I had PPI do the porting and coating on my intake and exhaust and the overall gain in performance everywhere is more than worth the price by far! I had the exhaust manifold done with the Swain and it will become a bit "tan" in color after some time..but the heat reduction is still way better than an uncoated piece. Pete

Buschur racing, none other for me. If buschur had not done the tests showing real whp gains from doing these, would they be such a popular mod?
I've had my buschur ported mani for a year now (and 20k miles), and it looks as good as the day I put it on. Port the turbine housing and put on a coated SS o2 housing while you're at it, and you are in for some good power gains!

is porting size only to match gasket hole size?
this general engine bay area suffers rusting from the rain
getting through the bonnet vent, is the external coating corrosion
resistant?
what bolts can i use for manifold to head that won't rust?

revmoto, I don't agree with your post. I haven't seen anyone else take the time to do any porting, flowing and dyno testing of the parts except for us. Now there are companies who offer ported intake and exhaust components and 65 mm throttle bodies and actually have used OUR test results for examples to sell THEIR products. I also do not agree that a port job is a port job, that is actually a pretty rediculous statement. I've seen some screwed up porting.
There was a time not long ago everyone thought they needed headers and they were huge sellers, that is not the case anymore.

Sorry Rev, but I'm with DB on this one. If someone besides buschur would do a port job, and do back-to-back testing showing the gains with their port job, AND then guarantee that you'll get the same port job on 100 other manifolds (to yield similar results), then I would consider recommending them. Until then, I see people gasket matching their manifiolds (no no!) and others quoting buschur's numbers for their product.
Shake your head and accuse me of being being a fanboy if you want, but wtf, read the facts.
