    Default Few more Bhp?

    What else can I do to my Z20NET to get a little more Bhp from it? I have Stage 1 BSR fitted, cat back exhaust. I have done the airbox mod. I would like about another 10Bhp

    Really? Does taking the seats out actually increase BHP?

    How about freeing the breathing up a bit more? De-cat (and do they have a pre-cat like the Z20LET?)

    I took the pre-cat off my Coupe and it made a massive difference

    viper stripes! The amount they give you varies. If it is at a Vec C forum meet it reduces it by 10bhp, but parked up at your local Macdonalds drive through they are good for 25! Unfortunately mate I haven't got anything useful to say above and beyond what's already been said!

    Have you tried putting performance spark plugs in? I had a Pug 306 Rallye a few years ago and replacing the plugs for performance ones made about 10 BHP gain.
