No one has done this. Too much work, just swap a QR25DE. WAAAAY easier.

Im going to be nice because this seems to be your very first post on zilvia

you don't need anything for a sr20, they have this nifty thing where they are turbo from the factory and as such are fairly tough in stock form

now the question that needs asked is what are your plans for this engine and car? for road racing and autox you wont need anything, for drifting and bouncing limiter rocker stoppers are nice to have but aren't really needed, get some small diameter intercooler piping, a wideband, a boost gauge and learn the car before making changes to anything

this is the only chance you get at someone here being nice, don't squander it

Don't get rocker arm stoppers, they do more harm than good.

You want reliable? Leave it stock.

Jorgs_7 · 09-09-2016, 02:09 PM

Keeping it stock, on stock ECU requires nothing much besides a wiring harness.

My vote:

Gasket kit
MLS H.G. (Cosworth IMO)
ARP head studs
T28 (not some POS ebay turbski)
CodyAce manifold with Tial 38mm External W.G.
JWT S4 cams
850cc inj.
AEM ECU (Soft fuel cut, no fire balls, but no rockers exploding)
3" exhaust
FMIC
Boost controller

Scope the "GTX2867 thread" for proof of 400 WHP. (T2 turbo stuff)

I think the general consensus about SRs, is once you go T3 turbo, it's going to be unreliable. (without loads of cash)

Truth, bent valves are more expensive than thrown rockers

No it's not! The consensus when going T3, is it better make 500hp plus! If not everyone is clowning you behind your back!

Kingtal0n · 09-12-2016, 07:16 AM

ha! where did you get that from? From me?

cotbu · 09-12-2016, 07:18 AM

Probably, but it's true.
