Vin #6068 had a ISLAND turbo kit on it running 6Lbs of boost, and I believeit had been running with a cracked ring for a few years. The engine is out of the car, but has not been disassembled yet to find the cause of the problem.. When I get around to it, I will report what I find so other Turbo owners can be warned.

While in Memphis, I spoke to some people who had turbo kits on their car. All denied having any oil burning problem, or other engine related problemsdue to the boost.. One guy was even running 10Lbs and claimed he had no problems.. I later saw this car with black smoke out the tailpipe AT IDLE (even my car was not that bad!).

I agree with David, that to run boost on our PRV engines more than just a bolt on kit is needed. One requirement is Fuel Enrichment, which in most cases is a pressure switch to ground the O2 sensor. IMHO, this is not enough. I'd also look in to replacing the pistons, rings, and head gasket with items from a Alpine (310/610/GT) which were designed to be used with Turbos.Of course, this becomes cost prohibitive; which is why #6068 is undergoing a engine conversion.

Many of you saw #1860 this weekend in Memphis. While it is not obvious from the outside, Legend changed just about every part INSIDE the engine and they did not do this for fun. They did it because the stock PRV just cant handle the boost. BTW, This car made the 2200 mile round trip with no problems.
