hi i have a 1990 accord with an f22a1 non vtec engine i want to swap it for an h22a vtec will the obd1 ecu that is hooked up to the f22a1 engine when wired to the h22a vtec be able to tell the vtec when to kick in or do i need to get a vtec controller. or do i need to buy an obd1 p13 ecu. another question i have is my acccord is an f22a 5sp will it hurt the power output of the h22a vtec engine to bolt up my f22a1 manual transmission i was hoping to save some money by just buying the longblock without the transmission my transmission seems to be in great condition. my main concern is the vtec isue with the f22a1 accord ecu. and one more thing can anyone tell me where i can buy a manual tensioner conversion for an h22a vtec.
