Hey guys im a little new to this site and to hondas so bear with me . Well i just picked up a 1990 crx hf and it is well... really slow. I just went to the local salvage yard and found a 1991 integra ls. The guy said you can have it if you can get it out...... so i was like haha its mine!!!! I got it out ... what will i need to do to fit it in my car... will i need a new ecu? I am already searching for a 1989-1991 crx si tranny i heard those are the best. Will the si tranny bolt right up to the ls motor? Also is anybody awhere of a website that sells rebuild kits for the ls motor just to make sure... other than that any other info from anybody who has done this swap would be reall really helpful thanks a bunch guys.
