Personally I'd sell the car and get something designed for more power..evo fq360 etc! Buch runs over 400bhp in his LCR, may be worth dropping him a PM when you have enough posts to do so. Can't remember his username but a quick search for "buch and backdraft" should find him!
Another option you could consider, with your stage 2 get methanol injection - this requires a fair amount of time and knowledge to set up; but the result of the increased octane from the methanol will allow you to retard the timing by around 10 degrees with approx. 3bhp per degree on a good setup..yielding 300bhp. The water injected with the methanol will also cool the burn, giving cooler exhaust and cylinder temperatures, and cleaner combustion chambers. Have a read of DPJ's readers ride for more information on this.
