Quick question about fuel injectors

MIGHTYJO3YOUNG · February 9th, 2008, 11:14 AM

I have a jasper motor that was supposed to come with 280 hp....since then i added upper and lower intake upgrade, equal length shorty headers, x pipe, soon to get some heads. My question is what size fuel injectors u guys think i should get? Or when should you upgrade from the stock ones? Thanks.

19 lb should support to around 320 hp, if you plan motor upgrade in the near future 24lbs

White Thunder · February 9th, 2008, 11:36 AM

go with the 24s what upper and lower did you do....

yes 24's will be a good investment

ujslost · February 9th, 2008, 11:46 AM

24s will allow room to grow and a used set can be had reasonably

That number would be at 100% duty cycle.

24# to be safe and allow some future hp growth.

another vote for 24#s

Put in a 255lph fuel pump if you havent done it as well.

MIGHTYJO3YOUNG · February 10th, 2008, 08:16 PM

New hood coming in tommorow and a stage 3 clutch kit goin in tomorow so im pretty excited!

MIGHTYJO3YOUNG · February 10th, 2008, 08:17 PM

Iwannagofast · February 10th, 2008, 08:22 PM

wat headlights did you get

MIGHTYJO3YOUNG · February 10th, 2008, 10:45 PM

Black Projector Headlights (87-93) I got these ones. i got this hood too. 1987-93 Mustang Cobra-R 2000 Heat Extraction Hood :: FiberGlass Hoods :: Hoods & Hood Accessories :: Exterior & Body :: 1979-1993 Ford Mustangs :: Ford Mustang Parts :: MCRParts.com | Muscle Car Restoration Parts i havent seen too many fox body's with this hood so i went ahead and got it.....they ended up shipping the wrong one tho so they had to take it back and send me a new one that comes in tommorow.

Tony_90fox · February 10th, 2008, 11:35 PM

yeah that hood is pretty rare on foxes. IDK why, they look great on them. I guess because alot of people like the standard cowl hoods.

yeah I would not run 19's with more than 275hp or so to be safe.. Some people will say otherwise but to be safe you dont want to lean out..

Stangzilla · February 10th, 2008, 11:50 PM

Also If you are gonna go to 24lb injectors I would put at least a 190lph fuel pump in the tank also.

MIGHTYJO3YOUNG · February 11th, 2008, 01:58 AM

will the car not run right with the 24's without the 190 fuel pump?

nitrouskid · February 11th, 2008, 02:54 AM

i didnt have a problem running the 24s with the stock pump i just thought i have the bigger injectors so i should get the pump to back it up so i ended up running the in tank 255
