[G22DET]

well, that's what he's doing right now...researching by asking questions here.

yes, the injectors from the Z32 will fit but u'll also need to get the fuel pump fromt he Z as well...you'll need to get that if you are aiming for 250hp. 370cc is good enough for 250hp, especially if you are gonna boost 1 bar.
to change to a different turbo such as the t3/04, u'll need to get a different manifold...if you wanna keep the same manifold (and if money isnt an issue) go for the HKS GT 25/30 ball bearing!! that'll do you good up to 300+ and it's ultra responsive. a TD05 will also fit on the facotry BB manifold too.
250hp isnt such a distant goal though if you are not planning to swap turbos and just use the factory t25. a 3inch exhaust, properly tuned ecu, the larger injectors, and if you boost 1 bar, should be no problem and wont max out the turbo.
