what size do you port the wastegate passage to when you do the 34mm flapper mod on an EVOIII B16g
Thanks

31-32mm is what I've read.

how big of a flapper can I put on my 14b. And where do you get one from, and how hard is it to put on. Is this something I can do in my garage?

I was told by slowboy that I could sent my turbo to them or have a local machine shop do it. Maybe if you have a drill press.

you can buy one from them or sent it to them and have them do it. I just ordered the flapper from them for $29

The 34mm flapper works great i've never seen boost creep since i had it installed by slowboy.

On a 14b, the biggest I could hog the hole out so the flapper didn't bind was 28mm. Go to big, and the flapper doesn't seal right.

He meant port the WG hole to 28mm. TRE recommends 28-30mm

20$ is the price of just the flapper, 29$ includes shipping and handling using paypal. Just thought i'd clear that up.
