I have a gs-r, with simple E/H/I. I plan on going turbo, but that won't be until next year. What else can I do to my car that will make it faster that later on I will be able to tune it correctly with my turbo. E.G. cams, etc. Basically, I dont want to put any mods on my car and find out later that those mods suck because it wont work well with the turbo.

 

Reduce the weight, remove power steering belt, remove A/C belt, advance timing, octane booster, be sure your intake inlet is sucking cool fresh air(not underhood air), add water wetter to antifreeze.

That's all I can think of...
