    What Jesse said ... your question is way too open for us to answer. There are so many SC options, and many of them require fueling mods, so you have to decide on something ... either the max speed you are trying for, the max $$ you want to spend, or what parts you WON'T change (like ECU, stock intercooler, etc). For some ideas take a look at the 4-tec speeds and mods post in the sticky section.

    You may need the mechanic to wait until you do some research and decide exactly what you want to do ... there are a ton of choices. You do have metal clutch washers already, right?

    You could do a drop in wheel like the Greenwheel in the store with no other mods other than what you listed (and go maybe 73 mph), but if you add an aftermarket intercooler, then you would need to upgrade your fuel injectors to 42s. That is a great simple setup that will get you 75 - 77 mph without messing with valvesprings or ECUs.

    A Riva pro series (S3) would complement the Stage 1 kit nicely. You will want to upgrade to 42 lb injectors with this supercharger modification.

    Don't forget the greenhulk coupon code when checking out in this sites online store which will save you 10% off the Riva parts.

    Also, leave a note in the comments section when you place your order and i will substitute the 15/20R impeller for the 14/19R that comes with the stage 1 kit.

    We just exactly as you want on an RXP, but used an X charger. It did 75 mph in average conditions, probably 76+ in better conditions. The out-the-box 15/20 works perfect with this combo. We installed the RRFPR with stock injectors, but I think it would've been fine with no RRFPR and 42's.
