AGZE wiring question

[espguitarist33]

Hello,
So I have a 1985 mr2. I'm looking to swap in a 4agze, since the swap ends up cheaper then just replacing the 4age engine.
I pretty much have seen the mechanical done, all of the problems and stuff, well showing its simple. My question is. If I get a JDM AGZE swap, with Motor
Transmission
ECU
Wiring Harness
Supercharger
Power Steering Pump
AC compressor
Alternator
Starter
Intake Manifold
Turbo Manifold
Coilpack
Ignitor Chip (available)
MAFS (available)



since it has a wiring harness and ecu, would it really need wiring work done? wouldnt the chassis harness be plug and play with this ecu? the only changes made were in the engine of the car right?

i've been looking for info on this since spring and am having bum luck :/

if you get a 4agze with a distributor and a normal oil filled coil it's almost a plug and play but the fuel injector resister (the 4agze has it in the engine harness and the n/a car has it in the chassis harness)and fuel pump(was a one jump at the fuse box in the engine bay) and starter( i was doing a push button so i did not get into to the ze harness as i tried to keep the two harness separate from each other) if you wont more detail let me know i did the swap last summer and went to a turbo at the begging of this summer now building a hi comp turbo out of it

I definatly would like more information!

I threw a rod on my car (long oiless story fml). But aparently we found

Jdm Corolla MR2 Blktop 20V 4AGE Engine 1.6 DOHC:eBay Motors (item 130326750935 end time Sep-02-09 19:15:09 PDT)

cheaper....are these just plug and play in an 85? i dont really care about the power especially if this engine could handle a small turbo later on or something?

i dont know much about the swap to a 20v but that one does not give any info so you might wont to check to see if it comes with all the parts it ses no manifold so that means no map and if it does not come with a map i dought it comes with a ecu and that makes it useless and if your going the blk20v you should go all the way and get it with the 6 speed and swap every thing

[espguitarist33]

of course...never easy. Do you know what engines drop in directly off hand? that might be best to start out witch, see if i can find them and save some cash over a full gze swap

[donnyavery]

other then a ze swap the easiest would the stock 4age (that i know of but i could be wrong)

[espguitarist33]

Thats what I mean..will the 2(?) rib 4age's (the newer reinforced ones) wire up directly?

[espguitarist33]

7rib?

[donnyavery]

yes as long as there na with oil filled coil

[espguitarist33]

I'm still really intrested in a silver top swap though. I read blacktops arent as good for aftermarket and turbos and stuff depending on how i feel down the road.
To anybody who has done one...I'm still fuzzy on how the whole ecu thing will work. does the harness get adapted to the mr2 ecu? does the mr2 harness get adapted to the new ecu? since i'm in stupid PA...i gotta worry about codes...what diagnostic does the 91-95 donor car use? will it throw codes?

sorry to ask so many questions

[donnyavery]

all ways to the new ecu the ecu for the motor your putting in is the ecu you have to use because some are maped diff and or some use different sensors
