It's going to be mostly a street car. so you think ill only be able to pull out 400hp?

 

You will be fine with the older HX35, it is said to be identical to the WH1C in the older 12V trucks. It is good for well over 400whp with 52lb/min. I was getting close to 400whp with a 42lb/min GT2871R. It will spool much faster on a B-series or a H22, what motor are you putting it on? It should be a fast ride in a 2000lb CRX reguardless. BTW, where are you at in Western Kentucky. I'm in Hopkinsville. I've got a 2600lbs S13 240sx that should be in the 10's with the HX35 and a good stand alone EMS. I ran a 11.7 at beachbend in BG last month with my old GT2871R at 21psi.

 

Only 400whp in a Honda??? That will run with any production car in the world and most 600cc bikes. Anything more than that will not be very "streetable" on a 1.6 liter IMO. How much does your car weigh, and what is the fastest car you've ever owned?

 

Can you get me a price on a .70 ar T3 BEP housing for my 7 blade HX35?

 

Fastest car? either my all motor H22 EG, or Ls turbo on 6.5lbs. but those aren't fast enough. I have ridden in my buddies old hatch that was built. LS/vtec bored to 2.0L made 450HP on slipping clutch with the HY35. I was hoping to put out 400-500HP.I want to make sure I can keep up and BEAT bikes. To many people around where i live think Bikes are the only fast thing.

 

I'm near Paducah. Not too far from Hoptown...The turbo will be going on a z6 vitara build. I'm trying to decide what manifold design to go with to get this thing to spool before redline on the single cam. I'll probably try to incorporate a quick spool valve to help this along. I'm wanting to run 6's (1/8) with a single cam in a bad kinda way. But if I can't, I have a 8.5:1 gsr motor going together right now that will do it!

 

You need to get down to clarksville TN when you get your car done. They run the 1/8th year round on Saturday from 1:00-dark. My best time in the 1/8th is a 7.55@93 with my old setup. I should be close to breaking into the 6's with the HX35 on my rom tune and 72lbs injectors. With a stand alone and some 1000cc inj I should be able to push the HX35 to it's limits. I might need a BEP .70 ar housing to get the most out of my non TS mani.

6 blade HX40 pro should get you the numbers you're looking for. DSM's make over 600whp at 30+psi with this turbo. I've seen a HX35 make 360whp at 14psi on a SR20. I have also seen a HX52 make 400whp at 8psi on a H22 but they are very laggy. You could get 500whp at about 28psi with my HX35 (7blade) or you could look for a WH1E(older version of the HX40) flows a little more than the 60lb/min that the HX35(7blade) does.

I'm sure this is in here somewhere but I'll add it anyway. This is what these turbos are capable of on a well tuned engine with supporting mods.......

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) ?

HX52 600-800whp (never seen a dyno but compares to GT4094 or GT42) ?(80+)

 

what kind of numbers are people making with the h1c?

 

The H1C is the older version of the HX35. Diesel techs say it is identical to the pre 1998 (8blade) HX35. It 's performance numbers should fall inbetween the HY35 and the (7blade) HX35. The only problem is it's stock exhaust housing is to big for your average 4cyl to spool it before 6K rpm. My HX35 has a 12cm2 housing and the older H1C has either a 16cm2 or a 18cm2, that's just to big for a street car. The HY35 has the smallest housing of any holset mentioned (9cm2) it spools like a 16g or GT28 but chokes out at about 25-28psi just like they do. The HY35 will make the same power as the H1C but spool 1500rpm quicker on our engines. You really don't see anyone running H1C's with stock turbine housings, most have BEP .55ar or .70ar housings.

 

You know I will be down in Clarksville at least once with the starlet. got my hy35 cleaned up this past week. Cut off the wastegate bracket and polished the compressor housing. Then chopped off the funky 4" v-band and plugged the wastegate port. Going to weld a new 3" v-band onto it.

i don't really feel like reading this entire thread so i will just ask the question.

i just bought an hx35w. it has a 8 blade wheel on it. i compared it to my friends older hx35 and he has 7 blades.. my wheel is about 8-10mm's larger also...


think i am good for over 500?










he said there was some work done to it. I pulled the compressor housing and it has red letters on parts.. i duno. im new to the hx35's


just to add on to my post

its a 16cm exhaust.

heres what he posted in his for sale thread.

Holset Turbo Model HX35W, has a 4" exhaust outlet, 8 Blade compressor/turbine wheel, this unit is NEW part number is 3597508
H-CHARGER 60/14W Stage III quickspool hybrid HX35/40W HOLSET TURBOCHARGER list new for $1250 complete with housing selling for $1000 obo.............

 

That's a bad boy!!! You have a 8blade HX40 part#. I've seen a 4G63 with 650whp at 32psi on 110 race gas with a similar turbo. Take a close up of the tag. Sounds like a straight HX40 with the 16cm2 housing, but the hybrid HX35/40 have the 35 hot side with a HX40 compressor. You have the HX40 compressor wheel. Should be good for 70lb/min flow. What engine are you putting it on? I would get this housing for sure.. http://www.theturbotrader.com/index.php?cPath=49_22_25
You will spool at least 500-800rpm quicker with enough flow for 600whp. The 16cm2 housing is to big unless your running a H22 or K24 IMHO.

 

sweet deal. that ex housing will bolt straight up, correct?


i am using it on a built stock sleeved gsr at the moment. i am building a 2.0 liter b bomber in the summer. i just wanted to get my turbo setup done in the winter.

 

best i can do



82mm

 

For the HX35 series

The 8-blade wheels measure 54mm on the inducer
and 83mm for a major diameter.

The 7-blade wheels measure 54mm on the inducer
and 78mm for a major diameter.

 

That's a HX40 wheel and yes it will bolt right up. If you get the BEP housing from theturbotrader I'll take your 3" vband plate of the back of your 16cm2 housing for a good price. I need it on my HX35 setup.

 

I can buy a Holset for cheap... but i dont know which model it is...
maybe the pro's here know a bit more

 

i was thinking about using my h1c i got one my next project car i'm in the market for now. I am either getting a 93 accord or a 91-93 teggie. So from what i'm hearing the h1c is to big for those engines. Will i be able to use a different exhaust housing?

 

A H1C is a less efficeint HX35 capable of over 400whp at high boost. I would not use it with less than 20psi. These turbos like high boost. BEP T3 .70 ar should be fine. I'm not a honda guy, what motors are in the cars your looking at? If you want 300-400whp at 15-20psi I would get a HY35 or it's big brother, the HE351. Both have 9cm2(about .48ar) exhaust housings and will spool up quick even on a single cam. They spoool like a 16g and make power like a GT3071R.

 

^^^ I think you might be a bit off on that estimate. I know Blundy has made 423@22psi with a badly slipping clutch on an hy35. If you want the exact numbers, Zex found what he said and quoted him on pg 63.

And here is another place he states he has made 450whp on the hy35.....

https://honda-tech.com/forums/showth...046&highlight=

Maybe somethin to remember is that honda engines seem to be very efficient so they use less boost pressure to make the same whp levels. I know the setups could be very different but even 423@23psi is a LOT better than 365@20psi. Every engine is diff, but hondas are on average quite efficient.

And yes the hy35 is a very good street turbo. I have it on my gsr and it works quite nicely.

 

Yes, Honda heads flow better than most 4bangers. For instance a B18 flows 260+ cfm with a stock head while my SR20 flows 220cfm. The only problem with big WHP setups on the HY is the small exhaust housing. It's said to be limited much past 22psi and completely chokes out at 28psi. I make 375whp at 22psi with my GT2871R and after that it becomes a heat pump. I would assume with the better flow of the B18 you would make better numbers with my turbo as welll as your HY35. The HY is said to flow 52lbs/min and most hondas will make 10whp per lb/min of flow, that's 520whp if you want to push it till it pops. I would say a good safe boost level for the HY is 20-22psi and somewhere around 400whp depending on the setup.
