what ecu does the 03 ex have...is there a way to change it to obd1 with a p28 or something like that?? can you puta d16 camshaft in it? or are d17 in a whole seprate class?

 

Nothing is swappable between the D17 and previous models. They're of completely different design, unfortunately. The closest you can get, is modifying a y8 intake manifold to fit the D17, so you can get rid of the plastic one that comes stock. The same goes for the ECU, they're not alike.

 

ok cool...thanks

 

your selling an obd2 honda civic ecu? if you are im interested let me know
