What size Injectors to use? I have a 2000 TA, and am doing some upgrades very soon.
So far I've got
TEA S2 5.3L heads
FLP Long Tubes
ARE LS6 oil pump
RollerMaster double timing chain
Purchasing in the next few weeks:
TR224
Chromoly Push Rods
New GM Lifters
LS6 Intake Manifold
Will I be safe with the stock injectors? (also what size do the 2000s come with? ) or should I go with a bigger injector? If bigger what size should I go to?
If I should go bigger than one thing to keep in mind is I am plannning on hooking up my nitrous kit again once I upgrade the fuel system (100 shot dry) but that wouldn't be till late in the year, so if I'm ok with stock I'll save the money until then, but if my NA setup would benefit from bigger injectors, then I'd want to anticipate nitrous use as well.
Thanks

Re: What size Injectors to use? I don't see why you will need them. But in any case, you can get a wideband O2 dyno runs after your install and you can log your injector duty cycle at that time. If your injectors are close to maxing out in the upper RPM's (normal 80% duty cycle), then get new injectors. I believe stock are 28.?lb. You can also search the internet for a injector calculator to figure out what you should upgrade to.

Re: What size Injectors to use? Mike,
I'd say go ahead and get like some 30lb. SVO injectors to run with your N20 kit. You'll most likely be fine running NA without them, but you may want to upgrade once you start spraying again.
I know that's what I have planned once I start running the spray. Better to be safe than sorry... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
BTW, If you wouldn't mind, I'd like to check out your car some time when it gets a little warmer. I think I'm pretty close to you - I work in Hoffman Estates. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
