- A quick guide on how to port your internal wastegate to eliminate boost creep & aid boost control. In this video I'll be porting the turbine housing of a GT2871r.
If you're interested in having your turbo ported or require a rebuild, head over to www.onboostperformance.com or send me an email at contact@onboostperformance.com and I'll be happy to help!

Appreciate the simple tutorial 👍 You make it look simple enough I could do it, look forward to seeing your next video. Perhaps we will get to see a turbo on your lathe.
Thanks man!
Not sure if I want to reveal that one yet ;)
The only tutorial that doesend talk shit for half an hour
Nice
How much do you take off? I’ve read on forums for my CT9 hybrid to take off roughly 2mm and do you go all the way to the inside of the port?
A step drill is not strong enough to open a round hole?
is there any chance you can measure and tell me the stock diameter of the wastegate port? i'd be really grateful if you can help me. thank you!
Can I weld the flapper close and use an aftermarket wastegate if my manifold has an aftermarket wastegate spot.?
Yes
Hey you have you s13 with stage 2 for chip turbonoz . I have gt28 its work with same chip .. ?????
T28 and gt28 its básicly the same but gt28 i think is ball bearing…
They are nowhere near the same. Proceed at your own risk
Hello mate, did it fix the boost creep? I am trying to hold 12psi on my 1.8l engine but it creeps. Is porting the WG like you did help me hold that low of a boost level? Thanks in advance, great video!!!
It will fix boost creep, thats the aim of this mod. Yes it will help you maintain a lower boost pressure
