as far as supporting mods i am hopefully going with the hks gt2835. I already have ferrea valves (2mm over size)and plan on going with their retainers, springs and spring seat locaters, not sure about cams yet though we have to measure the piston to valve clearence. I want to get a set of some 1000+cc injectors to go with the setup. My friend is going to be making me a set of mani's i hope but have to get the turbos first. I am hoping to have an upper plenum made also. Just kinda getting worried about the stock rear end and tranny.
