I am in the process of building a bigger motor for our track only drift car. I would like to make between 350-400whp preferably at around 80% duty cycle. We are running a gt3071r with a .86 gt2871r exhaust housing/wheel. 850cc top feed injectors. Je 86.5mm pistons. BC springs and retainers. Power FC D-jetro. We are back an forth between cam set ups. I currently have BC 272's. We are considering 264's or a stepped setup. I need advice/numbers from guys with a similar setup. My budget is not huge so I am very concerned with reliability. That is why I would like to see 80% duty cycle. We will be running pump gas. Anything you can offer is helpful. Thanks,
JKP
