    OBD2A P75 Manual ECU. I don't like chipped ECU's unless it's a built motor that actually NeeDs to be tuned. OEM FTW.

    Use your existing engine wiring harness.

    Not sure on EK's but EG Civics need a B18B Intake manifold to shut the hood.

    Google is your good friend.

    Thank you so much for replying,
    So the wiring harness from the D16 works?? That was the previous engine
    And what about the axles, the b18 is kind of similar, can I get the ones from an Integra ls??
    This is my project car and I really dont wanna screw it up,

    yup, you can use the ls axels (frankly, any integra except type r)
    most of the d16 harness will plug right in. might need to extend a few wires to reach, but thats about it.

    Ill Check Out those pages for sure!
    right now i just wanna get the car running since its gonna be my daily, but i also wanted to see what would be the best way to tune it, is it better to build the bottom with a b18 head, or do i go B16 head and a medium turbo.. I do not know yet but once the Car its running, my budget will be about 3 grand..

    b16a and b18c1 heads are very similar in power output for the most part for a basic setup. gsr will offer a little more mid range, where as the b16 will have slightly more top end at the VERY top.

    the turbo on either will destory the all motor of either, so it's not a comparable metric really.

    look up Majestic Honda. They are a dealership that does a ton of OEM parts online at good prices.

    I searched eBay for a OBD2A P75 5-Speed..... No dice as of yesterday. A ton of auto trans ECU's though.

    But a OBD1 will work with a conversion/jumper harness.

    But you'll need to take emissions into consideration, and by the time you get the harness, it ends up costing twice as much. just wait it out, post a wanted ad here and on other honda forums.

    I have a obd2a p75 if you still need one.

    Also the driver motor mount bracket on the block wont work. It will put your motor about 2-3" low on that side.

    Are you using a jdm or usdm motor? If using a jdm one you will need to bypass the crank sensor for the car.

    You need a LS or aftermarket intake manifold.

    If you want text me at 479-453-6094. I just did a b20 swap into a 96 Integra a couple weeks ago.

    Even with a mount kit yeah you will need the right block side bracket. Did you get 2 post or 3 post mounts? I just sold the 2 post mount I had. I may have a extra 3 post though.

    You have to use teg, delsol b series, or em1 axles. I'm 95% sure the crv ones are diff.

    I have a stock ls intake mani if you need one of those.
