I've got a LS4 throttle body from a trailblazer with 10k miles on it. I had it on my car for maybe 150 miles. The spacer plate was made by my father by tracing the throttle body. It is only 3/8 of an inch thick aluminum. I didn't need it any thicker as my meth is tapped through the intake. Coupler is a 3.5 to 3 inch reducer.

Looking to sell it all together for 130+s/h OBO

 

what color is the coupler?? and why did you only run this set-up for 150 miles??

 

coupler is black.

Bascially just going back to stage 2. I had hoped to get into tuning this car, but i recently bought a house. I have had NO time to really learn how to tune. So I have been selling off all the excess.

The only thing quirky about the bigger T/B that needs to be fine tuned is V/E and idle. First start up and coming to a stop RPM's hang around 1500-2k rpm for like 3-5 seconds. And shifting to second is a bit rough, but its a bit rough on the GM stage 2 tune. Otherwise it was VERY noticable in the upper RPM's when i had it on. The supercharger just screamed soooo much louder. Actually at full throttle shifting into second was normal. Regular daily driving it was kind of annoying.

Had i actually learned tuning or had the money to give someone to tune everything then i probably would not have sold my 60's or be looking to sell this.

 

lowered my rediculously high starting price. thank you stangthang for breaking it down. not sure what i was thinking when i first posted it.

 

sounds like a pretty good deal now if someone wanted to try this....how about those guys that got the Rebel 3" intake but did not get the spacer......good price to try this mod....

 

Would this help me cuz i plan on going turbo so I was wondering if it would help, sorry I am a noob on TB's

 

Sold!
