Welp.... With the price of SR's I've went to the dark side......

Hmm. Heavier than the SR which is pretty weird. SR has a heavy stock flywheel and heavy stock exhaust manifold. So it's could be even lighter.

What a proper engine weighs

[510rob]

Datsun L16:
317lbs = 144kgs

Nissan SR20DE:
329lbs = 149kgs

Honda K24:
338lbs = 153kgs

I like this thread.

The K24 is a bigger engine, makes sense it weighs a little more. Thanks for the weights.

Perhaps the 1600 valve cover is misleading, it is a Z-22 block. The L-16 is not 144 kg, don't remember but think it was somewhere around 130 kg.
Of course for the most precise result should all weighing be done with the same flywheel/clutch pack.
Or even better without it, then the variation in flywheel/clutch weight wont give misleading results.
Very long time ago i weigh some parts.
L-13 bare block 32,8 kg
L-18 bare block 40 kg
L-18 bare block 86mm bore 38,6 kg (i remember the block's could vary a 2-3 kg, so what this could weigh before the 86mm bore i don't know)
Z-20 bare block 42,4 kg (with bearing caps 46,5 kg)
Z-24 bare block 45,2 kg (two block's weigh the same)
To bad my notes not telling if it was with or without the bearing caps, but the Z-20 caps with bolts are 4,1 kg.
L-18 block with internals (four cw crank) 60 kg
LD-20 block with internals (eight cw crank) 69 kg
Z-20 block with internals (eight cw crank) 70 kg
This was my notes i could find.

We weighed our L18 that we never ran. It doesn't have carbs but those don't weigh much

[shlammed]

Still heavy enough when im deadlifting it trying to put it on an engine stand LOL.


Excited to see how you guys make out when you get your first few track days in with this swap.
