about a month back, i traded my 2002 lancer for a 90 300zx, sadly it was auto, 3 weeks after getting it, the transmission started acting up, getting stuck in 3rd gear, wouldnt down shift, did a transmission flush, replaced the TPS, finally gave up and brought it to a shop, they told me it needed a $2000 transmission rebuild, i lucked out that someone was selling a 5speed parts car on craiglist, so i brought that for $700, so we're doing the swap at my school (i take auto repair).
So my questions are, which rear end would be better to use, the auto or manual, also Headers, when is the best time to do it? the parts car came with almost new headers. i go back to school on monday so i could use this info before then. thanks
first picture uptop is my car, the ones on the bottom is the parts car, the body of my car can use some work, the parts car doesnt need much but the bumper fixed but after pulling the motor out, see seen that the frame is starting to twist so gonna junk it after we're done.
