Stage 3 on CA18 with GT28R?

[technician]

I've got one of your stage 2 chips and I'm thinking of buying a GT28R.

Is it worth upgrading to 444's, Z32MAF and a stage3 chip with the GT28R?

The engine is basically standard CA18DET with fresh rebuild and CA16 inlet cam.

What sort of power output could be expected on this turbo at either stage 2 or stage 3?


p.s. I have already fitted a big Apex FMIC, turbo back 70mm exhaust, big air filter and uprated fuel pump.

The GT28R is pretty much the same as the S14 T28 - it'll work well with the stage 2 ECU ugprade at 15psi (~260-270bhp) or 17-18psi (280-300bhp) with a stage 3 setup.
