Hello. I have a 1986 honda prelude that the heads are about to blew out. Just yesterday i purchased a 98 prelude that was involved in a rear end accident for $200.00. It has the h22a4 engine in it and the engine is perfectly fine. Thought i got a steal. The air bags did deploy on it and im not sure if i need a new ecu because that happened or, if it will be usable.. this is my first engine swap ever so im excited. I need the h22 standard transmission. It has an auto but i am not a fan of automatic. Would that require a new ecu as well? And for now im not sure if my f20b transmission will work on the h22a4 till i can get the h22 tranny. And info or cheap h22 tranny for sale would be nice. Thanks.
