    Default 4AGE to 4AGZE Conversion?

    Hi there,

    New to the forums, did a search on the above - didn't find what I'm after.

    Is this conversion as easy as getting a manifold/SC unit/ECU/Intercooler/piping from a S/C model? Or is it a little more difficult than that?

    I've got the 1987 N/A model so I've got the C52 gearbox and 4AGZE block.

    What's involved in doing this conversion? Is it a good way to go or are there better ways?

    Thanks in advance,

    Sam

    you have a 87 N/A model of what??

    more specifics are better.

    but with the info you have given, it is much easier to get a complete running 4agze and then replace the 4age motor...instead of trying to build a SC out of a GE engine

    Yeah sorry I have an '87 N/A model (thought it was implied).

    So it's better to find a full 4A-GZE... why? Are they just a stronger motor (more than just the block) or is it because of lack of mounting points etc?

    I live in Alice Springs - little to no chance of finding a 4A-GZE motor around here, whilst it's potentially possible to send away for the bits to supercharge my motor.

    yeh 87 N/A WHAT????? lol

    corolla?

    it is better to find a already running 4agze, because it is REALLY REALLY easy....

    to build a 4agze out of a 4age becomes alot more time consuming and normally never gets done....

    have a search of this forum, and see how much infomation you can gather....

    there is STACKS of info out there.... but i think you will find you will be better off going the already running gze path

    thats cool man, i didnt know how to word it so it made sense myself haha

    ok now where talking...

    if you plan on running your c52 then you should bee fine with mating the 4agze up to it, if you plan on running the e51 then a Gbox mount will need changing to the supercharged model mount..

    but your question was more regarding the 4agze itself...

    if you have done some research you will understand why i recommended a already running package...even if you do need to get hte motor shipped to your place..

    to "build" a 4agze out of a 4age is not as easy as getting a sc12 and 'bolting' it on the side of the motor... alot more work has to go into it, that isnt worth the effort..

    of course this is imo....

    see if anyone else comes on here and gives you a different approach...

    oh and jump over to AW11 owners anonymous and post some pics up

    easiest way is to get yourself an AW11 S/C rear cut and just swap it all over

    I agree whole heartedly. You can't swap the ECU, so you'll need the loom as well, and the extra sensors that the GZE has. You'll need the different crank pulley, all the brackets, the plumbing, possibly some different water hoses on the block, the intake manifold, the intercooler, supercharger, plumbing and all the brackets for that, the different battery mount (I think).

    By far the hardest part will be trying to make the ECU work with the GE harness, and I think you might even need to change plugs on the loom. by the time you've bought all the stuff I just mentione,d found the bits that were missing from your kit and bought them, you would have paid for a full engine. Your locations shouldn't be a problem, almost any importer will happily ship the engine (or halfcut) to you.

    Actually, if you're on a budget and don't want to ship many parts (and you're good with fabrication) a turbo install would actually be much easier and less hassle, you need to make the manifold, dump pipe and exhaust, make some inlet plumbing, and get an AIC to run a boost-referenced injector.

    GZE also has beefier rods and low compression pistons (rumoured to be forged but I think that was proved false). Turbo with stand alone ECU would be simpler than conversion but swapping in a factory GZE would be easiest.

    rods are the same. i.e. same as the NA motors of the same year, AE92 rods are the biggest. only difference between the NA and GZE motors are the pistons.

    i'm currently stripping a Parts car for some other bits i need, but am planning to take the motor etc too (as it is a gze, and my current motor is N/A)

    How much of the loom am i going to need to strip from the parts car? can i plug and play with stuff like the lighting etc, or is it going to be a big headache, and end up with me re wiring the whole car? Do i need to change the fuse boxes too? Can i seperate the engine loom itself and just use that?

    Sorry for all the questions, hopefully someone who has done this before can give me some tips, so i don't double handle stuff.

    The parts car is a jap spec S/C AW11 (haven't checked Y.O.M, but the car i plan on putting it into is a late 87 AU N/A AW11)
