I am thinking of purchasing Nitrous Oxide kit for my 305 TPI camaro. The car only has 65,000 miles but i dont want to hurt the motor. Jegs has the kit from NOS that ranges from 100 to 150 HP Will it hurt my engine if i go with the 100 hp shot???

100 hp shot is just fine for a 305 tpi.my old setup was a 305tpi/5 speed with a 100 shot nitrous.the best et i got with my old setup was 13.75@100 on street tires.

if you're not burning oil, got good oil pressure, good tune, and no leaks, i'd say go for it
