looking at all my options trying to find cheapest one. wanting over 300rwkw but NO risk of bottom end. currently looking at ba or ba mk2. ba's are 15-17k ba mk2 are currently 22-24k so either fully built engine,buy a typhoon, buy a BF after 06/06, just add typhoon bottom end,rebuilt stock motor motor,have 300rwkw tune but daily tune of 250rwkw. whats my options? and approx how much do they cost?
