I'm gonna be building a manifold for the Z. Due to the fact that a Holset will soon be making it's home in my engine bay and I need a external wastegate for it and the stock turbo manifold won't with the t4 flange and the need for the WG. Question is that since it's got a divided exhaust housing should I pair three cylinders for one of the housings and likewise for other half or just have all 6 cylinders routed directly into the exhaust housing and not split it? This is a very very very crude example of the manifold I was thinking of making that would split the manifold to feed each side of the exhaust housing. Don't worry it won't look like this and be shorter so I won't hang down so much since all I had to work with were just straight cardboard tubes at work. Everything in black are 90 degree weld-els and and then just T's. Comes out to a total of 8-90's and 5-T's. All done in mild steel cause it's gonna be wrapped in header wrap to help keep heat out of the intake manifold above it so I don't need the stainless and won't have to worry that much about cracking as much hopefully. Suggestions, comments, big boobies pics, other ideas.



all to go here under the intake mani.

Gotta love these awesome Datsun heads

 

which holset are you using? most of them are split-tang t-3's

 

COuld be just a split T3 since he wasn't really sure and has been under the weather and hasn't really got a chance to check it out. Here's the snail that I'm getting

It looks good, just install it already!

 

I would but I still need the turbo and not sure if the masking take will hold that Holset but I'll try. I'll keep one of these nearby when I start it up. :P

 

LOL!!! that was a good one buddy. It is a split t3

 

Nice mock up. That is classic!!!

 

thats hmtness at its finest. :P top quality ----
