As far as revving your engine goes, there was the time I had to drive home with a broken trans, hockey stick snapped, got the trans in 2nd gear and drove some 70 miles home, 152, 99, 180(CA highways, Madera to Fresburg). Kept up with traffic the whole way, actually hoping to blow that engine so I would have an excuse to rebuild it. Drove that Celica 2 more years after that. Ended up junking the car because I found cracks in the chassis, but the engine still ran strong. That car turned the clock over several times after I got it.
