Now that you have oil it will be time to upgrade the turbo. I saw in another post you were trying to find a turbo system for the van. Hypermax makes an older van kit, impulse I think. For your application, now that you have oil, a QSSB would be a great option. Depending on how much fuel you decide to flow or even with a 120hp program you will go so far outside of the stock turbo's pressure map it won't make anything but heat. I have been really happy with my QSSB and have over 40,000 miles on it. The EGT drop alone was worth it.
