Which of these flow patterns would be best, the v pattern is suppose to hit the back of the valve and atomize from the heat, the second one uses smaller holes to atomize.

I'm assuming the finer atomizer would be better, but how much better as far as efficiency and tun-ability?

The v shape pattern ones i can grab for like 300, the second one i can get for around 600, do you guys think they are worth the price?

Dont bother about that, and get bosh EV14 based injectors. You can find them easily (injector dynamics, fuel injector clinic, fiveo motorsport, you name it, nearly every injector shop has one).

You can get a V shaped pattern with atomisation that looks like the second one on each spray, and that is what EV14 do. Tunability wise, you want something with low latency, and these have lower latency than average injectors with the same capacity. My current 1000cc set has a 830µs latency ... that is usually 600-700cc injector latency.

What kind of adapter do you need with the ev14s?

I dont know, i have a set on a standard fuel rail (on a CA18), i dont sell them or anything.
I know they work better than any of the 4 other injector sets i went through, so i'd recommend these anytime.

It looks like ID1000s are available on the website you linked, try emailing them to ask if they are a straight fit or not, it will be simpler.

i decided im going with the ID1000s, with an ebay fuel rail, if it leaks ill just bite the bullet and get the greddy, but for 70 bucks its worth the gamble, it either will leak or won't.
