Teins own j00. I was in an IS300 with Type FLEX and theire amazing. Even the basic dampers are awesome.

Go for a Turbo. Superchargers arent as efficent, and arent as easy to get power out of.

A B18B Turbo is like a KA24DE with turbo.

Its not popular or "JDM" but it can 0wn anything in that class.

Everyone goes on about SR and RB swaps into 240SX's, but why spend 6 or 7gs to be JDM when for 1000-1500 bucks you can lay down 240whp, the same as a freakin RB25DET!
