If you really are serious about running a sub 3.0 pulley- you really need to be saving for an IC or cam/heads package.

 

Most likely both if you really want to make power. You could get down to a 3.0" pully pretty easily with an intercooler and rockers though. If you want to go any further than that, you're going to need to run a cam and have some head work done.

il probly go ahead and do the inter cooler and rockers next summer, and go ahead and do down pipe and cat back and 3.5 pulley for this summer. thats if this zex kit i just bought doesnt destroy my engine lol. keep your fingers crossed for me gentlemen. im only gonna run the 50 shot nozzle on it though. may test it tommarrow?

 

Who said you can't HV3 a supercharged setup

L36 FTW :P

 

If your goal is to run a small pulley, then ditch the downpipe idea and just go with headers.
There is a thread very recently where so much header information was posted that my fingers cramped up from typing it out. Look up my recent posts and you'll find it.
If you're just looking for performance, then skip the catback idea. You'd just be wasting your money as the stock catback will handle pretty much anything that a supercharged setup can throw at it. If your goal is a louder car, then by all means go with the catback.

Well technically that is for a turbo setup, but I get your point.
So, I offer this correction........

For turbo setups, L36 LIM/UIM FTW.

Wait, actually......For turbo setups, L26 UIM/LIM FTW

How is that for a turbo set-up?

It says it's an L67/L32 -> L36/L26 conversion...

This is a conversion kit that will elliminate your supercharged lower intake and blower and replace it with a modified L36 lower intake, HV3 insert, and new revised L36 upper intake manifold.

 

Blower = Supercharger (slang term).
Now read what you wrote again......

If you read the full paragraph from the ZZP page, the other half of that paragraph that you pasted is this....
This means you have OEM reliability, noticeably quicker spool, and 15whp over the typical m90 blockoff plate and m90 empty case.

Superchargers don't spool. Also, why would use use an empty M90 case with an M90 blockoff plate unless you were running a turbo?

On the supercharged cars, the supercharger IS the upper intake manifold.

When people go turbo with the L67/L32, it is common to just gut the supercharger and use a block-off plate.
This is not nearly as efficient as running an plenum and intake with long intake runners like the L36/L26 uses if you are disabling the supercharger and running a turbo.
It is also common to use the intake manifolds from the f-body, as they are cast aluminum as well. The only problem with the f-body manifolds is that they have the throttlebody on the passenger side (which may not be a problem if you are using an intercooled turbo setup).

See what I'm saying?

*Note: Technically this could be used with a supercharger, but only if you were using a CSC.
