Which engine is this!?

[red_dog007]

Well, my boss/friend owns a Datsun pickup truck. I am not sure what kind, year, or model.

Though, I popped open the hood and was rather surprised at what I saw. At first, I had thought that it was a V8. Spark plug wires were traveling to both sides of the engine, and the dizzy had 9 plugs in it. I was shocked to notice a Datsun with a stock engine (I do believe) with a V8 in it! So then as I investigated even further, I only noticed exhaust and intake only going/coming from 1 side.

So then I was even more surprised to know that this had two spark plugs per cylinder which is rather surprising now that some auto companies are starting to use 2 spark plugs per cylinder now.

Which engine might this be? I would like to know a little more about this guy.

My guess is it is a CA20.

SOHC, 2000cc twin plug slug:rolleyes:

Most likely a datsun 720, pick-up truck. They came with a NAPS motor. (Nissan Air Polution System) it has 2 spark plugs per cylinder and 2 coils. It's your basic Nissan motor for that style truck.

I used to have one, It was an 82' 720 truck.

It would be a Nissan Z series motor. Like a Z18 or Z22. google it.or wikipedia.

They didn't use the CA's in the trucks here. More than likely it's a Z22S or a Z24S which is the NAPS engine. It's also a 'twin plug slug' as you say. Built more for emissions compliance than performance. I had a 1980 200SX with a Z20E. Same engine except smaller and fuel injected. By the way Dave, NAPS stands for Nissan Anti Pollution System not Nissan Air Pollution System.

My 85 720 4x4 had the Z24 with the duel plugs if I recall correctly

By the way Dave, NAPS stands for Nissan Anti Pollution System not Nissan Air Pollution System.

Yah Yah Yah, you say potato, I say AIR.

I stand corrected.

Dave.

Nissan Anti Potato System?
