just wondering kinda interested in the R.A.W tb spacer kit. the kit from R.A.W is just a adapter plate it isnt the throtle body it self right. it just alows you to put on a 4.2 TB on there. So if im understanding this right you would not get performance out of the TB plate until you added the 4.2 TB on there. Correct me if im worng. If i am right where would i get a 4.2 TB and what do they cost. i just need to be steered in the right direction. thanks in advance.

 

you can find some on ebay, i wouldn't pay more than about $50 for one, got mine shipped for $55 total off of ebay and that was still a bit much cause i kept getting into bidding wars. They come from Trailblazer 02-05 and the Colorados and a couple other 3.5L or 4.2L GM vehicles. You don't even need the spacer if you're good at porting aluminum, i just ported out the inlet of my supercharger to accomodate the size and then it bolted right up.
