Engine Project
To gain more power over the stock setup I have several options open to me. I can increase the displacement of the engine, fit an alternate power plant, use forced induction and/or add nitrous.
1. Increasing displacement.
This is usually the first stop for anyone wanting more power whatever the type of engine. On an Aircooled engine this involves fitting either larger barrels and pistons (and possibly a crank with a longer throw) or swapping in another engine with a larger stock displacement. As mine is 1600cc swapping in a larger engine with the T1/T3 style engine case was not an option as 1600cc was the largest size from the factory. A common route for upgrading T1/T3 style engines is go up to 1776cc's (or more). This requires machining and fitting larger barrels and pistons. However the T4 engines came in a minimum size of 1700cc and also had 1800cc and 2000cc versions. These engines came in a variety of Volkswagens over the years, initially in the 411's and 412's, then the late Type2 buses and then the aircooled version of the Vanagons (although some of these had the T1 1600).
2. Alternate power plant.
T4, Wasserboxer, Mazda Rotary, Subaru, Rover V8, 911, Type5
I've included the T4 in the above list as it's still a conversion when fitted into a Type3, details of which can be found on the Tunacan site. Engine adapters for the other conversions can be supplied by K.E.P.
3. Forced induction (Turbocharging and Supercharging)
