Nope, that one is The Glass Mans. I'm not sure if hes a member on here or not.



Anyways, I forgot this was supposed to be a thread about wastegate porting so perhaps later I will do that writeup

To answer all your questions,



http://fc3s-pro.com/TECH/HOWTO/howto.html



Then go to turbo turbine housing porting



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
hmm that says nothing about wastegate porting



ill just have to figure it out
