Clean DIY install of the 90mm LS3/LS7 throttle body. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

ZL WON · 06-22-2012, 05:46 PM

The only draw back of going with the larger 90mm throttle body of the ZL1 factory 87mm throttle body is that is looks hideous. Below is a picture of what it would look like mounted to the snout without making any changes to the air inlet.

This is what it will look like with a small modification to the air inlet pipe.

In order to flip the TB 180 degrees you need to make a very small modification tot he air inlet. Below are some photos I took describing what needs to be done to make this a very clean install and not have to look at the bulky actuator housing on the 90mm TB.

I hope this helps.

Nice, this is probably going to be my first mod.

Great description in plain english with highlights and tools in the same picture. You should write service manuals. A+

ZLWON..Thanks again for the instructions...Very thoughtful of you to put these pics on here. Did mine today..took like 10 minutes start to finish. I did notice when I took original TB off, a couple of the bolts weren't really very tight at all.

The LS7 TB works flawlessly, and I know it could be my imagination, but the car feels snappier. roll on the throttle in second seems better than before.

Very easy mod, and not expensive, and faster to do with the aid of your instructions.
