Transmission – Automatic to Guide Conversion

When I bought my EG4 Civic hatchback in 1998, I beloved every thing about it, the physique inside and motor were all in excellent problem. On the other hand, there was 1 detail that I would not have picked out: the automated transmission. The primary motor was a JDM D15B SOHC VTEC, rated at a respectable a hundred thirty p.s. particularly for a 1500 cc!

So I started off my research on the web to discover out my selections with respect to finding the motor vehicle transformed to guide transmission. In my search, I learned Eric’s B16A web page and the Hybrid web page amongst others. So I commenced to believe, why go by the issues of altering the transmission on the 1500, may as effectively go for it an place in a DOHC 1600cc VTEC and gain 40 hp in the system! I thought of a B18C but individuals engines are exceptional and costly in Trinidad. In any case the JDM next technology B16A places out the identical horsepower, with a bit much less torque. From what I had acquired on the Online I understood the motor would healthy high-quality. Also because my motor vehicle initially came with a VTEC motor, I understood that the wiring would not be quite complicated.

I examine as much as I could discover on swaps, and tried to approach the operation to the greatest of my potential. Let me position out, that there is no substitute for excellent information, so if you are preparing any form of hybrid, examine as much as you can Prior to you commence internet internet sites, FAQs, posts, magazines, no matter what. I chose to have a area store with appreciable Honda knowledge do the work and I was in a position to find the motor from a area importer.

MY Miscalculation
I understood that it would be greatest to acquire the motor and extras as a deal, and which is just what I did. But I focussed on the large goods, Engine, Y21 LSD trany, Ecu, Total motor wire harness, axles, and in so performing, I did not even know that the motor did not have the mounts! (No AC device possibly!) Now while In my nation we have fairly a brisk trake in JDM areas, some things are pretty much impossible to get, like mounts!

The solution? Alter the primary D15B mounts to healthy. That blunder made a task that would have taken a very little much less than two months, very last five months. You could visualize how my wife beloved me for this!

Setting up UP
The mounts took a actually long time to total, furthermore as you would hope, my motor vehicle wasn’t the only 1 in the store! Anyway, it turns out that the rear (middle) motor mount could be utilized on the B16A. I was in a position to get a front transmission mount, leaving 3 mounts to be custom adjusted. By the way the lessen front motor mount / ac bracket on the B sequence motor is fully unique to the D sequence mounts so I fabricated an adapter flange to accept my previous AC device. (No way did I have intentions of purchasing an AC).

Just after the mounts were adjusted and the motor was in the correct put, the axle components was mounted in a jiffy, and required fluids and hoses were linked. All the electricals plugged appropriate in, which includes the new laptop or computer. The only change was the D sequence motor had the MAP sensor set on the Throttle Physique, so a remote device was added for the new motor. The motor fired up, no complications. By the way, you guys should hear what the beast seems like with only the tri-y headers! Given that the headers were more time than the primary, I had to modify the size of the exhaust pipe so that it could bolt to the headers


Now the Automatic Certain points. Get rid of the Automatic Equipment Lever and toss it! There is a plastic slider beneath which is linked to the car’s harness. This slider should be established to the PARK position and locked there by some suggests. The guys at the store place a large blob of silicone sealant around mine. This is required if you approach to take your vital out of the ignition after you generate!! Also on the plastic slider, there are two wires soldered close to the middle of the device (yel, blk/grn). When these wires are shorted they activate the reverse lights and chime. (At minimum my motor vehicle has a reverse chime). My suggestions is to discover the reverse sensor on the transmission, trace them to the link junction on the appropriate aspect of the motor bay, then run a pair of wires from the reverse sensor qualified prospects to the plastic slider. Voila! Your reverse lights will work high-quality.

I had to incorporate a knock sensor wire and an O2 sensor wire as thorough on the Hybrid Internet site. On the other hand, I even now got a code 23 after driving the motor vehicle for a couple minutes. Then it transpired to me, that the laptop or computer even now believed the motor vehicle was automated. Now, I actually tried to discover the Transmission Manage Module but for the life of me I could not. Perhaps you have to get rid of the sprint of a little something serious. Anyway, with the aid of a B16A2 wiring diagram from my mate Christian in Austria, I was in a position to detect the Ecu qualified prospects that were no more time desired. Just minimize the qualified prospects and tape’em up! The initially 4 are the TCM qualified prospects the other two go to AT sensors for which I will not have the German translation:-)

Ecu qualified prospects






Of system when you get rid of the automated gear shifter, there will be a gaping hole below there. I discovered that my motor vehicle did not have any mounting holes for the change linkage. This is excellent in a way, as you get to pick out the place the shifter will lie. I utilized a CRX shifter in my software and just bolted it on by the sheet metal in the floor arch. Relying on the linkage you use, and the plastic moldings that you pick out to place around the shifter, some adjustment of the linkage size could be required.

You will see a image of the pedal box from a CRX on the left. If you are actually observant you will detect that this pedal box is made for a cable clutch method. The verdict: scrap the thought of altering the pedal box. The guys minimize off the clutch pedal, and welded on a hinge so it could be utilized to actuate the plunger on the clutch learn cylinder. We utilized a comfortable line to connect the slave cylinder (on the trany) to the challenging line, which connects to the clutch learn cylinder. Very simple. In the inside image you can see the large (AT) brake pedal upcoming to the clutch.

THE Consequence
The motor vehicle works beautifully and is a pleasure to generate. Every single element and sensor is operational. Given that I retained the primary AT housing all over the shifter I did not free 1 of my preferred capabilities of the motor vehicle the fold in cup holder! The shifter boot is custom made from Italian leather-based. I also got the white confronted gauges with the offer!

I would actually advise from swapping in the other direction nevertheless because all the car’s wiring powering the firewall would have to be adjusted in order to get a completely useful (all capabilities working) automated.
