@N20
thanks boss for the suggestion, i am looking into it but according to my calculations, the car is running perfectly and i believe stage 2 cams (crower), cam gears and valve retainer set (stage2) along with kpro would definitely upset alot of cars,
i have been offered a used kpro from Singapore for 60k, but on a stock car Kpro would be insufficient, i know i can remove the top speed limiter and lower the vtec point, but the thing is if i lower the vtec point i will suffer from excessive spinning and lastly the fuel economy i am enjoying right now will be lost (10/11 km per lltre). and yes the stock k24 pistons are low compression compared to stock k20a pistons, so i recommend 87 mm wisco pistons with either 11.1 compression or 12.5. call me if you wanna discuss about this.0322-5000016
@salik
yes we have increased the bore size, k24 stock pistons are 87 mm and they are D shaped (they dont have a crown like the one's euro R have) it is upto you if you want 13.1 or 12.5 compression, i can order any type..
i will upload the dyno video right after this reply of the k24/k20, ahad has driven it he knows how the vtec sounds and kicks in, and if i am not mistaken k24 stock pistons have a 9.5 compression ratio which is too low for the type R head.
