going twins what brand manifold to buy?

[tirefrier]

I know I need to get a second gen manifold, which brand hold up and performs the best. thanks for the opinions in advance. Dave:charger:

I like my PDI t4 manifold

I've been happy with my ATS.

 

[mhuggler]

I like my ATS as well.:Cheer:

Thinking about it they pretty much all look to be casted the same or very similar. I havent heard bad things from anyone about any of them except having to spend the $$ for one.

I've run HTT, ATS, and I currently have a T4 ATS and a T4 PDI at the house.

I like the HTT because it's smaller and easier to fit the top turbo in twins. But if I had to pick between ATS and PDI, after comparing their T4 manifolds, I would pick PDI

Don't forget about the Jefferson State Diesel equal length header! It can be used in the flipped position

I have 2 ats manifolds and havent had any probs. Never used any others though.

ats t3 for now t4 later

trust me, if you're going T4, get the PDI manifold... needs less work than the ATS T4!

which one should I get for my application. What is the performance gain between the t4 and t3? thanks again.

T4 has a larger exhaust outlet but then you would have to get a turbo with a T4 exhaust housing inlet.

Do they have a www. or you have contact info for them?

Maybe it's just me but I like the idea of a nice contoured adapter to go from the t4 manifold to the t3 turbo. I plan to be running something like this in the near future with my ED gate. Kind of like a one sided venturi into the turbo to spool quick!

Thay look like thay same casting and there's 3 parts to each. How is one less work than the outher?

thay not same casting

the ATS needs more port work

yes, port work... the ATS T4 has ports that aren't that much bigger than their T3 ports. the PDI ports are much larger

Good to know, Thanks Forrest!
