Hey guys, This is my first post... How hp friendly are these cars? At what power level does the transaxle fail? short block? What are the upgrade options? I know this is an open ended question but I am only familiar with muscle car options... i.e. ford 9" rear with 4l80E auto or T56 manual.

Reason I ask is my wife has a '95 240 SX SE that just feels more nimble than my bird due to its lower weight and better suspension. I am just contemplating boosting the power

Thanks a lot,Andrew
