-To get the D15B to work, you would need to convert your car over to MPFI and to OBD-1 using the Rywire conversion harness.

-You will need the manual P08 or manual P28 ECU to run your car.

-You will need pigtails to plug into the VTEC solenoid on the D15B to get VTEC to work. You will then need to wire in VTEC to the conversion harness. You will also need to wire in a 4-wire O2 sensor (From a 92-95 Civic EX/Si)

-You can use the 4 spd. transmission on any of those motors, it will bolt up. The best one to use is an EX/Si transmission, which I PM'd you about.

-You will need to take the driver's side mount off of your D15B1 motor to replace the mount on the D15B.

To make the SOHC ZC work in your car...

-You will need to convert to MPFI using this conversion from Rywire and a manual PM6 ECU.

-Your transmission will bolt up and work, as well as any other 88-91 Civic transmission. But, as stated earlier, the EX/Si is the best.

To make the DOHC ZC work, PM budget_crx, he has a lot of experience with this swap.

I would just use a cable transmission and save money instead of converting to a hydro transmission. Like I said before, get the 5 spd. Its an easy swap.

PM me if you have anymore questions.

can conferm i have that same set up in my 89 hatch and i have the si tranny and it is a blast to drive the cool part is the high revs that that motor will take i have done pretty close to 90mph in second befor i had to shift there was no reason for it i just did it lol

Heh, in the top tab of the lil bars where people text is, is this thing called thread tools, click that, and hit suscribe. Then when you get home, you go to your suscribed threads in the usercp! Just for future reference!

And the funny thing is, I just came back to this site to sell my '90 hatch after a few months, and my thread has the most recent post in the forum...
Irony?

Shouldn't be too hard.
Someone had offered me what I want for it when I first joined the site, but he's inactive now.
In the meantime there's no harm in putting the car FS in my sig, right?

Nooo, I think he is saying that it isn't against the rules, as far as he knows...

Idk, I just want to get rid of the car quick so I can buy me a Mazda MX-6. =]
