Anyone know how time consuming or how much of a pain in the ass this is, the buddy of mine who installed my kit told me he would be willing to do it, for the re-installation of my Test Pipe, just wondering how difficult, we have every tool ever imaginable

 

why not just buy a bigger wastegate?

 

joey has an internal wastegate.. he has the greddy kit

 

you can only do so much but if you go too big you compromise the sealing surface which can lead to disaster. i've seen yashio factory do it in a magazine. but thats about it.

 

I think you just grind out the whole under the flap, but if you make your whole to big and it no longer seals your gonna have some problems $$$. I think just a little can help a lot.

 

Grinding the hole bigger isn't the hard part. You have to cut into the outer wall of the down pipe flange to fit the larger flapper. You also need to weld a new flapper into place. Spatter will destroy your turbo, along with the flapper breaking its weld, if done incorrectly. The mating face should be machined out for a proper seal, or you'll always have an open gate.

 

forget that, seems like to much of a hassle,

Revenge, did you have any creep issues with the Berk HFC?

 

Its probably one of the easiest internal WGs to port, due to the shape of the turbo housing and the direction the WG opens. You only need to the port the sides .05" to get a 23% flow increase.



Removing the exhaust housing is easy, so is opening the DP flange. You can even buy larger 304SS flappers online if needed. The welding is not hard.
I've got an exhaust upgrade in the works - I'll port my WG then.
There are shops that will port it also.

 

KART is my hero.

 

I stand corrected. Looked like quite the undertaking from what I was told.
