Thread: What to look for in a Isuzu 110/Stage 1?

I think there are several reasons for that -

1. The Series mudguards are less of a sound shield than are the double ones on the 110.

2. Most 110s have at least some insulation.

3. I remember being told years ago (by Fred Smith) that the engines fitted to the 110s had a slightly lower compression ratio, I assume with a different head gasket, to reduce the knock.

They're not hard to hook up. I use the factory one in my rangie driven from the alternator.

From a sample group of two (I know it's not much to go on), but the engine in my Stage One Isuzu, has much more of a diesel rattle than my 110 Isuzu.
Bonnet up, standing outside the vehicle, there is a considerable difference.
Both have about the same kms on them

The Stage One also pulls much harder, but I'm guessing that's probably more a function of less weight and lower gearing.

Cheers

Injection timing?

So what high range ratio did the 110's run, and how hard is it to find one of those gearsets and swap it in?

Could be.

When I tried to check the timing on the 110, I removed the cover rolled it over but couldn't find the mark. Gave up in the end, and as I was getting the injectors professionally, done asked them to check the timing.
turns out they couldn't find the mark either.
Looks like I'll have to spill time it, but since it runs well enough I haven't been motivated enough to do it.

Shouldn't you be looking for the mark on the front crankshaft pulley? They're the ones that are graduated with degrees. The one on the fuel pump drive gear is only to make sure it goes in lined up correctly.
