The stock mounts *should* work out ok, but you will need to make sure the brackets on the KA stay on the KA, and the Z and KA bellhousings are tilted differently-the KA leans to the driver's side of the car more than the Z.

 

Depending on your engine, pan, etc, it may be fine-as long as they tilt a little to the driver's side they'll oil properly.

Z and KA trannys don't lean differently. Guys use those transmissions interchangeably all the time without any lean. Z/ka is different from L but not from each other.

They are about 5 degrees different. Got all three out in the shop.

L 20 degrees counterclockwise
Z 5 degrees clockwise
KA 10 degrees clockwise

Is it a difference in SOHC vs DOHC?

Xnke you just solved why my tranny now hits the tunnel with a ka swap. I will agree the ka24e gives the tranny a twist from the z24.

I can't say that there isn't a KA bell that's the same as a Z, as I only have KA24DE bellhousings right now. It's entirely possible that there's one that's the same, I just haven't ever noticed.

You want an 8mm or 5/16" feed line and at a minimum a 6mm or 1/4" return line. If you don't have that, then yes, you'll need up upsize the fuel lines-on my datsun I kept the stock 6mm feed line and installed a larger 5/16" line, now the original fuel feed is the return and the feedline is 5/16". On customer cars I just run 5/16" fuel line for streeters and 3/8" or 1/2" for the racers, depending on HP and fueling requirements.

 

As far as fuel pump, Airtex E2000 is fine-and they're inexpensive. Readily adaptable, but make sure your line from the fuel tank is at least 3/8" diameter and picks up near the bottom-you do not want to run the inlet dry nor do you want to have the pump trying to "suck" fuel uphill. Make sure the pump is lower than the bottom of the tank (even if it has to draw fuel up the line then down to the pump) because you want to keep the pump inlet flooded.

 

They're greased to protect them on the first dry start-but the fuel washes that grease out and starting the pump dry will kill it in short order. This goes for any gerotor style pump, and most turbine style pumps too.

 

The 240SX harness-is it the complete car harness or just the engine harness? If it's the whole car...then I would start swapping out the harness from headlight to taillights! (that's part of what makes the truck harness soo good too-all the wires are long enough or too long for just about anything.

It's only the engine harness unfortunately

 

Have you tried installing with the stock mounts yet?

I haven't gotten to install anything yet. I have 2 more weeks at my apartment where I don't have space tools to work on it, so it's sitting for now, i'm just trying to gather as many parts as I can right now.

 

One more question. I was told that with a SOHC KA using a 240sx harness, you have to use an auto ECU if you put it into anything other than a 240 or else you get a 3k rpm rev limit. I've never heard this before, can anybody verify?

Hey guys long time no post. I'm actually putting this engine in my car and the stock motor mounts do not work. Has anybody done this swap and have pictures of what they did? If not, and I need to make my own mounts, what is the angle a ka is supposed to sit at, and which way does it tilt towards? (eg 10 degrees towards the driver side or passenger side or whatever?

Thanks in advance

L's are about 20 degrees to the passenger side from vertical.

Zs are about 5 degrees to the driver's side from vertical

KA's are essentially the same as the Z series for tilt. Someone said 10 degrees or 5 degrees more to the drivers side than the Z.

 

5 degrees over a foot, is about an inch and a half difference. On the transmission mount which is likely less than 6" from center line this would be 3/4". KA transmissions have been swapped into 720s without any bolt up problems.

The transmission mount isn't the issue since I'm using the same transmission I had. The part of the mount that bolts to the engine doesn't reach the rubber mount, they're too short. I figured out how much I need to extend it though, maybe I'll put some pictures up when I get it done

You want to make sure that the oil pan is level across the car. Tilt front to back is not as critical.

Are the stock mounts too tall? Why won't they work exactly?

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"
