If Airtrek is made so similarly to Evo, it will hit it's own product line. That is why Airtrek is a 'detuned' version of Evo tho the engine block is 4G63T. What I am modding now is actually upgrading the parts from Evo into my Airtrek to have similar performance of a STOCK EVO! That's sad right? Pain in the arse.
