Professional products TB?
Professional products TB? Im looking at buying a 58mm professional products throttle body off of ebay and was wondering if anybody has had one or if you have heard anything about them and if its a good product? Also how much am I going to gain by getting a 58mm over the stock 48mm TB on a 383? Thanks

ive got one on my Z, the product is nice, but beware of one thing, the tps sensor on the side, the factory bolts for this do not screw in all the way in , if you try and force it, they will break. you will have to get different bolts, or atleast thats what i had to do
I have ran one of their 58mm tbs before, and it is a great product for the price, but like stated the stock TPS bolts are a bit too long. The finish is nice, and is easy to set the idle. The shaft has no play in it, with a firm and smooth throttle linkage.
For the TPS screws I just dremeled off a little from the tip of each bolt and didnt have any problems. I do not remember where I ordered mine from, but it was cheaper then most ebay sites(and their website). Not sure if it was a sale or not, but can check my old emails and stuff for the info if you'd like.

Goto the hardware store for them. Or if you cut yours down, find a nut that fits on it, screw it down to where you're cutting and cut it flush with the nut. Unscrewing the nut will them remove any barb left on the bolt
