dx and ex are models yes but a crx is a completly different think thats a car which came in base,hf,dx and si. ls motors came from yes the acura integra meaning dohc so check it. if it has a sohc then she was wrong. as for your rims well go no bigger then a 16. any bigger and your not tuning your ricing imo. as for the interior section. well the seat mounts are raised off the floor so i would see no reasons as to why the seats would basicly sit on the floor. sparco i believe makes seat brackets that are bolt on items. but there a bit pricey. last but no least engines. well warped piston i doubt a solid piece of metal as big as a piston would ever warp. but if it happens only when its warm then it could be a few things. fuel spark sensors. it jsut depends on if it truly does have a ls motor or not. because if it does im guess it was a bad job gone worse.
