Engine weight?

[Lynxkcg]

Anyone happen to know how much a CA weighs? Or any of the swappable engines for that matter?

I can't really imagine a CA weighing more than a KA, and even if it did, these sit farther back towards the firewall don't they?Thanks!

did you search? o.O

[capwred]

yes please serch because this has been talked about alot.

but i will tell you this.the weight of the ca is less then a ka and a sr.

[tyrannix]

i posted a pretty long list of (damn near) all nissan 4 cyl engines and their respective weights, search the 240 forum

I don't know if the CA is less weight than the SR. Aluminum vs. Iron. It isn't that much larger in displacment to be heavier. The KA is heavier than both, and the RB's are slightly more than those. For the power-weight ratio, any series of engines are great! GO FR!

I think the moderators should add a thing that automaticly says. "search for it" to save all you guys the time it takes to type it.

a ca weighs 269 pounds (122kgs)and i was todd that the sr was about 295and the ka was around 310

That just means you need thicker aluminium and more re-enforcing to make it as strong as a cast iron block. Also an SR had a timing chain which would way a bit more than a belt and also the extra parts in the valvetrain.

a bit of fuel to the fire...

stolen from a similar thread elsewhere

"Nissan Fast says both engines weigh 95Kg bare. That's everything between sump and rocker cover but no manifolds, plenum, turbo, alt, flywheel, steering pump, etc. (not too sure if it includes water pump, ignition)

Flywheel CA 12.3 - SR 8.9Front pulley CA 3.231 - SR 2.45Oil cooler CA 1.55 - SR 1.315Plenum CA 3.4 - SR 2.778Inlet manifold CA 2.081- SR 3.661A frame etc CA 2.6 - SR 0.84EGR SR 0.63Alternator CA 5.46 - SR 7.523Starter CA 3.392- SR 3.1Clutch + cover CA 6.63 - SR 7.9engine mounts CA 1.5 - SR 1.1engine plate CA 0.735

CA 42.8 - SR 40.2

Totals according to FAST CA 137.8Kg SR 135.2Kg+ assorted gaskets, hoses, water tubes, hose clamps, nuts and bolts which all add up and still without power steering pump, and A/C."

for what its worth

CA bare block (with oil squirters, no endcaps) weighs 76.4 lbs

1 stock rod+piston with bearing +studs is 3.2 lbs (x4)

head with cams and covers +bolts (no head bolts, sparkplugs, garnish or manifolds) 49.4 lbs

this is all seperate stuff in my garage that i put on a scale

the rest of the spares are buried (stock plenum, crank etc) ill update this when i weigh them. or even better ill weigh everything as i assemble the next engine and make a new thread about it

The general weights of all 3 of the main 240SX swapped motors (KA24DE, SR20DET, CA18DET) are all very close to eachother due to many factors. The KA may seem lighter because it dosn't have all the turbo parts, but it also is a bigger motor, which will weigh it down. The SR may seem to be the lighter motor, but it's also turboed, and has the whole timing chain and rocker arm setup which weighs it down. And while the CA may seem to be the lightest because it is so small, it also has a cast iron block, a turbo, etc. In the end the weights arn't that much apart from eachother and IMHO shouldn't be a factor when considering a swap in your 240. Just my 2cents though. You also have to consider wiring harnesses, oil and coolant levels, and all that jazz.

I disagree.

[Sil40sK]

I disagree.

Thanks for that informative post.

EDIT: For the record, my CA with the trans weighed 440lbs on a wooden pallet, so it's probubly about 430lbs minus the weight of the transmission.

[datsunboy]

I also disagree.....the CA is significantly lighter than a SR, and depending on what sort of car you are building, then weight should always be considered.

[davidricardo86]

I agree.

[float_6969]

Although I have no definitive, concrete evidence, I CAN tell you that when I pulled the KA out of my S13 and swapped the CA in, the front of the car now sits CONSIDERABALLY higher than it did.

I PROMISE you there is some sort of measurable weight difference between a SOHC KA and a CA.

i disagree, even a half pallat is going to weigh more than 10 lbs

i have a half pallat that my donor ca20e is loaded on, ill post that up as soon as i unload it bfrom my truck (meaning when the s13 moves out of the garage under its own power and broken in)

Yea, pallets are kinda heavy. I'd put most of them at about 20-30lbs. There is a lot of wood that goes into one.

[Zero260]

i deal w/ pallets all the time(regular sized). they have a big range in weight to them, I've grabbed some that were about 25lbs.(made w/ a darker wood.) and I've grabed ones that weight about 10lbs(made with a lighter colored wood.). so factoring in pallet weight will depend on each pallet.

[float_6969]

BUT, 10lbs in the scheme of things isn't that big of a deal.

I disagree. The Northern Red Oak tree has a light hue to it but is able to be constructed into pallet of formidable weight.

CA is definitely lighter than an SR, ive got an SR bare blocka nd a CA bare block at my disposal the CA block is lighter... imagine that, oh yeah and its MUCH smaller
