Should i replace my fuel injectors for a 2.8 pulley? And how hard is it to put the pulley's on yourself?

 

yep 60's.

you need a pulley puller.

you would need a tune as well.

I recommend getting the pulley and pulley puller from here:

http://www.smoothflowpulleys.com

or you can find everything you will need here:

thanks man quick reply i appreciate it.

 

No problem.

 

hey should i get the stage 2 pulley from the second link you gave me?

 

Stage 2 is larger than 2.8

 

Yea see i am tyring to do 2.8 pulley wondering if that was stage 2.

 

You need the hub too, try this link

http://www.ottperformance.com/Cobalt...duct_info.html

 

you "CAN" run a 2.8 on 42s, with METH, and a damn good tune! But.... that sacrifices every day drivability!

 

And one more thing am i gonna need a new belt since its a smaller pulley?

 

Yea I would get a stage 2 belt. You can also get a larger tensioner pulley instead if you want to do it the cheaper way.

 

nah ill get the m62 but get the stage 2 belt with it?

 

yea. who is going to tune it?

 

not sure yet but i was looking at the ott stage 1 kit would that be better and would i still need a tune for that?

 

I have a polished 2.85inch pulley for the stage 2 hub (4 bolts) for sale if you want/need it. Its from Nate at smoothflowpulleys.com only a few months old. great shape, looks new.

 

They provide a tune with it and everyone seems to have good luck with it. You may want to consider some other mods before you do a stage kit such as exhaust and a larger heat exchanger.

 

Nah, the stage1 from OTT includes a tune

 

Hey i got a ? for you..If you have the stage 2 belt already, and wanna go smaller pulley like a 2.7, would the larger tensioner pulley work or does it have to be the adjustable tensior from zzp?

 

well there is currentyl nothing done to it but i have have ordered is a megan racing cat back exhaust drift style injen CAI and i was gonna do the pulleys.

well there is currently nothing done to it but i have have ordered is a megan racing cat back exhaust drift style injen CAI and i was gonna do the pulleys.

 

I think the stage 2 belt should work. Im not positive on a 2.7 though. Im not going below a 2.8.

The megan exhaust is pretty loud lol.

 

i know i am gonna like it. and one more question for ya cause you seem to know alot about this stuff with the stage 1 KIT when i go to order it it says the:
PCM Core Charge: and it says email me a tune file or ill send my pcm in first
AND
Remove Torque Management: yes or no?

 

I would pay the extra charge and send in your PCM after the install, then they will refund you the money once they get it.

Most people remove the torque management and do a 7,000 RPM redline.

You have to get a case relearn done and a security relearn done after the install as well.

 

remove torque management... if you have an 06 have the tranny torque management removed as well!

 

alright thanks guys alot of help here i appreciate it.

 

If you PM fast98 or lsjwannabe they can help you more than i can lol
