Default 7875 vs gen 2 7875 size difference?

Trying to get a visual on the size difference between the regular vsr 7875 and the new gen 2 7875. My car is kinda tight for space but I might be able to get it to fit. If someone has already posted a pic, I cant find it, please point me in the right direction. Thx

I'm not sure on the size difference from a huron 7875 and a vs gen 1 7875 but the gen 2 is practically the same size as the Huron. Turbine housing just slightly larger to be expected.

I thought the gen 2 went to a 4" exhaust, Matt might know since I think he has used both.

It is a 4" turbine outlet, but you can slap a 4-3.5 or 4-3" reducer on it to connect to your piping without too much impact. Guys have made 800+ on a 3" downpipe and maxed out the Precision 7675 on a 3.5" downpipe closer to 900 so just depends what your goals are.

Besides the turbine being a little girthier I don't see much overall size difference.

Height appears to be the exact same. It bolted straight in. Only thing I done was weld a 4" flange to my exhaust. I didn't realize the original 7875 had a smaller compressor outlet

Don't think I've seen a lb/hr for Precision or the chang's, generally only Garrett and Borg.

The gen2 makes about zero turbo noise. I figured I'd mention that because that's a big deal to some. If you have the sleeper theme going it will be perfect

In comparison to the Huron 7875, its silent. I have a bumper exit which may affect it
