Hey guys got a couple questions here. I'm new to the motor building thing. I have my 302 it's got ford x heads with a f303 cam. Typhoon intake.
My question is I wanna put a turbo on it next year. But I want to drive it before hand. What size injectors should I put in it N/A? Can I put bigger injectors in it like 30 or 42's now or will it hurt me? Also will the factory 19's be enough for the motor now? Any help would be appreciated.

I had my car tuned by lidio and I daily drive a car with with a similar setup to what you listed without a turbo and I use 42lb injectors.He told me they weren't holding the car back at all. The way he explained it to me was that the boosted cars ( ex. lightning & cobra) are pretty much n/a until you get on it. They still have to idle, cold start and part throttle like normal. So I think you would be fine as long as it is tuned.

But its just advice
 
U can run 42lb injectors na with a tune but it will run way to rich without a tune. 19Lb should hold 300HP na if your going turbo u might want to run 60lb injectors.
 
I had 30#s in my car while I was waiting for it to get tuned. I had a Vortech on there, stock heads at the time, and all top-end induction was aftermarket. Idle was garbage due to being rich, but once I was moving it was OK. I wouldn't recommend it for too long, personally. I only drove mine to the shop for the tune. I think a set of 42# would probably drown you out completely from the get-go.

edit: if you get a tune as stated above, that will help. Or if you can fanagle an FMU in place to help curb the fuel delivery for the time being, that could be almost as good. I'd just leave the stock injectors in and put the big ones in later. Besides, you'd have to get a new MAF sensor for the bigger injectors so why bother at this point...

If you're doing a turbo installation later, what's a couple extra minutes for the new injectors?
 
if your going turbo later, get a wide band gauge now. run the stock injectors and keep an eye on your wideband. dont worry about running a little lean at idle on the gauge, just watch it when you get above 1500 and if it stays green or close to green run your stock stuff for now, whats the worst case senerio? you gotta take the upper intake off and throw some injectors at it and a mas air after?

i mean honestly though, you can pick up a set of 24's for cheep (think i saw a set for sale on her the other day for 50$) but you will need to buy a new mass air meter. id say stick with pro m.


p.s.....if you get a pro m mass air meter, you can send it back when you get your new injectors and have it re calibrated for 100$. just make sure you get a blow through mass air meter so you wont have to buy a new one when you turbo.
 
Thanks for all the info guys!! I'll keep all that in mind.
If I putted motor together now with all the stock fuel parts do I absolutely need it tuned? I know it's better but will it hurt me?

id say keep an eye on the wideband, or install new plugs, pull spark plugs after a few miles and look at color to verify if your running lean (white or very light brown), running safe (light brown-darker brown) or rich which i highly doubt (darker brown to black). post up pictues and someone will tell you whats up.
