Here are two latest additions to my turbo collection. There are two K29/K27 hybrids. They have a K29 coldside, K28 backplate and K27 center and hotside. The Hotside housing is #9 A/R. These were used by Audi in 1985 in their race program. The center turbo is an RS2 Comp. The Top left is a 3ldz from a 1985 Porsche 1911. The Top right is a Garret T04E/50 trim. The wastegate in the lower left is from a Porsche 930 and will be used on the Lehmann Manifold. The Wastegate in the lower right is a Porsche 944 wastegate and its attached to an Audi Anti-lag system manifold which I will be putting back onto the Lehmann manifold.
Here is a mock up of how the system will look with the dual wastegates and the piggyback manifold.
