porting the wastegate?

Ok, I contacted the local rx7 specialists in my area and they will not port my wastegate even if I take them off the car for them. "no machine work"
Anyways, anyone know of a good shop that will? How hard would it be for me to do it myself?

Thanks

You'll need a Dremel and spray paint. For the Dremel, you'll need a bit that can handle dremeling hard metal. What I did was find the wastegate. Spray the area with the spray paint, and then moved the flap over. then I took the dremel out and removed "MOST" of the white. You want to be careful because if you get too close, the flap might not cover the hole well, and you won't be able to boost as quickly.

This procedure was done on my FC. I'm sure the procedure is the same on an FD though

It's pretty easy to do. Aside from a frozen bolt, took about 5 hours start to finish. Y'gotta separate the turbos, and grind the hell out of the wastegate hole. I could've standed to be more agressive, but i now never creep more than 1 lb through the whole powerband. I got a 'Rotary Grinder' from Sears for about 70 bucks and a few carbide deburring bits and went to town. Have fun.

Try to contact Bryan at BNR Supercars.
His website is www.bnrsupercars.com
He is very good, and good customer service too.
Tell him that I sent you.

The porting he did to my turbo, gave me 2 psi lower on secondary. So you need boost controller to bring it up. But this is better than having boost creep, then blow your engine.

I know about Brian but I don't really want to spend too much money to do this and now that I know what to do, I will probably do it myself unless.....Scott you got the hook ups?
