Max boost on standard sti pistons with td05-20g ?
I've got a version 4 type-r with a td05-20g that has apparently been mapped by andy forest to a "safe" 340bhp approx at 1.2 bar.
I've fitted an avc-r to it now and will be getting it mapped and was wondering if 1.2 bar is too conservative or can I eek some more out of it.
Car has unknown pistons, injectors and clutch so take it as they're standard, power fc, walbro, standard tmic, fpr, equal length headers & full decat 3" exhaust
anybody else running similar setups?
Thanks

Your better off with a smaller turbo and a fmic, power wise, I would not go much further than your 340bhp, these cars have been known to let go at less power than this, the rods are the weakest point in the engine and yours are the same as the ones in every turbocharged 2ltr impreza of that year.
The 20g is a horrid turbo for your car, go for drivability, upgrade the brakes, suspension etc and have a nicer car to drive

I ran a 20g on a 2.0 STI engine for 20k @ 1.6 bar (circa 380bhp), sold car to Paul and Liz @ Zen the 20g was replaced later with a VF34 (made circa 360bhp on that) iirc and car now lives with another member on here and as far as I know is still going strong.
Story goes, treat them with respect and service regularly and they will last fine.

Total of 30k on a standard rebuild when I sold it.
And whilst I am at it my wagon I recently sold had a 60k STI engine when I got it, I was running this @ 1.5bar with a MD304 then a RCM 400 ! Engine happily put 18k on at that level and had never been opened !
Too many scare stories on here and I don't usually bother replying but I have actual experience and don't just regurgitate hearsay. (That is no dig at any individual, just fact)
