Ok, I really need some help on this one!
I just installed my 2.8 ZZP pulley, after fighting with the damn bolts for a few hours. I started my car and it idled perfect, even better then I remember! I decided to go get some fuel for the morning and I soon found out that AS SOON as I go into boost, the car starts sputtering REALLY BAD!! If I hold the throttle down for a little bit, it continues to sputter and then the CEL flashes on and off for about 30secs and then turns off!? I'm not sure why the CEL is not "latching"? At least then I could get the code! Has anyone had this issue after intalling a smaller pulley?? NEED HELP!

 

are you tuned for a pulley swap? My guess is no.

 

i hope you have 60# injectors and a tune

 

i have a friend that has a 2.8 on stage 2 and runs it fine....every car is different....u dont NEED a tune to run it but it sure does help alot

 

heh...heh...

 

I have a stage 2 kit and tune...I'm getting a dyno tune next month...should I put the s2 pulley back on till then?

 

do you have 60 injectors? cause i know a 2.9 on S2 maxes out the 42# injectors

 

yea deffinatly

 

So are the 60lbers required for a 2.8"? I thought that 2.8" was the MAX for the 42.5lb?

 

u can run any pulley u want on stage 2....wether or not ur engine responds or runs good to it is a differnet thing.....60lbs are RECOMENDED for a 2.8 yes

so...if u want to run a 2.8 i recomend geting 60's and a tune which defeats the whole purpose of stage 2

 

theres people running 2.8's on 42# but with a good tune, not off the stage 2 tune.. I don't care what anyone says, it is not SAFE to assume that your car is one of those freaks that can handle 2.8 fine on stage 2 tune.

 

Crap, now I have to convince the wife that I need to buy new injectors! I just got outa the bad books for buying a $700 exhaust for my quad!

So do you think that if I bring the 2.8 with me when I get it tuned that I'll be able to use the 42.5lb injectors with the 2.8 on a good tune?

 

i absolutely agree tho i do have a friend that BEATS THE **** out of his car with 2.8 on stage 2 and it runs fine...stoich also haha

 

my car runs fine with my 2.85inch. but im still going to put 60lb injectors on it with a dyno tune in the next 2-3 weeks hopefully.

 

what 42.5lb injectors??? stage 2 is only 42

 

talk to area, mdub, wickedss2005, etc. them as well as people they have tuned have ran 2.8's off the 42#'s without a problem. If you have a reputable trustworthy person that knows what he/she is doing then yes

 

its not recomended because IDC's are maxed on the 42's it would make sence to get 60's and a good tune

 

huh....

probably not for long. As stated above you will be maxing out, more than maxing out the duty cycle on those 42s, even with a good tune. Dont cheap out, 60lb injectors are alot cheaper than a new motor....

 

^ well said

 

i would go get a set of 60s and a tune quick before u blow that car up. Your def running out of fuel and messing the car up really bad to get the flashing check engine light!!!

 

[QUOTE=bigrroberto;2206213]Ok, so the only additional parts I should need are the 60# injectors and a tune?

 

yes i believe so

 

correct......even tho if I was getting 60s id get a 2.7...thats just me tho haha

 

That sounds like a good idea actually...HAHA, anyone wanna buy a 2.8 Nah, I think I'll just get the 60's and the tune for now. I just hope I can get the injectors before I go for the tune next month...
