Default Trailblazer SS now with 2.9 whipple

Hi everyone, I'm in the middle of doing a L92 swap onto my 07 trailblazer SS. Heads are currently getting a CNC job. I came across a deal that I couldn't pass on for a brand new 5th gen TVS 2300 Maggie.

My question is as far as the front accessories. Do I have to switch over to the Camaro accessories or is it possible to keep the L92/trailblazer accessories. From what I've researched the balancer is the same for L92 and Camaro.

Here's a teaser pic of the supercharger.

The retrofit should be similar to the Whipple 2.9L that guys are putting on their trucks. The Maggie belt tensioner/idler bracket may interfere with the water pump neck which means you will need a Camaro water pump. Also, your alternator probably won't clear the throttle body which is clocked 180 degrees. You can either switch to a Camaro alternator & power steering pump setup or modify your existing bracket to move the alternator more towards the driver's side.

See this thread about the Whipple 2.9L w/jack shaft HERE

Thanks for the advice. I have both sets of accessories also. The 5th gen and the truck setup. I might try switching over to the Camaro setup.

Did some mocking up to motivate myself. Also to see if I wanted to keep the polished blower or go with a black powdercoated one. What do you guys think?

Run the Polished, they look good. I went with black on mine because my truck is black and I thought it looked better, but the polished ones look badass.

Thanks yea I'm going to just keep it as is. Especially since my TBSS is white, and can't complain about the price I got it for.
Btw here are some pics of it, also in the middle of mocking up a set of Brembo brakes

Haha yea, that was me mocking up the calipers. Had to make sure that expensive test was going to work. Now I need to figure out the rotor issue(which I fixed). Should have it all together soon.
