I can recommend a lot of parts too, but the fact is that the larger the injector the less atomization of fuel and the worse it burns. Fuel lights up when it's a mist aka atomization. You always want the "right" size injector so that you have enough without going lean and running out of fuel, and yet..you don't want anything too large.

I saw the ClubGP thread too. Some of the same suggestions I gave you and a few different ones. When one guy says "do this" and 5 other people don't. It kinda makes you wonder what the reasoning is for the minority. I'm all for getting as much advice and knowledge as possible before buying and building and like how you approached it. When one guy says something different, ask for the reasoning. It might be better than the other 4-5 folks.
