Can you identify this engine?

Can anyone identify this engine?

The only clue is the embossed words on the cam cover:

"Twin overhead cam 24 valve"

looks like a Naturally aspirated 1JZ (maybe 2JZ) Toyota inline 6.

That's what it is.

Don't think so, it looks old, don't even look like the M series.

Is that distributor I see. ?

Thanks for your feedback.

The engine is installed in a Tata Xenon single pickup 2010 model.

The original vehicle had a CNG system.  This has been removed (including the gas cylinder) leaving only the original reserve gasoline tank which holds about 15 litres.

Has anyone had experience with this engine?

At present It's so out-of-tune that the vehicle is almost impossible to drive.

It's seems to be flooding, a lot of petrol smell and popping sounds in the exhaust.

When I floor the accelerator, it bogs down with a sound similar to a Mac truck decelerating.

When I try to take off into traffic there is no power at all and the car basically slows to a stop.  If I gently press the accelerator it can reach a sweet spot and begin to move the car and with gear changes I can get up to speed.  However if I try to speed up quickly, it behaves the same and bogs down with now power.  Hopefully somebody will be able to give me a few tips on how to get it running well enough (to drive to a mechanic that knows what to do).  I am using 95 octane at the pump.

Could be that the timing is massively off ?  There are tools to check for that but I assume you dont have them? Try losing mounting bolt/s and rotating the distributor a little one way or the other.  If it improves go a little more that way - find the sweet spot if you can. If it is worse, then go the other way.  Turn engine off each time - dont do it running - too many things can go wrong.

That's ok, I know that it is!  The JZs are pretty old now!

One positive point is that there is no blue smoke from the exhaust !

There is a socket labeled "diagnosis" so I am hopeful somebody will have a suitable instrument to give a more accurate proof of what needs work.

I would look for an intake leak - symptoms described fit that to a Tee

A few more pics of the engine. Note the "no name" camshaft cover. Probably had a Toyota sticker originally.  Note the gear lever alterations and makeshift boot.  I will listen (with a bit of hose) to see if I can detect a leak around the inlet manifold.  If there's nothing there I will try moving the distributor slightly. I have a timing light but it's buried deep in a storage trunk with some stuff I brought from Australia (that's another long sad story). 

Can you imagine the bad looks when I drive into a Toyota service centre?

"No have! Mai me! and No can do for you, ha ha!

Once engine warm, you can spray WD40 around any areas you can't see. If the idle speed increases, you have found a leak.

If that don't help, could be a MAF, TPS, or the wiring connecting them to the ECU.

If I had to bet I would not think it was ignition related.

But I been wrong before !
