I'm interested in doing those 3 things to my 2003 S55 to make it once again the King of the Hill.I have no problem beating most street cars in the quarter,but the new 5.0 Mustangs are giving me a slight problem.I live in MS..Where can I order the pulley kit?Is this the best place to start,or is there some type of performance chip available?

Im coming from the diesel truck world so Im used to endless upgrades. Im looking for a daily driver/ weekend warrior.
Could you lay out a list like the one ill make below?
FOR EXAMPLE
500rwhp- pulley upgrade and exhaust
550rwhp- above + ecu tune
I just wanna see what kind of power levels I could do.
Thank you
Blake

Can someone tell me how hard or easy it is to install a Johnson CM30 IC pump? Do you have to prime the pump, or bleed the system out of the coolant? Or is it a simple plug and play procedure; Instructions on install?
Lastly wheres the cheapest price around to get a hold of one of these?
Thanks in advance.

I think when switching from the original Bosch to the Johnson pump the hardest part by far is the wiring, the rest is pretty much a straight forward swap over.
Some people claim to have some small issues with the clamps and others dont, so thats another hit and miss area.

I'm getting into this now. Likely settled on a 175mm ASP crank pulley (a little over 13psi boost), secondary cat and resonator delete, and tune. May upgrade to a Johnson pump, maybe a new OEM (I'm told the factory one has been upgraded, I'm chasing that down with MB now). The theory as been to go for better throttle response and exit of exhaust gases (exhaust and tune), with more boost but not enough to cause heat or stress (175mm v. 180mm pulley). That's enough for me. I'll report back with observations.

I would stay with the stock crank pulley, and go with a smaller S/C pulley. Lighter, less rotational mass, gets ride of the clutch system, no more chirps, and injectors, and a tune.
