1978 e21 m20 turbo swap, AKA What did I get myself into
-
Ok after a ride in Mikes e28 I'm chomping at the bit to get the motor and trans together and back in the car... (after fixing the floor and all that nonsense.)
So I need a clutch and flywheel since the ETA motor I bought off mike was an autotragic.
Pelican and BAVauto want roughly 5-700 dollars for a clutchkit and flywheel so I've turned to ebay.
Before I pull the trigger I'd like some reassurance that I'm buying the right parts since I'm frankensteining parts from different years together.
Motor is out of a '84 528e which is what I've speced the clutch and flywheel for.
Trans is a midyear 85/86 GT260
Pretty sure it should all match up....
Here are the links I'm looking at
May have just found a clutch and flywheel on car-parts.com fingers crossed
I want my car back!
You may want to just buy a lightweight flywheel/ clutch setup, I spent 290 on an OE Sachs clutch for my e30. Those are "i" clutches to go with a single mass flywheel, you can tell because of the sprung hub center, clutches for a dual mass flywheel have solid centers. Connor is coming over tomorrow and we are putting in an F1 flywheel with Sachs clutch in his e36. I think it was around 500 for clutch and flywheel.

Buy an LUK kit from rockauto. LUK is a BMW OEM supplier and often uses sachs parts in their kits too but for a lower price. You'd have to research the difference between those too part numbers as I'm not sure. I'd reccomend with what John is saying, you'll want a beefier clutch for the turbo application. Any M20/M5X clutch will fit, its just a matter of your price range.
LUK Part # 03010 Idle-stage Damper (Only 1 Remaining) $138.79
LUK Part # 03013 Idle-stage Damper (Only 1 Remaining) $154.79
SACHS Part # KF29603 {#KF29601} Body code E28; Outer Diam: 9; Inner Diam: 1 1/8; TEETH:10T (Only 1 Remaining) $192.79

my experience with yards is that they do not like to ship things, so they put a high price on parts when shipping. Stupid, I know!

Did some work over the weekend, burned up my grinder stripping the inch of bondo on the ass end of the e21, then relaxed with some beer, scotch, and delicious food at Mikes sisters grad party !I see a sexy e28 in this picture...

Are the non-sprung centers just solid steel or is there a rubber damper inside, I have never worked with a dual mass clutch.
The solid center clutches go with dual mass flywheels, the sprung hub clutch goes with a solid flywheel. They serve the same purpose, the most noticeable of which is absorb vibration between power pulses at idle to prevent gear rattle in the transmission. There are some kits that sell a solid clutch and solid flywheel. I would steer clear as this is pretty sketch.

That patch behind ur gas door looks like a filler for an old fuel cell

What linkage parts? Kruse Warthan is usually dissapointing, on service and price.
I'm at my parents so I went to motorwerks BMW in Bloomington mn.
I'm going to go back on Monday when a friend of a friend is working. He is supposed to be good.
Basically the whole carrier and linkage that you have in yours John

Oh, I have been thinking about a better deal, there are floor mount shifters available like this.

We could make a custom one, it is just a plate over the shifter hole with a socket for the pivot ball. And then all that is needed is to fabricate a custom length selector rod once you know the dimension from the shifter to the transmission. Do you know for sure that the e30 parts will even work correctly in an e21? I bought a used aluminum carrier from somebody on BFC for $35 shipped so I would not but that stuff new.

Looks exactly like the linkage for my e28 as well
