What should I do?
I've still got the 22R-E but its shot and need a new engine,
Thanks to you guys i've decided on the 18R-G. But I'm not too sure on which one i should get, 18r-geu or 18r-g.
Whats better or has more potential for power?

For a street engine, you can't beat EFI. The twin-carb version is actually fairly limited in power output unless you replace the carbs. Try pricing a new pair of Webers and you'll forget that idea pretty quickly!

better potential is always with efi. more fuel pressure (so you have less fueling hassles to getting big power) plus much easier to turbo.
having said that, I recall a guy with a nitrous sucking V8 that was carbied.

I think you'll find there's been MANY V8's (and other engines!) with carbs and nitrous 
I'd go the EFI personally, especially if you want to go up with the cams a bit - carbs can tend to be terribly thirsty on a done up engine (I realise they don't always HAVE to be - but they seem to nearly always engine up that way!). For smooth running, easy starting and economy, EFI every time.

FWIW my 18R-GU originally came with factory Solex's, and I later converted to factory EFI, so I have experience with both. I can't think of a single thing the carbs did better than EFI, except perhaps for the fantastic induction noise you get with sidedraughts. Having said that, the car still has a pretty good induction growl with EFI!

in a word: WEBERS .........there is no better ROAR! 
But for everyday driving, they suck (fuel), and are a bitch to have tuned properly. Also warming up the engine, babying the trottle, etc etc..... but i still love them webers!
