looking into a swap f22-h23 - Honda Prelude Forum

mako308 · 11-20-2010, 04:00 PM

here in the near future (about 2 month or so) i am going to be pulling out my f22 motor and wanting to swap in an h23a1. which i will eventually rebuild for boost. but until then i will leave it stock.

my questions are..
> can i use my f22 wiring harness?
> which computer would be best to use? just a regular h23a1 5speed ecu? which ever one will work with a tuning software. since its obd1 would hondata s300 work? <-- for later use.
> im assuming i would have to get h23 axles
> would i have to do any dizzy harness switching?
> and any trans recommendations for the h23 or just stick the with h23 trans
> i am assuming that i would need h23 motor and trans mount. but should they bolt right in?

the car is a 92 with a spun rod bearings f22a1 motor. it is white in color, stock all around, with broken rear windshield. its the way i bought it. ill just describe it instead of posting pics.

Yes but you'll have to add a few things
P14 is the stock and no it does not work with hondata
No, axles are the same
Use your same distributor
M2S4 would probably be best, taller geared but not too tall
I'm sure the mounts are covered somewhere but they will bolt right in.

thanks for reply. so i will need the p14 just find another tuning software when it comes time. right? and im assuming that m2s4 is the stock h23a1 trans?

and would it be easier to just use h23 harness instead of adding the few or is it not hard to add them>

Well if your not good with wiring I've seen H23a1 harnesses go for about $60 on eBay which is a pretty good price for a complete engine harness. P14 is the H23a1 ECU and M2S4 is the trans that comes with it.
