1995GT5.0T5

Stock 1995 Gt..
Im puting Gt40 Heads, 94 - 95 OEM Cobra upper and lower intake, and a B303 cam on here in the next week or two.
Are my stock 19# injectors enough? or will it be too lean? do I have to go to 24#ers or am i safe?
I also have a 255lph fuel pump i need to put in but i havent gotten around to buying an adj. reg.

Thanks, kenny

If you got the dough, get the 24lb injectors.

More room to play with...

19 will support up to 300 hp and you should be fine but wouldn't hurt to add 24's..but more important..I would for go the b-cam and pick a steeda #19 cam for your car so idle issues won't be a concern otherwise expect to get a dyno tune to tune idle.....the steeda #19 was designed specifically for sn-95 stangs and their oversensitive ecm's

not to hack your thread...[/align][/align]but im doing a similar set up of gt-40s, tubular gt-40 intake(lower ported), and a trickflow stg 1 cam or steeda #19 cam.... but I will also be spraying a 100hp Zex dry shot...[/align]so if I am looking to see 280-300rwhp on motor....am I gonna need 24lb injetors since i'll be spraying an additional 100 shot?[/align]btw, I already have a 190lph pump in the tank i just put in.[/align]

if your spraying a dry kit them up the injectors and add a adjustable regulator so you can up it during a run

ya i plan on getting a bbk adjustable fuel pressure regulator... so i guess all look for some 24lb now too....the to do list never ends lol

I would go for the 24s, you would be getting close to maxing out the 19s and it certainly won't hurt anything, not experienced with the 95s but won't you need a mass air calibrated for 24s?

mjr46

yes, you need one !!!

That engine can make more than 300 hp at the engine.
