Ok so today i got my hands on some 450cc injectors from a turbo 2.0 eclipse engine... well the car turned on fine and idled fine .. i used the 10ohm 10 watt resitors ...but it kept braking up at high RPM'S.. my question is if i get a fuel pressure regulator and lower the pressure a lil bit will that fix the problem?

I doubt that will fix your issue..

You need some kind of engine management to turn the fuel down in the 450cc injectors.. such as chipped ecu (crome, etc) old school vafc hack, etc

 

Also i just noticed topic title.. ''stock LS''

If it's not boosted.. why are you running/wanting to run dsm 450cc injectors?

 

Well now im spittin fireballs lol.. But yea i kno only cars that are boosted use those injectors but if i can turn the fuel down a lil bit i kno i can gain more power out of my ls.. i have a sleeved block with cp pistons 12.6:1 compression that i willl be putting in my car in a few weeks but i was just trying out those injectors and i am going to get it tuned because tuned LS is a beast ...talkin from experience and no its not completly stock.. i just meant non turbo

 

lowering fuel pressure wont cut it for you.

 

You need a good EMS to run those. You can't honestly expect to just throw a set of 440s in and have it run...

Secondly, there is NO point for you to run those injectors on your stock LS. That's just obsurd. But i guess you'll do what you want.

 

440s in an LS?

 

check my setup.. Im still running stock injectors.. Im going to pass smog and throw in my hondata

dude who the hell lied to you and told you larger injectors on a stock engine will help power? if anything running on the factory duty cycle on the stock injectors will cause damage internally.
