I want to know is it benefial to get a port and polished on Supras. Where do Supra guys go for a good p-n-p?

How much whp/wtq will a good p-n-p provide?

Thanx,

think about it, more air flow, means more fuel, bigger bang faster spool. any performance shop can really do a port and polish for you, but ask around and see which place seems to do it the best.

give or take for my car it added probly 10 rwhp on a NA supra. id say it would add about the same on a tt maby more becaus of the air flow depending on what mods you have on the car.

remember on the turbo cars that the bigger the pipe the more pressure loss will occur (more volume it will take to fill the space) so you cant go nuts with larger piping unless you upgrade everything else to handle the volume increase.
