Porting CT9 wastegate

[wakeabby14]

Is it worth the time porting the stock CT9 wastegate as i will getting an electronic boost controller soon and i want to prevent as much creep as possible, Please let me know your experience and opinions as i am changing my manifold tomorrow so i could do it at the same time while the turbo is off the mani.

Thanks josh

You'll still get boost creep, it'll help matters but not by much. Are you still running the standard manifold too?

Better than the standard though, the port restrictions on 2&3 are an issue.

if you port it enough should solve boost creep. Mine did. Shut the penny and mark around the outside. Then port as close to the line as you can i left about a 1mm

Will get on it then, Any recommendations on the best bit to use on the dremmel?

[Starlet__SR]

Use a coarse bit to remove most of the material, then a sanding wheel to tidy things up.

Just a bump up did you put anything inside to stop all the crap going in please?

[Starlet__SR]

I used play dough to seal the exhaust wheel and stop any shavings going in, the front I used tape.

Oh maybe I'm thinking wrong here mate, I always thought you just shaved off the hole, behind the waste gate penny and that's it?

That's the main part of it. Always helps to dress up the cavity inside so it can flow a little better.

Hi. I would like to know if I will be able to lower the 2&3 custom exhaust mani restrictions without ruining it. The restrictions are the stud bumps that shouldn't be lowered.
