Ultimate engine weight thread

[ztunelover]

240sx from what i saw are king of engine swaps. So i figured this thread would be useful.

I havent weighed anything but the ka24de, but am hoping everyone can help out a bit. Dont leave out anything, nissan or otherwise.

Everyone needs to read this bitEngine weight is stated with alternator, ps pump, intake manifolds, headers/exhaust manifolds, turbo(where applicable), with flywheel clutch/ torque converter, fully dressed and without any fluids in the system. Transmission is not included

Its not mandatory to include engine dimensions but would be helpful, so if you have it you are welcome to post it in this order(Length X Width X Height). Units doesnt matter.

I made the restrictions to even out the field and reduce discrepencies as much as I can.

So here goes Nissan KA24DE(1995): 375~380lbs(the range in three separate tests)

Nissan VH41DE: 573lbs*33.5" X 26.75" X 29.9"*

Nissan VK45DE: 522lbs*36.25" X 27.25" X 30.6"*

Chevrolet LS1: 425lbs-

Toyota 2JZGTE: 535-550lbs(off local shop), 500lbs-

Nissan RB26DETT: 550-565lbs-

Nissan A12: 192lbs-

Nissan A14: 205 lbs-

Nissan L18: 260 lbs-

Nissan CA18ET: 260 lbs-

Nissan QR25DE: 267 lbs-

Nissan CA18DET: 282 lbs-

Nissan SR20DE: 306 lbs-

Nissan SR20DET: 328 lbs-

Nissan FJ20ET: 366 lbs-

Nissan VH45DE: 509lbs(ed300zx from skyline australia forums)

Nissan VG30DETT: 610lbs(Zgringo zdrive.com forums)

Nissan VQ35DE & VQ30DE ~330lbs-

http://www.35pickup.com/mulligan/weight.txt (provided by HoosierSX thanks man)

These two would be next to impossible to get but oh well for those who want to know.

Nissan VRH35Z: 408lbs(and makes 800ps to boot)

Nissan VRH35L: 375lbs(and makes 650ps)

Take that LS1

Note: The stuff that has a star beside them was information I got off the net. I did not measure them. So I cant stand by them. The two Nissan V8 weight and dimensions I got off racerx from the hybridz forums. Anything with the hyphens on them are the numbers that are posted below by the other members of this forum.

Well thats all I have for now. Advice on the structure of the thread is welcome. I will add all the information with acknowledgement on who provided the info in this post. I hope the mods or the admins sticky this, because imo I think this can be an important thread.

Thanks everyone & enjoy.

Fully dressed ls1 WITH transmission weighs like 575lbs. So 425-450lbs without transmission.

[brizanden]

nice thread added to my favorites just cause engine weights discussion comes up quote often. I always love how the ls1 weighs about 40 pounds more then a ka minimum lol.

[sean8564]

i weighed my 240 before and after the RB25 swap and the Rb motor was 20 pounds heavier than my KA

[brizanden]

hmm that surprises me cause the rb is cast iron block as well right? You would think since its a inline 6 it would be a bit more then 20 lbs over the ka, but then again its only .1 litre more so maybe thats why.

[HoosierSX]

edit...found some specs

A12____ - 87 kg _192 lbsA14____ - 93 kg _205 lbsL18____ - 118 kg 260 lbsCA18ET_ - 118 kg 260 lbsQR25DE_ - 121 kg 267 lbsCA18DET - 128 kg 282 lbsSR20DE -- 139 kg 306 lbsSR20DET - 149 kg 328 lbsFJ20ET_ - 166 kg 366 lbs

[sean8564]

Yeah i though it would be heavier but when i took it to the scales to see it was only a 20lb diffrence but i also had the Silvia Front as well when i did the swap and the OEM front with the KA

[Skilz10179]

I've read several places that a LS1 with trans weighs roughly 80 lbs less than a Ka with trans. I have never personally weighed either one so i can't know for sure...

[brizanden]

na generally i heard they are only like 20-40 lbs lighter.

[urcaptnspeaking]

yeah im pretty certain ls1's are lighter than the KA. my numbers could be a few lbs off, but not by much.

[brizanden]

i think we all just said they were lighter. Just they arent a huge deal lighter. The main point is that the ka is just a dam heavy 4.

[Flicktitty]

2JZGTE is around 518-528 Wet with motor mounts so say around 500 dry without motormounts.

[brizanden]

^well there is my reason for wanting a rb over a 2j lol.

[Flicktitty]

^well there is my reason for wanting a rb over a 2j lol.

curious, what does a Rb20,Rb25,Rb26,Rb30 weigh?

[brizanden]

i weighed my 240 before and after the RB25 swap and the Rb motor was 20 pounds heavier than my KA

so from that we make a simple algebra problem.ka+20 = rb. ka = 385 so 385+20 = 405. 405 is less then whatever the 2j was like 520 or something.

[sean8564]

the motor its self is 150 lbs or so more than the KA I found out. I think the 20 lb difference was when you add the weight reduction that I did during the swap like a Aluminum drive shaft Silvia Front body panels which is lighter than stock several other weight reduction things that is why it was only 20lbs i think. SO Just some clarification on the weight

so your saying it's gonna be in the 500+ range too then?

[sean8564]

NO 500 Hp not me and not that car. It is something like 360-370 Hp and that is all it will see from me. I spend too much on up keep of these cars except the R

?

i ment weight?

[ztunelover]

I think you meant ls1 without trans. the ls1 transmission is heavy.

LOL I was half a sleep But something like 500 lbs

[White Comet]

the t56 is a tank

[nxt774]

i think the original poster is trying to keep things factual not gestimates. the RB26 is around 550-565lbs complete just for reference.

[mattblancarte]

Yeah, the 26 is super heavy due to the fricken' iron block.

If you wanna save weight, build a solid 13b rotary and slap it in your car.

[ztunelover]

is the 25 or 20 lighter or heavier?

[sean8564]

the 20 is lighter due to the transmission mostly the transmission on the 25 is more like the size of the Z32 transmission and the 20 transmission is pretty much a KA transmission with a different bell housing

[simmode1]

VQ35de - transmission = 330lbs

Now somebody cough up VQ30DET specs....

vq35de is 330lbs without trans

this is not my pic I found it on the web

Edit: So... apparently, the VQ35DE and VQ30DE weigh the same thing, 330 lbs.

http://vq30det.com/phpBB3/viewtopic.php?f=2&t=21

But I still can't find the turbo'd version's weight. Probably a little lighter than a KAde...

i'll be starting on my 13bt project soon enough.

[urcaptnspeaking]

Ok the LS1 motor itself weighs about 450 lbs
