Hey I was wondering what kind of gas mileage a street-ported n/a would get. I also want to know how much more gas a big street port drains compared to a mild strret-port. My engine is getting up there and when I have to go and rebuild it i would like to put a strret-port on it, if it doesn't drain too much gas.

ps- around how much power did it add to your car?

 

I believe adding larger secondaries along with the streetport may affect gas mileage slightly. Same thing with adding the chip that goes along with the streetport.

 

CHIP that goes along with the streetport??? WTH???

 

Dude you drive a sports car and you wanna port it. Who gives a **** about gas mileage? Dont take that the wrong way, Im not tryin to be offensive. Seriously, If you want gas mileage sell that sports car and get a Metro. A port will affect gas mileage, but its worth it.
