I have a 4 cylinder automatic 2000 Honda Accord, I'm thinking about doing a J32A2 engine swap. I know how to do some simple stuff like bolt-ons and suspension and brakes. But I think this job I had to pay someone professional to do it. For the people who have done it, how much did it cost in hardware (engine, transmission, ECU, engine mounts, and all other necessary hardware) and labor? I'm thinking maybe $5-6k for this, is this realistic or am I underestimating the cost? Thanks.
You have the wrong platform to start with. Some of the accessories are on the opposite side on your 4 cylinder model versus the V6 model. Going from a 4 cylinder to V6 is TONS of work.
You would at least need to change the following, if not more....
Front Subframe
All front suspension components
Fuse box? not sure if the electrical is the same
also, there is another small electrical box beside the big fuse box. I don't know what that is but it's on the V6 model so you may need that.
ABS module - if you want ABS, you will need to fabricate new ABS lines as well as swap the rear I4 Drum brakes to Disc
Radiator itself; the hose outlets are in different areas on each radiator & Overfill tube is routed opposite way.
Cruise control module - if you want this yes you need to relocate this component, but you could go without this one.
V6 CV Axles
Air Box/Intake : not sure if this would mount up on the I4 engine bay. There may not be any mounting holes in the spots you need. The mounting holes you need may need to be made and a holes cut into metal to route the air intake tubing.
Brake booster and reservoir seem to be in the same spot, so you may be lucky here. But, I don't know if they are the same part? but you got the V6 donor.
You may need the splash guard from the V6 car too> not sure if this is the same or if it would mount up. Again you may need to make your own mounting holes?
You will need the V6 cluster, as the water temp sender in the cluster?(not sure on this term) is different versus the I4 cluster.
Gear shift.
There is a reverse gear lockout feature in the shifter, the wiring may or may not be the same in each car. Wiring issue may pop up on this one.
You will need to have the I4 key re-coded by a Honda dealer to match the immobilizer chip in the V6 ECU.
