I also want to use the silvertop bottom end but im unsure what pistons to use, will my 16 valve pistons fit the 20valve conrods or what would people reccomend to do to make a good engine from my 16 valve head and silvertop bottom end?

Your 16V pistons MAY fit, it depends on if your 16V is before 1987. Most AE86 came with a "smaller rod" so the pistons don't always cross over.

Great stuff thanks for the info, i will be stripping it down in a weeks time so i will know then. The 16 valve head i have has ex and inlet port work carried out and is already fitted with mild hks cams around 264 degrees if i remember right, should i go and get the combustion chambers matched and what else would you do on a budget if you were building this engine from the engines i have, thanks for any info
