My 24v long term swap :) S54 I Love.

[Wanganstyle]

Was considering mating this to the Alpina m20, but will refrain for now...

[Wanganstyle]

You get all the parts i sent you? ;)

Also is that a stamped cam pulley i see? :(!

Should have arrived Thanks!

Stamped was the only stuff avail in 1987!!

But they are both in the recycle parts bin now!!

Both oil sprocket and head sprocket have been replaced by the heavier (newer) cast items.

Slightly reluctantly so but better durable and heavy than damaged.

Found some spares while hunting for dizzy delete gear/needle bearing holder item for oil drive conversion gear; I got a needle bearing holder w new bearing already installed yay.


Conversion to new style sprocket was needed for motronic 1.3 no? My euro m20 sprocket and cover had no mounting for USA style stuff so I had to use the one Dave sent me.

CAM sprocket installed (cast)

3 bolt dizzy rotor mounting + it's torx hardware (change from euro's 15mm) retained from original USA ETA engine/

dowel pin in the camshaft was removed to fit the cast cam sprocket in place of stamped.

happy new rubbers (no longer 1987!!)


I wonder if there is a harder durometer rubber bumper avail oem Motorsports, perhaps for e30 sa 327i or something



Three trash one spare.





Bitch tube was not a bitch at all, fuel rail + cluster temp sensor was a bitch, so water house was tapped for quick change cluster sender :)

Og metal end dipstick retained because plastic is yucky.





Euro non ps alt bracket and lower timing cover with place for a crank position sensor at actual tdc retained..can try its position for a cam trigger for another dme evolution later :) this is same as ETA's FYI



Locked and loaded. For install upcoming pretty soon

Beautiful build! Subscribed

[nando]

yeah, I told him about that too. hell, if you want, I've got a cast one laying around.. I don't have an intermediate shaft pulley though.

My friend was the one who did the group buy on the ATI. As far as I know all of them have been deliverd and most installed at this point. Those guys are a pain to deal with (ATI) also each unit has to be machined to a motor. The diameter of the snout has to measured to .001" i believe.

[328ijunkie]

Just so you know. You rock my face.

[e30serg]

Ha! I used the same shop for my s52 engine work. Good guy. Has a high-mileage '02, I think.

history

[nando]

how about the ocassional track day (2-3 a year, tops)? I guess just adding a cooling duct would be sufficient. a 22lb E36 M3 flywheel sounds more appealing than the stock 28lb version.

[Jason89i]

you don't feel that the single mass contributed to this at all? I have never ran a single mass with S54 engine, my s54 killed one dual mass fly though.

my last stock dampener was not cooled well and saw some crazy stress, my e36m was street car though; usually stressed @ high speed with reasonable airflow.

balancer failure --> rod bearing damage makes sense! any photos of the bearings walking? did it damage the crankshaft?

i have never heard of a street car loosing a harmonic balancer..... but a lot of race cars do. yes, you can stress a street motor, but a street car will NEVER see the prolonged stress / heat that a track car will.

the motor i had was an '01 w/ ~30k miles.......WITHOUT the bearings being replaced. after pulling the pan, i found the rods had some movement along the crank axis. i have not taken the shells out, but i am expecting to see some copper when i do.

cheers, jason

[nando]

flywheel is not the issue. heat is. apparently, you need to duct the balancer. I had my radiator pointed directly at it on a hot track day.

good to know!
