Everything in the kit is fine - if you use it exactly as it was designed to be used, which no one here does.

We only have one ceramic coater in the area and apparently his coating does not last longer than 6 months.

Not worth the 1 week downtime it takes to have it done.

If you're coat it use this,
http://www.polydyn.com/performance_coatings.htm.
Realy great for heat control and will last. I know several rotaries that use it and have had no issue to date.

The cost to benifit ratio would not be worth it.

Not counting the downtime. This is my daily driver.

I think cermaic coating is worth it. You could probably find a place closer to you to get a quality ceramic coating. It will make it last longer.

Well, everyone can start out at 6psi (like the GReddy kit was designed for) but once you feel the power and get used to it, it's so easy to turn the boost up

Update:

I got the car back together and after a 5min drive the weld cracked. I was quoted another 4-6hrs to remove the manifold to have it welded again.

I am so sick and tired of these retarted issues, I am seriously considering returning my car back to stock. Anybody want a BNR turbo kit ?

if you take it off and change back to NA then send it to me and I'll see what I can do to duplicate it

frankly I don't like the design from what I've seen, but the turbo placement and other factors may necessitate it

I had shopped a few places I knew and a friend of mine who is a genius with a TIG tried to replicate the GReddy manifold in stainless....needless to say the odd compound curves and shapes made it extremely difficult. Fabricating a replica of the GReddy manifold would be very difficult in anything other than cast...

Of course more power to you if you can/know of someone that can do it!

The stainless fabrication business is my business, my prior work stands for itself

I agree that making it *exactly* like the Greddy manifold isn't feasible, that doesn't mean the pipes can't be routed differently to the identical turbo position

That's cool then, I say go for it! The runners will probably have to routed slightly differently like you mentioned but if all gets to the same place and doesn't interfere with anything than it's all good

The problem is a multiple problem problem. The casting is of poor quality, so is the design( direct 90 bends right out of the engine, and into the turbo) and the fact that you are trying to make the engine breath out of a straw( too small of a turbine wheel/housing)...

^Yeah they did. They had a much simpler straight runner manifold but I believe it required their motor mounts, I could be wrong tho
