hey i did a swap in my 95 gt, im not too sure on the pedals, i got my pedals from a 94gt, but i did get a 5 speed computer and harness, i did alot of checking before doing my swap and did not want to deal with computer issues, i heard it can act very funny when you shift. so i went with a harness and computer from ebay.
i dont know why you would have to mess with the map sensor? i didnt and have not had one problem other than buying tires more often.
if you really want to enjoy it i would suggest going for a 5 speed harness and computer, it will make the install a whole lot easier, also before you do the swap i would suggest swaping out the pedals before hand, it takes about 2 hours and is pretty easy.
if you got any questions email me at
punksab2000@yahoo.com and i will help anyway i can. i did my swap in about 10 hours.
