here i come 
Evo and WRX is piston engine lah.....RX-8 is rotary....and less bhp
coz of no turbo ...but 215 bhp is impressive for a non-turbo
(rotary)engine....and there's a another version which i forgot the
name that have 250hp....WRX and evo got their hp form the
turbo....RX-8 make up for no turbo boost by providing 10000rpm to
rev...and redline's at 9000rpm
