hey guys i want to change my internals to forged ........

Question ......does anyone know the original size of the cylinders ?..
Cuz the Forged Piston Kit that i got was 86.5mm , which i think is a .020" Over bore ?

Do you guys think it is wise to bore out my block ?

lol, what engine do you have under your hood or in your garage......if you have a 3s/series engine, hmmm, youll have to bore it out.....and i think that if you have the 5s/series engines, your piston diameter is too small , and you will have to sleave the cylinders....hmmm, i aint no professional though, so maybe someone else can verify for me....but could u pls input what type engine/car u have so it will be easier for ppl to help you..

boring out your block .020" over won't pose any problem
