Considering that the BB and GTI-R engine are supposably the same except for the three things listed I would like to know how much of a difference the individual throttle bodies make. It's cool and all, but if I would say get a BB and swap the stronger rods in and ...i know the hp gain on bolts is zero, but they are saying BB = 105ps = 102hp and the GTI-R = 120ps = 117hp is just from the throttle bodies? I noticed that BB's had 8.5:1 compression where the GTI-R had 8.3:1. Are they running more boost in the GTI-R? What's the 15hp coming from?
What motors come with piston coolers?
I was in a argument with a couple of friends on this. One says all DET motors come with Piston squirters, and one says only Some high compression NA motors, and GTiR motors come with them. One has a BB DET and he says he saw squirters in there when he rebuilt the botom end. Just wanted to put a end to this. Thanks.
