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.

I had to make a sacrifice somewhere. also with what i was tuning with honestly 1 bar was all that i suggest going to.

* 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....

Was?

what happened? Did you sell it before you went over to JDM land?

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.

Anything SR related automaticlly makes your 240 Queer, its like a STD WD

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+)

TWIT @RB30DET

so if i do my math correct a ka with a TS mani would spool 10 psi on a hx52 @ 4300 rpm hmmm

No the car is stored in a garage.

"BIGGAMEHIT, you should really consider the turbine housing in the link above. It has enough flow for 650whp at 32psi on a HX40........."

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.

"Biggame, how did you slide your car around with no power steering? Converted it to a real manual rack? Must've been difficult."

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

Truth is Treason in the Kingdom of Lies - Ron Paul

Ok, now i hate you too

J/K....i'm so jealous . One day i will go over there for vacation and hope to bring back all kinda of jdm goodness

Here is a link to my build thread on the SR board....

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.

i was gonna keep it a secret but i got a he351ve in the works, yes with a KA

Sorry, it didn't like the name of the server that the picture where put on

Also, anyone know of a place selling holset turbos? Ebay doesn't have any hx25's listed, only the bigger ones.

there fixed ur pic 4 u
