7AFE to 5SFE ?, Upgrade 25hp? Options

[bigblock261]

I have a '95 ST Liftback 5 speed (AT200) with a bad 7AFE. I kinda hate to replace it with another anemic 7AFE but I'm not up to the 3SGTE swap. I see no mention of a 7AFE to 5SFE swap on the boards except that it is not plug-and-play and it is as much trouble as a 4AGE 20V or a 3SGTE.
MY question: What is required to upgrade my AT200 from 7AFE to 5SFE, and what year or years ST204 GT should I select as a donor car?
I'm hoping to hear I'll need the ECU and engine wiring harness from the ST204 and that the engine will bolt up to my transaxle. If the swap requires harness splicing and pinout changes I'll probably just settle for 110 HP and stick with the 7AFE. Thanks for any info.

Yes, these shops do exist.... But the problem is them being in such remote locations. Truthfully most "tuner" shops should be able to handle this, in reality they dont know much then you do sometimes.

Only shops I know of that are "Pro's" at toyota swaps are EL Prototypes in Los Angeles Area and another shop in Florida somewhere, where all they do is toyota swaps.

My swap dosnt work because of who I went to. I also had Qatar do my wiring, which seems to be my only problem, mechanicly the engine sits and runs fine.

Almost any shop will be able to handle a 7a-fe to 5s-fe swap. Most shops should be able to handle a 7a-fe or 5s-fe swap to a 3s-gte having dificulties when it comes to wiring. Same go's with a 7a-fe to 4a-ge.

Lar's recent post of his teammates car's is proof that almost anything can be done. There is a st-204 with a Caldina 3s-gte with AWD automatic w/ tiptronic transmision.

Just do research before doing any of these swaps, and make sure your shop knows what to do, not just think they can.


also, on a side note: a 7a-fe to 5s-fe swap is not going to be worth the money as the difference is not that noticable, and therefore should only do a 3s or 4a swap or stick with a 7a-fe
