performance upgrades
 

I've got a 1984 Mustang with a 1994/95 5.0 and 1991 intakes/throttle body/mass air. The engine remains stock. I have upgraded to an 8.8 rear end with 3.73s, added h-pipe and flowmasters, added underdrive pulleys, k&n filter, 155 gph fuel pump and adjustable fuel regulator. My AOD is shift kitted and built to handle up to 500 hp. I am thinking of upgrading to a E303 cam, trick flow idle to 5500 rpm intakes, 75mm throttle body, 75 mm mass air, and cold air intake kit. Does anyone think I need to upgrade injectors? Does this sound like a good combo to add? What kind of horsepower increases can I expect? I'm probably going to go with 75mm on the throttle body and mass air because that's what the intakes are designed for. Any ideas, suggestions, or advice would be much appreciated.

:feedback: :headbang:

I've changed my mind on the trick flow intakes. I got a like new polished 70mm throttle body and original 93 cobra intake (which flows better than the new ford racing cobra intakes). I can always rework the intakes to get more top end. I'm sticking with the E303 cam. I've chosen the 76mm c&l mass air. I also snagged a set of GT40 Turbo Swirl aluminum heads. These heads would allow me to go with a much bigger cam, but I wanted to keep decent "daily driver" driveablility, and since I live in california, wanted to stick with emissions legal upgrades. I will repost once I get all of this installed and let anybody interested how much of an improvement I got. I'm expecting 75-100 hp from it, which would put me in the 325-350 range...not too bad for my light 84!

If anyone's interested, here are the final upgrades I decided on...

GT-40X Turbo Swirl Aluminum Heads
1.6 Roller Rockers
E-303 Cam
30# Injectors
Ford Racing Cobra Intakes with phenolic spacer
76mm C&L Mass Air kit
70mm Throttle Body
MAC 1 5/8 shorty headers

You guessed it...HUGE improvement. My next upgrade will definitely be tires. I'm getting pretty good with the throttle though so I don't overwhelm the tires. I haven't yet taken it to the track to see any 1/4 mile times, but considering how light my car is (1984 LX), I wouldn't be surprised to see some low to mid 13s. I'm pretty surprised at how loud it is, even with a catted h-pipe and 3chamber flowmasters. Anyway, I'm very happy with the performance and pleasantly surprised how much that E303 lopes! :headbang:

sounds like it should a nice street car and run good

no pics ? :(
