Finally finished my new manifold to control the boost problems I was having.. Fitment was a PIA..





wastegates plumbed back into the downpipe...

 

aint that perdy

 

You couldnt make the wastegate placement further up near the hotside? Other than that looks great. Im sure that would fix your boost problems since your running twin 44mm lol.

 

Impressive..

 

There will be plenty of pressure and flow where they are at since they are at a bend and also straight in line with the sleeves. Also, there was no way I could fit both of them anywhere else, I could hardly fit one single one up by the turbine housing...

 

Looks very nice. Mine's similar in concept, with short runners. I'm also using twin Tial 44s. I'm only running 9 psi (which I understand requires more WG area than higher boost levels), and I have no problems with boost creep. I don't know how much the totally separated runners helped, buy my A-Spec GT35R with 1.00 A/R T4 hotside reaches full boost by 3500 RPM.

 

only problems I forsee is the long wastegate pipe may crack since it will be going through several rapid heat cycles and no way for it to flex. i'd put a flex bellow in it. other than that looks good.

 

yeah, I had a flex joint in the old one, but its just so damn big I didn't think I was gonna be able to fit it without a whole lot more modification.

 

I did it similarly , but I put the gates as close to the turbo flange as I could have , also mine is made of schedule 40 carbon steel , heavier , but EXTREMLY durable and wayy cheaper !!
