stock i called andersonfordmotorsport and i was told to put on at least 70mm and 30pounders! what sould i do?

 

[aleborjas]

help me rick?

 

[Dbeck002]

With 185s and a 306 24s will be fine unless your spinning the engine high 7k+ RPMs, then you might need bigger injectors.

 

[2002BLGT]

24s should be fine

 

[IntenseBlue]

What all did you tell them about your setup?

 

[aleborjas]

sorry i have XE274HR cam and is N/A

 

[IntenseBlue]

Did you tell them any future plans and that you already had the 30s?

 

[IntenseBlue]

It's not like they're gonna hurt. Just get an AFPR and crank down the fuel pressure. That's better for the fuel system anyways I think.

24's will be fine.

I would get 30's if you are going to get a tune.

Stock fuel pressure (38-40lbs) is what the stock computer likes to see...so you want something to keep you around that.

70mm TB.

75mm tb and 30's. Open up the typhoon inlet to 75mm unless the porter already did it when it was "stage 2" ported. What AFM told you is good info, they know how to make power. UNless you have a blower like Rick 91GT asked??

 

[aleborjas]

nop my car is N/A no power adder and i told AFM all i have and he told me to put 70mm TB and 30pounds at least on injectors...

 

[Rick 91GT]

yep 30# and a 70-75mm TB is what I would use, although you may squeek by with a 24#
