ka24DE 720 swap

[inda bebe]

i bolted on my KA24DE motor into my 86 720. so now, my problem is that i dont know what exhaust to use. i bought a 240 hotshot header and i didnt fit cause the torsion bar is in the way. i put the stock ka24de exhaust manifold and the frame gets in the way. whats the solution?

custom exhaust mani.... or a turbo, with custom exhaust :rofl:

What oil pan did you use? I would get a 240sx downpipe and modify it to fit around the torsion bar, or make a flange and a single down pipe.

I used a modified 240sx pan. The previous guy had it mounted on a hardbody, so when I dropped it into my 720, the pan still sat on the crossmember, so I have to mod the CM a inch or two lower. But, the down pipe isn't a bad idea. I was just gonna use and chop up my hotshot header and custom everything else

Because the DE was used in the '98 and up D21 Hardbody, maybe they are designed to clear the torsion bars. I'm not too familiar with the latest Nissan trucks. Someone?

[inda bebe]

No, removed it.

I used the stock manifold in my 620 and had the exhaust shop make me a new downtube.

I'll just this and shorten it, then have them custom the down pipe.

Never knew this swap required a lot of welding from the 240 motor. I found this motor from a guy who had it modded into his d21, I thought his mounts and oil pan would fit perfectly into my 720. I was wrong!

 

For anyone else planning to do this swap, please consider the frontier motor.

So, knowing what you do now, why not get yourself a Frontier pan and put it on before you go any further? That way you don't have to mess with your x-member. What about an exhaust manifold off the Frontier as well?

i think the frontier pan has a different bolt pattern than the 240sx. plus, ill get a stronger crossmember made than the OEM. as for the exhaust manifold, im trying to find one. i already have the KA24E thermostat housing for the power steering delete, cause the power steering was in the way.
