Type-R Valve Spring market price should be around RM350~450 depends on your luck if you can get it cheaper.
As for cams. CTR should be around RM1200~1400 and ITR should be around RM100~1200. It is also depends on luck with the price you are getting. As all item is second hand or half cut unit.. So eventually it doesn't have any FIX price.. If they wan to sell higher they will blame on the yen rate is high, stock is limited, blah blah blah...
