Ok I am doing this swap. I am sending the rail to Garfinkle to have it milled down. I purchased used 850s. Absolutely by no stretch of the imagination am I an expert on injectors but these things look pretty much brand new to me. They show no signs of wear that I can see. I've read that you should buy a few new parts, including o-rings from malloy just to be safe. For some reason I am getting lazy and don't feel like doing this. I am thinking about just installing them the way they are once I get my rail back. If these injectors needed parts replaced would I be able to tell that by looking at them or not? Am I really playing with fire installing them the way they are? Thanks

 

Send the rail and injectors with the o-rings to Gar . He will inspect them and install then with the lub made for o-rings . He may have some new o-rings also .

 

agreed, and it doesnt cost much to test the flow on them. Well worth it to have them checked and rest easy.

p.s. Dont expect to go push over 360rwhp on 850's like some say. I maxed mine out pretty easily as did a stock twin seq. owner.

 

I have 1300 secondaries...I'm hoping to be able to push a little more than 360. I did maxcoopers fuel calculator and my fuel was good for high 4s or over 500 at 85% duty...can't remember exactly but it was good for what I'm planning. I'm shooting for 430-450.
duboiser...that sounds like a plan to me. thanks
