have a 90 accord (F22A1) that is in great shape but #3 ring landings are cracked. Ive ordered a F22B with engine wiring harness and was wondering if there was anything I had to replace.... I know I have to use the old intake but aside from that will everything else work? Will I be able to use the old ecu?

 

What plateform is it? JDM DOHC non VTEC or JDM F22B SOHC VTEC??

I would do timing belt, balancer belt, water pump, valve cover gasket, oil pan gasket, front & rear main seal.

Get a P39 ECU if I'm not mistaken, cause that ECU is for the JDM F22B DOHC.

Why would you need to swap IM?? Usually when people drop these F22B DOHC in, they don't do that.

 

you will be able to run the old ecu.

 

I was told the sensors are different and the plugs wont match. For example the MAP is in a diff spot and the are some vacuum line in differnet spots as well.

 

you have been told wrong my friend.

the only thing is the lack of iab's, but you can hook them up to vacuum only instead of the vacuum and ecu trigger.

 

^^ x2!
