Porting internal wastegate/turbine on Stock IHI, need direction...
Hey, Thanks to this site I found a good deal on a Stock Mazdaspeed miata IHI turbo with the compressor upgrade, and was wondering if anyone has some experience with mild port working on turbos. Deadbolt wants about 350 plus shipping, and I'd rather do it myself... I have asked a few MSM guys on our forum, but there is far more experience here, and many more tuners. Well, basically I'd like to smooth out the exhaust side and clean up the wg where the downpipe bolts up, on the IHI it apparently flows horribly. Any tips? also, I have a die grinder and a lot of bits/paper to use. anyway, thanks a lot!

I could ramble off numbers but its much easier to just look at the shadow and machined surface for the flapper then actually measure anything.
Here are some threads about it.
