Last time I dynoed my golf before rebuilding the engine, I got 215HP with the 502's inj, and stock head,,, I just finished putting the engine together 2 days ago, I installed a nice ported head, rosten rods, new nural pistons, rings, R-520's inj, a higher lift colt cam with lash caps,,, it took me a week to do it, cause I could only worked on the car 2 to 2.5 hr daily,,, now I am driving it and I got 100 miles so far on the odometer, car has definitly different sound now, deep sound,,,, I am in the process of braking the engine in, I am going to see how far the 17/22 goes, then I will replace it with a bigger or a compound turbo, we'll see down the line what I could do to it.
