ok...Ive learned ALOT..but who is using the 260?

[JRKOUPE]

So who has been using the M20 getrag 260 and oe drivershaft w/ their M/S 50 swaps??......

I plan on using Doug's custom tranny bracket

My set up will be mainly track driven so Im concerned about robustness. My concern is about all the engine/tranny holes NOT lining up. Some have run the set up w/ the mis aligned holes unattached and have reported no issues.

What have you done?..

any issues?
do you track car?

Id like to save the cash by using the 260 set up but dont want to end up having headaches and repair bills down the road. Im just thinking this set up may not be good for mainly track work.





tia!!!

Im using my 260, so far with dougs bracket every thing is working great. It lined up perfict. NOT running yet though, but yes you will have issues with the holes i only have 4 bolts in there as of yet.
The two main top ones that are pretty big fuckin bolts, and also there are 2 of the bigger torks head bolts in there.

As for if you plan to track your car, not trying to say you wouldnt already know this. I would find a way to get some more bolts in there.

I was thinking of maybe finding some of the ones that kinda line up. Then just drilling a hole and making it so i could get a bolt in there. Locking them to gether with a Nut and washer on the other side just for some added strength.

Any one say NAY or have a better idea.

260

......so 4 bolts will work.



.....how many are there in total?.....

geez..it seems sketchy. Any pics?....


and thanks.

[MR 325]

I am using it, no issues. There's 4 main bolts and the 2 starter bolts. Perfectly fine.

I don't think you have to worry about it holding up. My turbo car made more power than this one and it was just fine.

Well, that's because you have a good instinct.


If it really didn't matter, don't you think BMW would have saved themselves millions of dollars by not using those additional bolts? Will it work with only four bolts? Sure, it'll work. Will it be 100% as rigid and stiff as it would be if all of the bolts were in? No.

What about dowel pins?

[B3M2W5]

IDK if dowle pins would work or not im assuming so.
I know it wouldnt be as ridged but it will work. I am porbly going to throw one more on the bottom but then again i only plan on light track if that other wise just daily driven.

For his app. I would suggest trying to get some more in there if your going heavy track. Espesialy if you are running an M/// motor with more power. I am only running an M50 so iam not pushing any where near what you would with a tracked M/// motor

The only bolts that don't work are the inspection plate bolts.

You can keep yourself convinced it's not safe to run without those and I will continue to disagree.

Instinct? maybe... or just common sense. Im also not a kid just trying to throw more hp into a $2k car. I want a reliable worthy track ride.....i have alot of money in her....and my life as well. But on the other hand.....BMW made a poor shift linkage/ poor motor mounts etc. My point is many of BMW's decisions are money based not performance based. And many designs are based out of fear of liability....BUT...... I get your point for sure! Im just wondering what everyones experience has been.

Where did I say it isn't safe? You should read and understand what I have clearly typed out before responding.

I chose to use the proper tranny for the job, not a half assed approach so I don't have much experience with using the improper number of bolts to hold my engine to the tranny. Forgive my lack of knowledge on the subject, I was merely voicing some common sense.

Even without an inspection plate, you are allowing debris and water to enter the bell housing much more easily than it could otherwise.

And yes, dowel pins are there for a reason too. That reason is to locate the parts since a bolt on an oversize hole is not designed to do that.

I am gathering parts for an m52 swap and I am planning on using the 260. I have one of Doug's tranny mounts on order. Are you saying that I can use my stock 325i driveshaft with this setup?

If you're so knowledgeable you'd know that the inspection plate is part of the oil pan when using the E34 piece. Therefor, it's still sealed up just fine.

well..... umm,..yes. Thats the whole point of the Doug brace/260 set up. What were you going to use?

..your responses make me think its no biggie at all. It would help for me to see it in person.........or photo.



Any one?.....
