I'll need to pick up some injectors with my STS kit. I've searched around, and it seems like the crowd is split between 42lb and 44lb injectors. Being that I'll have an I/C STS system with Meth injection, which size would be best to go with? I'm not totally performance minded, and would like to increase mpg as much as possible- does this mean I should go with the smaller injector?
Finally, what brand do you recommend- Delphi, Venom, etc.?
Thanks for all of the question answering!

really there isn't much of a difference between them, if you max out a 42lb injector you would be damn close to maxing out a 44lb as well. I don't think that gas mileage would change either with the proper tuning.

 

Honestly, the difference is mostly who did the flow testing, whether they round up or down, etc. Most 44# injectors are really 43.67, most 42s are really 42.xx...

 

They are the same thing, difference manufactures rate them different. Same product.

 

and no difference in mileage.

They are the same thing as stated above. I think that you should look around and see if you could get a set used for a good price (check the classified section). Usually you can find them there for around 200.00 for the set.

 

Thanks for the quick replies! 44lb injectors it is...
That explains why there seems to be an equal share of both out there.

8ALTNG- Sent you a PM.

 

Prices on the Racetronix website:
$48 per 44lb injector
$35 per 42lb injector

Since they're practically the same in flow rate, guess I'll be going with the 42lb instead.

Anyone see a reason why this (http://www.racetronix.com/621031.html) injector wouldn't work on my 06'?

Thanks again...

 

I don't think you want those. You want the Delphi Multec II Shorties that are a direct fit for GM LS1 SUV.

Then you don't have to shim you rails or replace the pigtails.
