Default Throttle Body

I'm trying to research a performance throttle body for my 01 Cruiser, but so far all I've found are dead-ends. Anyone know something I don't? Thanks!

You could get it bored out. I've never seen an aftermarket tb offered for the na PT.

Any ideas on where to get that done? I'm in Idaho, and sadly, the Cruiser is not all that big here. So parts and the like are hard to find.

Got any performance shops around? They ought to know a good machine shop that specializes in machining car parts.

I wouldn't bother with it, I believe it is a 55 mm bore. there have been performance tests that indicate no improvement with a 65 mm bore.

Maybe not on the na PT. but a definite improvement on the turbo model. I'm pretty sure the stock tb is 52 mm. I've got a 55 mm tb from DCR (Darrell Cox Racing) on my '05 SRT-4 and there is definite throttle improvement. The 65 mm tb is overkill unless you go big turbo. 65 mm tb on a na PT would be a joke.

BUT, the originator of the question has an 01 PT so unless he added a Turbo (which he should have mentioned) the bored out TB won't do any good as Ironman pointed out.

I looked into a bored out TB for my Vette and like the PT, unless there are other improvements or upgrades (like the turbo) that can use the added inflow, adding the bored out TB doesn't do any good.

Ironman wasn't specific about turbo or non turbo. Just a blanket statement that really only applies to the non turbo. Personally, I wouldn't waste my money trying to get more out of the non turbo PT. You'll spend a lot of money for a limited increase in power.
