I don't want to go too crazy as I will be driving it daily......should I stick with a smaller street port or can I go for a larger street port while using stick injectors, ecu, etc...

 

mine with a stock port motor, is at the limit of the fuel system, if you port it its gonna run out of fuel at like 6000rpms, so you wont be able to get into your new power band.

thank you....

 

add fuel first

is there a way to do that without running another ecu/standalone.....like upgrading injectors/fuel pump/size of ful lines, etc.?

 

Hmmmm. Very interesting. Unless you guys mean turbo rotaries, I thought the consensus was the stock 460's were fine on na engines. Usually we S4 guys have to lean out the upper fuel curve?

 

YEa, I agree with 88. From what I hear, even with a large streetport, the stock 460's will be fine. I have heard of some upgrading the secondaries but for what point? You shouldn't ned that much fuel for an NA streetport. Maybe if its a bridge or something.

 

hmm you have a point, i was thinking 84-85 gsl-se witch is 2x 680cc injectors, it runs out of fuel with an exhaust.



if its an 88 se, port away you have enough fuel to make almost 200hp....
