I have a 1990 300ce 24 valve with CIS injection. I plan on swapping in a 95-97 c36 engine. I know that the 3.6 has HFM injection which creates a bit more work for the swap. I plan on using a 3.2l or 3.6l ecu with a w124 e320 wiring harness. Is there anything else I would need to swap out to make it run like a champ? ...or even run at all

I also plan on putting in a 717.404 16v getrag transmission.
is there any electronic modifications needed for this?

also what differential would you recommend for my set up?

Any information, tips or opinions you have about this swap would be greatly appreciated.

Hi,

wiring harness from 320 and 3.6 are the same.
If you use a 3.2 ecu you should bring it to a tuner for flashing a 3.6 programs on it.

It depens on the age of the wiring harness.. if you are using a very old one,
the knock sensors maybe must be changed... but there should be no problems!

you should use an ecu from car with 4-spd gearbox.
if you want to use the ecu from car with 722.6 gearbox,
it could be a problem because of the missing ASR system.

If you want to go for manual:
I would recommend 717.450 tranny from 320E and differential... depends on your driving style.
I would take a 2.65. It is nearly that short like a E36 wagon with 4-spd auto and 3.06 but you will have an overdrive gear...


The coolest swap would be, if you take engine with 722.6 tranny and try to use it with original ecu/ tcu!
The 722.6 is very nice, especially with M104 3.6 it should be a lot of fun!


Here is a gear ratio/ tranny comparison table I made once for me to find a decision...



regards Rod

Rod,

Thanks for all the input I really appreciate it.

I plan on trying to find a pretty decent wiring harness because I have heard of people having issues with the harness not being insulated that well and it failing over time so I am going to be looking out for that but was not aware of the knock sensor issue.

I really want to get a manual tranny in my car because I just think it would make it perfect especially being behind a 3.6 amg. I like to drive agressivley and use cars to their full potential, my driving record and insurance rates reflect that mentality also lol

I noticed that you are from Germany, however me being in the US I don't know if any of the 320's here got the 717.450 so it would be a really hard transmission to get. I do know that the 300e came over here in limited supply equipped with a 5 speed manual but those are really rare and would probable cost an arm and a leg to get a decent one. That is why I mentioned the 717.404, which is a bit more available but still really hard to get.

I have the 300e 24 valve diff already in my car, I don't know how that will hold up to the getrag and c36 combo performance wise though?

280hp wont break your diff... or really much else... unless you just rag the poor thing into the ground. If so even 160hp would probably break it.

The .404 trans requires a different front drive shaft as well as modifying the E320 auto ecu and/or wiring harness to function properly with the rev limiter and cruse control. The .404 trans will also require the single mass flywheel, not the dual. Those are quite very rare for teh 6cyl. They are different, so take note, and only the pre 88 2.6 and 300e manuals came with them.

You could us a 717.432 with the dual mass out of a 2.6 or any of the other 6cyl M103/M104 transmissions. They will have the overdrive but no dogleg.

As a side note... .when your .980 comes out... let me know.

Any info on how strong these boxes are compared to a 16v box, how much TQ/HP can they handle ?

Great info, thanks. It is really going to depend on which transmission I can actually get my hands on at the time. As far as the .980 goes I plan on putting it in a 190e shell and fabricating a centrifugal supercharger system for it with a dogleg tranny. But if those plans go to hell I will definitely let you know.

And the question Joreto asked would be good to know as well if anyone has the answer, or at least a ballpark estimate

u can expect them to live with some 280 lbft safe.

How about the 16v getrag box?

Can anything be done to make them stronger or handle more power?

I've ripped my .432 apart personally to rebuild it. I do not think it would hold up like the dogleg can. IIRC there are a few on here that are around 500hp, but past that it's either auto's or a different trans (I'm using an R154). This is a little less than can be run on the 16v motors as they produce less torque than the big 6's. A 124 chassis (heavier than a 201) with sticky tires and an M103/4 will toast the dogleg if there's any kind of forced induction going on.

As far as the .432 goes, 1st gear, the transfer off the input, and 5th are HUGE and I don't think would be issues, but 2nd and 3rd are these cute little things and imo, if could probably run 350tq through them, 400tq if you're nice on it. Past that I'd think you'd ring the teeth right off the layshaft.

I am not familiar with the .432, is that a manual or auto?

And, what does it come off of?

Thanks.

MAG58, I don't think that the w124 is that much heavier than the w201 (at least the manual ones). I recently measured my w201 (16v based) with the m103 3.0-12v turbo motor and it was 1300kg . Browsing the net I see that the early 300E/300CE with manual transmission weight about 1340kg - 1390kg (if these numbers are correct of course ) , so a 16v box in such a w124 should holdup as good as in a w201

Well i guess the only way to test is to get a getrag behind the 3.6 and see if it blows up or not, if all else fails i will just throw my stock tranny back in.

I plan on doing a centrifugal supercharger on the 3.6 as well, not boosting over 8psi though. It will be intercooled too.

I'm always interested in this number you got... what year is your w201 and with what options is it equipped (I.e. electric seats/windows/etc.)

FWIW, the 717.432 and 717.430 came out of the dual mass and single mass (respectively) 5 speed manual 6 cyl 300E, 260E, and 190E 2.6's.

Thanks for the the info on the .432 tranny. That might not be that hard to find in the U.S.

joreto, the W124 has better rear grip thou not much heavier than the W201. Hell a W124 has more rear grip than a W202 as well.
