I am looking at puttin an rb20 into my s13 pretty soon and i was wondering where many of you got your engines. i was looking at jgycustoms or jarco inc but i dunno if jgy sells a tranny with it and if the engine is any good, i have read some comments about them but none about there engines. and my buddy has a jarco inc engine and his seems to be fine. just looking for anny more options.
