I got them from Turbo-Flanges they come only in mild steel but machined already for schedule 10 1.5 pipe. Pretty cheap they sell as a pair for $80. 1.5 schedule 10 pipe has about a 1 ¾ inside diameter so should flow really good especially on a turbo manifold.

 

I also don't see the 5" happening. Not doubting you but I've got a crossover set up and my 4" dp literally sits on the crossover, touches the body, and hugs the frame Very tight. Might have to notch out the body and reweld for clearance.

 

Im not disagreeing with either of you im doing this step by step and learning as I go I take everything here said as helpfull info as you guys have done this already and working around any obstacle I come across. Getting more and more into it today and already have changed up a couple things to make such a big turbo fit, function they way I want, and still look good lol. Def a challenge but really fun I really enjoy this type of stuff. Right now I'm fabing up the passenger side manifold just to get an idea of how everything is gonna fit. Ill post pics later today. Thanks for the comments.

 

Do u think a single 4 won't be enough flow for your setup? A 5inch to 4 inch transition right off the turbo wouldn't kill ya

 

As deep as he's into it for this setup I wouldn't do anything less than 5" myself as well. That being said, 5" with a crossover pipe coming up to the log from the back isn't going to happen

 

Thanks for the Info!!!

 

5" through the hood gets my vote

 

lol funny you mention that I actually might just say screw it and do it haha

 

that's funny. I really like fr8trains car for some reason. At first I wasn't sure but the look really grew on me. If you can deal with the noise, I'd either do it strait out if the front bumper or hood

 

Out the pass fender like black4.8 did
