Bore more cool than stroke.

I would add more bore and stay with the stock stroke. The most you can go is 88mm with out having to sleeve the block. I would send my block to mazworxs to be machined.

88mm huh mazworx recommends sleeves for 87mm will that have cooling problems with that big of a bore? ?

Your forgetting this is the turbo section. lol I wouldnt go 88mm on a turbo motor. Youll have more benefit from staying with the stock stroke, 87mm bore with a bit higher compression than stroking it.
