sr20det and a HOLSET HX35/HY35

[zenkiturbo270r]

hi people I haven´t been able to post the pictures yet because I am buying a new car...I had a nissan silvia s14 zenki 1995 and now I am getting a RPS13 180SX KOUKI 1997 but I am keeping the engine from the other car.Tomorrow I´ll post all the pictures of the turbo manifold.The car has full boost around 5000rpm on second gear 20psi.When I finish switching engines and tuning my haltech I´ll post a video of the car running.

[trls063]

i wanna see!

[Reno]

Bump for holset only... lol

[zenkiturbo270r]

the tittle says it 350whp397crank hp full boost at 4200 rpm(13psi get boost creep to 16) 11cm twinscroll exhaust housing custom manifold stock block worked head sr20de n/a cams haltech ecu, this turbo is amazing best 200 dollars ive ever spent in my life, ive had gt35r's gt3082r's none of my cars will ever see a garret turbo again i dont know if im the first guy with 1 of these setups but im prety sure im the happiest lol :P

heres a video of the dyno run and a short 1st and 2nd gear pull

now thats dope

[CSUPUEBLOTIM]

Dunno if would help with the manifold thing... http://jgsturbo.com/index2.html . You can get flanges and kits from them and build yourself or have them build them.

[2jztwoforty]

the holsets have been proven in the honda world for awhile now.. they flow more then a comparably sized garret t-style turbo and very similar to the gt series but for way less money. people that say that cause they where on a big truck motor have no base. diesels use very small exhaust housing due to the nature of the motors, they have quite low exhaust flow compared to a same size gas engine also lower egt's and they also dont rev high at all most redlne at 3500rpms or lower..

i've had 2 holset setups on my hondas an hx35 setup made 420whp at 19psithis setup made full boost by 4k

and then an hx52 on a built 2 liter made the same 420whp on only 8psi didn't get to play with it more on the dyno but i was running 20psi on the street had zero traction in 4th gear this turbo was a little lazy on spool up but not bad considering the size of it, 67mm inducer 100mm exducer on the compressor wheel. hit full boost by 5500-6000 but i still had a revlimit of 9500 so still had plenty of usable power

now i just got a s13 240 and i'm doing a 2jz swap in it and plan on using a either a single hx52 or dual 35/40's

[Reno]

question how would a hx52 spool on a ka24de with a twin scroll setup? by 4800 rpm?

i demand a fair answer, k thx

btw if it makes u guys feel better my dad has an sr20....

[kentuckyslider]

3 questions.......

1. lbs/min flow rate of the HX35

2. What's the difference between the HE351 and HX35W?

3. Will my 72lbs inj. and JWT rom tune and cobra MAF be enough for the HX35?(it supports 475whp on 93 octane)

[CSUPUEBLOTIM]

Why stop there? Get the HX55 and max 1000hp . We need to find an insider who can produce twin scroll manifolds of good quality at a reasonable price. Sweet dyno video by the way. Mucho Black Smoke makes it like your running a diesel lol

[Kalypso]

compressor maps would answer these questions, but im not really here right now...

im at work

[kentuckyslider]

I have been doing some research and I have the answer to a couple of my questions.....

The HE351 is off the 2004.5-2007 dodge cummins and the HX35W is off the 99-2002 24V cummins. The HE351 spools 200rpm sooner on a 2.3L ford motor and makes full boost at 3600rpm and the HX35 makes full boost at 3800rpm. The He351 is NOT twin scroll and the HX35 is. Both are on a T3 flange. You CAN use the twin scroll HX35 on a non TS mani if you choose to but get an external wastgate or it is hard to control boost. The HE351 is rated at 480whp and 55lbs/min and the HX35W is rated at 500+ whp and flows 60lbs/min. The HX35 flows about like a 60-1 and more than a GT3076 or BW S256 but not quite as much as a GT35R.

I am torn between these 2 turbos and the BW S256. The only problem is I can buy 4 holsets for the price of 1 BW or GT turbo! I am leaning towards the HE351 because it isn't TS and 55lbs/min is more than enough for my tune. I don't have enough fuel for 60lbs/min or 500+whp so I might as well go for the quicker spool up.

Here is a HE351 off a cummins test engine that has never been in a truck. http://cgi.ebay.com/ebaymotors...A1318 Cummins is based in Columbus IN, my company makes EGR coolers for the new cummins engines.

Kalypso, I have been hard after research for a Holset setup on a SR20. I will be running a holset on a treadstone mani and tial 38mm wastgate by march 1, 2009!

Here are some usefull links........

http://www.dsmtuners.com/forum....htmlh ... ?t=1225182

This site hase odd sized turbine housings for the Holset. http://www.htturbo.com/dodge.htm You can make 600whp with a HX35/40 hybrid with the larger housing.

I am sticking with my 72lbs injectors and JWT rom tune and going to max it out with a holset top mount. I am just trying to decide on what turbine housing will alow me to spool the quikest and still make 450-500whp@20-25psi. The HY35, and the newer HE351 all have 9cm2(=.48 ar) housings when the HX35 has a 12cm2(=.63ar) housing. I know I can hit my numbers with the HX35 put it won't hit full boost till around 4500rpm when the HY35 will spool faster and should still be able to hit my mark but at a higher boost level.

By the way, the GT2871R took a dump so it will cost me $1150 to replace it and still make 375whp at 20+ psi or....

Spend $850 on a treadstone T3 cast mani, tial 38mm WG, and a good used holset from ebay. I will just have to make a custom down pipe, dump tube, and 2.5" hot pipe and I will be rocking 100 more whp for about the same amount of money!

[smelly240]

wow- shame i never go on this forum.

3 years ago i switched to holsets. h1c, now i run a hx35.

bullseyepower housings of course.



if anyone has questions... let them fly.

btw - people have had problems with the newer turbos. best bet is staying hx35/h1c/HY35

[kentuckyslider]

BEP housing? T3 .70ar? How do you like it? I am going with the stock housing and if it doesn't flow up top like I want I'm going with this.... http://www.htturbo.com/thnew.htm the 14cm2 housing, should be close to what you have. Are the BEP T3 housings still available? They're not on there site.

whats up with the electronic **** on the turbo in the link you gave what is that for and what happens when its not pluged in

[kentuckyslider]

It can be removed and plugged but after more research you should stay away from the 2003 and up HE351(it has a small turbine houusing with a 4" vband exit) and the hy35 is only good for about 400whp at 21psi of boost with it's small exhaust housing. I just purchased a HX35W off a 2001 manual transmission truck. Here it is......... http://cgi.ebay.com/ebaymotors...88617

I have seen a DSM make 480whp on a awd dyno dynamics dyno with this turbo at 28psi. They are effecient up to 38psi with the larger exhaust housing. This is all I will need. I will be taking it apart and sandblasting both housings and considering a rebuild before it goes on my car. I will polish the compressor and paint the turbine with 2500 deg. paint before I get my mani and wastegate.

are there any single scroll options for the hx35 and how do you make it spool the fastest

[Reno]

dunno...

but stock hx35...

fastest?http://www.full-race.com/catal...b6978

[johnnyappleseed]

how is this setup for drifting? using the treadstone manifold

[kentuckyslider]

I don't know, I'll let you know when i get it running. I would think it woill be pretty good with my 4.36 R&P? It should be about like a 30R setup with a little more top end capability. I here they spool about that fast. I;m sure it would spool fster with a tubular mani. Can't wait to find out.

which spools faster

[SuicidnS13]

which spools faster

h1c and hx35 spool better/similar to a gt30r but with the top end of a gt35r. 60+ lb/min

hy35 spools faster than both but only supports like 55-60lb/min not over 60lbmin

I have seen many 500+ whp setups on the dsm and honda boards running these setups. I too am building a singled 2jz 240sx with the plans of using an hx52 which should bring me 700whp. The compressor design on these turbos simply rock and their reliability is ten fold that of garretts turbos. All for less than half the cost/hp ratio.

[kentuckyslider]

I to have seen several HX35/HX40 setups on DSM's and honda's making well over 500whp. The 7 blade HX35 should be sick on my built SR in a 2500lbs S13. AS for the 2jz in a S-chassis, that will be my next build for sure. I will be going with a mkIII 5 spd transmission and a single turbo holset HX52 or BW S370. Should be a 9 sec car that is just as streetable as my 11 sec SR. I guy in nashville has a stock bottom end 7MGTE with a GT4094 in a Starion with a 400turbo automatic. He ran a 9.34@148mph last month!!! Thats nuts on a 20 year old stock block toyota.

[2jztwoforty]

both the hx35 and he351 flow allmost the exact same thing 60 lbs/min, the hx40 does 66lbs/min.. the hx52 is the largest of the hx50 series it has a 67mm inducer and a 98mm exducer on the compressor wheel the hx55's only have a 65mm inducer ot sure what the exducer is on those never seen one in person. also the hx52 flow 99lbs/min.

the he351ve's are variable vane turbo's and basicly the turbine housing is ajustable all the way down to i think 4cm2 and all the way up to as much as 22cm2. there was a guy on homemadeturbo.com that took off the electronics acuator and put a normal wastegate actuator and had excelent results with it. you get the best of both worlds with variable vane ,fast spool and big top end. it would obviously be more hassle to run the he351ve's but the benefits could be well worth the trouble. you could also look into the larger he4xxve or he5xxve turbos... any questions feel free to ask i have alot of info on all these turbos. and heres a pic of my old hx52 honda for SNG's

[kentuckyslider]

My turbo was supposed to be here today but UPS has moved it back to the 7th. I already have my tial WG and dump tube. I have to order my mani, some 2.5" pipe for my bigger hot pipe, and some silicone couplers for my compressor inlet and hot pipe. I will be fitting it all up and taking pictures in the next 2-3 weeks. Should I post them on this thread or stat a new one?

I have a few questions about my custom V-Band down pipe. I think I have the rest of the setup taken care of(oil drain, oil feed, and hotpipe etc.)Do you think this will fit between the bellhousing and the steering colume on my S13? http://www.atpturbo.com/Mercha...e=BCSI would like this piece because I can put my o2 sensor and my wideband sensor in it and it has a flex pipe. I figure I can cut my current downpipe to fit and weld a 3" v-band on it. I will just have to get a short piece of 3" stainless tubing and weld v-band flanges on it and maybe put some slight bend in it to clear the BMC? We will see after I get the mani and turbo mocked up before I order anything for my downpipe.

def start you're own thread... i'll be there, but we'd love a few pics and a link to your thread if you'd be so kind...

I ahve a feeling that you wont have much trouble...

[smelly240]

you fellas need to stop worrying about the $ being less for a holset - its not. the turbo will suck unless you get a bep housing and a good manifold.

wtf is this crap about a log manifold? Are you trying to make power or be cheap?

its cheaper to get a 2871 or 3071 t2 and bolt it on with lines.

its only cheaper if you make your own manifold, and downpipe and use the stock housing (lag city)

i have the s13 pictured above, a srt4 with a hx35/agp manifold, and a 1g with a turbonetics t3 manifold sitting outside... all have BEP housings - I tried the stock housings and it was crappy lag.

i get 10+ emails a week with people asking "how much was your setup" and "i have a holset can i use a log mani" - sure you can cun corners - but your dyno will only prove my point.

proper manifolds cost big $heres a pic of the stock housing to compare to the BEP



and the 1g all grimey.

holsets are great turbos - but if you go cheaping out - you wont make big power.

I ahve a feeling that you wont have much trouble...

with that cast mani and the stock housing DOWNPIPE=BRAKEY MELTY FUNTIME!

Did you even look at how my manifold had to be to have a proper downpipe?

look at the new pic - maybe then you'll see what im talking about.

[2jztwoforty]

you fellas need to stop worrying about the $ being less for a holset - its not. the turbo will suck unless you get a bep housing and a good manifold.

well u need to be a little more specific about what housing you had , cause there are alot of diff housing that come on the hx35's i'm guessing you had one in the 18-22cm2 range if it was laggy. The hx35's that come on the dodge turcks usually have a 12cm2 housing and the hy35 has a 9cm housing
