I have the K&N drop ins, Tanabe Medallion, with custom midpipe, Beluga Y pipe, with Berk HFC, wondering what mods I should do next for performance or just call it a day. I realize going further will cost more money per hp. I’ve owned turbo cars before and not interested in going turbo (300ZXTT, old Supra, Turbo Honda). I’ve done research and I see ported intake plenum, Jwt cams, etc. I’m not interested in a CAÍ or long tube headers. I figure once I do the next round of mods I might get a tune. Any insights would be appreciated.

 

Headers then a tune then call it a day. Unless you're interested in e-85
