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. |

To change over the 5s all you would have to change, like a 7a-fe to 3s swap would be:
Engine Electrical system Transaxle Engine/tranny mounts ECU and wiring harness I dont know why there would be wiring problems.... if its a USDM harness it should be plug and play (a 5S-FE harness) But the wiring of the 3S has to be lengthened, and if its from a 2nd gen, rewired to fit into the internal harness. This would not need to be redone considering that the internal harness from a 7a-fe and 5s-fe are the same. |
