Buying a 2.87" Pulley.

On Vortech's site, it says:
"Requires retainer assembly for installation (not included with pulleys)."

Is that something I have to buy and replace, or just reuse the one on my SC now?

Also, right now I have the following:

V1 SC
Cartech Adjustable FMU
SAFC I
1 Step Colder NGK Coppers
MEVI
Stillen Aux Fuel Pump

Anything else I need before I take the plunge?

Also, is the correct Part Number the 6-rib 2.87", PN 2A036-287?

Thanks,

What ever happened to the belt chart that was up awhile ago? (Gates part numbers)

Anyone want to post a link for me?

Thanks,

post not too long ago for belt lengths

 

Gates belt Size: K060703

The only other thing you might want to consider getting is a Walbro fuel pump and injectors..

 

You might need 300ZX injectors too

 

I have to agree. From what I've researched on the subject, the 240 cc/min injectors are good for about 321 hp at the wheels (assuming bsfc = .55, duty cycle = 100% and fuel pressure = 100 psi). Jay is getting 320 hp at the wheels with a 3.25" pulley (iirc) and MEVI, and his afr shows signs of injectors being maxed out at the top end. So for safety's sake you need to think about providing more fuel with larger injectors.
