guys i bought H22 JDM engine, it's only a engine. could you tell me what other parts would i need to swap this engine in civic. which would be better use civic transmission or i should change transmission too? thank you very much

 

The D-series transmission that's already in the civic won't bolt up to an H series motor unless you get an H/F to D adapter plate (which I'm not even sure are on public market yet?) - Since that plate is 1k extra, I'd just leave the regular H trans on it.

With that said, go to hasport or avid, buy the H22 to EG or EK (whatever you have), and then it's pretty damn plug 'n play. You have to wire up a resistor box so the injectors are in check (not too many wires, pretty easy), wire up the IAB's, and some other small wiring ****, but it's no harder than a GSR swap IMO besides the resistor box (which is like a 3 hour project if you've never done it before).

H22 swaps used to be full fab - now they're full plug 'n play thanks to companies like hasport and avid.

EDIT:
PS: That trans is gonna cost you a pretty penny.

A D series or B series won't plug onto that. The cheapest you're probably gonna get your hands on an H2B adapter plate is about 7 or 800 - not including the transmission itself (which for a B series transmission is like 700 bucks). On the flipside, I'm not sure if the H2D is even marketed yet or it's still in testing stages.

So I'd go with the H22 transmission, but even that's expensive, a less expensive option might be the F22 or F23 transmissions, they'll cost less, but they're longer..so your acceleration might not be as great..they'll bolt right up to the H22 with the same mounts 'n all. ****, even an H23 trans would be cheaper.

 

If you have the motor then you would need: motor mounts, tranny, wire harness, ECU, Prelude shift linkage, and Prelude axcles to complete the swap.

All kinds of info there, incuding various H22A swap topics.

 

H2bs your best bet in terms of difficulty

 

prelude axles wont work, you can use the prelude intermediate shaft, but u have to use integra outers, also you can use the accord shift linkage which is a whole lot easier to find

 

If you feel like getting custom....f series trans out of the old school cb7 accord's bolt up to the h series

 

get an h22 tranny

spend the money

do it right

 

The original h22 tranny kills gas on the freeway like the b16.

yeah or you could hinder performance by using the transmission out of a granny car

 

the shortest geared h22 tranny is still much taller than any b16 tranny....
