Here in PR we have a couple FSDE engines running over 600whp, 1 of them was a daily use Protege5 and they only have Pauter rods, Wiseco/JE pistons, ported head (no valve job), regrind cams, balanced crankshaft and modified transmission.
That is not all, right now in this moment, while I build my FSDE, my builder is already working on an auto trans to support 800+whp that his engine is now pushing. The GTX gears are not holding that much power.
The 800+whp FSDE does have a lot of custom job, new cams, larger valves, springs, retainers, crankshaft, pistons, rods, etc.
So far, it has been proven that with the right parts, this engine with STOCK head, some porting on it and on the Intake Mani, can do 600whp.
