LS1 240sx

[turbojuiced]

I used to own a 240sx, and the engine is a big iron lump...

Same reason MR2 owners are swapping out their 2.0L 3SGTE's for 3.0L 1MZFE Supercharged Camry V6's: larger displacement at less or similar weight....

well if you did you would know that even though its cast iron the engine still weighs less fully dressed. The reason why mr2 owners are switching isnt because the engine weighs less its because the 1mz has bigger displacement and they come supercharged whereas alot of mr2 didnt come with the turboed 2L. Going from a 2L to a 3L has nothing to do with less weight but everything to do with more displacement and more power.

I would just buy a 'Vette if I wanted an LS1. I really don't care for the tone of most V8s(LS1 included) to be honest and wouldn't want that sound coming out of a Supra but that's just me.

But I can appreciate the effectiveness of the swap and understand the reasons why.

LS1 is probably the worst sounding V8, and that's coming from a guy that owns one!!!

 

[BlackSS]

Yeah thats why I mentioned the aluminum vs cast iron notion. But regardless its still not lighter. However, im not arguing which motor shouldve been used I am just saying that the ls1 is not lighter than a ka24. And the sr20 isnt the only engine you couldve used the rb series as well actually. But to each their own I guess and I have seen such a thing done before at D1 cant remember if it was a LS1 but it was a v8.

Fully dressed Auto LS1 = 457lbs (flexplate) Manual LS1 = 492lbs (flywheel and pressure plate)

I don't have any offical figures on the ka24, but I've seen 492lbs for the engine and 540lbs with the tranny on a couple forums by doing a quick search.

Don't forget, the reason he says it's lighter is with everything combined....which means you have to add exhaust manifold and turbo w/ piping and all....since the KA24 needs all of that to make similar power.

Yeah thats just the block and head

457 lb's for a complete Auto Ls1......

NOT just the block and heads.

Actually according to this link its 497.2 without drivetrain.

And according to different people the ka24de weighs in around 350-400unofficial however here are a couple links of some discussion from people who know about these engines.

lmao. Get over it - the LS1 is lighter than a turbocharged KA24.

1mz's do not come supercharged, they come out of Camry's, Solara's, ES300's, Sienna's, Avalons, RX300's and even Highlanders. TRD sold superchargers for them, and that's what's used. MR2's came with a 2L 3S-GTE or a 2.2L 5SFE (used once again, in Camry's, etc.). But most 1MZ swappers already have the 3SGTE...

well i know thy dont come supercharged. You said supercharged 1mz's so I made a comment about your particular comment. However, regardless there is no replacement for displacement. Thats why they use the 1mz over the 5sfe and sometimes the 3sgte. Most people actualy prefer the 3sgte.

Anyways, again to each their own.

i agree with no replacement for displacement, that's why I haven't gone (and wont) go 1JZ...

 

[x10secondzx2]

Bahh all this talk is boring me. I will have more pics tomorrow.
And turbojuiced...99% of stats on forums are from some guy who heard it from his sisters boyfriend grandma's ex-husband son.
Basically his car weighed about 2500lbs with his KA-T setup. When we go to the track tomorrow I'll tell him to weigh the car and see how much it is now.
I should have an in car 1/4 mile run and a drive by as well.

I second you on that but even the 4g63t isnt anywhere near 500# it is actually 350# of total dressed engine weight w/o drivetrain. And thats a turboed engine and if im not mistaken you were referring to the NA ka24? So Im just not seeing how this engine could weigh 200# more than the 4g63?

 

[turbojuiced]

Ok guys I did some searching and this si what I came up with. I did see some links where it said that the ka24 did weigh in around 540# however, that is with the engine and complete driveline including tranny, crossmembers and lines, rack and pinion, and everything attached to it. Normally the ka24 according to this official link weighs in at 394 which is approximately what I thought.

O btw the info is towards the bottom of the link.

I am referring to both. He had a KA-T set-up but a stock KA weights more as well.

My friend rich has 3 LS1 240sx's

That seems to be a bit over the top to have three 240's with LS1's. Why didn't he make three different LS1 cars? Unless he has one in a S13, S14, and S15.

 

[Big Wang Bandit]

One is his girlfriends DD.

One is his drift car

and one is another project that I think hes gonna sell when its done.

 

[RazoE]

Aren't you N/A ?

yeah, but I'm going 2JZ-GTE....:icon_bigg

I'm aiming for one of those NA->TT's everyone recognizes, just like OneJoeZee's former '92 NA->1JZ (RIP)...

O ok well the Ka series however you cut it does not weigh more. It has been proven through several links and with an official weight from Nissan. And as I thought the engine would not weigh 200# more than the 4g63 which is also a cast iron block. That just doesnt make any sense in the first place so its up to you to realize facts but denial is something different.

The facts are there its up to you to realize them and stop believing what you have heard or been told by others. Yes I found links of the ka weighing in around 540 but those were unofficial links from other car forums.

So again according to official links the ls1=497, 4g63=350, and ka24=397. You can add 25# for the turbo version and its still a whopping 75# lighter.

Or better yet I will put the ball in your court. If you can find me an official link from nissan as I did that says the ka24 weighs in around 540# then I am all ears.
