whats a stroker?

[MR 325]

This really has been covered way too many times. Do some research.

stick with 2.5 they make more power. if you want 2.7 you will need a 325e crank from a m20b27 or you can use a m52b28 to stroke to 2.8 or you can use a m54b30 crank to go to 3.0 or an s50b30 to stroke to 3.1. the list goes on for what can be done.

Can someone either help with a run down of what parts achieve what displacement sizes. I have a running 2.5 m20 and a complete bottom end but needing a rebuild 2.7 m20. I also have 2 complete sets of 2 different skirt size pistons and rods from I motors. I was wondering about other blocks,cranks,and rods that can give most bang for the buck with out doing a complete motor swap from another car needing tons of supporting parts to run. Low budget bang for buck.Thanks
