I'm pondering the idea of swapping in a Series II L67 into my 92 bonneville. Maybe Spiral can chime in here with some help. I remember he had the swap on his 93. Any help/info would be great. Will the engine mate with my 4T60-E HD? Or do i need the 4T65? Thanks.

Oh geez. Here we go again.

In order to use YOUR 4T60, you need the PCM and wiring harness out of a 1996 ONLY, including ANY Series 2 L67. And you need to do some wiring changes inside your trans to make it compatible.

OTHERWISE, the entire engine, trans, wiring harness and PCM from the donor car with a 4T65E.

that sounds like a lot work. Did you get good deal on motor.

Or you can use a 95 bonnie L36 pcm/harness with a chip. Fiero guys use it all the time.

spiral used his stock wire harness and pcm, just had the pcm reprogramed by gm tuners to my knowledge. The harness is very close from series 1 sc to series 2 sc, i think he had a problem with the wire goin to the egr not bein long enough or somethin, but thats no biggie really.

No I haven't bought a motor yet, but when this one goes, I'd like to swap in a series 2 for a little more power.. and the aftermarket is much better there anyway.

now i woundnt say that....the Series one has all the aftermarket parts that the Series two has except on biggie...and that is in the works

That part has been in the works for a looooong time now. I'd probably be interested in it when it finally comes out, but with the series 2, I have OBD2 and a higher starting point hp and torque wise.

hey Pat...whats :?:

L67 specific.
