Stage kit questions??
Hey guys will someone help me with this? Question is can you run a 2.8 pulley without cams?? Turbo Tim at zzp says I'll need cams to run below a 2.8 pulley and he says the 2.8 is one size too small and I will need cams with It.. It doesn't make sense to me cause all the stuff I've read about these kits says that if you run a 2.7 or lower you will need cams! Someone help
Im running a 2.8 without any issues at all. You can run the block stock on any pulley but if your are building the engine for power, adding cams is always a good idea. Figuring out if you are going to keep the car supercharged or go turbo swap will also help your decision on how you mod the car.

im running a 2.7 just fine on my stock internals, no cams. to make better use of the extra boost cams will help, but its going to affect driveability.
dont worry, toss the 2.8 on there with 60lb injectors. im not sure why zzp is now insisting cars cant idle correctly on 60s, my car idles great after i took their crappy tune out that gave me idle issues, warm up issues, and set lean codes. they sent a couple flashes to me to get full throttle correct then ignored me. i tuned the car myself, as an amature with hp tuners i made the car run a heck of a lot better than they could.

Here's a question for you. Theoretically if you had complete bolt ons, injectors, etc.. could you just change a pulley and not need to change the tune? And if you do need a changed tune what do you change?
well zzp dosnt give you an option for their pcm. someone said the computer can adjsut for this, this may or not be true, but IMO, they prolly run their tune rich, so if someone does put a smaller pulley on, it will be safe also. almost same as what people do with the gm stage 2 kits.

I'm a believer in hp tuners also as far as getting more power this allows you to have a more accurate tune based off of your mods plus every car is different so they will all react differently to certain mods
when you get some mods on the car it is better to have the car tuned properly instead of a canned tune. you may or may not make more power (in my case i doubt it, im still running the same timing table and afr is about the same), however everything will be set up correctly. full throttle, as its the most important to keep the motor in one piece, isnt the biggest deal in tuning. when changing to bigger injectors, different intakes, etc its a lot more work to get the idle, cruise, medium throttle, and coast down set correctly to make the car drive like stock.
i spent about 6 hours this weekend driving around tuning my car. 5 hours was spent working the error out of the ve table, cleaning up the maf calibrations and some other tweaks for light and medium throttle. id say less than an hour was spent correcting the maf calibration while in power enrichment, i think i flashed it 3 times and i was happy.
in theory, depending on your tune you should be able to drop down a pulley without issue. the theory is dropping a pulley size just gives less air flow, and your maf will be reading less air so the computer will command less fuel. in a perfect world that would work, however its best to always log and tweak it as needed.

by stock i mean driveability wise. i want the car to drive smooth, idle nice, start and warm up smoothly, have good throttle response, and get decent fuel economy. thats how a stock car drives. i dont want the car to bog, buck, idle rough, and set codes. on top of this i want the car to go like hell when i step on it. with the zzp tune my car went like hell but didnt do everything else very well.
modern fuel injection is a wonderful thing, and tuned correctly, even a highly modified car should be able to drive smoothly without feeling like a highly modified car, till you step on it of coarse.
