Re: Nissan Guys.. (Boostage)
Bore x Stroke on the RB20DET's are 78mm x 68.7mm, it's not a very good motor. Head flow isn't great, internal parts are weak, has problems with oil/water pumps, and generally just isn't great. An RB25DET is a great alternative, out of all my friends with GTS-T's most of them have swapped to RB25's because they're so much better. The one that hasn't is making 270 RWHP out of his RB20DET with a bigger turbo and 15 psi, and it's pretty weak.
