Can someone please tell me if a stage 3 pulley will work with my stage 2 kit? Does this pose any kind of risk to my engine? What COULD go wrong? Also, what would the change in boost and hp be ( I believe the st. 2 is 245hp with 15.5psi)
I did a search for this but couldn't find what I was looking for.

Thanks!

 

i have the stage 3 pulley on, no problems, it's only 3 inches.

 

Why go stage 3 when you can go with a 2.9 or 2.85?

Works perfectly, not much of a difference

Stg 2 pulley = 3.06"
Stg 3 pulley = 2.99"

 

Go with Nates 2.9.

 

I've got the Stage 3 pulley in the mail. Can't wait to put it on.

Edit: what would the psi be on a stage 3 pulley? Im at just over sea level. like is it 16?

 

i have nates 2.9 pulley with stg 2 and it works very well
had it for about 4 months now trouble free!
very good quality work as well got the puley for $65 shipped

 

I have nates 2.9 and its the way to go on the Stg 2. My 2.9 is on a custom tune and love it!!!

 

nates 2.9 is the way to go adds alot from the stage 2 pulley wont have any problems will bump you from 15 to 16.5 and will put you in the correct tune because the stage 2 is rich

 

mine still runs rich
but as soon as the balt come out from hibernation im tuning her!

 

Just so other people know, it was 65.00 because it was shipped to Canada.

 

o ya i definatley shouldda added that! even still best $65 ive ever spent!....car wise that is!

 

I'm getting the Stage 2 kit & thinking about getting Nate's 2.9" pulley....


Do you "have to" run colder plugs with the Stage tune & a 2.9" pulley???

 

yes i would put colder plugs in i have step 2 colder plugs and they are good i feel anything under 3" pulley size u should get different plugs i got mine from zzp

 

i got 2.9 and im boostin 23psi...

danm forgot i have a clogged cat and my motor will blow if i dont fix it

 

Is there a How-To for putting on nates 2.9 pulley cause I couldnt find one and I would like to see or at least have it explained how to do it?

 

It's actually quite easy...

1. Loosen bolts holding stage 2 pulley on
2. Loosen belt using 15mm open end wrench on tensioner
3. Remove belt from supercharger pulley
4. Remove bolts and stage 2 pulley
5. Put new pulley on stage 2 hub and start/snug bolts
6. Put belt back on supercharger pulley
7. Tighten bolts
8. Enjoy added boost!

Hope this helps!

Step 3.5 Use Craftsman strapwrench on pulley to break bolts free. ( they used red locktite on mine).

 

I sort of get what you're trying to say.......but how is a strap wrench gonna break the bolts free though???

 

It holds the pulley so it doesnt slip . Sometimes when they have locktite on them , the bolts will be so hard to get off that the pulley will spin even when the serpentine belt has full tension on it . Thats where the strap wrench will be a life saver.

 

OHHHHH now I get it & it makes sense.....to hold the pulley when you're undoing the bolts!!!!

duh
