Back to topic.. the Holset HX35 is perfect for the KA, CA

[WDRacing]

I have no issues with the guys over at the Org, hell most of them started right here on Nico. I simply won't tolerate guys coming around and not offering anything but attitude and negativity.

Nico is a family, if you are the ugly step child then you don't get invited to dinner.

If anyone ever has a problem with how I handle things you can alway email me. [email protected]

im open to his input..... but not once did i ever say i wanted over 350hp... hence my reason for my attitude toward him. my goal was 300, maybe 350hp at best for right now. i know what i need for what hp. ive read the stickies and if you look i have been on this forum for a long time just reading.

but thanks guys, for all the help haha.

Hey WD, I got KATW0's old T3/T4OE!

[WDRacing]

Sweeeeet...I haven't talked to John is weeks. I miss him

Sorry to ask again but with what happend no one answer my question!

For a 250-300whp setup i guess the HX35 is just to big(useless lag) so would the HY35 be more appriopriate? What about lag on it? And is it T3 flanged or it needs some custom work on that part.

P.S. Are rebuild kit from ebay goods, or they are like most turbos on their (Chinese crap)?

[Reno]

i prefer the lag just to save gas! DD FTW

[boznuttz]

I don't think he's been on the site for a while. Last I heard he had LSx dreams.

No big deal, he hooked me up fo real!

I dont think that the hx35 would be too big. The hy is the smaller of the two. Either turbo would be sufficent for your power goals. If you are worried about lag go with the hy35. Most seem to be full boost (7-10psi) around 3100-3200rpm.

[Gisqc1]

Ok that's exactly what i wanted to hear... but one thing bother me... will running low boost (10psi) on a HY makes it surge or something? And i guess it won't die off until i hit rev limiter? (Hopes there!)

Of course if both get the job done well... i'm going to choose the fastest spool up...

Btw i'm curious got any idea where the HX should hit 10psi at ?

[GTR PrYdE]

Is HY35 the full name of the turbo(for searching purposes)?And is there any good places to find them at?

[Skeeg]

most people i see get them off EBAY... yes the model name of the turbo is HY35... its an older version of the HX35, but i think the hy is from 2000-2002 cummins trucks if i remember correctly, if not im sure someone can say.

another place to look would be a dodge turbo forum, as most of them just toss these away wen upgrading b/c they are pretty small for their engines so they dont go for much.

[Gisqc1]

actualy the HY35W (pretty sure they are most wastegated) is on automatics 01-03 cummins (maybe 00-03 i cant remember) and anything past 04 are HY35W too.

Ebay, diesel forum, if u want some new stuff turbo diesel shop ...

Still wondering about the spool of an HX35 (10psi) on a ka24de...

[boker240]

i think the w just stands for wastegated . they come off of the 6 cylinders 5.0-6.0 trucks and if im correct a new one is fairly exspencive,like 1200$ not for sure though.and even as low as 10 psi i hear they hit like a freight train. i got one but its not on yet. got it for $340 shipped w/ 33,000 miles from dude on ebay.i did get it w/ the wastegate on it , i blew 20 psi of air into the wastegate port ,,,,,,,it did not open,,so i did 25 and it started to open so i did 30 and it opened most of the way. idk if this meens its set at 30 but i know those trucks run high psi so prolly was. i blocked it off and gonna use external gate @ 11.5 psi.

[WDRacing]

Yep, most trucks run +30 lbs of boost. One of our mods has a Dodge dually that runs at 80psi with two huge turbo's. He ran it in the 1/4 last year at Nopi Phoenix. Ran 13's IIRC...truck weighs like 8 bazillion lbs

When he had 4WD off on the first run, he smoked the tires the entire 1320 feet.

[Gisqc1]

Yes the W stand for wastegated i just wasn't sure if they were all wastegated or no so my hesitation was more at the name of the turbo...

However, from reading honda tech 80ish page topic (damn it's long) at first i thought that a Hy35 was around .45-48ish a/r and the HX35 (12cm housing) was around .63ish a/r, until someone reputable posted some new numbers

From TTT (TheTurboTrader) it's at page 59 btw

FYI=

6 cm2 = 0.41 A/R7 cm2 = 0.49 A/R8 cm2 = 0.57 A/R9 cm2 = 0.65 A/R10 cm2 = 0.73 A/R11 cm2 = 0.81 A/R12 cm2 = 0.89 A/R

i guess im going to stick with an HY35 knowing these... i'm pretty sure .89 a/r is to much for boost/power goal i want.

Also i hope these infos can help people out there with there holset turbos!!

As for the wastegate there's no way i'm going to run the stock on... external for the win for low hp's! Btw, i'm curious does anyone got a pic of there internal wastegate welded so it doesnt pop off?

Thanks

[boker240]

yea, i ran a ford excursion in the 1/8 th ,,,he ran a 8.2 at 80 somn mph and murdered me off the line ,i was like

gisqc1 thanks for that info ,its good to know , i also down loaded the hy,hx35w,fsm from somwhere cant remember though , i look and try to hook yall up wit it if u want , lots of useful info .and i bracketed mine shut w/ a peice of metal that i bolted to the rod and bolted it to one of the bolt holes that the factory wastegate used.

[Gisqc1]

Also, i was wondering how the "stock elbow" on the HY35 would work ? It seems pretty tight...



Beside air flow, that will propably be a plus when it will be time to run Ic piping

[BoostFab]

the elbow is fine, just better when running the intercooler piping, eliminate an extra bend you will need. i think clocking it downward is better.

[Biggamehit]

I have been running my H1C for a bit now.. i just had to build my own manifold and modify the outlet by welding a vband flange on to mate it to my down pipe.

not to little at all and not to large.. this turbo is perfect for what i want.. when im drifting with it i can stay in the power band.. drop it if needed and im right back in it... fully spooled at appox. 3200 rpms

as far as where to get them look no further than http://www.goldfarb-associates.com/

i had the pleasure of going to his shop and hand picking my H1C from hundreds... good stuff and he sells a ton on ebay

[Gisqc1]

damn what boost are you up to at 3200rpms? also what ur exhaust size ? 12cm? divided?

Now i'm wondering if the 9cm housing on the HY will spool to fast compare to this... probably high 2000's.

Well on honda tech ive read a guy that was able to keep the boost up trough all his powerband (under 4k spool up to 7.5k i think maybe more) and he said the turbo still had potential...

[boker240]

just thought this would b helpful to holset users.

http://www.holset.co.uk/ - 10k

if u allready have it then cool.

[Gisqc1]

Also... if you look at the HY35 it doesnt have a flange on anything to bolt a downpipe to its a clamp... but can you just clamp a downpipe to a turbo?

I was think at welding a custom flange on that end and get a matching one to weld on my downpipe, how does that sound?

[GTR PrYdE]

That is such a giant exhaust housing... how does it spool at 3200?!

[boker240]

my hx has a 2.5 inch v band on it stck, so just welded a 3 inch v band clamp from atp turbo to it.

[Biggamehit]

Gisq... from the looks that is an 4inch vband outlet... all you have to do is get a 4in vband kit bro..... that clamp may or may not clamp from the holset's lip to the vband flange with the kit.... that was my issue and i just mated the flange to my turbo using a combo of mig and tig welding.

about the boost:

in simple terms because its and diesel turbo with a bunch of science behind it... but check out the compressor housing, it is smaller and the exhaust housing is bigger and doesn't chock the motor out at all. the compressor housing looks small but the wheel is pretty large.... honestly with holset's you can get compressor maps etc, but these turbo's are made with the lower reeving diesel motor in mind not Gasoline.. but they just happen to work so well.

remember they also have hx30's also.... and dude no hx/hy35 will be spooled at 2000rpms unless you spaying lol even still........

my turbo is similar to a Gt30r/35 ( sorta) In reverse for

more better pics and some info on my Turbo

TURBOCHARGER MANUFACTURER: HOLSET #765TURBOCHARGER PART # 3522900TURBOCHARGER MODEL # H1COIL COOLEDWEIGHT: 19EXHAUST WHEEL DIAMETER - 60mm.COMPRESSOR WHEEL DIAMETER - 45mm.

I did the math for the trim and came up with 56 but that was just with the numbers given, i really want to measure the size of the inducer and exducer and get the proper number for both sides.

the angle of my photo makes the exhaust housing look very very big these will put it in perspective.

** when i bought my manifold kit i didn't get the twin scroll T3 flange so when I get back from Iraq ill be cutting the regular t3 flange off and putting the twin scroll on to take advantage of that technology.**







issue with vband 3 inch outlet with 2.5in indentation, clamp would not fit



solution

[Gisqc1]

well i thought of that cause making my own flange and then weld it on the turbo and to the same for my downpipe would save money and wouldnt be really hard...

Btw does that mean it going to start as a 4 inch downpipe than ill need to reduce to 3 inch?

And btw with a Z32 maf can you run the 4inch intlet or you need to reduce to 3inch to plug in the maf?

For the spool i was more wondering i meant about 2800-2900 rpms who knows... i still think 3200-3300 is more possible thought..

[Biggamehit]

well you will have to make custom dump/downpipe no matter what.. i did mine inside of 45 min easy stuff man... measure size cut weld

as far as z32 maf that has nothing to do with size of inlet... that has to do with your desired boost level and hp goals........ i am running a n60 maf and they are good into the 3xx range.

oh and yes sir.... if that is indeed 4in, you will have to downsize to an 3 inch setup..... the issue there is space... you would have to mount the turbo as close to the dizzy as possible
