psi/4G63 468whp at 28psi) 60(7blade)
HX40 450-650whp (several 500+whp 4g63's at 28+psi) 70
HX52 600-800whp (never seen a dyno but compares to GT4094 or GT42) ?(80+)

any idea how would an hx52 would spool with a twinscroll mani? KA? someone do the math plx, hmmm i havent seen an hx52 map in a while.. | Quote, originally posted by dsm-onster » |
| If you can't throw any more money out there, why don't you try to max out the turbo you have first. Take it in steps. You'll learn more along the way. It's already a fairly large turbo. One member ran the hx52 with his 2.0L motor. It spooled to 10ish psi by 4800rpms. Divided runner manifold with a t4 flange and stock holset twin scroll turbine housing (17cm^2 I think), if you interested in that route. It does not come with a t6 flange, but a flange close enough to a t4 bolt pattern that you can widen the holes of your t4 manifold to make it clamp down fine. A twinscroll turbine housing with either turbo mentioned is the way to go for a semi-"street" car. But I wouldn't even try to street a 4cylinder with either. EDIT: which gt42 are you talking about? As respects to compressors, the gt4202r flows more than the hx52, and nearly the same as the s372. The gt4294r flows less than an hx52 and s372. The hx55 flows more than those, but less than the s376. I don't know where you'd get one, though. I believe there is no gt4292r. . . |
so if i do my math correct a ka with a TS mani would spool 10 psi on a hx52 @ 4300 rpm hmmm

Big power is never my goal, a well balanced car is. I made the 204hp @ 8psi @ 5500rpms, I daily drove and raced the car, had to sacrifice some where. Im aware of all of the HX turbos, if you seek big power, they can get you there for sure. I reved to 6500 rpms and I never had issue drifting. My car seen full boost at about 3500rpms on a Log manifold
I have never ever entertained the thought of an SR. As far as my KA-T i will not be touching that for the next 4 years as I live in Japan now.

Not at all. once you go about 5mph the wheel feels normal. Besides lol I warm up with about 315lbs in the gym lol... im pretty fit lol. yes i removed the PS lines and plugged the rack.

Same exact manifold and WG I was running over on Oki...lol. I ran a big TO4 with a .81 AR hotside though. So I was REALLY laggy...and on the RB20.
I hate you for being over there

Misinformation... You want a bigger wastegate to keep boost low and prevent creep.

Higher boost pressure means more air coming in the engine and going out. You need the bigger wastegate to help prevent a boost spike or creep from the extra volume of air passing through.
Your statement isn't wrong, just not 100% correct.
