I know that there has been a lot of discussion on this topic but I needed a definetive answer. I have the stock TB on my turbo'd 96 GS. I have a spare stock throttle body. I found this service on ebay.

and just wanted to see if it was worth it.

i have read all about boring the tb to bigger diameters 55 vs 60
but for 40 bucks will i notice a difference with just taking out the taper inside the stock one.

finally what is the largest i can go on the tb and not have to do any serious work on the intake

you'll notice a difference for about 1 day....

You are somebody special Tim, you matter! - from the admins (but nobody likes you, because your username is just like that other guy's, and you whine a lot)

I'm selling a billet aluminum 60mm TB and ported/polished intake manifold in the for sale section of this site. You should check into it.
