campro 1.6 normally my customer use H-tech 5w30 and turbolight 10w40.but u can feel the H-tech 5w30 more power it because the spec is more lighter the 10w40. the price for H-tech RM165 and turbolight RM145.
Have recently seen quite a number of 350Z with super charger for sale. Have no experience in VQ before and was wondering is it a good idea to do so provided that supercharging kit from HKS or others.
