I just bought my injectors, and Im about to buy a modular pulley syetm, ( Im peiceing together my own "shane Stage kit" lol) everyone with small pulleys how many of you replaced your belt, I want to go striaght too a 2.6 but do I need to buy the shotened belt? is slip that bad? I called a dealership there gonig to give me a GM stage 2 tune for a hours worth of labor $, is that ok with a 60# and a 2.6? what eles will I need? do I need new plugs if I do what gap should they be at? do any of you reccomend a different size pulley? buying the smaller belt isent a problem. so give me advise!

thanks a head of time. =)

buy the belt, i dont need 1 with my 2.9 but any smaller and yes

 

You'll need the smaller belt, plugs, possibly a tensioner as well (some do, some don't), and you'll need a tune.

 

you will need a gm stage 2 belt you will not need a tensioner unless you want to go smaller. I have no belt slip. You will want to tune with HPTunners make sure you have supporting mods for the 2.6. Exhaust, and cooling, wideband

 

yeah gm stg tune is only good for 42lb injectors.. won;t work good at all and flood with that setup. also I would recommend the ZZP adj tensioner and gm stg II belt. or else you will get 0 boost and a **** load of belt squealing

 

Stage 2 tune will not work with 60# injectors.

 

You cant run 60 and stage 2 tune.... so this is correct

 

why cant you run 60#s on the GM stage 2 tune? will it hurt anything or just cuase me to runn rich or lean or what?

 

It will definalty hurt the car, car will most likely go "boom". You need to be HPTuned to run the 60's.

 

i differ on the tensioner you can if you want, I have had no belt squeal and hit 20lbs all day long with no slip. and I run a 2.6 gm stage 2 belt. Yes I would recommend it but you can run without any problems

 

The GM tune is meant for 42#. It will run like ****...if it runs at all.

 

is there anyone in MD that will HPtune my car for 60#s and a 2.6? Ill pay too, if not in MD and in a surrounding state we cna figure something out,

anyone?

thank you, soo get the belt is what Im looking at,

 

Without my tensioner on with the 2.6, I had belt slip. Your not the only that I have heard of who hasn't had any issues without the tensioner though. It must be one of those "hit or miss" things.

 

what pulley did you go with zzp or intense

 

not sure yet, whitch would be reccomended,

and DOC said hell tune my car on the 7ths of april, is it ok to put the stuff on my car and then drive up to the car meet for him to tune it, or will in at like hour drive my car die?

 

NO NO NO !!!!!! PUT IT ON WHILE HE IS THERE OR U GONNA **** UP THE CAR

 

you can probably do the pulley before you go just do not go really hard on boost. The injectors i would do upon arrival.

 

I'd recommend the ZZP pulley, thats the one I have and it was a perfect fit, no snout machining needed. And I wouldn't put the pulley or injectors on your car until you get to where you are meeting Doc to tune it.

 

Doc, some redline newb and I just did a 2.6 ZZP kit install. Yes you have to machine the snout, yes u will get belt slip without an oversized tension or adjustable one with the smaller belt. Takes a while to machine the snout as well so keep that in mind, its a pain in the ass.

Im curious to how the dealership was going to give u the stage 2 tune when you need the code from the stage 2 kit.

 

On the adjustable tensionser thing... the belt stretches after a while.. I got away with it for like 2.5 months and then I started loosing boost... put on the adj tensioner and all was good again.
and on the ZZP pulley.
sometimes it fits with no machining (2.6) but if the snout is out of round (like mine) you need to sand it down in areas... I've done 6 2.6 install and only 1 needed to be machined (mine) and the others needed minor sanding.

 

it sounds like if you didnt come on this forum you would have a blown motor by now

 

lol no, I would have done my reasearch eles were

buut thanks everyone for the advise,

so I can putt on the 2.6 pulley and take it easy, just not hit boost and it will be ok?

 

still not a good idea at all man... please do not do this
