Default Where to find log manifolds

Does anyone have any links to companies that make log manifolds for a LS1? I am putting a turbo in my LS1 Miata but can't find a set of manifolds that will work. I have tried LS1, LS3, and L33 headers and nothing fits. They all come close but just won't work...

The only way to get this turbo to work is with log manifolds. All of the threads that come up when I search for log manifolds are old and out of date.

Thanks for the help.

Post some pics of the space your working with and maybe we can figure what fits. The LS4 manifolds may be a possibility, or at least one of them.

flow should be high, i've got 1.75 primaries dumping into 3" logs, tapering to a 2.5 crossover up to the t6 flange, 83mm turbine s480. i had my hotside all thermal coated internally with the nitro titanium coating on the outside to keep the heat inside.

Here are some pictures of the problems...

Driver side with a 5.3L manifold clears and works perfect!







This is the problem. Passenger side with a 5.3L truck header. This is the only issue I have with the headers. If this outlet would clear everything would be perfect...



Clears everything else...




I guess I might have to make a log manifold if I want to put a turbo in this car.

Yeah, they look too low.

The truck headers worked upside down but I just don't like the look. Maybe I should just get over it.
