wat up guys im new to this site i actualy never knew this kinda stuff was available i have a 92 prelude with a swapped motor i now have a f22b non v tec engine in it i think it is still running on the old ecu unit if i can get a jdm ecu unit for the f22b how can i do the swap and is it hard ?Do i have to change the whole wiring harness ?

i have done plenty to this car myself and will list the stuff later gotta say hondas are fun !!! by the way i think im not too sure but the old engine was a h23a ?!?!

Well, you went down in engine quality. Honestly I've never heard of anyone going H23->F22, so I don't know what would be needed with wiring. Finding an F22b ECU shouldn't be hard.

well the guy i bought the car from blew the h23 motor thats why i went with the f22b it was cheaper plus i do like the engine it is surprisingly strong and has a high quality rating !!! i just want to know if im gonna do a ecu swap from a h23 to a f22b is it plug and play or are there modifications to be made

It's an accord site with a lot of F22B guys around.

I'm not sure about the ECU either
