High Mileage 7's
Who's got the high mileage champ on this board? My '85 FB is just turning 100,000 miles and I am interested in hearing how long I have before I start to experience the need for a rebuild. Who's got high miles going for them?

178,000 miles, 12A with dowel pin oil leak...still stock, unopened, slight smoke at start-up, goes away in 5 minutes, passed inspection, idles at 550 RPM, revs to 7600 rpm, dyno'd at 7200 rpm steady state, still OK, I reckon, gets 17.5 mpg with unrebuilt Nikki carb and stock exhaust...

100,000 miles is young for a first gen, I've only had one below that, my white 84 GSL, which had 82,000 when I got it a couple years ago and is now pegging 127,000. The others:
The brown 85 GLS, 178,000 (retired, good engine)
The tan 84 GSL, 148,000 (retired, good engine)
The silver 85 GSL, 106,000 (the future, great engine)
When I first got into RX7s about 7 years ago, I figured I'd be having to rebuild an engine, probably sooner than later, but it hasn't happened yet and I'm guessing it probably never will.
My friend Mike has 240,000+ on his 85 GS(L) and it runs great, still on the original engine.

I got 242K on my GSL-SE. Untouched engine and transmission, but a lot of the other stuff has been fixed at some point or another. Before I started driving it last year, it had pretty much been used solely as a commuter since it was bought in '85 and has been totally babied...
