engine swap

Hey guys,

Someone on here posted a diesel swap of a Mitsubishi or Isuzu into a late model Chevy P/U. Could that person please repost that for me???

I have another 300SD that I plan to use the engine and trans in the swap, but the post I read they were getting 38+mpg in there swap.

Thanks Doc.

That engine does not even get that kind of fuel economy in the original car, why would it in a less aerodynamic pickup?

Lol 38mpg. Try half that.

In a pickup depending how horribly un-aerodynamic it is and how heavy, you might be able to hope for 19-21 mpg.

Right. The thermal efficiency needed for the engine to get 38mpg simply isn't there, especially in a 5,000lb+ body on frame brick that is a Chevy.

The only way you'd come close to seeing 38mpg with an SD engine and slushbox is to put it in something very small and light. With a pickup you'll be lucky to see 19-21 as pawoSD said.

Sorry I got the MPG wrong it was 32 with a 5 speed in a full size P/U.

Yeah, when the very first words of a website are "ORDER WITH CONFIDENCE" I tend to be a little skeptical of their claims.
32mpg is still extremely high for a pickup.

This is a much more believable claim from their website:

He drove the wheels off during the next 10 years, pulled an RV mostly, never put a wrench on it, got 22 mpg (no overdrive), sold it and it is still on the road today. I have used other makes but Isuzu is my first choice.

Only 200miles of driving is NOT enough to make an accurate MPG claim. That highway stretch is likely going down in elevation to get that kind of economy in a brick so MPG going the other way and an average of the two would be needed to get a reliable figure. He also doesn't supply any fuel data (gallons consumed, etc) to back it up.

Considering he is trying to sell his product, he would be much more inclined to embellish his figures to increase sales.
