mate while on your ps and using 202s if they die throw another one in and run it on unleaded they're worth nothing i flog second hand 202's to the hq racers $50 a pop, when i get a car to wreck/sell /fix up or drive around, i run them on unleaded, my tonner had a 202 that i run on unleaded for a year with no hassles until i put the v8 in same with the 161 in my panelvan (i didnt keep that in long) due to lack of power, if you want to use a blue one do it paint it red i doubt a cop will even look twice at a 6cyl unless its throwing out a heap of noise or your doing something wrong, at the end of the day though its a risk you will be taking i took the risk and got caught mine was a bit more obvious and in retrospect was bound to happen, i hate the restrictions placed on p-platers, it doesn't affect me anymore having been off them for a few years but its a bit over the top, i mean i had 6 hours driving before i got my licence, kids nowadays are having to do 120 hours massive tests etc, i hopped in the car drove around the corner parallel parked drove back and was done in less than 10min had a licence
