I made this a new thread because i really want to do this swap, just wanna hear some feedback.
For those that dont know, there is a twin turbo 2.5 liter V6(6a13tt) that was offered in the galant vr-4's; well if it can fit in a galant it can obviously fit in an eclipse right?
....almost.
The 6a13 is mated to an AWD transmission, and our eclipse is obviously not made to be AWD.
Well....there has always been discussion of attaching the 6a12(FWD 2.0 V6 in mitsubishi FTO) transmission to the 6a13. Now we have proof that it actually works, thanks to .org member MivecBoss. BUT the only problem is that the FTO isn't offered in the States, so its transmission is very hard to come by.
After some research i have discovered that the 6a12 and the 4g64 use almost the same exact transmission.
heres some pictures for proof.....somebody let me know if im wrong.
first image is from an eclipse service manual, second is from an fto service manual.

gear ratios....
4g64 6a12
1st 3.583 3.583
2nd 1.947 1.947
3rd 1.379 1.379
4th 1.030 1.030
5th 0.767 0.820
final gear ratio - 3.722 4.312
also 4g64 tranny is listed as "f5m42-2-f6nd" and the 6a12 is listed as "f5m42-2-v7a".
So, obviously it would bolt up, but would the gear ratios affect anything? Does anybody know or see any reason why we couldn't use the 4g64 tranny with the 6a13 motor?
any ideas on this.....
