Would 42# injectors be good for 22#s of boost? I was going to get 42s but i would rather be done with the injectors now than have to buy new ones later when i get to 600+ hp later.
It really doesn't matter, as 22lbs of boost will scatter your stock block all over the street anyway. I'd really like to know who this "everyone" is that's telling you to skip the 42's and go with 60's? Because it seems most here (the guys who actually own and drive these cars) are telling you to stay with the 42's. Are the ones steering you towards the 60's by chance import car owners?
I really urge you to send back those injectors and pick yourself up a set of 42's and matching MAF. Like I posted above....the 42's will comfortably handly over 550hp...which is more horsepower than your stock block will be able to handle. Not only that, but they'll keep your budget "honest" and steer your towards a more realistic goal. Otherwise, you'd better set aside a pile of money for custom fuel lines and rails while you're at it, because the stock ones sign off right about the same time the stock block does. Better put aside another grand or so for ignition upgrade, because you'll never light 22psi with the stock ignition set up. Damn....I hope you've got at least another $5-$7K to spend on the drivetrain. What, you didn't think you'd be able to transfer 600hp through the stock T5 and rear end did you? Crap....you're already $10K in and you haven't even built the engine yet. Don't let your desire, overshadow your common sense. When you get into built block, big blower and supporting mods territory, you'll be in $15-$20K or better, before you know it?
I've got to ask.....what's the fascination with throwing around figures like "22lbs of boost", or "600hp+"? Do you realize how fast a car with that much power is? Have you ever gone that fast? Don't take this the wrong way, but if you've got to ask, you probably shouldn't even bother. If I had a nickel for every guy I heard quote massive projected horsepower figures only to never come anywhere close to those numbers, I'd be a very rich man. Most end up for settling far less after then find out what's actually involved (cost and work wise), or worse yet losing interest in the project or running out of money and having to sell the vehicle at a loss later on down the road to finance something else.
My advice is, that if you don't have the money put aside to finance this project right now and/or a second car to drive in the mean time, don't even get into it. You'll end up with a car sitting on jack stands for the next 3-years and a vacuum in your wallet sucking out every penny. And it would be a shame to see you waste years of your life and thousands of dollars on a car you'll probably never drive because you got in over your head.
