5sge

[phrogmodz]

im in the process of building a 5sge at the moment.
i have a 5sfe block and a 3sge head.
anyone done this before?
the factory 5s pistons are dished with collets
cut out for valve clearances and the 3s pistons have raised
tops with collets.
what im after is factory compression ratios for the two engines
and a compression ratio of the hybrid if anyone has gone
down this track before.im avoiding cc ing the heads to calculate
the ratio or doing 1mm oversize mr2 pistons if i dont need to.
1997 sxv10 5sfe
1992 sw20 3sge
thanks

Have you checked the yank mr2 board? There's a full write up on what you need to make your 3S-GTE into a 2.2L stroker with the 5S block, so it's pretty much the same to what you're doing, since IIRC, Nemesis did say the 3S-GE head is almost identical to the 3S-GTE head.

3SGE CR = 10:1 although not to sure about the 5S-FE, probably very slightly less if not the same.
