All of the G6 related parts for a start plus or minus a few redundant ones like maybe the clutch pedal if one from a Grand Prix is available, custom mount and possible joint swap on the G6 axle or switch to the BLOWN(mandatory) Saturn or Cobalt 5 spd axles depending on the length of your stock axles and the hub spline.

Thanks , thats a serious thread, i cant read the whole thing right now i gotta run out, Did you complete the swap? Seems pretty involved but not impossible, I have a 5 speed from a 91 grand prix but wasnt sure if it was worth installing because they always bust open... unless im thinking of a 282. The 6 speed might be more durable even tho the 5 speeds more strait forward swap?

If you haven't had any trouble with manual transmissions and you aren't running a high powered engine I don't see a legitimate reason for going through the trouble of this swap unless you have access to the parts already. The newer 5 speed transmission found in the non supercharged version of the same cars mentioned is also a good upgrade strength wise and you can still use your original axles.

I wanted the added strength and fuel economy potential for my swap that's why I chose it. The car is complete except for a bad MAP sensor and tuning along with some planned plumbing changes since the intercooler could not be used as planned and the water/meth system needs to be installed so a good week should be all that is necessary to get it where I want it. Sure took a lot longer than I expected to get it where it is now.

There is a thread here on the swap but the pictures are all in a gallery so there are no details to go along with the pictures incorporated to understand fully what's going on, you can follow it better in this link for the time being.

so you can use a stock 3.1 flywheel with it or no? Also, how do i get axles for a W-body?? You said Moser can make axles for 350 but what information do i need to provide so they can make the right axle? Fiero and w-body axles are different lengths arent they?
