Im not sure if your engine is the 9.5:1 or 10:1 compression ratio the latter puts out 143hp. You have the option of a stroker kit which takes it up to 170 hp. Adding nos would add some instant fun.

If you are thinking of cams I would go for a mild street tune in that engine. An aftermarket supercharger or turbo would add masses of power but will cost a fortune. Have you looked at modding the suspension - lower 20mm all round with stiffer springs?

If I were you I'd get the head removed and Gas flowed fitting bigger valves and get it skimmed increasing the compression ratio slightly.

How's it going sean_tze? Have you found a suitable mod for your engine - do you know what compression ratio the current engine is or the full spec of it?
