3FE vs 2F spec sheet

[slcfj62]

Found another interesting bit from the 1988 new model features document from Toyota. It's a bit hard to read, but the columns under the 2F that don't have a number have a little arrow pointing over to the 3FE column which I would assume indicates no change. And the lower right column that is goofed up by the mud icon reads 200 ft-lb @ 1800 rpm.

200 ft/lbs at 1800 RPM? That's almost diesel...

3FE appears to have 210@2000, just not the peak point

After looking at that sheet, I suddenly feel very comfortable with my 3FE...

190 ft/lbs @ 800RPM

Someone find one for the 2F-E?

Pull it out and take it to a dyno Failing that, we only have Matt's #s to go on I suppose.

Someone needs to build a 2FE out of straight Toyota parts and dyno it. That'll give us a baseline, since Toyota never officially sold the motor.

I've been wondering what a typical 2FE puts out...

How common are motor dynos as compared to chassis dynos? I eventually want to build a 2FE, but it won't be from unmolested parts.

You will molest your parts before building?

Yep. It's a pretty flat torque curve. I think it is a great engine.

I'd love to put it up on the chassis dyno to finish tuning it up. I think it could run much better with some work.

Is there something magic about where the torque line and the horsepower line intersect? For the 3FE this happens at about 3000 rpm. Is there such a thing as a sweet spot?

 

[matt.mcinnes]

First up the spec sheet for 2F and 3FE in the first post is incorrect.

This is right.

As for what a 2FE can do hmmm

My 2F-ETI in RED not real a base line though The one in Blue is a 4.2 Ford Maverick Turbo Diesel.

But it should look like this.

No, they are on different scales. But torque and HP always equal each other at the same rpm (~5300 IIRC), as HP is a function of torque (force) and rotational velocity.

That said, I've always found mine "wakes up" as it passes through ~2500 rpm.
