Ported the WG *pics*
So with a 3" TID and a full corksport exhaust the car was creeping a lot. So we decided to do some porting...
It measures 39mm. The flapper seats perfectly and still has some movement like the stock one. Today the dump pipe is being fabbed up. It should hold boost farely well.

I am about to add a 3" TID to my car, but i still need to port my wastergate Im not looking forward to it. How difficult would you say it was? And that bigger flapper is just welded on to the previous one? Cant tell in the photo

The porting is easy with the dremel like tool we had that hooks up to an air compressor. We had a very agressive bit, and the original 30mm port we did took just a few minutes. We had a 33-34mm dsm valve we were going to get welded on.
We brought it to the shop and he said he'd make it bigger, he ported it to where you see it and made a new flapper out of a very large valve. It is a totally new flapper, it is not welded to the stock one.

Where did you get it done and how much. I got my turbo off. Ready for the porting. Im going to port it so i could use the stock flapper. But i would be interested in making it a bit bigger.

kill it with BOOMSTICK!
That looks like you should have a good improvement, and the job looks top notch. Personally, I would like to see sombody get rid of the waste gate entirely and use a variable geometry turbo for a rex. I know my friend has an '89 shelby dodge daytona with a '91 shelby spirit engine (2.5L I-4 with var. geo. turbo) under the hood. THAT THING FLIES. Also, the best part, you NEVER open the wastegate (it don't have one), and it eliminates some turbo lag. just an idea from the peanut gallery.

You can port to the stock flapper... but that is still a very small port. You can port larger than the stock flapper, while still using the stock flapper. But I would not recommend it, it will give you a lot of lag. Your best bet would be to take it to a machine shop and tell them exactly what you want done, print the picture above to show them. Or if you are up to the task do it yourself.

The flapper is just an exhaust valve off an older v8 motor. he basically just put the valve in the hole, didnt weld it, but he hammered/ tappered teh end so it could still move like the original. Everything else is just as it was on the stocker, just a larger flap (ie the arm sits in the same place and has play in it like the stocker) He did an incredible job, and I can't wait to test this out!

I wish I was driving!
What is that black spot in the center of the runner wall in the "after" pic? Is that a hole? Did you port too thin and break through, or was it intentionally drilled?
