There are companies that increase the displacement of your 3.4l (flat six innovations) and upgrade the internals but it appears that is a $15k endeavor. The chassis is not worth that investment IMO. I think I either sell the car as-is, buy a used 3.4l motor, or have mine rebuilt. I'm trying to figure out the best option and I need to determine who is qualified to build these engines. I want it done right if I rebuild....
