And now everyone wants a diesel or Toyots V8. Oh how did they ever win Dakar with a measly 4 cylinder?

What actually that was back in the day,,, was FrankR ( on 4x4WIRE)used Diamante block for his Supercharger project because it had boses on the block that added strength to block.
The 93-94  Diamante SOHC 6G72 had 10:1 compression and cams are timed to put power band at higher RPM .
I don't no if ECU will work properly.
Good luck and let us know about ECU compliance.
92-98 Hyundai Sonata used the same compression and cams timing as the 89-94 Montero.

I didnt put a toyota or diesel in. I kept all my original running gear except the motor (3.8L MIVEC).  :o

Thanks

Mostly bolt in. There might be some work needed to motor mounts, but its minimal welding.

The Block and Heads are the same , you would need to swap over the intake side and oil pan, plus all the accesories

If you are pulling the engine at a yard save some money and just take the bare block with heads attached (short block)
