Most cost effective EM for NA H22? - Honda Prelude Forum

ThatPreludeGuy · 03-12-2006, 11:26 AM

So there's probably a great post somehwere detailing this out but I can't find it yet. I'm getting closer to finalizing my parts list for my motor swap and I realize now that I should probably have a good idea of cost for a EM for my build. The build is a very mild NA JDM motor and should contain the following when done.

JDM H22A
Iceman intake
King ported TB
BlackTrax Stage 3 IM
AEM Pulleys
RS*R top half header w/JDM downpipe ~most likely switching to Vibrant down the raod
2.5" Random High flow cat
Apex WS catback ~ thinking of a better catback later with less restriction
Eventually Crower Stage 1 cams and adjustable cam gears
Adjustable FPR

So in doing this I'm staying OBD-II initially however I have no objections to going OBD-I as long as I can swap back for that pesky emissions testing we do here in NJ. So with that list what makes the most sense from a cost perspective to in the hp/dollar ratio?

Go with Crome/Uberdata on a P28. Switch in your original ECU if you need to get smogged. Check out the N/A library under Engine Management.

Nice thanks again, would you think my setup listed would pass smog with the OEM OBD-II ECU asuming there are no problems with the car?

i say go with hondata. an s200 is more than you need, really. crome works good too.

hondata is of course only obdI compatible.

i'd also suggest investing in a better header/exhaust.

i thought if you swap in the jdm h22 you have to convert to obd1?

dont you have to switch to obd1 with chrome also?

Nope, you can swap some key parts to be OBD-II compliant.

Also if I went to an EM I would swap to OBD-I and a standalone and then swap the OEM ECU back for smog checks.
