Yeah Bill, it would take a bigger turbo and/or ported head, valve springs, intercooler, exhaust, etc, etc, to make putting a bigger throttle body on an LNF a good idea. Otherwise you'd probably do more harm than good. Hey, weren't we talking about the "bigger is better" mentality on another thread or forum?! It's hard to get guys over that idea. I know you get it.
Devinslawsby, I don't know how to say this without being mean, but if you're having a hard time finding the throttle body, please, PLEASE, don't mess with trying to port or polish it. It absolutely is not something that should be done by anyone that isn't very good at these kinds of things. You will not gain any horsepower and more than likely will cause new problems.
VERY GOOD ADVICE...NO BENEFIT UNLESS EXTENSIVE MODIFICATIONS ARE DONE FROM TOP TO BOTTOM...I ONLY SEE ALOT OF POTENTIAL DOWNSIDE TO MESSING WITH THE STOCK THROTTLE BODY.
