Any Disadvantage Using An L24 From A 240K?

Recommended Posts

I've been chasing a decent L24 to replace my JDM L20A. One has come up but it is an L24 form a 240K. Is there any disadvantage to not having one that came from a 240Z? I've read that the position of the bowl sump is different (K's have front bowl sumps, Z's rear). The set up I'm looking at also has an N42 head, which I don't think came stock with any 240K's.

Cheers.

Hey mate, Can't help you with this question but I was actually wondering if you had a rear oil sump pickup from your L20?

 

Cheers!

Do you mean a spare one? The only oil sump pickup I have is in the engine that is currently running in my car (Which is definitely not front, most likely rear, however it looks just a little forward of the rear).

A 240K L24 won't bolt in without oil-pickup mods.
You'll have to remove the sump, the oil pump & timing case, then the rear oil pickup boss needs to be drilled & tapped.
Then you have to back flush the oil gallery so that no swarf/grit can get into the oil pump & ruin the engine. Then reassemble with your Z sump & pickup.
Then cross your fingers you've gotten all the swarf & grit out...

 

IMHO, You're better off finding a L24 out of a Z.

Yeah, I'm just after a pickup for the rear sump oil pans. 

 

Here is the "front sump" oil pan

And here is the one that I want a pickup for (from an L20ET)

Let me know if you decide to tear down the motor and don't need your rear sump pickup anymore haha

 

Cheers,

I looked at that K engine option myself years ago, and as others have said the K oil pick-up, sump & dipstick location is different .

Also, the K motors I saw looked to have smaller ports, manifolds etc, one had a large single carb not pair; so I presume were lower-HP engines, no doubt there were different versions for Ks and K-GTs and markets or whatever.

Some work to alter for your Zed, and which N42 head is it . I could be mistaken but am pretty sure a spare head I have here - an N42 - came off a K engine.

Probably not worth the trouble better to find the right one.

Don't think N42's came out on 240k's. All the ones I have seen/had where E30 as listed in the Pinned post about heads. Smalll ports. Any chance someone has swapped in another motor into that K?

240k's also have dished pistons standard, so if you bolted a head on with a larger chamber than the E30 the compression ratio would become very low from the 8.5 to 1 stock.

Going by the sticky you are right, engine was removed from a K but must have already been a transplant. Odd.

So not much point in putting a K engine in if it's all small port and low compression.
