That's a serious turbo :nod: Would require a forged engine and decent fueling to make the most of it but would be amazing once done :D

I'm running one on mine, with the right supporting mods it'll push over 500bhp :)

Have you touched engine internals or just standard supporting mods man ?

And when does it hit boost ?

Nice build man :)
Bet she's a lot of fun

Was the tial housing a T2 or did you have to take the T3 path ?

SR20 can only take up 400bhp on OEM internals, everything above means changing the internals, at least the spings and valves.
But better taking a stroker or Forged engine

I have a few mates with the GTX, their setups are all E85 projects with built motors, most are aiming for 350kw's on 30psi give or take a few psi

I've only ever used it with Tomei Procam 270's to be honest. When it first went on I had the old style Greddy plenum and standard sprockets and it didn't produce what I was expecting, only 440bhp and wouldn't respond to more boost or timing.

I then fitted Tomei adjustable pulleys and the new Greddy shortport and it made all the difference, engine seemed more balanced an pushed out 507bhp :)

There's another user Actual_Ben_Taylor on the SXOC also running this setup with a couple of small differences and he's nearly topped 530bhp :)

As for the response, my graph is linked to on the first page, I upped the limit to 8000rpm to help keep the power range in play. Dropping the cam size would help spool, but I'd be cautious of going too mild, maybe to a Procam 260?

527fwhp with 2.0l bottom end, haven't ran it up with the new 2.2 setup.

I also had the Tomei 270 Procams, but I'm going to be switching to the Kelford 188-B with a set of custom DLC coated rocker arms...

cheers for that mate, you answer another one of my questions about intake manifolds while you were at it. so either a 260 - 270... mid range response for sliding..
