dude buy a blow gsr motor and re-build it with with type r internals or whatever just keep it around 12:1 compression, some nice cams and and you will have a motor around 200hp to the wheels

or better yet go b20 vtec but rebuild everything before you put it in, talk to the guys at yonke racing i went there for my build and i got 223whp/181fpt from my set up. i spent around $4500 on my setup.

also i have seen online some companies sell fully build all motor swaps for around that much too.
