CB7 V6 Swap Parts List & Methods

[Tnwagn]

I think some of your facts are wrong.

The Hybrid didn't use VCM, and I am almost 100% sure of that. Also, any J series introduced AFTER the Accord FMC for 2003 has the 1 piece integrated manifolds.

Great, thanks for pointing that out. I'll update the info. I'm not 100% sure on any of that information in the table, it's just what I could find online.

EDIT: Engine info update with owequitit's info

Tnwagn you are the man!

Any idea where I can source the CB7 diagram? I lost my haynes manual.

I just have to send this to Rywire and Ryan will put together a harness; he said it will cost around 100USD. Chump change. :P

And for anyone who is feeling truly ambitious, here is part 1 of the ECM/PCM wiring. I'm not going to actually post the full thing here as it is too big, so I'll include a thumbnail and a link to the actual full size one.

Your kidding right?
Get me the CB7 and V6 harnesses together and I can make 1+1 work

Just FORGET tuning....its a V6. way more power than you ever can use
Just use the stock harnesses and ECU, then maybe wait for someone to unlock the ECU.
About 90% of these civic swaps are stock too. They still burn rubber in second gear.

Also VCM isnt the engine its the computer.
VCM controls aspects of i-VTEC namely the release to cam lobes....
An ECU without VCM would opperate the engine just the same minus...you guessed it VCM!

It also too bad that the VCM mechanism replaces the hi-performance cam lobes with the ability to shut down cylinders. So, you wouldn't have any VTEC.

You obviously have no idea how VCM works...

I will post up ECM/PCM diagram Part 2 and the Accord Diagram sometime soon (tonight maybe, tomorrow maybe, this week maybe...)

And yeah, 100$ is definitely worth it if it's coming from Ryan, his work is solid. We could all probably do the wiring harness, but if he can do it for that price then I'd rather leave it to the professionals.

The VCM equipped engines are only in VCM equipped cars and have their own special block code. There are many mechanical aspects to the VCM system that can't be done in blocks of code in a computer.

I'm not 100% sure how much any of this will match up with any other J-series engines and their ECM/PCM's so I'd recommend you know exactly what you are getting before you dive too deep into wiring.

EDIT: So all of the plugs wouldn't fit all in one image (too big to upload) so there are two images here to represent all the plugs.


I'll put up the last large ECM/PCM diagram up tomorrow sometime

Now that I'm all rested up and awake I realize I have a number of questions for you about this post

1. You ask where you can source the CB7 diagram from. I have it and will put it up for you, but why would you need it to do this swap?

It's not like we are going to be tying into almost any of the CB7's wiring as 99% of it is incompatible. If you are wanting it to see about cluster wiring (which is what I'm guessing you need it for) then I'll go ahead and say that I am fairly certain that there is NO way this motor/ECM is going to work with our stock CB7 cluster. There are too many differences in the signals being transmitted and the sensors used on the engine. It would be far simpler to use a cluster from a J-series equipped car, or to use a custom display option such as a RacePak.

2. You say that Ryan will be able to make you a harness for about $100. What kind of harness are we talking out here? Is it going to have all the ECM connectors AS WELL AS the wires to all the sensors and plugs on the engine?

Immobilizer System Wiring

Great thread and SHITSLOADS of info. I probably already posted it earlier in this thread, but it's worth a second posting

http://www.v6performance.net/forums/...t=54261&page=1

Oh yeah, J35A5 is out of question unless you want it to stay auto-tragic

J35A3 on the other hand, can accept the 6 speed

Has anyone compiled a list of the major setbacks holding this swap back?
1- Mechanically, it doesn't seem too impossible.. sure some custom fabrication but nothing out of this world
2- Electrically it looks like there's going to be a somewhat bigger challenge (Probably the only real barrier)
3- Will it be an issue getting it smogged? For us California guys too?

I've read the thread already but think it would be helpful to make a master list in one post. Things like custom axles, mounts, bypassing the immobilizer, drive by wire issue, etc. etc. etc.

Let's try and get this swap into perspective. Is it really possible or is it just a dream?

Any links to J's in other Hondas? Civics? Preludes? (Yes I've tried Google)

I just dont know why I've been following this thread for almost two years now and haven't seen any development.

[Flatline]

Maybe we are looking at that CB7Tuner site car someone was talking about a while ago.... good way to get the CB7Tuner name out there.


It would be magazine material if this actually got done. I say we start a donation thread to Deev who could start an account for it. I would donate at least 20 bucks a month to that. and with say.... even 10 people per month, that would be 2400 bucks BEFORE interest towards it. it might be a while off but i would definitely be up for donating and even stopping by where ever (assuming its kinda close) and lending a hand


I say shoot for it. and maybe like a small donation some of the traditional classifieds sellers can agree to per transaction or something kinda like at a direct auction how the auction house gets a percentage.



Where there's a will there's a way right?

A 2003 Odyssey came into work today and I asked the lead tech if he thought it was possible to put the J series v6 into a CB7 and he thought it could be. His suggestion was to find a way to bolt the subframe of the donor car to that of the receiving one.

This is going to make or break the CB7 for me. It's either v6 or sell it. I'm willing to invest the money and time, I just don't know enough to do it myself. What are the major obstacles holding everyone back??

engine mounts, wiring harness, custom exhaust mid pipe.

lol I shoud throw a v6 in the cb7 now that the a6 is dead. Anybody wanna wire it up for me?

Do you guys think you'd even be able to line up the axles with the wheels? And still fit the engine?
