03 Accord 2.4 engine swap to 3.0?
Is it possible to swap out my 2.4L Motor to the V6 3.0 motor? I have a 2003 Accord EX, 5spd. The engine in the car now just hit 200K miles. The car it self has brand new tires, Suspension, and ball joints. I was planning on upgrading the tranny to 6 Speed as well. I do not have enough money to buy a new car, but I do have friends that work at a junk yard that can get me the new engine and tranny for cheaper then list price. I was just wondering if it will fit and what else I would have to upgrade to get it to work properly. I have experience rebuilding motors and trannys. I just don't know much about how the motor mounts and how Honda computers work.

By far the easiest/cheapest thing you can do would be to find a used four cylinder engine from another car and put that in; doing so will save you literally thousands of dollars and hundreds of hours of work. |
I second that motion.
Would require way more custom fabrication and headaches than it would be worth. |
For 2003+ there's less work because the 4-cyl & V6 engines are on the same side of the engine bay.
That was a huge problem for 1998-2002 cars because EVERYTHING ELSE in the engine bay was different. Battery, PS hoses, fuel lines, air-cleaner, ABS modulator, even the windshield-washer reservoir were all swapped over to the opposite side & they were different parts. Still, I think a ton of stuff that you don't expect would still have to be changed over. It's still a bigger job than just "swap the engine". |

LOL...
Not sure this is reliable, but I've heard their first automobile engines spin the "opposite" direction because traditionally the motorcycle engines spin that way. The direction the engine spins determines which direction it's mounted in the engine bay. When they designed the J-series V-6 they go with the opposite direction because by that time they were an established car maker. The same thing in 2003 when they introduce the K-series 4-cyl engine. |
Ahhh, so that means that the 4-Cylinder engines are now all mounted on the right side of the car with the transmission to the left; same as the V6, and the same as every other maker of transverse FWD cars. Works for me. :)

Yup.
The Civic swapped over a couple years later, maybe 2006, with the introduction of it's R-series engine. I don't know how that worked out with the Fit, Insight, CRV, others?? |
Be cheaper to sell your car and buy a 7th gen with a V6 than to swap motors.
|
Find a blown up V6 car for cheap and get your junk yard motor. Sell your barely broken in 4cyl
