Heres the scoop. I have an 88 gt mustang drag car, gutted out. Engine: stock block, pistons and crank. 289 hi po heads (nice port and polish job). Trickflow Stage 1 camshaft. BBK cold air kit. STOCK UPPER AND LOWER INTAKE AND 58MM THROTTLE BODY! Anyway, I am planning on putting a different intake and throttle body on. I am looking towards a trickflow track heat intake and bbk 70 mm throttle body. Do I need to jump from the stock 19lb up to 24lb injectors? If so, will the stock fuel pump handle the 24lb injectors?

Thanks, Joe B.

those heads ported or not arent much better than the stock E7s...until you get that intake, which i'd do street heat considering you're not runnign good flowing heads, and only an 65mm TB...24lb injectors would be fine, not big at all and not too small..and i would do the fuel pump upgrade to an 190lph or 255lph fuel pump...also wouldnt consider that an drag car, just a stripped basic street car...

with new upper, you would benifit greatly with a fule pump upgrade, adjustable fuel pres reg and 24lbers

+1 on AFPR...forgot to mention that

The car is a drag car only, not street legal. It runs 8.10-8.15 in the 1/8th the way it sits. I forgot to mention it has 4.10 gears, locker, 26x10 MT slicks, a 3500 stall in it and I shift it manualy at 6200 (just shy of the rev limiter). Thats why I wanted the track heat (1500-6500 rpm) and not a street heat ( idle to 5500 rpm).

The car is nothing special, you can see a video of it on youtube. The link is:

My car can be seen in the close lane starting at about 1:03 till about 1:10. I believe I ran 8.89 (still had stock 2.73 gears at the time)

I doubt you'll need 24# with those heads............

change your intake and the 70mm will be good 24lbrs and 190lhp pump, if you get better heads look into a 255lhp pump, afpr makes air/fuel tuning as easy as turning a screw driver.

Doesn't the EEC4 learn around that? The o2 sensors will send the lean/rich condition and the computer will reduce/raise the injector pulse to compensate and the overall gain is nothing but a potential for the EEC4 to freak out, throw codes, or ignore things because they are out of range or fall back to a default air/fuel map which may not be the most ideal. That's the way I understood it but I could be wrong.

No you don't need 24lb injectors with that combo.
