The Theta Engine is the part of the series of engines created through a joint effort with Mitsubishi, Hyundai, and Chrysler, dubbed the "World" engine. The Theta block is very similar to the Mitsubishi Evolution X 411BT, but the two engines are not identical. The Theta block is built with some lower quality components to keep the cost down. Some areas of note are the pistons, rods, and lack of significant webbing on the block. As of the Spring of 2009, this engine is still very new and it's limits have yet to be fully explored.

What is the maximum horsepower of the stock block?
According to Hyundai, 210 horsepower. The Aftermarket has yet to determine an acceptable "limit" on the stock internals.

What is the stock turbo model?
The stock turbo is a Mitsubishi TD04 model. In stock trim this unit pushes a peak of approx. 16-18psi with a sustained 14psi. This value can be changed with a boost controller and tuning.

What are the stock injector sizes?
The stock injectors are 330cc/minute.

What is the stock fuel system type?
The stock fuel system is a return-less system with a standard siphon fuel pump. This means that fuel is pumped to the engine only. There is no return line from the engine back to the fuel tank.
