so, have any of you ported your wastegates yourself?

I did it on my old stock 87 turbo. Were you looking for a walkthrough or...?

what exactly will this feat accomplish?

To answer all your questions,

Then go to turbo turbine housing porting https://www.nopistons.com/forums/pub...IR#>/smile.png



The benefit of the wastegate porting would be less chance of boost creep. After doing this to mine I didnt get boost creep at ALL, but I also ported mine so large I suspect a little boost was leaking at all times.





The turbine exhaust inlet porting, in conjunction with removing the twin scroll, got me the 1psi back that I lost in the wastegate porting.



So whereas before, it would be at 5 in gears 1 and 2, then spike to 7 or almost 8 in 3-5, after the work was done it would be above 6 in gears 1-2 and close to 7 through the rest.



If I feel like it I might make my own write up on all the steps, tools needed and what not to do this https://www.nopistons.com/forums/pub...IR#>/smile.png
