FWIW, I ported my own TB. Can't afford a Fastman or F&B. I picked up one from the junkyard through car-part.com. Came with all sensors and a throttle bracket. I ground off and polished what I could. I will post the pics and such tonight when I get home. I noticed a change in power and throttle response. Eventually I will get an F&B, but that is pretty far down the road. Cost wise I think this was a good compromise.
