Nav Posted April 6, 2012 Share Posted April 6, 2012 Hi guys,When choosing pistons, what is the best compression ratios to go for when rebuilding an engine. I know the better the compression ratio the more power.. (or am i wrong). but i also read its not good for the engine.. so what is the safest ratio to go for. I read its 10.0:1 for standard B18C4 engine.. (from Wikipedia), is that correct.. ?? Any info would be helpful guys.. Quote Link to comment Share on other sites More sharing options...

weetec Posted April 7, 2012 Share Posted April 7, 2012 if your taking the engine apart then there is your car off the road for a wee while....keep it running and buy another engine to work on....dont rush it!. im building an engine and it may well take me a year due to finances.... starting the bottom block first.... b16b oversized pistons, new oil pump basically everything new. i allready have the teg cams, springs etc etc for the head... the way im looking at it is to do it once and proper. and im still motoring with my current engine which i will sell towards the end of my built engine. that way i will get a little money back.
