Hi guys!
I'm just wondering what RPM are you getting when at highway speed like 120 kmh? My 73 with 285/75 tires is almost at 3K RPM. From there it feels like the engine likes to be on that range. I can pull and keep up with traffic easily and its happy to go 140 kmh/3300 rpm.
When I got home, i looked at the specs of the 1HZ, it looks like it is was designed to rev, not like a tractor diesel. All the engine torque at the low end and hp pass 3K rpm, 129HP is nothing to brag about but better than a mower engine. Transmission is geared for low crawl and highway speed, anything in between is hopeless and gutless until you get to 3K RPM. It's awesome to push how fast the old LC can go. Tires are howling but the engine is so smooth for a diesel.
