Im ressurecting this to add my thoughts. Wouldnt the time and effort on getting both cars going be the same. Yes with a GGSX you have to swap a bunch of stuff, but I see it the same as if you bought a VR4, With the VR4 you would end up pulling alot of stuff out, IE: 4WS, ABS. Dbossman has it right with the time, money and effort factors. You can get a car that has a bunch of stuff you will rip out or you can get a car that you will end up adding a bunch of stuff to.
Earlier Donkeylips said something similar to what I just said, In a nutshell the GGSX is the same platform minus all the unwanted stuff, You just have to add a motor trans and rear end if you like and your Off! If you like the Vr4 Bumper you can buy one and put it on! Some people have to have their dash badges and Key Fobs though,
Right now I have a VR4 Shell with all parts ready to Go, Rebuilt Tranny, Motor just sitting waiting for me to throw her together when I get some time. Im considering selling the shell and buying a GGSX because of ease of the job to swap over the trans and Motor add some wires for knock and maf and im drivin again. Plus I can sell the NA 4G63 to a buddy that has been waiting for a motor to replace his in his Galant GS. Geez So many decisions!
