I am going to install new pistons/cylinders,and refresh the heads.
Quick question. I am keeping the fuel injection on my 1.8L. So should I keep the stock 93 MM cylinders,or go to a 96MM aluminum for added cooling. If I go to the 96MM will I run into drive ability problems??. http://aapistons.com/products/vw-porsche-9...der-kit-914-bus. My compression went from 90 PSI hot motor throttle open to 150 PSI with a few drops of oil. Can I do this cylinders myself???. Thanks for any advice or suggestions. |

With the pushrod tubes out remove the lifters (IMPORTANT KEEP THEM IN ORDER) take two lifters hold them face to face up to a light.
They should be be slightly convex. If they are flat or concave, any pitting they are done and it's false economy to not rebuild the bottom end. Good luck (IMG:style_emoticons/default/beerchug.gif) |
