Well.....
As far as miles the highest one I know of is John Nagels Gn in Stockton Ca. It has over 500K on it after two motors, two trannys and a rear end I beleive. That is the highest milage daily driver I have seen. I do not think he races it but the street is alot tougher on them. This impressed me.
As for my WE4 it has 292,000 miles will run 11.95 or better with a 1.70 60 ft with the original inj's, original turbo, (rebuilt once just for maintiance,) original short block, and only things I have changed internally would be valve springs twice, and a timing chain, double true roller installed at 160,000 miles.
Oops, I forgot, I installed the oil pump hi volume kit when I did the timing chain. Even with 292K on it it holds 40 psi oil pressure at idle hot and 75-90 cold.
I also drive this car hard so it hasn't been an easy 292K. LOL :biggrin:
Second tranny, and second converter. First trans went at 120,000 miles and the second is still in there and still barking third gear. Ask anyone who knows the car.
Original rear end.
Needs a rear end now I think tho, as it is making funny noises at times.
All in all, impressive.
