local price would have been $2900 cash. yes, this is a complete kit, you don't need anything except one step colder spark plugs which you can easily buy it on eBay. the other thing you need is to get the car tune right after you install the procharger. if you've bought, i could of help you or maybe install it for you too. i prefer local sales, save me the trouble of shipping. but one guy offer me $3180 shipped, so far the sale is almost consider sold.

 

it pretty safe if you install it correctly and with the proper tuning and running a conservative boost. modifing the cooling is not needed but is always better. as far as shorten the engine life, it might or might not, i really don't know the true answer to that. many guys on the this forum and the 350z have modded their car way over the 400hp and still running fine .
I use to have a HKS Stage 7 Supra turbo with over 130k miles with no problems at all. I really miss that car
