Buschur Ported exhaust manifold, how much was YOURS ported?
Have installed both BR ported manifolds and PPI. The first PPI I had was a little rough and beyond the turbine gasket. The other was a bit better. At the head they really took a lot out. It was well on its way to being gasket matched. Which is not a good idea on an EVO as many can attest too. The BR manifolds were exactly to the turbine gasket and well cleaned up on the runners. Nothing crazy. As Dave said, inline with being matched using a 1g gasket.
Most of my testing is with the manifold, and O2 housing being swapped at the same time. So actual gains from just the ported manifold is hard to say for an average car.
A local guy came in with his own ported manifold. I was afraid the cast flange at the head would break off it was so thin. He did port it to the stock EVO gasket. He also will not listen and let me put on a stock manifold just to show him how much it is losing. Its an 03 running a red on E85 on 30 psi.
Heat coatings are great. Have used many different companies over the years. Lucky to have a local coater that is top notch. They do private label coatings for Yoshi, etc.
Been using their piston coatings on manifolds for years now. Turbine and O2 housings too. Good to temps well over 2000. Also used the Ceramachrome coatings that last to 1600-1700. Use it on the manifolds heat shield. You combine manifold, turbine and O2 housings all being coated with the DP. Makes for one fast spooling setup and much nicer underhood temps. For the stealthy EVO look even had the back half of my BR exhaust system coated flat black.
Its all about the combination of parts. You can have ten good parts on your car and two really poor choices and pretty much be at square one with performance.

I have never gasket matched a manifold, only port matched them on the head side from a template I have made. My porting template is considerably smaller from a head gasket thanks though.
I just recieved my ppi manifold and it looks fantastic. I usually won't say things in a thread like this but basic philosophy and human nature has us living in a box. We believe the parts any results that db and other vendors put up. If we don't question the parts and if something may be better than db might as well own the only Evo shop and we would all have his parts. (not bashing I really do like his parts, just an example). If u want to figure out what works, question the vendors on Here and figure it out on your own by doing testing that will question these parts.
I appreciate the positive words and being a small shop it means a lot to me.
Thank You,
Wayne
I've had two stock-appearing turbos ported by Buschur as well as an exhaust manifold. The port work was exceptionally precise and even on all of them and extremely reasonably priced. Plus, my car always seemed to make better power than other equivalently modded cars in the area. That was especially true on my BR-ported FP Red, even before my recent full build. Those results are what convinced me to recently go forward with BR porting on the intake manifold and head and the results did not disappoint. Whoever is working for Buschur on the port work is doing a great job IMO.

I appreciate the support and kind words!
I take pride in our porting and coating as well as the other parts we bring to the motorsport community
Over the years I have had vendors create threads about me, threaten me and pm members here slandering me all while spreading lies for their own benefit. Little do they know it makes them look childish. I refuse to play their games and get involved with their drama. PPI is above all that.
If anyone has any questions about porting & coating services feel free to pm me, email or call.
Thank You,

PPI
Plus if I'm not mistaken PPI got the first 80mm FP red hotside from me
. Car runs great and makes great power the proof is in my number: https://www.evolutionm.net/forums/ev...mp-469whp.htmlThanks again Wayne for the great port work.

Personally I think that you can do all of the anti reversion tricks you want to, but the turbo is actually such a big restriction to exhaust flow anyways.
Working a DPR has taught me the importance of velocity and temperature, and going too big on any ports can really slow down the spped/energy of the flow. Reversion also is a bigger issue with cams with big overlap.
By no means am I disagreeing with AWDCOUPE, just my .02
Either way, I believe the OP got his answer
