Hey all,
I rebuilt my 1.8 JH 8v engine about 8k ago. Now I wish I would've installed some 10:1 pistons. I recently came across a set for $50(is that a good price?), and was wondering how feasible it would be to install them in my '83 Scirocco. Can I just remove the head and oil pan, disconnect the rods, push the old pistons(not oversized) up out the block, then put the 10:1 pistons(think they're from a GTI) with new rings onto the old rods and reassemble? Would I have to rehone? Should I replace the rod bearings and bolts even though they only have 8k? How much more HP can I expect by going to 10:1? Should I use the 10:1 wrist pins or the current ones? Is this a very common mod?(that's usually a fair indicator of if it's worth it or not). Wow that was a lot of questions! thanks in advance, every little bit of info/opinions helps!-
Rob
