Finally Going to Mod the 03

[Koild Up]

I have a friend who is selling his Whipple 2.3l on the cheep and im going to get it. He made around 550hp at 16lbs i believe. Has low miles on it. I have one problem, my motor is around the 75k mile mark. Ive done some research and here is what im looking to do.

Got the "tick" to fix
Irs bushing kit (MaximumMotorsports?)
Irs Brace (billetflow?)
Upgrade intercooler(?)
Upgrade clutch (?)
Bassani offroad H
Borla Stingers
Lowering kit (eibach?)
Some kind of cold air kit (?)
SCT tune/chip
Injectors/fuel pump?

This is going to be a steet vehicle only. Is there any mods im missing. I want to get around the same Mid 500hp. Since the motor will have to be dropped to get the heads fixed, should i consider new bearings and such? Im looking for ideas on which companies to purchase and which to avoid and where are quality places to purchase parts.. I have seen your cars last year at Summit and they looked awesome. I have already consulted on some prices from Terry at Street Lethal i just need to get the parts together. Thanks for any hellp guys.
