KA24e into a 620

[Bleach]

Icehouse originally had the 4x4 oil pan like you showed and that would not work. Get a 2wd KA oil pan if you can.

[Icehouse]

If anyone has a 4x4 single cam pan they want to trade for a 2wd pan I have one. I need a 4x4 pan for my truck now.... I should have kept the one I had...

[TrevDaddy]

Damn it was hard enough finding that one, and I didn't even know it was 4x4. The search continues. I think I should have just bought and L20 and built the shit out of it:glare:

I have a pan 40 bucks plus shipping

[TrevDaddy]

It'll fit my DOHC 96'? Will I have to modify the pickup tube and or cut the pan to make it fit in the truck?

[kaoss]

So what about the truck trannies? Here is what I have:

 

KA24e and 5 speed out of a 93 HB

5 speed out of a 77 620

4 speed out of a 77 620

 

The truck that this is going into came with the 4 speed, but I have the enitre truck with 5 speed in it.

 

 

EDIT:

 

Found my answer here:

just picked up a ka24 from a 91 240 sx. what is the difference between the truck and car motor? Did you have to use a pressurized fuel system?

[datzenmike]

Oil pans and intakes are different. You need a truck oil pan for steering clearance in your 620. The car KA has floating piston pins and main bearing girdle, the truck does not.

The DOHC pan fits fine. In fact it can be removed without dropping the crossmember. You have to flip the centerlink and clearance the pan a smidge for steering clearance.

 

I have 1/4" clearance all the way around at full crank. :cool:

 

 

 

You can see where I reworked the lower rear edge of the pan inside my sharpie marks.

Great thanks for the info. other than the oil pan it should fit just fine?

[Grey_Matter]

any info on the KA24DE into a 620?

i found one for 1000 with tranny and pieces to turbo it

its out of a 95 240sx

Well, you'll have to cut the motor mounts down. I used the same method as Icehouse. I dropped mine 5/8". The back of the motor (egr tube) is close to the firewall. I could have dropped the motor down another 1" and gained a bit more clearance back there, but it'll do.

 

 

 

 

 

 

I flipped the center link as I stated earlier.

 

I am running a 83 720 Z24 5-speed transmission, it bolts right up to the stock mount and the driveshaft slips right on. The shifter is in the stock location and the speedo screws right on. The trans is threaded for the starter. This required drilling out the threads on the starter making the upper bolt a bit hard to reach, but not impossible. You also want to make sure to use the truck slave cylinder, the car slave puts the hose right into the torsion bar.

 

Other than that it was a pretty straightforward swap.

 

 

Oh, I am using the stock 620 radiator. I'll post up it's effectivness after Canby. :)

awesome thanks man

[Creepy Cruiser]

Did you have to change the bell on the 720 trans to a KA?

[]2eDeYe]

It already has the gangsta lean, so it bolted right up. :)

[77DAT]

How about the wiring? with a fuel injection do i need a pressurized tank?

That's awesome,!

its not the tank that is pressurized it is the fuel coming from the tank that is. so simply using the fuel pump from the car you got it from should suffice, or you can also install an aftermarket electric fuel pump just dont forget to get an adjustable fuel pressure regulator

[]2eDeYe]

The 240 has an internal pump. You will need to get one that is an external, I'll post up the part # of the one I'm running at some point soon. Gotta finish prepping for Canby.

 

The wiring?? I had Icehouse come over and wire it up last night. He just started hacking away at the harness and after a couple hours he said 'Start it up' an it ran. I will say you need a bunch of wire, connectors, electrical tape, four fuses w/holders or a fuse block, 3 relays, some solder and a lot of patience. :lol:

 

 

Thanks Jeff!!!!

Thanks Jeff!!!!

 

 

No problem buddy!

Fuel pump I used was an Airtex E2000.

 

Double clamp your new fuel injection fuel line to the metal 620 line at all new line connections.

[datsun1320]

Hey man how did you power up the harnest

[Diesel33g]

Alright. So I've read all 7 pages of this and figured out everything that will need to be done (for the motor and welding etc, just gotta read that wiring how to now)

 

My questions are:

 

1. Which will give more power a ka from a 240? or one from the truck.

and

2. Which is more recommended, the 240 or the truck.

last one

3. How long was your 620 out of commission while doing the swap?

[izzo]

I think you should use the one from the truck, the ones in the cars are different. front sump vs rear sump, oil pump is located inside the timing cover on the car. Much better off with a truck KA, you can use the intake n shit off the car if you really want, and wiring harness i heard was better..

Okay thanks, I'll look for a truck motor then :)
