I don't see the problem as long as u have fully
maintanced it...sparkplugs, plug wires
filters, changed cm30 innercooler pump, oil changes and
u might want to get a heat exchanger too

I'm running the 185MM crank on a high mileage. Installed around 85k, and I'm at 105k now. Spark plugs, wires, everything maintained...

Try to find a used C3P SC pulley. Its an easier install and with a tune, will do about the same as the 185 Crank Pulley and tune.

I thought Code 3 SC pulley and tune equals 178mm Crank pulley and tune? While 181 and 185 are boosting higher than that?

Correct. C3P or 178 = around 17.5PSI, 185MM = 22 PSI of boost. From what I've researched C3P is actually 16.5-17 whereas 178 is 17.5 or slightly higher. This is how I look at it. C3P is potentially the more reliable setup due to being a smaller SC pulley rather than 178MM being a larger crank pulley. With the larger crank you are also overdriving all your accessories/pulleys. This will cause greater wear on A/C compressor, power steering, alternator, etc... With the smaller SC pulley you're only overdriving the supercharger. However, there is a limit to making the SC pulley smaller. C3P is right at this limit. With the 185MM you're capable of boosting higher.
