Help with my first swap please!

If you're going for that much power you should probably rebuild the transmission, transmissions usually last 150-200k typically.

I vote swap still, the TH125C is GARBAGE, it's my main reason for going 5 speed, not because my trans was toast, but because it was a crappy trans, three forward speeds, thats it. the torque converter lockup drops the rpm's more than the shifts...

Yeah, note my edit after I noticed it was a 3 spd, lol.

If you're going for that much power you should probably rebuild the transmission, transmissions usually last 150-200k typically. After seeing its a 3 speed from what the guy above me says though, I would replace it with a performance built 4t60. And actually for $6k you could get a 3.6 DI which has your power goals right out of the box, but its uncharted territory so far as I know. And paying someone else to figure it out would put you over budget if you couldn't do it yourself. Someone seriously needs to start cranking out standalone ECUs for that motor, I want a 3.6 DI in my camaro bad...as much power as an ls1 in a small lightweight, v6, could have my handling and my power.

I would stay away from the DI motor, it would have a ridiculous pricetag just to get in the car, and we're not talking running either. spend your money wisely, get an LX9 and a cam, have a fun DD, and a reliable car.

If you paid someone else to put it in yeah. But if you did it yourself it would cost about the same as an ls1 swap into a 3rd gen fbody does.

The TH125C was an ok transmssion, back in 85.

Yes you need to replace the transmission if you want something decent.

btw I build Fiero swap harnesses.
