i talked to a ref and after talkin to him the only prob i see is the fuel system..( if you have an obdII car )... its way easier to bar the car if the car is obdII if not then its going to be even harder..... the ecm has to be a us ecm so for k20a/k20a2 us type s ecu is needed.....immob is the next problem..you cant just remove it b/c it causes a check engine light....i found some loops holes so ill let you know how it goes! ( fingers crossed ) oh yeah the only way as for the intake is using an intake for the car the motor came out of..like an aem or injen aftermarket carb legal intake and also as for the header......cant use a dc sports tsx header b/c the carb number on the header has to match the motor..( and they check ).unless your using a k24 outta tsx..
