Help me figure out my combo

91Mustang GT · June 24th, 2011, 10:45 PM

I'm buying a Cobra Intake for 200, GT-40p heads 300, TF stage 1 cam 120, what supporting mods do I need? I have BBK shorty headers, BBK O/R H-pipe 4.10 gears and a clutch fan out of a 93 cobra (Don't know if this helps but I'll take it), and 10.5 inch wide tires on 10 hole shitty wheels.

I don't think you need any other mods.

Dont I need injectors and a maf or something?

ghostrider05 · June 25th, 2011, 11:47 AM

I would think if you're using the MAF you have with the injectors, and you're not upgrading the throttle body or porting out the intake, you should be ok.... my thought is if you're not doing anything to upgrade the airflow, you shouldn't need to upgrade the fuel flow. Any of the more experienced guys wanna chime in?

i would put in a 255 ho fuel pump (255 is overkill but do it once) 24# injectors, a matching maf, bigger throttle body, if those heads have been around the block then replace the valve springs, some 1.7rr would be a nice touch too

there is no point in putting on new heads and intake if your still choked by the stock maf and tb

Everything 91cobra said + adjustable fuel pressure regulator, and underdrive pullies are cheap couple horses

If your confident in you work and take 91's advice and do all other air flow up greases do a little back yard port gasket match the head it makes a difference
