Just making sure I'm right here...To swap a 90mm Tb to our DBW vehicles, requires any kind of 90mm tb we can find, and the Dr X harness and thats it? Other than the intake of course...

Or is there any 90mm tb that is a direct bolt on and go for us?

 

Yes, you will need a 90mm throttle body, dr x harness and some kind of 4 bolt intake for the new tb. Most people go with a tbss intake manifold and tb swap because it is a direct bolt on. A 90mm tb will not work with your stock 3 bolt manifold unless you can find a 3-4 bolt adapter which would probably cost the same as buying a tbss intake and not really net any gains.

 

He's gettin rid of the stock intake but not running the tbss intake

 

or you can run an o2 tac module with a 90mm wire harness adapter

 

IF i remember roight the car TB's open the opposite way..The maggie tbssers used the ls7 to fix throttle issues..

 

Could you explain this a little more?

 

the guys with the TAC mod were having problems getting 100% from the TB, hence the need for the X-link which if you go to torquerush dot com you can see what TBs are compatable I believe. It's been a long while but take a looky.
