I don't ususally argue with David, but this time I must correct some of what he had to say about turbo's. First, the Island kit is twin turbo kit. Island has never offered a single turbo kit. Yes, there is some turbo lag, but it is not significant. Returning from turbo to standard is extremely easy and, unless you have a concours car, no one would ever know. I have run over 7+ pounds of boost on two different cars. Between the two cars I accumulated almost 100,000 miles with turbos. NO cam changes, NO piston changes, NO rings changes, etc. Neither engine ever had "internal engine problems". There were no transmission problems, either. Yes, timing is changed, but that is by "recurving" the distributor. On my first car, an '81 AUTOMATIC, the turbos were never rebuilt (47,0000 miles). On my current car, an '83 5 speed, the turbos were rebuilt after 48,000 miles. Total rebuild cost(by a DeLorean vendor), parts and labor, was quite resonable (cheap, in fact, when you consider the amount of fun provided by those turbos). I do use premium fuel. I seldom have any pre-ignition. Bottom line: Turbocharging, like any other means of increasing horsepower, has advantages and disadvantages. However, in my opinion, it is a viable, reliable and satisfactory way of getting to 185-200 hp without basic changes to the PRV engine and without affecting reliability.
