What hp are you aiming for? I have seen the 350hp rated GT25 making 225kw at the wheels on a 1.8 litre CA18DET, max boost was 25psi, which was available by 3500rpm.
Whether you choose the 290 or 350hp GT25, make sure you get the .64 A/R exhaust housing if you want full boost between 3000 & 3500rpm. Whilst it sounds like a small housing, it has no problems flowing the exhaust gases for the abovementioned 225kw.
The smaller 290hp turbo will be much easier to physically fit, the 350 hp one has a very large .70 A/R compressor housing, which is big enough to hit the exhaust manifold on most factory manifolds!
For my dollar, i'd be going for the 290hp GT25 (which I am in fact fitting to my 4AGTE) Its a bonus that its almost $1000 cheaper too, as they sell shitloads of them as bolt on upgrades for nissan SR20's
Cheers
