I am considering building a 2.1 long block with some minor performance

since I  am just over 150K on an untouched motor.
The question:  How much can my stock 1.9 fuel injection handle?

  The Digijet fuel injection system is not what is limiting the available

that darn rev limiter that's built into the ECU.

I have been wondering, now that the engine I bought from you has a few
thousand miles on it, what is a reasonable rev limit for a stock 2.1?  Mine
has the longer duration cam, if that has any affect.

So far, I have been trying to stick to about 4200 RPM Max on the highway,
the top of the green stripes.  That's an indicated 70 mph on my '87
Westfalia.

Grinding up hills in 3rd, it's about 52.

The engine willingly revs a lot higher, but I have been cautious.  Most
likely 10 minutes going uphill at 5000 won't be any problem.  What do you
think is a reasonable limit, for how long, and why?

Thanks!
