CB7 V6 Swap Parts List & Methods

[zack_odom]

Find a complete J32 and 6-speed then get back to us.......

Availability of the 6-speed is just about 0 right now. You either have to know people or be very lucky to find one.

It's very do-able, just not very easy to source the right parts now.

Sure, someone could do it right now with an auto-trans, but that would hardly seem worth the effort.

Somehow I completley missed that the 6 speed was the only tranny (Auto ftl)
That would work lol...Srry.

i built a v6 accord 2 weeks ago but sold it..

Not the only transmission, just the only one worth using on this swap. Look at it this way, if you are going to be putting as much time and effort into the swap as it needs to be done right, then it would seem foolish to use one of the Automatic transmissions.

Saaaa-weeeeeet!!!!! Probably has some ungodly turbo setup or doing something with the Competech kit I bet.

Although I highly doubt it's for a CB application, this is great news because it means that Mike is going to learn exact what is needed in terms of wiring and connectors for the J32. I'm sure there are slight differences between that and the J30, but I'm sure they wouldn't be any problem for you to figure out.

I know you're busy, but let us know how progress goes on that build. What is the project car?

You are more likely to find generational differences than model differences IMO.

This I don't completely agree with.

Yes, the auto would be heavier, and the 6 speed would probably be preferrable in most cases, but a STOCK J30 auto 4 door accord will out run an H22 swapped Accord. I know because I have both. It doesn't pull much, but it does pull until about 90MPH, where they are about even until 115. And that is with H22 gearing, and extra weight in the V6.

At 3400lbs they will do that, so imagine what they would do in a car with 400 fewer pounds, and about 40WHP worth of bolt on mods...

And you don't have to dick with it in traffic. Also, the fact that they are 5 speeds makes them equivalent to anything in CB7 as it is.

Also, depending on which year, there actually seem to be some gearing and other differences.

For instance. The 2006-2007 has a lower first gear which makes it feel stronger off the line, but it has a larger hole between 50-60MPH where it won't downshift. The tranny hooked to the J30A4 on the other hand is a little bit less aggressive in 1st, but seems to have better gear spacing in some spots. Also, the 2006-2007 shift programming is more aggressive. If you get on them, they really bang the gears pretty good, whereas the older 03-05 trannies seem to be programmed further toward a softer shift.

Also, personally, I would try and score a J30A5 if you go that route, because I swear our 06 is stronger all around than our 04.

Not saying it is the IDEAL solution, but for the price difference, I bet the end performance difference wouldn't be as huge as everyone assumes.

That's what it boils down to. Finding a 6-speed is going to be very difficult. It's also going to almost double the cost of the engine/tranny combo unless you can find some killer deal.

Point taken.

Are the automatics controlled by any insane computers?
(crazier than what is already on an auto accord?)

Well..........

Our CB's use a TCU to control the Auto transmission. Manual CB's don't have this, so there isn't any control wiring to it.

The J-series automatic transmissions use an ECM/TCM combo unit that does everything. I'm sure there are different flavors depending on engine/transmission/year/ect. but there are still control feeds off of the transmission either way (just more with the auto).

I don't think it would be too hard to figure it out, but it would just be something else to deal with.

[chessboxer]

Currently, the initial vehicle wants to keep his auto with his setup.

What we plan on doing is what we call a parallel piggyback setup. YOu use a jumper harness to connect to the stock wiring harness and leave the stock ecu and tcu plugged in.

You take away the injector and ignition controls from the ecu, and you intercept all the important sensors into the E11v2 ecu. The stock ecu stays to control the auto trans, but all important engine functions are controlled by our ecu, or so we plan to do it this way.

We will end up going with a custom crank wheel and a custom sensor to get our trigger, but apart from that things look good, although still some time away.

Basically a super advance VAFC, if you will. Sounds like a pretty smart move, and definitely saves you all some serious time/frustrations.

I may be just talking non-sense, but will the custom sensor you all use in any way change the way the stock ecu sees what's going on with the position of the crank wheel, or will all of the things that vary based on this be controlled via the E11v2?

[chessboxer]

Stock ecu would see the stock crank sensor, as it would still need to know rpm for the trans.

We will fully take over the control of everything else, and this just allows a stock ecu to remain and control certain functions. Our 350z platinum ecu does this, as the stock ecu remains to control the dash in those cars.

Another more realistic/cheaper alternative

5 spd tranny/linkage/hydraulics from 1st gen Legend

2nd gen Legend motor (preferably Type-II) w/1st gen header

Mounts yadda yadda

Harness/ECU swap from 2nd gen chassis

Custom axles/mounts

V6 CB, for the same amount of work, and everything prob for the cost of a J-series 6 speed tranny, new

And exploding head gaskets, less power, more weight...

[Tnwagn]

C-Series?

I hope you are joking. Not worth the trouble unless you somehow managed to find/finagle in a C32B, but good luck with that.

Cheaper, sure, but it would take the same amount of work and it wouldn't really be an upgrade in terms of technology. I'd equate that more to a step above the H-swap.

Don't know if this was already mentioned as I only read the first 6 pages and the last 2 pages but, check this out.

If a Corvette motor can be put in a Civic and the Civic made rear wheel drive, it should not be hard at all to put a J series in a CB7. Good luck with your build. I will be watching this thread carefully

[rexload]

I would like to see this swap happen and pictures of the process etc.
Is anyone actually planning on giving this a try in the near future??? This is very interesting!
