I have my eye on the boosted performance single turbo twin scroll kit. Super easy install that I could most likely do in my garage will save a ton of $$ on labor. 500whp with 4.08 gears doesn't sound like a great idea... Might be willing to do a complete differential swap with someone local if I go this route. The 4.08 gears make the Z accelerate 10% faster than stock for anyone who doesn't know their affect. Cost vs. gain.. huge.
