Hot side tubing crossover behind and underneath?
I was looking into doing the hot side tubing crossover for a turbo behind the motor/underneath the converter and coming back up front on the other side. Has anyone done this cleanly? Can you point me in the direction of some pictures?
I'll be running an LQ4 with a 4L80E in a 72 Nova probably with truck or f-body manifolds.

This was done on the TTi street kits for F-Body cars, as well as the PTK and ebay turbo kits. This is also standard practice on Grand National and T type Buicks.
I ran a setup where the passenger side crossed over behind the trans and back forward towards the drivers side where it merged.
Here's some unsolicited advise...Calculate the crossover piping size needed. A situation like this where the crossover is too large can cause some lag or response issues. I'm not saying that it will be severe, but you just want the best for your setup.
Example, 2.5 vs. 2.25 vs. 2 inch cross over piping.
Do your math. Good luck.

We did this on my setup. Stock LQ4 manifolds, driver's in OEM position with vband, crossover down under and up on pass side merging, then into T6. Pics in link below.

The reason why i'm doing it on my nova is because I built a log style manifold a few years ago for my corvette and I figured I would use it instead of building another kit . And I like the way it looks.
