4A-GZE swap. (Q'S) Options

[Niskyspy]

DONT START YELLING!!! I DID USE THE SEARCH FUNCTION BUT DIDN'T FIND ANY GOOD INFO.

Hello, I am a newbi on this forum and I already have some questoins.
I kinda want to do a swap 4A-GZE or 4A-GE. And I have questions about the swap's.

1) Which engine would you recomend and which one is easyer to swap?
2) What do I need, to do a complete swap? if I use stock tranny.
3) Is it possible to do the wiring on my own? (does the wiring job consists of only lenghtheing the wires?)
4) Is there anything else that I should know.

Thats pretty much it. I did find a lot of people talking about these swaps but none of the threads had a list of parts needed to do the swap.
Thank you very much for any info.

I have a 94 ST and im thinking about doing the 4agze swap this summer I have a question though does the transmission for the 4agze mount in easily or are you just gonna bolt it to your stock transmission which I dont think will handle the sc boost very well.

Stock trans should handle just fine as long as you do not abuse it everytime you shift. Remember, Ray halls 20valve 7agte ran and to my knowledge is still running the N/a Mr2 trans rated at 112hp! Just depends on how aggressive you get on it. As for the tranny bolting on with all motor mounts included in the swap is a grey area. My experience with Toyota says yes, but the question is what combo will need to be used. Example is do you need to use the 4agze trans mount or the 7afe trans mount. Will you need to use the 4agze trans mount bracket or the 7afe bracket and with the bracket you choose, will you use the ze trans mount with it or the 7a trans mount? This is the area in which one will have to give feedback during a swap so that we can all get a clear understanding of the right combonation in case it does not line up when installed. Being that it is an A series engine I believe there will be no major issues as I have yet to see major issues while transplanting any A or S series configuration with its chassis counterpart. For example when doing a 4agze swap on an 85-86 mr2, the 4agze trans will not clear the suspension unless you use the 85-86 trans mount bracket. On the 87-89 it works just fine. What we have found with the A series and S series is it is really close if not right on and to get it right on, the right combonation may need to be utilized. Kind of like you need to use the Gt motor mounts in an St to get the 3sgte and drive train to work. Hope that make since.
