Question type: Car Customization

i have been thinkng of upgrading my 19 lb injectors to 24 lb injectors. can i still use the stock rail or do i need to upgrade. also do i need to change the fuel pump to a larger unit or just put on an aftermarket one that goes to the line instead of in the tank.

Personally i would upgrade the rail... but it likely doesnt require it... Its getting on in age if its a stock one and could use the refresh im sure anyways... Your stock fuel pump should be fine but i always overdo things ... what are your further plans for the car??? the ken bell boost a pump is a great easy solution btw... i recommend them anytime... especially as the ford GT pumps im running are expensive and hard to come by... so in short yeah id upgrade all of it if your planning on upgrading your car... if your just upgrading the injectors for fun may i ask ummm why? haha... do a through job not a partial u kno?

i am planning on upgrading the injectors to 24 for the summer. i plan on upgrading the lower and upper intake manifold and the throttle body to a 75 mm with egr. in about two years i would like to supercharge it. but i am only planning a 5 or 6 psi one. i am just looking for some changes that i could make without braking the bank or getting my insurance cancelled

ok zac... well then if your planning on supercharging later then you might as well go all-out and do it now... when u supercharge your gonna have to go to 45 or 60lb injectors and that is definetally gonna require pumps and a updated rail... so you might as well get the supporting hardware done... or put it all off untill your ready to do the whole thing... there have been good results with a full intake and exhaust (headers too...) if you can i would leave the heads and cams untill you charge its gonna be expensive if you do it twice... ultimately if your gonna do the lower end and build the engine your gonna be doing a cam head swap anyways so just make sure that you dont end up buying expensive parts twice... I myself have 42lb injectors in my stang with plans to build a 400hp NA setup... so i have twin Ford GT pumps in my tank (they make so much noise when the car is running...) i also have a updated rail, lines, and of course a ecu tune designed for them... im running a updated but not the PI head from ford and a stage 2 comp cam... im netting 260RWHP and about 335 crank i guess... i assume you have the driveline issues figured out yes? once your making supercharged power your gonna need a beefed up tranny, driveshaft and rear end... fun fun fun eh hahahaha... You should be ok with the stock rail untill you go to the bigger upgrades but there not a big deal to swap up anyways... i would do the pumps now though...

i am planning on only making around 300 horse tops. its my first mustang but i always wanted a 69 boss 302, but since i have the engine i figured i would get the most use out of it. the intake is getting done this summer, but i have ceramic headers on it with a bbk crossover pipe to flowmaster set up after the cats. but i am planning on making more a show car while still having really good performance. but i cant break the bank and i still want to have pretty decent gas mileage cause i have to commute between campus and work

well you gotta remember that if your gonna SC then your gonna need the bigger injectors and those things EAT fuel like CRAZY... you can expect your mileage to go down about 30% at least... i dunno 300 hp isnt out out of the realm of possiblity for a NA setup either... and it would be pretty badass too ... i would look into (the fuel system bc u need it anyways ..) a set of high flow heads, a stage 2 or 3 cam (sheel be rough but hell thats sweet too...) and the full intake system you might be able to optimize it for 300-350hp without too much trouble... i dunno though it would be a risky venture either way i suppose..
