car is stock besides a K&N CAI..gonna want a tune to turn my fans on sooner so the coolant doesn't spike up as much so might as well put some fun stuff on at the same time; piece of mind thing. anyways, how does this sound?

ZZPerformance - Cobalt/Ion Modular Pulley System #
takes care of the pulley/hub

now here is where I'm kind of confused..I'm going to get a 2.9" pulley will I need the GM stage 2 belt and be fine or do I need the Oversized Tensioner Pulley also? Don't want the belt to slip..
ZZPerformance - Oversized LSJ Tensioner Pulley #13-02-00883

60 lb injectors

and of course I'll have Nick at BYT put the parts on/tune the car for the new mods..

any and all input is appreciated

 

I have brand new 50# injectors for sale. When I bought my kit from ZZP I changed my mind and decided to go e85 and would need 80# injectors for that. Let me know if ur interested!

 

you do either one but not both for the belt/tensioner.

 

do you have a harness? assuming these won't fit in the stock one..and how much?

thanks, ill get the belt tensioner then since it's cheaper

 

The 50# injectors use the stock harness and I would do $110 shipped brand new. Thats $50 cheaper then ZZP. I would also send them with my stock harness if you wanted it, but doesn't matter to me

 

And yes you are more then fine with the GMS2 belt and a 2.9, you will have no problems

 

any idea what capacity I would be using with a 2.9 pulley and 50# injectors? I read a 2.9 and 42's was at like 98% or something like that

 

When I went to ChevyCobaltSS3 (James), we tested them and with a good tune we were at like 77% or something like that. Obviously running rich with bump that up. They work perfectly fine, people are just sceptical of having them because ZZP has always used 60#'s or 42#'s.

 

zzp says 50# is good for any m62 build beside e85

 

that's fine..i'll PM you tomorrow. I'll take these off your hands

 

ok man sounds good. if you want pics and stuff just message me a number and i can text them too you!
