This is something I have been chasing down. I have a completely stock 1.8 with L-Jet. Up till a few weeks ago it ran a little hotter, but a fixed leaking Retard Vacuum canister brought the timing into spec. Now my freeway heat is dpendant on a few factors;
1) Heat of the day, 2)Length of freeway run, and 3)How hard I ran.

Freeway driving at normal speed of 65-75 for 30 minutes. Flat, one or two small hills.

on a 90 degree day I get to 220 on the freeway, but once off the freeway and in town right away it goes up to 230.

On a 70 degree day I get to 210 on the freeway and up to 220 running in town after the freeway

On a 60 degree day I will see 195 on the freeway and 210 comming into town.

If I never go onto the freeway and just drive around town for 30 minuts my temps seem to get to about 210 or 220 on a 75-95 degree day.

From a lot of othersI would say I am running hot. But my mechanic says its just fine. I live in the dry desert at 4,000 feet with an average temp of 80+ degrees. In the summer we can see 100+ for a week or so.

AND: I use a brand new Electric VDO gage and sender in the Taco plate. A battery operated Voltage Temp gage Thermocouple down the dipstick, and an infared temp gun to calculate the temps. I calibrated/checked them all with a pot of boilg water and a cooking thermomiter.
