I have a 7th gen Civic coupe shell sitting around that has some sentimental value to me
So I started toying with the idea of putting a J-series into it


I'm just trying to get an idea of what issues I may run into
Obviously I need a complete J-series engine with all sensors.. flywheel/clutch and a J-series manual transmission


Once I have the engine and transmission bolted together, I can drop it into the engine bay
Then adjust the height so that the hood closes and clears the motor by 1/4" or so (this way it won't be sitting too low)
Then eye-ball the motor so that it is in the center of engine bay and parallel to the steering rack
Then fab the engine mounts


Then I need inner pieces from some J axles + outer pieces from my 7th gen Civic axles
Measure what length center shafts I need for my axles, then order custom center shafts


Then I need to address things like
-radiator/cooling system - install custom hoses where necessary
-exhaust - weld/fab custom exhaust
-fuel system - use the stock 7th gen Civic fuel system?
-clutch slave cylinder - needs to come from a V6 accord?
-throttle body cable - custom
-ECU/immobilizer/key - needs to come from a V6 accord?


Then comes the wiring. I guess I would need a J-series engine harness.
Then just follow every wire from every sensor on the motor and make sure it leads to the correct ECU pin


After all that is done, I would be able to put the tranny in neutral and start the motor



Some other items to worry about would be
-what shifter/cables - from a v6 accord?
-what gauge cluster - from a v6 accord?


I am just trying to get advice or some pointers on what I am missing ?
Any other problems I might run into?
I wanna have a solid plan before I start buying any parts for this swap

Wow no replies 😂

these kids are only god at 4 cylinder swaps. They’re scared of the big v6’s 😂

No updates from the OP either... looks like this project was dead on arrival. This would have been an incredibly difficult swap... unique, but very challenging. The OP even suggested this. I think he took his own advice and changed his mind.
You seemed a bit snarky in your reply... are you a four cylinder hater and a V6 fanboy ?

I LOVE Honda engines no matter the size. I’ve owned 4 cylinders and 6. I am snarky because some people are quick to shut down people’s ideas because “it won’t work” or they think they should “just go with a k series motor” lol

i have acquired a 2001 civic and the motor was bad when I bought it so I am trying to decide what route to go. Either put the original back in it and sell it and find something else, put a k series in it. Or shoot for the fences and put a J35 (with a J32 head) and the 6 speed with LSD.

ive always wanted to do a V6 swap in a civic and I think it would be hard to do but very satisfying when it’s finished.

what are your thoughts?

The "K" series engine family has a ton more support and is a much easier swap in a 7G chassis... but there is nothing wrong with being different. You are going to have to fabricate everything for a V6 swap into a 7G chassis, and if you have the skills to do so, swing for the fences man. I think you can get similar power with a "K" or a "J"... so do you want to be different and difficult or simple and more common... if you can say common with respect to 7G swap cars. Since the chassis is heavy and has a much smaller engine bay, people tend to choose the EG or EK chassis for their lighter weight and larger engine bay... not to mention more products/support to choose from.

well that’s good to know cause I have a 1997 civic sedan that I was debating putting the J swap in also.

so maybe I’ll sell the 2001 and just stick with my ‘97 civic engine swap 😬

Hey hey hey... now you're thinking.

Well well
I see this is an old topic
4 years ago I wanted put an j32a v6 in a civic 2005 es3 chassis. I have searched the whole internet high and low for ANY damn info. Till now I am searching but Nothing found.
Then I started to machinng the chassis to make it work.
Long story short, tree months later I started to enjoy my J swap 7th gen. But soon, the auto tranny failed. So I dicided to go manual. I start ordered anything i need for the manual swap.
Now, I ve been enjoying this setup for more than 3 years. To be honest,
The chassis doesn't take to much adjustments. Space is thought but I love this swap, especially with a 6 speed from the v6 accord.
It is incredible fast and a lot of other brand v6 can't beat me on the street.
That beeing said, everything is possible!
As long as you believe!
