I've got a 92 GT with an F303 cam, stock heads except springs,stock intake, mass air, stock injectors, Mac equal headers, off road H pipe.Should i go w/ bigger mass air and injectors? Dont have a whole lot of money to do this with, any suggestions on how to get a bigger bang?

A bigger bang would be to get a new set of gears. You do not need new injectors until you hit around 300hp.

+1, worry about injectors when you upgrade the heads

Agreed. If you're going injectors, you'd want to do MAF, throttle body, and preferably inatke and heads.
You also might want to consider some stiffening upgrades, subframe connectors, strut tower, etc. if you're planning on getting power to the ground.

Did you do the cam? If so, I'd be curious why this was your first engine mod?

I would put an intake, throttle body and bigger mass air on to open up the intake some more. This will give you a big hp gains cause you allready have a cam.

great post,

id have to agree with the guys that say stock injectors will do just fine with your current set up

P.S.I.cho

+1 to above posts

these cars are stock at 19# injectors wich is plenty of fuel untill 300hp, get some gears and heads atleast before you consider upgrading

Yes I did the cam. I thought the mass air (stock) and the throttle body and intake were enough to support the cam with good HP gains and a good sound. I've had some problems gettint every thing right.Sometimes it idles good sometimes not, sometimes it feels like it has more or less HP than other times(slugish). Sensors maybe? At first it would backfire alot but it finaly quit . Still stumped
