Just bought this mani did I use profanity in a thread title?
So I just bought this manifold off of ebay and I paid 75 bucks for it and as you can see it is cast with a t2 flange. The guy that posted it said it was for a corksport but I think he is wrong. Anyway he had it on his 1.8 and I figure Ill plug the bung and put it on my 94. I was going to post before I bought it but I was afraid some ******* would see it as a good deal and buy it before me. So I basically had a decision to place a 75 dollar bet that this was in decent shape considering its cast and has similar traits to some of the older HKS manifolds and BEGI manifolds if seen on here.

I'll know more on its condition when it comes in mail. I am thinking about getting it ceramic coated if I can get a good deal on the service locally, cause it is such a small part. I am only trying to make 200whp. I think this will be more than capable. Im still going to run inconel hardware just to be safe and probably scoop up a 2554 turbo.

I think its ok its cast so you know how that goes as far as shape. Still better than an obx or megan manifold. Haha the only reason for inconel is for the drift and autox events and it gets super hot in Texas and I would hate to snap a bolt. The seller said he took it off a running car.

Direct quote from trackspeed. I understand.
" The stresses and strains of extreme thermal cycling, high-RPM vibration and high g-force cornering combine to exceed the high-temperature yield strength of standard mild steel or normal 304/316 Stainless steel studs. As the yield strength of the fastener is exceeded, it begins to expand, or creep, causing an immediate reduction in preload on the nuts � akin to literally loosening them with awrench. Once the fastener has worked its way loose, vibration will continue to spin the fastener off. If a high quality locking nut is used, the entire stud will spin out of the manifold. Safety-wiring all four nuts and studs together is only a temporary fix � after only a few sessions a steel stud will creepand cause exhaust leaks regardless.
A material-based problem requires a material-based solution. Enter Inconel, a nickel-based superalloy that sees duty in environments such as jet engines and nuclear reactors. Inconel is available in a wide variety of alloys, allowing Trackspeed to select an alloy that had a similar coefficient of thermal expansion to steel, but far higher high-temperature yield strength. Inconel studs do not exhibit the same creep when exposed to high-temperature stresses, allowing the fastener to maintain preload and work as intended.
Trackspeed Engineering�s Inconel studs are machined in the United States of Americaspecifically for use in turbocharged Miatas. Because these are not off-the-shelf items, we are able to specify exact dimensions to ensure adequate thread engagement in the manifold as well as ease of installation with the manifold in the car. In addition, we were able to specify rolled threads which cause less stress concentration during production and result in a superior fastener. The end result is an exceptionally high-quality stud designed specifically for cast manifolds tapped to M10x1.50.
In order to complement our high-quality studs, we have chosen two products of similar quality. Stage 8 Fasteners provides the nuts, retainers,and clips for our kit. These nuts are significantly easier and faster to install than standard locking nuts or copper split-locking nuts. Once the nuts are all installed and tightened, retainers and clips are installed. If one of the nuts attempts toback its way off of the stud, the retainer interferes with its surroundings and prevents the nut from loosening any further. In order to fasten the stud into the manifold, Resbond 907TS thread locker is used. 907TS does not exhibit the temperature deactivation that other chemical thread lockers do, but is still mild enoughto be removed with hand tools should the need ever arise. It is the ideal thread locker to complement our studs"

Didn't think about that but I edumicated myself in them a little more and now I want them more than before. I just many to be able set my turbo and manifold together and not have to worry of it moving. No matter what.
