HE NEVER MENTIONED THAT

 

the cast manifolds shouldnt have this problem as much because of the thickness, no?

 

I think first you need to differentiate to the people in this thread whether you were talking about an actual aftermarket piece or the stock manifold.

 

Do the porting, good for 7-10whp... Skip on the coating, waste of money.

PPI Extreme port!

Cheers!

 

find yourself another tuner.

 

How much work is it to take out the exhaust mani?

 

Mr. EVO MR you have PM

 

I think you misunderstood what I was saying. I originally thought you had a stock turbo. When you told me that you had a ported red turbo I said that I would gladly do it but would want the turbo here as well so could port match it to the manifold. I never mentioned it would be too thin. It's a thick cast piece and cracking won't be a problem. I did say that it's impossible to port the runners completely through so you're limited to what you can get out of the stock manifold over a tubular one.

You asked several times if it was "worth it" and that depends. The manifold design works well and it will look better after coating but a lot of people don't want to spend that much on an old, stock design manifold. That's why I showed you the coated GT Spec and the Turbotrix manifolds. I was trying to give you all of your options so you could make an informed decision.

 

^ sounds about right... plus tubi headers look awesome

 

based on the info found on evom... only 2 manifolds produce more power then a ported stock manifold.... Full-Race and Shearer stock replacement manifolds.

 

tt sucks i hear nothing but bad news

 

words of wisdom... its a very bad idea to speak negatively about any vendor on Evom. you will get infraction points.

back on topic.

 

Then apparently you don't talk to the right people. They've always helped me out and numerous other people that I know.

They were a huge help and a big arm in the coming together of my old red car that made almost 600 on meth. Car ran great and had no issues except the ones I caused every now and then

 

It has been confirmed that polishing does nothing it may actually hurt performance. Take a look at an engineering fluid mechanics textbook. Porting on the other side does has its performance gains if done correctly. In addition like already said in the thread a cast unit retains heat well.

 

FYI I have had nothing but great experiences with them. I can't even count the amount of times they have helped me sorting problems I might of had and not even charging me. They do great work and are very helpful. Sorry for getting off topic.
