Just answer me 1 or 2 and will it fit without any problems?

 

AFAIK you cannot just hook up a 90mm. The bolt pattern is different and you will need an X-Link from torquerushdotcom.

 

damn that thing is double the price of the throttle Body I think im gonna take that next month.

But will any of those work from the 2 links I posted?

 

You're 08 should already have a 90mm tb from the factory.

 

Really? On a 5.3? Damn!

 

isn't it like an 87mm? still 3mm diameter is not worth all the hassel

 

I'm gonna check tommorrow

even If its a 90mm or 87mm im not gonna change it but if its 78mm that will be changed

 

Damn I didn't know that!

 

im not 100% sure but i think all 08's got the TBSS intake and TB

 

Yes, you should already have the identical TB as shown in the first link. The second one is the LS2/LS7 car style. $100 is very cheap for the LS7 TB. I haven't seen one for under $200 in a long time. We'll see what it goes for. $99 is reasonable for the truck style 90mm. You can pick up a new one for $135.
