Erik, In 1976 the PRV-6 was available as a carburetor-fed fuel system, designated as the B-27A at 125hp. This model was primarily used in the Volvo 265 in the UK, Europe, and Canada until 1978 when fuel injection started to take over. In 1979 the B-28A was introduced with a slightly higher output at 129hp. Although the B-28A carburetor versions were built and marketed for Canada and Europe there was some limited use in North America. The Bosch CIS fuel injection system was introduced to the US market in 1979 and designated as the B-27F at 125hp. In 1980 the Volvo B-28F made its debut at 130hp. In late 1980 several improvements were made and this is the model used in all DeLorean's. As you can see the fuel injected models provide more output; but more importantly, they are more efficient in the category of fuel consumption and lower emissions. For the record; the last PRV-6 was introduced in late 1987 as the B-280F, several additional improvements and a new fuel management system boosted the horsepower to 245hp. This engine was last used in the Volvo 760 GLE in 1990. As many of you already know my DeLorean PRV has over 260K miles and my Volvo 760 PRV just hit 162K miles.

Why would someone go to all that work to convert? I understand Steve's reason for doing it, but why would someone do it for the long run?
