HKS Cams

I may have the opportunity to own some HKS Cams But is it worth it on a standard engine?

My car car is running 300bhp on nistune , full goose exhaust, blits filter, AP 4 paddle clutch, FMIC, AVCR. Engine internals are stock as far as im aware!

The HKS Cams that I may buy are on standard pullys aswell, so would I gain anything by fitting them & would it be worth it?  

yes you will gain a lot more midrange gaz but trouble is seeing as you have the rb box I don't think youll notice any real difference due to the high gear ratios

so in short I wouldn't bother fitting them

Ahh yeh I see your point Bob, Ill just leave them then as mid range is very good anyway & like you say RB box prob puts a stop to a lot of tuning I guess
