Eurospec 5 Cyl High Performance Crankshafts Eurospec’s new line of 5 Cyl 4340 billet and forged crankshafts are available for popular Audi and Volkswagen models. These precision made cranks are a reasonably priced alternative to the custom cranks on the market and far superior to the cast stock based units available. Initial strokes available in 92.8mm and 100.0mm, they offer a wide range of options for the professional engine builder.
This new stroker kit is based on the FIA kit car specification. With a 90mm stroke by 84 mm bore and using a 150 mm connecting rod, this configuration delivers the best balance of bore and stroke on an 88 mm bore center, while still maintaining a connecting rod ratio of 1.67:1.
After many hours in port development and time on the flow bench we have come up with what we feel are the best ports for this engine available today. We then digitized the best set of ports and replicated them in all positions. See flow charts below. The heads are available in three configurations.
Available in two configurations: 2.8 liter to 3.6 liter and 3.2 liter to 3.6 liter. Each conversion consists of a 3.6 liter short block mated to either a 2.8 or 3.2 cylinder head and a preflashed ECU for a truly plug and play installation. These long blocks will bolt to all of the standard intake and exhaust systems for the particular application.
