its easier to just put an sr or ka and be done with it.
building up a 4a is a lot of $$$$ plus tranny's are hard to
come by and they are very weak.
P.S. I got KA mounts I had left over if you decide on that swap.
Not true at all, have you ever tried to put an SR into a corolla? It's no simple task.
SR Swap
Routing intercooler piping is a bitch
Unless you space the subframe you have to beat the shit out of the transmission tunnel
Make custom mounts, not easy, very time consuming
Measure correct length for driveshaft that has to be custom made and balanced
Wiring
Cut shifter hole 5"
Cut down E-Brake handle so it doesn't hit shifter
If you want to keep stock cable speedo you have to use a 240/280Z speedo
custom make downpipe
Im sure there is more im missing but you get the point
GZE Swap
Buy GZE
Remove/use old mounts from 4AGE
Use T50 from 4AGE
Wiring
Use a dakota digital Tach adapter or solder a resistor in with the correct ohms
Cut hole in hood if you want to use the stock top mount
Done.
Much more simple, just as strong as an SR, same engine price maby cheaper, cost to modify would be equivalent to an SR.
The ONLY reason I went SR was because I blew my 4AGE, got an amazing deal on an SR, GZE was not finished yet, and im a fabricator.
