Pretty cool that you've owned the car since new.

I'd skip the Eaton supercharger crap and go with a turbo kit. The ZZP Z3 kit would be killer. Order it with the air to air intercooler, or go cheap and order it non-intercooled and throw a cheap meth injection kit on it.

You'll see much bigger gains and feel a much bigger difference with a turbo setup. You'll also have a lot more 'room to grow'.

I liked my blown Monte SS a lot, but looking back I wish I'd have gone turbo. I think a non-intercooled turbo setup with post-MAF meth injection would absolutely kill as far as being easy to install, cheap, and having massive gains. I've got a ragged '00 Regal GS that I might eventually do that too to make a super sleepy street sweeper.

 

I've looked at the turbo direction, but its a grand more then the supercharged way, and I don't wanna spend that much cash. when looking into adding the supercharger, why are some of the people taking off the valve covers, basically the top half of the motor? correct me if im wrong, but when doing the L36 Supercharger Kit. All you need too do is tare down too the lower intake gaskets right? unless they are doing some internals with it, and you would use the intake manifold that comes with the kit.

 

They are probably doing a top swap rather than the ZZP supercharger kit. A top swap will take everything from the head up from a L67 and you'll put that on your L36 block. A top swap would be cheaper but more labor involved.

 

Here's maybe a stupid question. After this install will these keep up too a stock 5.3 SS

 

not with the 4.2 pulley it wont.

 

why would you freeze the injectors?

 

Like not even close? How about with a 3.8 pulley

 

With the 3.8 pulley and adequate fueling, yeah, it'd be close. With the 4.2, probably not. Maybe with a very lean AFR and a ton of ignition timing.


The bosses drilled into the lower intake were too small by a little bit. I stuck the injectors in the fridge to shrink them a little, greased them way up, and installed them cold.

 

lean is fast, but dangerous.

op i wouldnt be to worried about keeping up with stock ls4 cars, theyre not an unstoppable force, or fast. not to mention that any of them that arent owned by geriatrics dont stay stock for long. your best bet would be to figure out what you want your car to run in the quarter and then come up with the combo to get it there safely and reliably.
