I'd say this topic has come up alot, in other forms besides this one. But im buyin a 93 hatch an i wanted to do a motor swap that not alot of ppl around here do, most ppl just do ls swaps or si swaps but i wanted something with alittle more hp. An i know both crvtec an lsvtec motors are good once you get them set up an running good. But which motor would be better for racing as in reliable, more horsepower etc etc... Thanks

the one with more displacement will make more power. if you say you have the money, sleeve the ls block and bore it out. it'll be much stronger than a straight b20 block. and build from there. also, do you want to run it boosted or NA?

i like the torque of the b20 out of the box, plus the b20z (jdm b20-b/z? cant remember right now) has higher h/p out of the box as well, ~140 hp, 133 trq

but a stock b20 can be boosted to hell resulting in "WEEEEEEEEEE..." etc., etc,

DONT GO LSVTEC! WHy? Because you mention that you want a reliable motor. Imo no oil squiters and a bad r/s ratio dont equal reliability especially since vtec motor make most of their power at top end. I also wanted to go ls vtec but with some research Ive decided otherwise. Heres what I found
http://www.h s t u n e r s .com/news/wmview.php?ArtID=33 but if this is not an option than I would say crvtec, as the one that I drove was stock except for the 75 shot of n20 skunk2 manifold and boltons ran a 12.3. Just retype the link with out the spaces, for some reason it keeps getting blanked out when I preview post. Hopes this helps

with a properly balanced and built bottom and top end, an lsvtec can see 8-9k no problem.

blue printed, built whatever still lays the fact that the piston will draw uncessary force on the cylinder walls due to the r/s ratio. None of what you mentioned changes the r/s ratio, but being built does help. I dont see nothing wrong with other people doin it, I just wont. True theres a decent amount of power to made with either cr/ls/vtec but I still believe reliabilty is an issue, just might take longer in a built motor for things to go wrong.
