A 240SX KA24E will have more power than the truck engine, due to cam and ECU differences. KA24DE came in S13 (91-94), and S14 (95+) flavors. You can mix and match the S13 KA24DE parts between them, but there are wiring and hardware differences once you get to the S14 stuff. And wiring is different between 95, 96, and 97, then there are OBD-I '95 KAs, and OBD-II '95 KAs.

Most of latter differences won't mean much when dealing with a KA510. It's so much easier to get it all from the same car, if possible, though.

Ugh. I keep getting tripped up in the damn parts hunt.

I'm trying to throw a KA24E water pump pulley on, but noticed the pulley I found is a different type of belt from the DE style.

Anyone have any tips on what to do about this. Is there a different KA24E pulley that takes the same belt as the DE?

Anyone selling a custom pulley or tensioner????? I'm getting tired of throwing $2 a go to Pick N Pull for nothing.

This is the last damn thing I need to resolve. : /

how can you tell if you have an obd1 or obd2 95 ka24de?
I know mine came off a 95 240sx with an automatic with an HU ecm but I don't know if it is obd1 or obd2

OBD-II will have a sensor going into the top of the transmission bellhousing to sense misfires. That's an easy spot, elsewise you'll have to run down your ECU number and see what Google or JWT say about it.

AFAIK, no. You can (as others have) switch to the KA/E crank pulley as well. Then you gotta swap the pulley on the alternator as well.

What cost, custom?

is that an offer to make one?? I'm cheap, but if you could fab a water pump pulley that would work. .... hm. we'll have to talk.

I can probably slap together a tensioner fabbed out of the idler pulley I pulled off. ugh.

I'm just worn out on the parts hunt.

Cool thanks for the info! Theres a real cheap one close by that I'd LOVE to pick up but I just have no where to put it right now.
Is my dime pretty rough? yep Could it use an owner with a little more mechanical expertise? yeah probably. Does it look like every other beige sedan in the parking lot? No sir it doesnt.

I used the motor mounts from my 510, and the upper brackets from the 240sx. fits like a dream, jsut gotta bolt them to the lower holes on the lower brackets on the crossmember.

if your talking transmission, there are a few places that make them, but i custom made my own.

Does the McKinney have the single center hole for the OE 240SX mounts? If so, they'll fit. If not, they won't fit. Most of the reversed crossmembers out there still use the OE 510 rubber mounts. The OE 240SX hydro mounts are better.

I'm sure you could get DGR or TSR to do one, if you have the money. Also not difficult to make one yourself, if you have a welder. Set the engine on a stand, get the tilt correct, place the bare, reversed crossmember underneath and start building. Tis what I did for my SR swap.

Resolved my issue. and got lucky too. someone had a 24e motor sitting in a pile of rust and they let me have everything.

it works great, just gotta grind the upper bracket a bit so the belt won't rub. the hose fit over the goose neck without interfering too much, but a spacer would make it a bit nicer.

I also have some radiator hose numbers that worked for me. will edit the main comment to include them.

Wanted to first post a follow up to the penultimate disaster topic here. I've got a few more things to add to the list, maybe someday I'll actually do a complete write up.

THE CAR LIVES! FINALLY! Everything seems sound, and as I take it further and further away from my garage and trust my work more and more, I'm fairly confident in saying that, barring unforeseen disaster, the swap has been a success.

NOW....time for fine tuning.

I plan on digging into the FSM in a minute here, once Adobe behaves. ...The KA shifter seems to have a very narrow gate. I keep missing 2nd gear and slipping into 4th. I'm sure there is a certain level of comfort and getting used to in store, but I'm wondering if there is a way to control the shift gate a bit. Or if there is something to look at fixing if the gear pattern feels a bit loose and incongruent.

I plan on adjusting the clutch a bit more to make sure it's opening fully, so I'd like to make sure the shifting gets fine tuned as well.

thanks

I've never had this problem (even with a short shifter installed). I've also never heard about adjustments to the shift gate. It kind of is what it is based on the tolerances of the gear internals.
