throttle body upgrade

[ryan99]

how does this affect performance/increase HP???will they fit regular aftermarket CAI???found some topics in the forums which suggest to upgrade it but never mentioned how it affects performance.(larger throttle bore,larger air going in???)

You have to upgrade to a larger intake manifold as well, or the upgraded throttlebody will just be a waste of time and money

The only thing that changes on these is the inner bore and butterfly size. The outter portion will be the exact same as it was before and your old intake will still fit and so will your stock intake manifold. Just don't be looking for some Big # gains out of this. From what i've heard, you pick up some more tq as your car can breathe a little quicker.

Without spending some REAL money, those 2 are going to be the biggest help getting air into the engine. They just make it more efficient and get the air the engine needs quicker. Next you can P&P the head for some nice gains. Other than those, forced induction is the only other way your going to get air in there faster.

excuse my ignorance... P&P?

[Lances133]

Ported & polished

and juss for kicks and giggles... how much would that be?

[millrtime]

A bit more than that actually. I was quoted around $700 from 2 different places. For a P&P with a 5 angle valve job. Install new valves and guides,springs and retainers and roller rockers.

owwy...

[Classicrocjunkie]

err.. as for a gain. If you were to do exactly what i had listed... Your car would become extremly peppy if ya know what i mean. Roller rockers alone are dyno proven 8hp gain



I <3 Crane products.

Ive been quoted from $700-900 for a P&P. Its worth it for N/A and even more so with boost. Ive seen it do night and day wonders with a nice turbo setup granted it was on an evo and not a cavi but night and day I tells ya.

[notaricajustfasta]

what excatly are the steps in P&P? Is it the entire intake setup or is it only the intake manifold and adacent areas?
