I'm with Rick on this one. If you don't want massive power, that is 200++bhp, stay with the .36 housing. It makes a very responsive and fun car to drive. Can still produce the 200 and slightly more although anything over 200 is pushing the turbo. I changed mu .36 T3 to a 4x4 spec T3 and regret it. To gain a few bhp high up the range doesn't compensate for the better 2000-4000rpm power the smaller version had. If you want 250+bhp though, then you need to abandon the .36 housing.
