Injectors?
Im looking at either 880cc or 1000cc injectors. Im not sure which ones to get. I have a few mods(to include a stroker and a 35r very shortly) and dont know which to get. Any recommendations? Thanks!

1000cc.. Or perhaps (if it's possible) a dual injector setup ie. primary and secondary injectors.
You have to also take into account the fuel system. I'm not real familiar with EVO's but I know on honda's the actual fuel supply line becomes a restriction at 650ish hp.

600whp. I was looking into the AEM ems. That is probably what I will end up getting, almost everyone that has it has nothing but good things to say about it.

1000cc or 1200cc, especially with EMS you will be fine. Its always better to go bigger then smaller. Im buying 1000cc's to fuel my SCM61 on my 1g and thats just with a EPROM chip

Re: Injectors?
They have a calculator available. Enter the values requested for BSFC for a turbo, on the high and low end, horsepower estimates on the high and low end of what you expect, and the base fuel pressure you intend to use.
That will give you a good sizing to start with. If you need a little more, you can up the pressure a bit, or if you need a little less, you can lower it a bit. It gives you a good margin. I'd use the recommended 43 psi as a base. Up to 70 is usually okay for a fuel system. Below 30 is not recommended.
Properly sizing the injectors is a key to making good, safe power. Doing so, with a margin to go either way, is just smart. And RC Engineering is a good source of information, as they build the injectors for a living.
