I have a 94 mustang Gt and im about to drop a new engine into it. Its a stock 5 litre engine with hyperutectic pistons, and i just intalled an E303 cam into it. I was just curious to what would be the best intake manifold, and best fuel injector size to throw on this new engine? Any replies would be appreciated.

keep the stock injectors. they are good to about 275 rwhp.

there are lots of intake to choose from, but pick one the operates in the 1000-6000 rpm range.

Trick Flow track heat...or a rpm II would both be great intakes...and as stated above your a good little ways from needing bigger injectors..

Thanks alot! I was a little iffy on if i should go from 19 to 24 pound fuel injectors.

What are your plans/mods for it? I 2nd the Track heat....that's what I'll be using next. You've got a ways to go before you out grow those 19's....

well, i have the cold air intake, 65mm TB already, but i know that if i get a Track heat, then im gonna want to go with a 75mm TB, so i didnt know, i thought that since im bringing in more air, that i would need more fuel. I want at least run a 13 flat or high 12's quarter mile. I have bbk headers, x-pipe, flows, and a 3:73 gear. I just want to know what i should put on this brand new engine, before i drop it in.

If you want 24lb injectors, Ill sell you mine, They are less than 2 months old, with less that 500 Miles on them.

Im getting 42s so I wont be needing them, ill also throw in a Calibration tube.

You don't need the 75mm tb since that would way overkill for that tame of a motor...and you really do not need the 24's.

Is your MAF stock? If so, a bigger TB won't do jack for you. You could get a 100mm TB (hypothetically), but the restriction is still at your 55mm stock MAF. Go w/ Pro-M (now PMAS) or C&L and you'll notice a difference w/ that mod alone.

so i should go for the Trick Flow intake, keep the 19# pound fuel injectors, and save up for some nice aluminum heads.

Yes, my MAF is stock, but if i was going to get new injectors, then i would have gotten a new MAF. what size MAF should i get with my stock injectors.

P.S. when i get the Trick flow intake, i know that i need the throttle adapter, but will i need a new EGR adapter fitting and strut tower brace for my 94 stang
