you need 92+ lower trans mounts. to get rid of the bulky upper mount on the older styles. then it will fit no prob, you dont need the front supports, but you could probably put them in, at least on the passenger side to the top of the rad support, im going to pipe the intercooler to sit behind the lip on the z26 bumper when that goes on the car.

you would need the brackets for the trans, and the part on the frame rail and weld them on, i need to find some for my 5 speed :).

I have seen custom setups with the turbo sitting where the battery is. but unless you have a pipe bender it will be hard to make that work

I bored my own throttle body, not sure how much bigger it actually is i had the grind down the 3400 throttle plate to fit, im working on another one to see how big i can go, the one on the car now i notice a difference. i have been doing some experimenting with porting the TB and i may sell them if i get it really good.

Prob be a few days on this new one i have, takes for ever to hone it with a cordless drill and a engine hone, the stones get plugged up fast with aluminum and makes a big mess using oil.

yes the inlet was actually already dam close, but i run the hone through it to smooth it out and polished the opening a little.

This tb i have now im going to hone till i cant go no more, the one on my car i didnt want to wreck it by going to far then i couldnt have drove it lol, i have a spare one now i can hone the crap out of and wont matter if i wreck it, i want to see how far the stock one can go.

the 2.8 TB is a little different inside behind the throttle plate at the top in the 2.8 there is 2 vacum holes, the 3.1 has 1 hole. its inside behind the throttle plate below the top plate with the vacum ports.

I had a 2.8 one all done up, car wouldnt idle proper with it
