3.1L M20 stroker

[CarsSuck]

So what exactly is involve in building a 3.0L or 3.1L stroker? IE's kit includes custom pistons, but uses the factory rods.

Other than the crank, what is needed to complete the build?

[digger]

minimum is s50/s52 crank with customs pistons to suit m20 rods/s50 rods or custom rods.

Also need new crank pulley bolt and spacer for front oil seal otherwise thats it.

depending on the rods used there may be clearance issues with the block.
