Recommendations on a Holset turbo

[bigal07]

I'm just looking for some input on my situation. I built my 95 gsx originally as a 300 hp or so car, no internal mods just turbo, fuel, air mods, that sort of thing. Well i ended up running like that for awhile with these mods, evo3 16g, greddy xl fmic, turbo back 3" exhaust, tubular mani, dsmlink, greddy profec spec b, intake, walbro 255, bov. Anyways awhile down the road i stroked it to 2.3L, act 2900lb, fidanza flywheel, bc 272's, 880cc pte's. With this new set up i havent drove my car much, mostly because i went half throttle at 15psi on the evo3 and hit 325hp on dsmlink, maxing that little thing out. I'm shooting for around 500hp, I have been looking at Holset turbos my main question is should i get a HX40 to do this and get a different manifold or switch housings, internal or external gated and which holset would really suit me best. Thanks for any help.

you can get either a hx35 or an hx40. that is just personal preference. the only thing you have to worry about with a holset turbo is getting your oil pressure down.

UHHH, theres plenty of people who have put down well over 400whp on the e316g, which is 500 crank hp. You're not close to "maxing that little thing out" at 325hp
Given you have the supporting mods, crank that e316g to 25-30psi and report back with some numbers
But anyways with a stroker, I would probably run something larger than the 16g. I would probably go right for the hx40 6 or 7blade in a t3 ar.70 turbine housing. This should give you enough turbo for 650-700whp. Should be able to make 500whp somewhere between 25-32psi given the right tune and parts, I would have to guess.

325 is not maxing that turbo out. crank the boost upto 25lbs and watch it hit the 400+whp range.




Edit: toofast82 beat me to it.

He is stroked and even if he did max it out that turbo will run out of breath and power will drop like crazy. To get a good strong power band he wants to get an hx40 that will actually feed it enough air.

get a 60-1 garrett. spools faster than a holset and will make more power for dollar!

Want to be a little more specific about the 60-1, maybe even some comparison logs?
Which turbine are we talking, T3, P-trim?
Which holset are you comparing to? An hx40 in a 23cm housing
Don't just say random stuff without any proof

holset 35 with a bep housing.

Fing prove that one!! A Garrett 60-1 is $1150 I paid $450 brand new for my H1E and will flow just as well.

I haven't read a post that falsely informed in quite a while. Have you just awakened from a coma?

I have less than $750 total in my HX40, and it has the capability of generating the same airflow as a GT35R ($1300). Even when comparing the HX35 to a 60-1 which are closer in terms of airflow, the HX35 stomps the Garrett in cost, reliability, and spool.

I have had a 60-1 and now a HX35!! Will never go back

I'm definatly a believer of the Holset, I used to think a 60 trim garrett was a good turbo then i slapped myself in the face and opened my eyes. Just one more question, could i just weld on a t4 plate onto my mitsubishi flanged manifold, i have a welder and the skill just wondered if anyone has done it that way instead of buying a new manifold or new hot side.

There is a hugh difference between the mitsu flange and a t4. It would be best just to source a t4 manifold or just make your own, I did.

 

[bigal07]

Did you start from scratch or just weld on different flanges?

I built it from scratch. Bought the flanges and alot of U bends and started piecing it together. Here a link to the finished manifold, post#527
