1990 Honda CRX Si D15Z1/HF Trans Swap Project

Depending on the state of your OBD system attaching the shift light to the CEL might be a good call (especially if you will have a permanent CEL after the swap).

I really like what you did with the valve cover; it looks very clean. I was just scrubbing and cleaning mine the other day and thought about how I could keep it cleaner. I have always liked the aluminum on black look. Keep it up on the swap; it sounds like you are doing it right.

Thats been my only idea for the shift light thus far.. Maybe wire it inline with a 2-way switch and turn it off if I don't like it.. That way the option could always be there..

And Thanks for the kind words hawk.. I've got a reciept book for this car that is pretty much made up of a 3-ring binder and document protectors to show the work Ive put in this car.. That way, if the car ever got too old or I just wanted something else that maybe I could justify my price if I ever decided to sell it.

The only drawback to doing this much work on a car is always wanting to do more... lol. Since Ive been junkyarding pretty hardcore lately Ive been seeing 4-door sedans with cruise control and power locks and windows... This is all just an idea for now but I figure if this thing is gonna go slow that I might as well have some luxuries.. haha.

And Im already planning a trip on it to Louisiana hopefully later this summer. Ive got a good Army buddy out that way who recently had a baby and it would just be a good reason to see what I can do with the car in 2,000mile trip...

So much to do and so little time... Thats always the case..

Really beautiful! I've always wanted a D15Z CRX.

The power locks and windows are quite doable, and not even that difficult. (Unless you want to try to find the OEM JDM parts, yo, because those are quite spendy!)

The cruise control for the Civic EX doesn't quite fit the CRX. The electric motor for the vent selection buttons gets in the way. If you switch over to the cable-operated system the Civic uses, then the Civic's CC fits just fine.

There are aftermarket CC setups that will work pretty well in a CRX as well.

If I'm not making things up, I think the former owner of the gassavers forum, Matt Timion, did a VX swap into a 4-door Civic body.

I have a feeling he never quite got it quite finished before just giving up and buying a Fit though!

If I wind up doing this it will definately come from the junkyard. I go about once a week now, rotating between junkyards..Thats the downside to buying an incomplete shell. I will say though, if I ever come across a complete JDM frontend on the cheap, I will definately roll with that for aesthetic purposes.
For anyone who reads this thread please know that buying a complete car is always gonna be better than buying a shell unless you can come up with a whole parts car for the shell.... Ive got so much time and money in this car even before the engine that I'd pay $2500 for a clean CRX with a blown engine or trans or whatever.. The small stuff really adds up..

Thats a shame. If I can come up with a four door or a wagon, Ill totally do something similar with all the spare parts Ive accumulated.. Kinda wish there was more guys interested in this kind of a swap around here. Everyone around here wants to go fast in Hondas.. That just means more lean burn parts for me!! lol..

According to the Chiltons manual , while wiring, The leads on the L1H1 weren't lining up with what is supposed to go back to the ecu...

So now I get to scavenge the web for info on this thing and make sure Ive got it wired up right..

So far there has been alot of misinformation floating about the WWW and Ive had to repin my conversion harness because of some misleading information.

On another note, I do have the car lowered all the way around now and am looking forward to cranking this thing soon!!

[02ws6]

This is what Ive gathered so far.. Please let me know what you guys think on the 02 wiring.

Ive got a stock VX wiring harness that the sensor plugs into but according to Chiltons and Helms my stock sensor or wiring harness is wrong..

I have the NGT sensor with the following wires:

Red
White
Yellow
Black
Orange

I am gonna wire them accordingly:


Yellow: Heater Ground (-) to pin D3 ? (Not so sure about that one.. but its all thats left from the diagram)

Orange: Heater Power (+) to Pin A6

Black: Common Ground ( for IP and Vs ) to Pin D16

White: IP circuit (Current pumping) (+) to Pin D14

Red: Vs reference (+) to Pin D8

Door locks are really cheap off of amazon. Just look for the actuators. I think I picked mine up for less 5$
Amazon.com: HIGH POWER DOOR LOCK ACTUATOR 2 WIRE: Automotive

OR
For windows and locks.
Amazon.com: Universal Power Window Kit Plus 2 Door Lock Kit with 3 Switches: Automotive

I actually picked these up for my 89 Si and were a breeze installing.

Sweet work man. I've always liked the crx. But I have a 70lb dog and he can't fit in the back. If I could cheaply alter the roof line to be a little taller I'd buy the hell out of one and do the 15z1 swap any day!
Also, if it was me I'd stick with the non powered goodies. Crank windows don't bother me at all, plus I use less alternator and the older style motors for the windows would prob weigh more. Newer cars maybe not...
