What turbo manifold to get? There arent many options out there....
I'm looking around for turbo manifolds for a 1.8l 96 miata but I am having a hard time finding them. The only ones were the JGS, Begi, and HKS. Are there any other ones out there that I am missing? I cant seem to find any other turbo manifolds.

But seriously, I'd rather have a stroke than deal with Bell Engineering ever again. Go with a custom manifold from Absurdflow or order a manifold/downpipe combo from FM (you can order individual parts from them), source your own turbo/water lines, and buy an intercooler and generic pipe kit from eBay and fabricate/assemble it yourself.

You're an idiot if you go with cast iron. I don't even know if Tim will make another absurdflow manifold for you, but if you don't buy that you're a moron too. You can read through the long *** threads on here and come to those conclusions yourself.
Ive been reading a lot of the old threads and still don't see a straight answer to choose cast iron or tubular. I see that the JGS manifold cracked on some people already but am not sure if the JGS cast manifold will 'always' crack or only a few percentages cracked. The Begi seems to have bad airflow. So that really only leaves the option to absurdflow. Though the price for absurdflow is really high (as I am only planning to boost 6-7 psi only and don't want to spend that much on a turbo manifold). I have pieced turbo system already but am having a lot of trouble finding/deciding which manifold to get. There doesn't seem to be a certain manifold that everyone gets and recommends.
May I ask what manifold you are using and for how long now? Previous experience with other manifolds also?

If you want to track the car and you buy something other than a v-band manifold you're wasting your money.

Under these conditions, cast manifolds using conventional hardware seem to have trouble with the studs / nuts holding the turbo to the manifold loosening. We're not talking about turbos falling off or anything, just enough to cause a leak. A couple of companies are looking into the use of studs made from a material that was given to the CIA by aliens in 1953 (in exchange for a permit to harvest as many cow lips as they desire) and just recently acquired by the mainstream metallurgists' community, at a cost of many lives. No real-world data yet on their effectiveness.
The only real factor here is whether or not you do track days. And I don't mean AutoX, we're talking 30+ minute sessions at >100 MPH where you're at WOT most of the time.
