Here is the HKS manifold that Greg is using.
Had any feedback on this one?

That's the manifold for the T4 series, right? IIRC, no-one has been having
problems with those cracking. Although, I think a lot of the problems with
the car version of the 13BT comes from the pre-catalyst - I have *never*
heard of one making it intact past 100K miles. Since it is fairly
close-coupled to the turbo (gee, Mazda did something else before honda and
the others - go figure) the backpressure and resultant heat really take a
toll in terms of metal fatigue, gasket life, and wiring. I will be replacing
my entire engine harness with aircraft engine wire (it's the stuff with the
fairly thick grey silicone insulation - I can look up MS spec tomorrow) and
cannon plugs due to the embrittlement of the copper original harness. It is
a testament to how easy it is to make a rotary engine run, that my car ran
at all. I had NO emissions solenoid continuity, boost control cont., BAC
cont., etc. I think the only things getting through were CAS and injector :)

Check your nylon apex seal oil injector hoses and replace those too Mike.
Those will kill your engine for sure.
