Is it possible (and logical) to stroke a b18 to 2L and make the compression ratio around 8.5:1 to 9.0:1 for a turbo application?

Also which engine would be best to use: the LS non-vtech or the GSR vtech engine?

 

Instead of stroking it, have the block sleeved and bore it to 84mm, that way you keep the same geometry, and don't make the r/s ratio worse. OEM crankshafts are excellent, no need to replace it...and then your sleeves will be stronger and be able to handle more boost. It's possible to get whatever compression ratio you want, depending on what head you use...LS/GSR/B16. As for what engine, use whatever you already have. If you have an LS, you can always put on a VTEC head.

And it's VTEC, not VTECH.

 

Whats r/s ratio?

 

The ratio between the length of the rod and the stroke of the crank.

 

the ls would actually be better for boosting because of the already lower compression ratios.......stroker kit ruins the r/s... the good r/s ratio of honda engines is what give them excellent reliablity with high revs
