Default B230ft Swap

Hello Everyone! I recently purchased a non-op 1994 940 turbo wagon. I've just gotten done taking out the engine and putting it on a mount to work on some modifications before I put it in to my 1989 5 speed 240DL wagon. I need to get rid of the 940 soon to free up space in the driveway and I want to make sure I have everything I need before I get it towed to the junk yard. This is my first time doing a swap like this so I'm not incredibly informed on what the entire process is. So far I've kept the engine with all the accessories and intake on it and left the transmission in the car (it was no good, and I plan on using my M47 5 speed). Other than that I've kept the inter cooler, radiator, flywheel, and torque converter. I have the downpipe taken out as well and can keep that if necessary. Other than that I'm wondering what else I'll need to take off to do this swap. The only thing I can think of is the wiring harness, but I'm not sure If i need it or if I can use the one from my 240. If theres anything I'm missing, or any other parts that would be useful to have I'd appreciate the input! Thanks. (Also if anyone wants a 940 wagon shell in southern California and has the means to tow it I have one!)

You have a wiring harness you can use in the 240. I wouldn't leave the 940 a rolling shell because the rear axle has a G80 that you can use for your 240.

I would take at least some of the wiring and connectors from the parts car because you may need some to splice in a connection or two and it's nice to have the same color codes and connectors to work with.

You'll want the turbo LH2.4 ECU and EZK boxes, plus the injector resistor pack with wiring harness.

Re-use your 240 engine harness, but keep the MAF connector and extra wire from the 940 so that you can relocate the MAF.

You'll need some sort of air filter for the 240 - the 940 Turbo air filter box doesn't fit, but can be hacked, or a gutted B21FT k-jet box, or a diesel box, or an aftermarket cone filter. Keep the turbo&intercooler air hoses too - I'm not sure if they'll fit perfectly but some should be reusable.

I'd pull all the 940 relays too just so that you have spares.

Is the 245 lh2.2 or 2.4? You're going to need a different flywheel regardless to use the M47. Definitely hey the ignition and fuel computers.

You will have to get the flat flywheel machined for 60-2 triggering, or a dished flywheel and clutch PP setup, but that won't hold power for long (which could be a good thing for the M46)

I have done a similar swap with a 92 740T into a 90 245. I was able to use everything from the 740, larger radiator, intercooler and plumbing. I link you to my build I had a lot of questions answered for me in that post.

any idea if i will need to modify a flywheel for bolting up an m47? I have an m47 and flywheel that i pulled from a junkyard car a few years back. The only problem is i didn't check what type of ignition system that car had.

Whats the year of the car that you pulled the flywheel from?

Does the flywheel have 60-2 teeth on the edge? That's what you need for lh2.4
