well my name is Cesar and im in progress of buying a crx and was really thinking about dropping an h22a1 in it but dont know what i am fully going to need. What i know is that i am going to need a custom wiring harness axles from a 90-93 integra i think, custom motor mounts,...which ecu do i use and what OBD ecu .....anything else??? thanks for your help

 

great write-up

but you have the choice of using the Prelude transmission or H2B using a B series transmission

 

nice and thanks for info....probably use prelude tranny...better gear ratios right??

 

that URL really helped...gave me a good summary of what i need to do thanks blucivic

 

no problem

from what i've read, which i would still recommed you do your own research, the b series transmission is better than the H22 transmission and that the H22 transmission is the bulk of the weight for the swap and if you ever have problems with it, it's harder to find a good used H22 transmission than a B series transmission...also, if you do get an H22 transmission, get the one with factory LSD...on the flip side, the H2B kit adds a substancial amount to the swap and you have to do some shaving to the engine block to get it to fit...pernally, if i were to do the swap i'd use the H22 transmission, that's just my opnion

 

I went h2b. More work involved but more rewarding in the end.

BLU Civic were you a member on Automotive Forums? Your name looks familiar

 

You use the stock harness from your car and add to it. You can either use a p13 ecu or do like I did and use a chipped p28. Axles depends on h22 or h2b. H2B you use integra axles, h22 you have to have one of them made (esp has the info the axle). Esp and hasport sell h22 swap mounts for ef's. For h2b you use b series mounts.

 

thanks for the info...so obd1 would be good right and i think i will use the ecu from a U.S 92-95 prelude si vtec...will there be major electrical or wiring involved with my option.

 

i'm everywhere lol...been a member there since '03

 

I knew I had seen that name around. No matter the ecu you will need to convert to obd1. If you use a h22 ecu you will need to wire iabs and the egr also.

 

i did it in my crx. i dont really recommend it. if i could do everything over again i would do b-series. its to much work to put everything back to original. its a pretty sweet and unique swap but i think there is more power potential with a b-series. you cant slam your car either with the h-swap. my car just cant go low enough with out damaging oil pan and header severely. the h-swap involves some custom work to. you have to weld in a new mount, cut out your stock shifter location and bolt or weld up the prelude shifter box. so thats just my 2 cents from first hand expierience

 

A stock H series compares to a mild built b series. I will never go b series. If you go with a h2b there is nothing that is changed you use be series mounts. Therefore if you want to go back to a different motor for some reason you can.
