need help i wanna put a 1.8 gt twin cam into my 1.6 single cam car is this possible. do i need to change the wireing looms or r they just a perfect swap. thanx aj

the ecu's look the same and the pins are the same just wonderin would i be able to take the 1.6 out and put the 1.8 in. thanx aj

The ECUs will definately be different

THe wiring between the ECU adn the engine maybe the same, but it is easy to swap

If it was me doing this i'd swap the engine, ECU, the wiring between both of them

And also check your Fusebox under the Engine bay as some of them may be rated diffrerently

crack on an do it bud!
be the best thing you can do

i did a engine swap (GT to GT) in 20hours flat!

swap can be done easily, you'll need the engine itself and the ecu with the engine wiring loom.

gearbox and all sorts can be kept the 1.6 stuff. mind you, to fit the gearbox on the 1.8 you'll need to swap your flywheel of the 1.6 as well.

i got the hole 1.6 car and the 18 so got every thing i need. just dont wanna strip the hole car to swap the looms. lol.

not nessacary at all. only the engine loom, wich connects to the ECU and 2 other connectors underneath it. If you follow that loom and get it off the firewall you'll see that it is a peace of cake

did the 1.6 to the 1.8 conversion but didnt get the engine harness so im using the 1.6 brain plus the 1.6 injectors.I AM NOT GETTING THE 1.8 FEEL. Can anyone advise me?

I don't know which 1.6 version You have but I'm guesing that 1.6 16V from BG.
You need BP ECU, without this You don't have control over VICS (ther was no such thing in 1.6). Between 1.6 16V and 1.8 DOHC there is only one wire difference in the engine wiring loom (metioned before VICS).
Change injectors to the ones from 1.8 because now You can have very poor AFR and kill the motor.
Also what kind of TB You have 1.6 or 1.8?
