Hi,

steel sleeves have some disadvantages, because of the open deck engine design and the aluminium block.

If you rebuildt the engine and have the opportuninity to change internal components you can add a 2 KKK turbo chargers. Than the 3.2 should be able to reach realistic 330 HP and more. For example Gemballa put out 350 HP and 450 Nm out of the 3.2 engine with a Bi-Turbo conversion. This engine also had sport cats and reached Euro 3 emission controls.

As a non aspirated engine it might be possible by removing cats completely and use a lot of expensive components so you can raise the rev limit around 1.000 to 1.500 RPMs. Think the stock block and crankshaft can handle that, but there are a lot of components that have to be improved, lightend and optimized. Cooling has to be optimized. Also you will need an individual ecu remapping… i'm not shure if you will get real 330 HP. 300+ HP should be realsitic.

TechArt offered a 3.6 litre upgrade and reached 325 HP and 375 Nm with full emission controls able engines.
