also for any one that needs info or help let me know. i also have a spare engine and an intercooler and such. and it is not hard to pull around 400 ponies out of the ol mitsubishi motor either. the 2.6 was the building block for the lancer evolution. so there are plenty of options. hp performance is on that deals more with starion/ conquest engines. and yes the 88-89 is the best more because of the computer than the engine. either way you slice it its an awesome idea. my truck was built the 1st time by ken ellis sr. awesome ol boy that knows what he is doing.
