Default 83 242 b230ft/LH2.4 swap, A few questions.

I am about to embark on a 94 b230ft lh2.4 swap into my 83 242 dl, I have the complete 94 940 and there are a couple 240's at local junkyards for other parts.
What distributor will I need.
Will my b23f work or will I need one from a lh2.4 240?
What rear end/diff will I need.
will the 940 rear work? Or what year 240 will work.
Clutch suggestions?
I have purchased a modified flat flywheel for lh 2.4 so need 8"

I got a complete 2.4 engine/interior harness from a 93 240
Cluster from a 89 240, tach from 86
Computers from the 940

Please let me know if you have any advice or things I need to watch out for with the project, Thanks!

This thread will almost certainly lead to some form of "search bashing."

It is a topic that is at this point common knowledge to those on the forum frequently.

The search function here is testy at best, I suggest starting here:

site:forums.turbobricks.com LH 24 swap


Insert that into google (or click it) and read every thread that comes up, you will have all the information you need to swap your car. All of your questions have been answered on the board. Happy Hunting!

Right, I can probably figure most of this out on my own.
I figure I should probably grab a 2.4 distributor from a 240
I've been reading about the abs front hub and deleting the idle air control valve to bypass the rear diff speedo

If you have things apart and have some $ in your budget for it, it may be worth it to do a clutch upgrade so you don’t have to worry about it later. One option is to have your flywheel drilled for a 228mm Saab Viggen pressure plate (dowel locations need to be moved) and use a 228mm Volvo disc (assuming you are running a M4x trans).

Thanks for the info!
I ordered and received my flat 2.4 modified flywheel from STS machining and it curiously came with 3 dowel pins in a bag, and after reading some about this 228mm upgrade I am wondering if the flywheel is already drilled for this mod.

Based on the image on the STS website, the dowel pins are in the stock location (next to the threaded holes). The Saab Viggen pressure plate uses the same threaded holes, but needs the dowel pins moved between the threaded holes.

My flywheel after having the dowel locations moved:
Blue = threaded holes
Red = stock dowel location
Green = Viggen pp dowel location

Some stock flywheels have the holes in the middle/green location. Stock flat 215mm PP will work with either dowel pin location.
Dowel diameters are also different.

Alright, so i should be able to order the Sabb Viggen pressure plate (from 99-02?) bolt it to my flywheel and drill in the green locations for dowel pins?
And what Volvo clutch disk did you use?

Yes, the 99-02 Viggen pp (Sachs 3082302731) will work as I described above. I had a machine shop resurface the flywheel and change the dowel location at the same time. A few other members are also using this setup. It is a stronger pressure plate that works well to support moderate power upgrades.

Re: disc...
per Rock Auto, the B230FT manual trans clutches are 9" (228mm). (ex: 1987 740T, manual)
So you can either get a clutch kit and just use the disc or buy the Volvo disc (p/n 6814584)
https://www.eeuroparts.com/Parts/132...Disc-6814584G/

FYI, when using the Viggen pp, you will need to space the pressure plate out from the flywheel ~1-1.5mm using washers. I used M8 washers from Fastenal, but if I were to do it again I would use these ARP washers that have a tighter fit on an M8 bolt.

All sounds pretty straight forward. I'll order all this up.
Did you use the 740 throw out bearing?

The OE throwout bearing will be fine. Are you running a cable or hydraulic clutch? (they use different throwout bearings)

Ok, then just use the TOB specified for the cable clutch.

IMO it's a fun puzzle to fit all the different pieces from different year 240s together.
