Engine swap question.

Postby Morgan86 » Sat Sep 19, 2015 10:12 am

I have done some digging and have found most of the info I need, and I'm about to put a parts list together. I just have a few questions about my particular swap
(I'm a noob, with modern engine swaps ive only done old v8s)
I have a n/a aw11 high comp red top.
Do I need to get a engine harness specifically for the mr2 or will any 4age harness work?
How about lights?
Is the rear harness just got the fuel pump? If so has any one made there own?
What harness uses the rear wiper (i want to run in street modified in scca they state I need wipers) .
Will I need a different dash harness for red top?
Will I need to make any adjustments for a ma46 (i think) celica supra or gts rear end swap?
Lastly Does anyone know the easiest way to do find all these looms!? [emoji12]

Thanks for any info.

Just to clarify... nit picking aside, there are basically two types of 16V 4AGE
engine. The earlier TVIS "bigport" engines with 8 inlet runners and the inlet ports
arranged in two pairs with more space between cylinders 2 and 3 than between
cylinders 1 and 2 or 3 and 4. Then there are the later non-TVIS "smallport" engines
with 4 intake runners that are evenly spaced.

The engines can be used in FWD or RWD configuration providing the correct
bolt-on accessories are used. That is to say, the longblock is the same. For a
RWD installation you would be best to start with a RWD GTS engine harness. A
small amount of modification may be required to match injector clips to injectors,
and to add or subtract some sensors.

You will need a GTS ECU if you want it to be plug and play.

The lights and wipers, ignition and EFI etc are part of the dash harness and it
should be easy enough to match up the GTS harness to the existing SR5 harness.
For the fuel pump you will need to hook up a circuit opening relay (COR) or make
something similar from two standard relays. Then install a GTS in-tank pump and
EFI rated fuel lines and run a wire to the pump from the COR.

The Technical FAQ should be able to help you out on the Celica rear end swap.
