Hi, I'm a novice to the RS Generation, picked up an '88' S2, requiring serious attention, already fitted with dump valve, SS exhaust, turbo as standard, hydraulic tapets are a bit chattery, dent in the fuel tank, prior owner being running on leaded, requires welding NSR chassis mount, bodywork and interior pretty much standard, generally the cars running pretty crappy, but i need to have an idea how it should be and don't know where to start first.
