What I did find is the pulley needs to be 76mm in diameter and I think the width is around 32mm. This weekend I will take some measurements of mine and then get the PN from the Gates catalog. Hopefully I can see the PN and remove all doubt.........

As an FYI: the SC belt is a Gates K08022 or Magnuson M-79-08-02-020.

Vortech 2.95 SC pulley is PN 2A038-295
Idler pulley needed is (maybe) Gates 36225. I need to verify this!

little bit off-topic here but still related to these upgrades,

will be running similar to what topgunz is in regards to engine mods, what clutch is everyone using for around 500-550rwhp? I've been to a couple places here in Aus and they are telling me I need to go a button clutch anything else won't handle it which sounds a bit weird. our 370z's aren't torque monsters, any recommendations?

What's all this talk about various pulley upgrades? I thought you only ever replace the SC Input Pulley and the rest stay as they are...

ChaseZ, You are correct. The Stillen 9lb pulley replace the silver 8psi pulley (jackshaft) on the serpentine belt side. See attachment.

Weird....my 9lb pulley is Silver....the 8lb one I got from Stillen was blue.

As many of you know, there is demand for a good solution to the water to air design of the Stillen kit. I have made my own and it is working perfect and has put down 527whp on 12psi with E85.

I do not think I need to go into the benefits of going Air to Air since anyone reading this will know just how terrible the water system works. Anything over 9psi is playing with fire. The Air to Air is coming in just above ambient on my setup and I will be utilizing an even bigger intercooler on the presented kit.

I am working on making this kit available for purchase. I am going to send all files to a very reputable party to have them build the components. I am going to test fit the first kit on my car then have it dyno tested. I will post results as soon as possible.


Kit will include:
-New Air filter - Eliminating stillen Y intake and small dual filter design
-Piping from Supercharger to intercooler
-Bypass Valve Mount adapter
-Treadstone Intercooler rated for 720HP
-Intercooler mounting brackets
-All cold side piping and intakes - 2.75" Custom Y pipe with MAF housings - Blow through design will allow computer to see temps unlike current design
-Manifold Block off plate (with gasket maker)
-All silicone couplers and T-bolts
-Vacuum hose
-Installation instructions

Possible Stage 2 kit:
Upgrade to V1 or V2 Ti/Si head unit - Capable of more power than the V3. Will come with all necessary parts to upgrade to this unit.

This kits cost is $1475 shipped. FREE SHIPPING AND ZERO PAYPAL FEES

The hardest part about installing this kit will be taking the aftercooler out of the manifold as this requires the removal and re-installation of the manifold. Other than that it is about as difficult as installing a Stillen Gen3 cold air intake.

EDIT - Can pull out aftercooler and hacksaw it off if you would prefer. No need to take manifold off and put back on.

Here are some pics of the kit installed on both a G and a Z. You can see there are different BPV options as well with this kit. I will help you with what you need.

I know 928 you can choose between clear aluminum or black. It haven't seen a srillen one that is anything other than black. JB pulleys are right from Vortech I believe and not coloured either. Not that it makes much difference at the end of the day. I'm just glad my bright green belt has turned mostly black now lol

Super weird. You should put a caliper on those.
