Whats an average life span of an RB20DET usually expected to be?
I realise there are a lot of variables which will increase/decrease the life span of the engine,
but if everything was pretty well stock, what's the most Km's someones got out of one of these engines?
I'm looking at a care today that has 155,000 on the clock, it a 93 R32 type M, that seems a tad high....
