I need some advice from the 4runner masters. i found a 2000 4 cyl. 5 speed, with 230k miles on it. It also has a TRD/ alpine supercharger installed that was put on with 180k on the engine. The 4runner is very clean, and has lots of goodies, but I am wondering if it's a real headache with so many miles and with the s/c installed. Does the s/c kill engine life? How much longer could I expect the engine to last? Is it just a bad deal altogether? Thank you.
