My Nissan Pick-up D-21 has over 140,000 and it runs great. It still has good acceleration it never over heated on my Grandpa or me. I take it down the hill in high heats and it doesn't even come close to overheating. We got it from my grandpa who passed away a year ago. My dad was driving it home one day and it just quit running. He started it back up and ran for a couple of seconds and died; so he started back up again and barely pushed on the gas and kept it running. He drove it until the tags expired and it sat for two years. So I said to my dad, "Can you go get me some starting fluid so I can see if it has an intake leak?" So I got in the truck, started it and kept it running at one speed. My dad sprayed starting fluid by the intake and it picked up idle speed. So we ordered the gasket; I put it on and started it up. It runs great. I was happy. Since I fixed it it runs like it was brand new.

The engines used in these trucks are the same as the 240sx which is often used as a ricer/racer. They are very hardy engines. The fastest I got my truck up to on a hill was 90-95 mph. I'm not entirely sure which because I was more concerned about driving than how fast I was going. The Amazing thing is that it took the highway really well and wasn't bouncy or uncontrollable at those speeds. The engine was roaring a bit, but it handeled it well. I wouldn't recommend driving at these speed frequently but it is cool to know that you can do it. And on another note the truck could have gone faster than 95 if I let it, but I thought it would be unsafe. :D.
