Acardiel11 Posted September 26, 2017 Report Share Posted September 26, 2017 How's it going y'all! I need your guys opinion on this one. My buddy has a buddy that's selling KA. It came out of a 1990 Nissan 240 and he's selling it for $300. Here's some pictures. Maybe you guys can give me some more info on it or if it needs anything else. Thanks in advance! 2 Quote Link to comment
racerx Posted September 26, 2017 Report Share Posted September 26, 2017 How many miles? Did u hear it run before it was out? 1 Quote Link to comment
Moist Lightning Posted September 26, 2017 Report Share Posted September 26, 2017 Just do a compression test. Even a cold test should show any problems. 1 Quote Link to comment
Acardiel11 Posted September 26, 2017 Author Report Share Posted September 26, 2017 How many miles? Did u hear it run before it was out? He's not sure on the miles. I guess he picked it up from some who did a swap. It was running before it was pulled. I didn't here it but he said it ran good. But that's what they all say. Haha 1 Quote Link to comment

Draker Posted September 26, 2017 Report Share Posted September 26, 2017 Will need ECU, coil, MAF. Do a leak down test. That will tell you all you need to know. Plus easier to do than a compression test when mounted on an engine stand...... 3 Quote Link to comment
distributorguy Posted September 26, 2017 Report Share Posted September 26, 2017 All that Plus exhaust manifold. Compression test above 150 is great. Below 125 not so good. 1 Quote Link to comment
Moist Lightning Posted September 26, 2017 Report Share Posted September 26, 2017 Personally have not done a compression test but will look up how to do it. Any specific numbers I'm looking for? Temp and elevation effect compression numbers. don't worry if they are lower that spec. my de was 145 +/- 5 psi on all cylinders cold at 3000ft. Look for consistency in numbers. also 2 low numbers that are the exact same and right next to each other indicate head gasket failure. Compression test is cheap and easy. if comp is good and you are still worried look at a leakdown test. Edit: you can "wet compression test" to look for cylinder or ring wear. 1 Quote Link to comment
datzenmike Posted September 26, 2017 Report Share Posted September 26, 2017 So no one has seen it run? Only the price is right. Car KA are heavy and front sump. Hardbody engines are lighter and rear sump and a better fit for the 620. The car electronics can be swapped and are a separate harness than the D21. You need a flywheel and a transmission. 1 Quote Link to comment
flatcat19 Posted September 26, 2017 Report Share Posted September 26, 2017 Offer 2 for the single. Offer 3 for the DE that's sitting on the ground next to it. ECU, harness, coil, trans. Does this motor come with any of those? 1 Quote Link to comment
KoHeartsGPA Posted September 27, 2017 Report Share Posted September 27, 2017 If you get the ECU and harness call it good, go find a d21 running KA do timing chain kit & gaskets, put it in a Datsun, go have fun. 1 Quote Link to comment
KoHeartsGPA Posted September 27, 2017 Report Share Posted September 27, 2017 Oh and you'll need Steve's bracket for the fuel pump, motor mounts, and get Jeff's Can-Am box for plug & play onto your 620, all that will save you tons of hours in Fab work and wiring! 2 Quote Link to comment

Lockleaf Posted September 27, 2017 Report Share Posted September 27, 2017 To use that ecu and harness will also require the intake manifold and injectors etc. 240 is mpfi d21 is tbi. That engine will cost you another $300-500 to get everything you need just in parts for it. Not including swap brackets or wiring boxes. Better bet is to buy a running 2wd 1990 or newer d21 beater for $800. You can know condition of the drivetrain, you have every part necessary to make it run and its the closest to fitting your truck you can get from one single vehicle. The harness is the worst part. D21 engine harness is part of the complete vehicle harness. It can be separated though it isn't fun to do. And it will cost the same as what you are looking at and have huge advantages over piecing together a drivetrain 1 Quote Link to comment

datzenmike Posted September 27, 2017 Report Share Posted September 27, 2017 Car oil pans are deeper at the front and a truck steering won't work with it. The oil pan needs to be deeper to the rear where it is out of the way. You can't just slip a truck D21 oil pan on to 'convert it' because a car KA also has a large heavy crank girdle that interferes with a modified oil pan. Anything is do-able, but a Hardbody truck engine is just easier to fit into a truck. In addition the car KA is a much heavier block. 2 Quote Link to comment

Acardiel11 Posted September 27, 2017 Author Report Share Posted September 27, 2017 Thank you all! I think I may just pass on this unless I can talk him down. 1 Quote Link to comment
datzenmike Posted September 27, 2017 Report Share Posted September 27, 2017 Well you will need a Z series front case for that transmission if you want it to fit the KA. 3 Quote Link to comment

KoHeartsGPA Posted September 27, 2017 Report Share Posted September 27, 2017 Thank you all! I think I may just pass on this unless I can talk him down. Try to get the complete intake+wiring harness+ECU, those are vital for the swap 1 Quote Link to comment

I wouldn't let something so trivial get in the way of buying a KA. 2 Quote Link to comment
datzenmike Posted September 27, 2017 Report Share Posted September 27, 2017 Left is front. Top is 240sx oil pan. Bottom is D21. Below is the 240sx oil pan. Front is to the right. Note how deep it is even at it's shallowest. This is so it can cover the internal crank girdle, missing on the D21 block. The D21 is much thinner and the deepest part is at the rear... 240sx crank girdle. 3 Quote Link to comment
flatcat19 Posted September 27, 2017 Report Share Posted September 27, 2017 Again...shouldn't be enough to steer someone away from a 240sx KA when it had been installed with little effort. More than one way to skin a cat. 3 Quote Link to comment
datzenmike Posted September 27, 2017 Report Share Posted September 27, 2017 That's the point. The D21 block will be less bother. 2 Quote Link to comment
