Agreed!Rick 91GT said:24# will be fine, I'd go with a shorty 80mm, not the BULLET 75mm.
Funanin said:go with the ford motorsport cobra kit that comes with a 93 cobra ECU, 24# injectors, and a 70MM mass air meter. They are all calibrated to work together and with the right combo, they really do make some power. oh yea, the stock fuel pump on 86-89 is 88 lph, the stock on 90-93 is 95 lph, which is no where near enough fuel for a combo like that. I would go with the FMS 190 lph because it is the whole fuel pump contraption not just the pump itself. (alot easier to install and replaces everything surrounding the pump as well)
Rick 91GT said:I would not reccomend that kit to anyone, the Cobra computer is terrible, pulls timing and is less aggressive then the other factory computers.
I would go 155lph minimum, the 190lph-255lph would be a better choice depending on your future plans. I think I still have a Ford Motorsport 190lph pump with a complete new install kit, less then 5000miles if your interested $75 shipped. Quietest HV pump I have ever had or installed...
Yes the car will run on the stock pump but may run out of volume in the upper rpm range, which is not a good thing....starving it for fuel can cause major issues.
1990LXDropTop said:Hmmm, so what if I just took it easy and shifted at low RPMs until I get a better pump? Also, how involved is it to replace the pump? It is something I can install easily in my garage with just a pair of jack stands, and basic hand tools?
Grn92LX said:If you can do a camswap on your own you certainly can do a pump swap. Its best to do when the tank is low. I use 2 jacks (I always remove/install my gas tank when im alone)One jack to jack the car up and one to support the tank once its loose to lower it and raise it. I woud go straight to a 255 and a new fuel filter while your there. I would also do 30lb injectors toleave more room for growth down the road. I had to swap in 30's because my 24's were too lean even at 300rwhp. Though, im sure if I had my PMS back then I coulda fixed that.
