How mu ch to offer for a Dogleg???

[Kingb]

My boss has had a dogleg that he has been saving for a future project car and he just bought a new 335i. I convinced him to get let me get it off him. I just have to guve him an offer. The story

It came from a euro 323i. The people installed it and thought 2nd was 1st and that the motor they installed with it was messed so they pulled it and put a different motor and trans in it. Then realized what they had and my boss got it off them. Now this was back in the 90's and it has been in his basement since. He says it needs a shorter drive shaft but he has never installed it himself. I will see it for sure tomorrow.
What do I offer him?

[asubimmer]

$100 ;)

[Kingb]

Thats what I was thinking. I am going to see it tomorrow So I can see the model number. Is this the one that needs the big guibo?

[rThor432]

Nah the one that came from the Euro 323i has a little guibo and supposedly doesnt handle much power. That said, I've had them in two cars and love that gearbox. I paid $300 for one and the other came in my 323i. They are worth around $1000-- at least I've had a few offers in that neighborhood for the spare I've got now. In this economy I see nothing wrong with you offering him a healthy $200 tops for it... in the true nature of R3v...

[MeesterPieter]

you do need to realise you need to replace much more then just the gearbox

gearbox suspension, drive shaft, diff, rear axle drive parts etc

also fits 323i and early (pre 86) 320i only, fits other m20's but with more problems

nevertheless, always buy one when you can get it cheap, if you dont want it, i'm interested :P

So what would I have to do to put this dogleg in my 90 325i. he had told me that the drivelines are different. I also have a 3.73 LSD that I just put in. I really want to put this in.

[rThor432]

The difference in the driveline shouldnt matter because of the slip-joint. I have a friend who is running a dogleg driveshaft in his standard 260 car because he blew up a driveshaft and the dogleg happened to be sitting around. The difference is less than an inch iirc. I've had both shafts next to each other recently..

You will need the specific shift console (which is sheet metal) and the other linkage parts, as they are a different length. Those should be availible at the dealership cheap. The crossmember/support is different (only uses one mount). I believe the slave and t/o bearing are unique.

I messed around with converting the unit to an aluminum console a while back. The sheet metal console works fine in a late car, so I stopped bothering with it, but it would work with a little bit of welding if you prefer that route (a lot of people love the aluminum console, not too sure why..).

The diff and rear axles dont make a difference. The only thing is that it is ideal to get a numerically lower gear because of the 1:1 5th. My 323i's have had 3.23 and 3.25 gears from the factory.

[Kingb]

So first I need to find the part number so that I can look it up on realoem. then I have to find a slave and a sheet metal console. I can make a tranny mount. I have welders at work.

[Kingb]

Ok so this guys has also done his research and says that these things are worth as much as 3 grand when fully rebuilt. He is in no hurry to sell it but would let it go for about $750. It has a guibo, slave cylinder sheet metal console with new bushing, including shifter with a euro M3 knob and the fork with an old TO bearing.

Here is the number off it 242.0.0291.01

[guibo09]

how much easier is the conversion with the dogleg that came on euro M3?

[NC325iC]

if youre gonna put it on an m20 it'll be alot harder
different bell housings i believe, please correct me if im wrong

Thor you said they cant handle much power, what kind of range would you estimate

I am guessing you are tlaking about the M3 dogleg. I looked it up on realoem and it says that the euro M3 came with the 265 but when I cross referenced the part number it says M3, 318i, 325e/i and so forth. I dont think thats right. But the one I am talking about came off a M20B23

[rThor432]

Yes, the bellhousings are different. You have to track down the bellhousing from an 82-83 528e.

I personally wouldnt be afraid of 220-230 hp. But that is me, I shift like grandma. There would be a risk there. I'd say that 200 hp would be plenty safe. Standard the M20B23 did ~150 hp and 150 lb/ft. I think you'd be safe running it up 25% anyway. I know that Pete McHenry had one behind a solid built 2.9l M50 and he blew it up on a road trip. No telling how he was driving, but he lost 5th. That would mean that he loaded it up pretty good, but I'm not sure what exactly it takes to blow one up.

That said, I wouldnt put it behind a DOHC motor, I think they have too much torque. I do think it would be nice behind a 2.0l M42 though..

I've had both of them side by side and the case is much smaller on the 245 M20 version. Spacing between the main- and countershafts is also a lot smaller, so the gears are a lot smaller. That's where the power handling issue comes into play.

[Kingb]

rThor432 or anyone. What throwout bearing do I use with the dogleg? Will the normal 260 work. My clutch is brand new. Or do I need the one for that trans?

I have one of his right now but it's a 3 pc for an S14.
