throttle body not 3 bolt i replaced my thermostat with a 180* the other day and noticed that my throttle body was a 4 bolt instead of a 3 bolt. i was wantin to get the new weiand intake when it comes and that would be great if i didn't have to replace the tb at first. should my 4 bolt tb hook up? which tb do i exactly have, i couldn't find it online anywhere. GM part number: 19906F2030. thanks in advance

ya i know it wont fit the 90mm, but the intake comes with an adapter(im not sure what size, maybe 78mm) hopefully it will work. eventually i'll probably get the 90mm

does anyone know what our stock throttle body size is (mm)? thats i 3 bolt i believe. somehow i have a 4-bolt. i'm guessing the same as the 4.2L trailblazer or 5.3L trucks. what are the sizes of the throttle bodies on a trailblazer or 5.3 truck? just wondering because i want the new weiand intake if it ever comes out

Search, search, search. We all have a 4 bolt tb. They are the same as the 4.2L inline 6 cyl. tb on trailblazer/envoys. Last time I post it. As far as this intake for LS4's and adapters and blah blah blah... I guess we'll see it like when diaBLOWShite has trans support. I e-mailed weiand about this so called LS4 intake and guess what....no reply. Big surprise, I doubt its being made for our cars. But hey, what do I know. Think you need to read the fine print.

the weiand intake isn't made especially for the ls4. its for all ls engines. i know some modifications will have to be made. i was just wanting to get the intake at first and not having to spend an extra 400 bucks on a throttle body

and our stock t-stats are 187*... so you're not gaining much, if anything, with that swap...

thanks but i read that 160* was too low. and the additive is supposed to help it run cooler. its not like it was an expensive mod and every little bit helps.
