Just wondering what the best injector to run would be on an
L36. Im looking at a ZZP canned tune, and a full exhaust from ZZP. odds are im going to end up doing both. But i wasnt sure what the best injector would be for better performance

Thanks

 

Stock injectors.

The reason why is because you only need to upgrade the injectors if you are getting close to maxing out your current injectors. This means that if the injectors that you are running cannot deliver enough fuel compared with the amount of air flowing into your engine (afr) then you need to upgrade. If you are upgrading just to upgrade, you will gain nothing hp wise (waste of money).

Here's another way to look at it. A stock L36 powered car makes roughly 150-160whp (~200 at the crank). When I was NA, I added a GT1 cam, p&p heads, thinner head gaskets (which raised compression), headers, removed cat, 2.5" exhaust, HV3, ZZP's stage 1 t/b, w/p udp, fwi, NGK plugs, 10.3mm wires, and a custom PCM tune done by ZZP on their dyno and made 222whp (the video is on my Youtube account). With all of that (and maybe a couple other things I forgot to mention) I wasn't even close to maxing out my injectors.

Usually, 3800's don't need to worry about getting bigger injectors unless they are boosted. The only way I could see an NA 3800 needing bigger injectors would be is if you converted to E85. Otherwise, spend your money on parts that will actually make you gain hp.

 

why you want to upgrade your injectors? exhaust and pcm mods are not going to make huge power by replacing injectors. your stock injectors are fine for the upgrade, unless if the injectors are going bad then i can see replacing it for another stock size injectors.

 

alright i appreciate the info. i just wasnt sure if they made any HP gains or not, but ill save that money a spend it where it matters!

 

Get headers then boost. Then take it from there.

 

i wouldnt think you need a tune yet. save that money for now.
get the exhaust, do an intake if you havent yet. then the HV2/3 from zzp, speed daddy headers, then look at a tune from Overkill or if you can find someone local with a tuner you will be much better off.
