i am kinda new at motor swaps so i need to know... i have a first gen eclipse with the 1.8 and i have a 2.0 out of another do i need to rewire my hole car to swap that or will the harness work for both

You'll need a new harness and ecu

The transaxle on a 1.8 is on the opposite side of the motor...so basically you need the whole front clip from the donor vehicle.

No, it's not....

But unless you are getting a 2.0L turbo. Then it's not worth it... It is actually cheaper and far easier to buy an Turbo model.
