Engine Mechanical problem
1993 Volkswagen GTI 4 cyl Two Wheel Drive Manual

i have a problem with engine, its a 2ltr 8v gti, I went 1mm bigger on the bore, its now an 83.5mm piston, the engine knocks when I swing it, as I remove the spark plugs the knock subsides, my only guess is that the compression is too high, it gives a reading of 1200-400 kpa per cylinder, how do I overcome this problem, I havent started the car with these new mods, I hav the intake manifold and exhaust disconnected. The knock worries me
