damn, thats a bad b*tch right there

 

For 99-02 trucks you can run a 90mm UMI T/B Chris thunder550 Had one.

 

will the trailblazer ss tb plug in to a 03 silverado or how do i get it to work ??

 

I was wondering the same thing about what TB to use. I think people are having to get a Dr X harness and run a Corvette throttle body or something like that. I wanted to make sure about this as I am starting to horde parts for my truck and Camaro build

 

you need the torquerush harness for either t-body to work.

 

i used the dr.x harness (torquerushdotcom) with a stock tbss 90mm throttle body that came with the manifold. I also used the tbss fuel rails with my 8.1 injectors. i got rid of the evap crap, and plugged the passenger side vent line on the valve cover. thats pretty much all to it

 

did you disconnect your pcv?

 

How does this intake compair to a L92? I have been reading on that intake and those heads and they seem pretty good. Since I am in the air about what heads I will run I am up in the air also about intake. Thanks
