another good place to check that i use, they have just about everything you;ll need except the ls head flange

Wasnt there a turbo kit out of the trucks that utilized a cast manifold on the pass side and a tubular on the driver side? Is this a bad setup? I had to do this on my car since the tubular I was originally going to run hit the mount on my pass side, forcing me to use a cast manifold.

Everyone is using the term “flow” when they should be using the term “pressure differential”.
How can anyone talk flow when the exhaust gets to the turbine housing it has to pass through
2 holes with the area slightly larger than a golf ball. One being a .96 T4 housing and the other
being the wastegate.
There maybe some advantages to a full on tube header on a 2500 HP race only max effort
race car.
If one of these guys would put a set of “log headers” on there 2500 HP race car
you would be surprised at how much power it would make.
They don’t look as sexy as a set of headers so they must not work… right?

ZZP put 900 to the wheels on a 2.0 liter, log manifold, and T3 turbine turbo. The manifold was originally made from sch 10 elbows and now cast for them.

have you read what corky bell has to say on the subject? you could've gone with an individual primary design on the setup you guys are marketing, but didnt. why? log manifolds are not only going to inhibit power, spool, but they're also less durable. they dont allow for expansion/contraction like an individual primary setup.
also, you claim power capabilities of 1800, where do you get that number? and since when is engineering taken so lightly on a setup making that kind of power?

I'd love to use truck manifolds but its in a Thirdgen camaro and the Power Steering gear box is in the way. I know you can cut the flanges off and weld V-bands but its cast iron and seems like a potential headache. Its been done before. I could use Truck Shorty Headers and weld v-bands to them, or custom build mild stell headers and get them coated, or check into log manifolds which is kinda ify.. Not a bunch of info on them.

Truck manis work in third gens facing forward and up without modification. I'm not a fan of the look so ill be doing custom stainless headers. I have about 600 bucks in flanges and pipe for the complete setup.

99 fbody passenger side manifold fits on the drivers side without hitting the steering box, I have one if your interested... I just couldn't find one for the drivers side and didn't want to go the welded v band flange route either, so I decided on custom stainless headers.

Mercury racing has a bigger budget than most of us, they could have used
anything they choose....... looks like "logs" to me!!!!

I think the truck guys have proven the durability and performance of the fabricated
manifold.
Like it or not there not the kiss of death some make them out to be.
You can do things with weld els in tight places that can't be done any other way
with common fab tools.

you could have done an individual primary header, plain and simple. even with the turbo's in the same spot.
