Hey Guys, I was at the track on the weekend, and some guys came up to to me offering me a 94-95 cobra upper and lower intake, 70mm throttle body, and 24 lbs, injectors all for $400 bucks. I have a 94 5.0 with off road x-pipe, magnaflows and cutouts. Motor wise i have all new ignition, cold air intake, underdrive pullies. Would this be a good upgrade from the stock intake. what kind of gains should i expect? thanks guys.
Its a nice deal, but dont install the injectors yet, you need a chip to recalibrate the EEC.
The intake and TB is probably worth 20hp. With a good set of heads, that can go up another 40hp.
Then you can install the 24 lb injectors and tune with a chip.
There is really no need for a chip. You can install the 24lbs injectors by buying a matching cobra mass air sensor (calibrated for 24lbs injectors) or a Pro-M meter calibrated the same. Thats a little easier and cheaper to obtain then a chip! If you dont plan on going much bigger as far as heads are concerned i would by the intake, it will provide a little bit better flow, but you probably wont feel too much of a difference. If you dont want to install it I would at least buy that stuff and sell it, as its a pretty good price. I know for a fact you could sell the injectors for over 100$ and the intake for about twice that if not more.

The COBRA MAF IS NOT calibrated the 24s, that is totaly wrong.
The EEC controls the injector size, "calibrated" Mafs such as C&L and PRO-M just "fool" the EEC.
What actually happens with calibrated MAFS is that their circuits are modified (pro-m) to send a lower voltage to the EEC, the EEC then responds by opening the larger injectors with a shorter pulse, thats why they work...BUT by using "calibrated" mafs you are doing it the wrong way, and it will affect air fuel ratio (would end up LEAN OR RICH).
Calibrated MAFs appeared when there was no way to reprogram the EEC, to this day they are still used, and they work, but it is not the best way to do it.
The correct way to "calibrate" for larger injectors is to reflash the EEC or use a chip.
I remember hearing somewhere that the cobra MAS reads like the GT's 19# calibrated MAS and then the computer in the cobra converts it to the nessecary 24# injector reading for the cobra! Someone can else may know for sure. But I do know just buying a cobra MAF will not work for calibrating a car for 24's. Heck its just an aluminum housing, it has got to do with the electronics.
But for $400 scoop that stuff up! Just make sure the injectors are low miles and all work properly, but even then that ain't a bad deal...at least I don't think

94 Cobra Intake Question?
