well, you can get some wicked HP#s if you put in a b18c1 with a stage 3 revhard turbo kit. Don't quote me on this but I think the #s were around 350-400HP. BUT I think they did bottom end work on the block. LS engine can handle more boost like ACCORDLVR said and the taller gears will allow more time for the turbo to acheive boost. Search the web (or AF) for clubs or what not to see what type of numbers people are getting w/TC LS engines. The possiabilities are endless but it most likely will be w/turbo unless you have a thing for all motor.
