I've read the first 3 posts with info. All have one thing in common:

Large Injectors, and an overkill fuel pump....

 

alot make 300 or close to it on stock ls's

 

With upgraded Injectors and/or upgraded fuel pressure. Upgraded pressure tends to lead to injector failure in a hurry. Read the original question. I said the same. The stock LS bottom end is good to 300 hp. And, it can be done on stock injectors, provided you crank enough pressure. It was quickly pointed out in the following post, that the injectors won't last long that way.

Oh, and a FPR is basically as expensive as a set of injectors, and you really need both to operate the engine properly....But...

 

Get some fucking 440cc injectors and go get tuned.

Is it that hard?

 

Only when the criteria of the original post was stock LS with STOCK injectors....

Is it so hard to read?

 

No, but is it hard to provide him with a simple answer?

He needs to get some injectors. If he turbos his car without getting injectors, he is a idiot.
