I was curious, are all LS4 throttle bodies the same? Could I get one off of a trailblazer or envoy or a grand prix gxp and would it work on the lsj?

 

do a search and ye shall find out

2006–2007 Chevrolet Monte Carlo SS
2005–2008 Pontiac Grand Prix GXP
2008–2009 Buick LaCrosse Super

 

I read on another thread that it comes in many different GM cars and trucks, so I assume they're the same, but I was just wondering if the LS4 tb's that ZZP sells are modified to fit or if they'll all fit regardless.

 

you have to run a ls4 spacer or open the blower up for it the tvs is a direct bolt on

 

Yeah I'm just going to port the blower haha, thanks guys

If it makes you feel any better. I got one off a Trailblazer that I am using. I also have my blower ported.
