Default What Injector?
Trying to figure what Injector to go with. I am currently running stock shortblock with PRC LS6 heads and MS4 cam. LS6 intake and stock injectors and rails. During my tune I was held back by the injectors and made 432 wheel hp. I'm changing the setup to PRC 227 heads a FAST 92 intake and UMI 92 TB Speed Inc fuel rails and plan to eventually spray a 150 wet shot. Trying to figure out what injector to go with. I was looking at FAST 36's but would hate to be limited by injectors again but to step up to a FAST 42 is like another 3-400 bucks. So just asking some opinions on what would be good for my setup. Hope to be atleast in the 480 wheel hp after the changes. Thanks

You need to look into 42 lb injectors.http://www.corvetteinjectors.com/calculator.html Use this to calculate your injector needs.

Either get your injectors from us or from the corvette link above. You won't find someone better in the industry than the fuel injector connection guys!!!

Downtime is no big deal as there is snow on the ground. Interested in this resizing though. What do you mean by 4 bar?

42# injectors would probably be the best for your setup. I have never heard of having the factory ones resized but that is a pretty good price if it works.
