Well ive been sitting here crunching numbers and figured id plan the monster S2K build i have seen the toyota 2jz swaps the chevy ls1 and the ls7 conversions in our s2000's but with that kind of money lets keep the honda thing a honda i love the high rpm's of our hondas but the power of big blocks (i build racing blueprinted chevy crates on the side of my aviation mechanic career) so i got the idea of a boosted stroker which we can benefit from the torque of the na area and top end of boost. me and my cohorts have came up with the boosted 2.7 stroker (almost a 2.9-3 but getting bad results might take a little longer) as for prices for this dont ask yet

 

This has already been discussed many moons ago. The 2.5 is about as efficient as you will get. Money wise it isn't worth it with the headache and problems with compression. The motors are already tight, either LS2 swap your s2000 or just boost her ")
