60-lb inj's / 72-lb inj's
171.99 / 199.99

kind of thinking about just gettin the 72's and callin it a day just because i dont ever feel like having to upgrade injectors ever again. lol

pros/cons.... let me know what you guys think of both

 

Unless you have really big plans, the 60's should be just fine.

 

like XM15 said, unless u have a big build in plan, 60lbs will do. even with what is in my sig 60's r more then enough. If u r planning on doing what im doing...ie smaller pulley on the tvs, engine internals...the whole 9 yards....get 60's with a return style fuel system, it helps the pistons out...better then just getting 72's

 

see thats the thing. i do have plans for it.. but it wont be finished til next year. (built bottom end and ported everything.) lol i just wasnt sure what kind of boost you could throw at the 60's and not run lean.

thats more like the response i want to see lol details are good!

 

if your going big get the 72 s . right now you will have a little idle surge now and again but it is something you can deal with.

 

from what i read is the 4th piston starves for fuel...reason why it blows first. 60lb injectors + Return Style Fuel System helps even out the fuel for all 4 pistons...so the 4th one will get just as much fuel as the other 3. It also sends the fuel back to keep cool. Probably does more but im still learning about it. But with that set up its better/safer then running 79lb injectors. I still dont know how far u can push it and what the IDC will be but i know it will be alot safer on the 4th piston and thats all i care about right now.

 

Oh, ok. Well, I know that my friend is running 325whp / 325wtq on 60's with room to go. That is on a turbo though.

 

hmm. as far as the "return style" are there any links on here that i could get a little more info on it?

and idle surge... i already have it just runnin the 42's.. but that im sure is vaccum issues.

 

im still looking for a decent thread with info. Just do a search either on the forums or on google. All i can find at the moment is bits and pieces of info. Nothing solid. Basically what i gatherd is the fuel rail pushes the fuel through the rail and into the injectors...it will reach the end and come back causes un-equal amount of fuel going into the 4 injectors. The return system allows the fuel to reach the end of the fuel rail and puts the fuel back in the gas tank (correct me if im wrong people, im still learning here). Which allows equal amount of fuel to go into the injectors for even presure/IDC...making the 4th piston work easier and happier
