This gallery is about another 1990 765 Turbowagon that I built up a tight squish B230FT motor for.

Each of the Turbowagons that I have done motors for has her own story.

Misty Blue came to me from a friend in New England [Thank You Mr. Eben!]. Although very well taken care of, the miles had begun to take their toll. At 204,000 miles, the motor overheated a couple of times, either resulting in or resulting from a blown head gasket.

What Misty Blue needed was a motor. I found a low mileage replacement because I wanted to do some different things in a tight squish build, to see the results, and to further my research on tight squish and fastburn.

This gallery is about that different motor build; and shows the things that were different from the prior builds.

This build did not involve new ET shallow dish pistons. I reused the stock FT deep dish pistons. I honed the cylinders by hand, and refitted the pistons, after they were knurled.

The squish was set at 30 thou. This resulted in a static compression ratio of just about 9.4:1....more than half a point higher than the stock SCR of 8.7:1 I wanted to see how the deep dish FT pistons would affect the squish effectiveness of my build; and how that might affect the octane requirements.

With an Acam installed and advanced 6 degrees, the 90+ manifold ported as on the other builds, the exhaust system opened up to 2.5in after the downpipe, and a watercooled Garrett T3 from a 240T located in the power seat, we would find out a few things.



***** As time permits, I will complete the text for the pics in the gallery, and possibly add a few more.
