Well, Josh (1low86svo) had this header on his 86 but decided to go back to stock. So, in my neverending search for cool stuff I said "I'll give it a go!!" Anyways, I believe he bought from a guy called Giamanut over on turboford. It's mild steel construction, tubular, stock location, no EGR.
Wanted to see how it ran but also wanted to test a high temp coating to aid longevity of the header but also to lower engine bay temps. There is a local company, Finish Line Coatings (.com), who coated it with their high temp "turbo" coating which is supposed to withstand 2000*. I think the coating process, internal and external, was $130.
I also aquired an SCE copper exhaust gasket in a trade with jcamper so that went in too.
Josh and i tried a few different ways to get it on, which involved R&R'ing it several times and concluded that the best way to install this item is to install the header and then bolt the turbo on once the header is fully bolted to the engine. Not the standard technique I realise, but the easiest way to do it and the only way that will allow all 8 fasteners to be used. BTW, the fasteners we used were M10x1.25x16mm with an 8mm allen head. We also had to make a cut in the lower half of the stock IC for clearance. A TC IC doesn't need to be cut but I thin k they look ugly. Sorry
Now, I can't attest for the longevity of the header yet, only travelled about 15 miles with it on, but the coating certainly does the business. After our initial run-in "thrashing", which involved being in the boost a lot!!!, the IC was cool to the touch. For reference, I could put my hand on a header tube 5 mins after shut down whereas the water coolant feed line going to the turbo was still scolding. I'm yet to do actual temp readings but when I do I'll post the data.
Hp gain, don't know yet, couldn't get to a dyno if i wanted to, SNOW!!!!, but the turbo seems to spool quicker and it does sound a little meaner.
If one of Rod's headers had been more readily available when this project started, prior to the Reunion, I probabpy would've grabbed one beacuse it's a proven product and can be had with an EGR, but this was at hand at the time so we'll see how it goes. Enjoy
