J engine

Recommended Posts

Hello,

 

I recently picked up a 1961 PLG 222 pickup, but it does not have the original "E" engine and instead it has a "J" engine.  The engine number is J821462.  My question is what engine do I actually have?  I need to pick up a few parts at my local Napa to get her running, but I am not sure how to look up parts such as cap, rotor and wires.

 

Thanks,

Roman

Check the side of the block just under the head you will find 2 angular machined blocks one will have the engine model and the other the serial # of the engine.

The J series 1,300cc engine is similar and used in the '65-'68 520 and the first year '69, L521. This is the most likely engine that you have. The 411 also used a J13 in '65 or after but had dual carburetors.

Are you positive the J13 in the 411 had dual carbs, it had an R16 with dual SUs(carbs) in the SSS model, it seems like if the J13 had dual carbs I am positive that everyone would have been upgrading to them in the trucks, but that is not the case, I personally have never seen a 320 or 520 with the stock engine with dual SUs(carbs).

I do have 2 different assemblies to put dual SUs on my 320, but they are from MGB's.

No I am not. I knew about the 520 and the J series being knew in '65. Saw it listed as used in the P411 so wiki'ed it and said dual carb J13 but probably JDM market. I've never heard of it either.

411 had twin SUs on a model named ,   special,,  I believe .. I’m not sure if Japan only but I’m pretty sure never imported here .

 

my take..

520/521 guys were the poster child for being Datsun cheap till just a few years ago ,, so importing anything exotic would have probably been unthinkable ..

 I Was a “truck” guy and most of the guys I grew up with or hung out with were truck guys , and we treated them like trucks..

  we took engines out of 510s /610s to get a 521 running that we got cheap that owner had blew up ,, and junk the rest .

Just can't get my head around dual SUs on a J13.

Well I believe it is possible, but it will take some thought as the steering column is in the way, but if thin isolaters are used like the A series engines have I believe the rear bowl will just clear the steering column by an eighth inch.

It appears to be a J series engine, is there a 1300 cast into the side of the block?

I finally found it under the intake/exhaust manifold.  So when searching for parts for the engine I can use 1969 Datsun L521 with a 1.3L engine, right?

I expect so, it's not a popular engine so I don't know a lot about the engine itself.

I do know MGB distributors will bolt right in and I made an adapter plate so one can bolt an L block 5spd onto that engine.

Thanks Wayno.  I reached out to Moss Motors a few days ago, but I have yet to get a response about parts.  I would assume I can get MGB distributor at a parts store though, right?

You have a distributor, just replace the points.

I can start with that and see where it takes me.  Been a long time since I've had to mess with points.  Thanks datsenmike.

Count yourself lucky if it’s a J not and E as J points are same as almost every Datsun up into the late 70s .. E1 use weird points that are rather hard to source .. 

 

Which means you can install a pertronix that fits all those same models if you want set and forget type electronic ignition.

Honestly,, Points are very reliable and really only take a little more care than normal but not any more than those front drum brakes so it works out . and you can have extra new set in glovebox .. never left me stranded .

As much as I would have loved for the drivetrain to be original, I am somewhat glad it has a J engine in making it easier to source parts.  You did spark my interest in the Pertronix though bananahamuck.  Do you know how intensive of a process it is to convert?  I can probably still with my existing coil I assume?

I just converted my 411 (j13) in about an hour or so because had to solder wires to make longer to reach coil... if not for that it’s probably a 15 minute job taking your time . 
 

I had pertronix in my old 55 Ford for 10-15 years or more with no problems...  brother has had pertronix in his 510 since 2009-ish and never had to change out.. So I’m pretty ok with using them.

I think I will go ahead and give one a try...I do like some of the modern conviniences.  Seems like the "PerTronix 1741 Ignitor for Datsun 4 Cylinder" is the one I would order.

before you order,,,  maybe give a couple shots of your points as they may have used E1 distributor that came in truck ,,  and those are to different of a setup to use same pertronix.

I'm not quite sure I'm following you bananahamuck.  Are you saying that if in fact the distributor came from an E engine the PerTronix 1741 will have to be installed differently?
