Racetronix makes good injectors. I would do a little searching about the size injectors per boost. At first thought, I would probably go with 60's, it will give you room to grow.
Good luck.
Good luck.

so many different choices it is hard to decide i did the rc enginering and it said 40.59lbs/hr so not sure if my 32# will do the trick and that rating from them was at 500 hp and if you maxed your 48 out at 460rwhp still not sure on this

Excellent comment.... you would not believe how many people I try to help with respect to future upgrades & often I'm told "I'm not changing anything else after I get this together". Then a year later I get another call asking about an upgrade. This has held true in relation to injectors, fuel systems & superchargers.
The 60's are easy to tune & will serve you well into the 800+rwhp range.
As far as Racetronix, their products are of very high quality & I would be glad to help you out with anything you may need.

the problem with 60#ers is below a certain range or if you don't have a fuel pressure regulator.. then you idle at 11:1 AFR RICH AS CRAP. so if you don't plan on changing up to 800hp you don't need them
48# or even 55# injectors from racetronix will serve your purpose much better and even if you do build a 427 twin turbo setup and pass 800HP someone will buy those injectors off of your hands for practically what you paid for them. and you can then upgrade.
