TCU TurboLamik

Hello every1!
Have some questions in case of my future swap in e60 530d lci
1.Who have experience on installing 8hp75z from G-series?
2. Is b57 flywheel compatible to n57? In bmw ETK their numbers differ.
3. i’m very confused in gearbox length. Maybe some one share how long 8hp70 from F-serie?
Because my current 6hp28 5mm shorter in length compared to 8hp75z G11. In this case with adapter plate i got 20mm more length at all. Then need some custom modificatins for rear mount. Of course oil tubes need to be longer too.

Hope to hear any suggestions and opinions

Hello.
1.both 8hp70 and 8hp75 work with the TCU but you have to bear in mind that the control program for it is different.

2. For the M57 you need a flywheel from the N57 as well as a gearbox.

3. I think 8hp75 is longer. It is easier to mount the 8HP70. Oil tubes are attached to the engine foot. You can detach the handle and move them easily. You can buy special oil adapters from TurboLamik and screw on oil tubes from 6HP

Thanks for answering, Jar.
1. So, TCU can be used and work with 8hp75 from RWD G-serie B57?
2. You mean that B57 flywheel didnt fit on M57? Tomorrow i will try to compare n57 and b57 flywheels face to face.
3. Oil lines in whole case is easiest problem to solve ) there was no problem to change their length in any way.
I’m already buyed oil adapters, but they are for 8hp70, but 8hp75 holes a bit bigger (18,5mm), and here is too not a problem to make other adapters.
Hope you confirm possibility for successful working with 8hp75 rwd from B57

1. ZF 8hp75 is a gearbox model and it doesn't matter what engine it comes from. only the mounting bell is different. So it will work
2. Flywhell from n57 and b57 is similar or the same, So you can use both.

Thank you again for answering
Yes, today I compared both flywheels, they are completely same. Only difference in TC mounting holes (different location relative to the mounting holes to the crankshaft), and hole for fixing crankshaft in TDC service mode.
And B57 flywheel seems to be stronger


Hmm, about different mouting bell did not thinked before...I assumed they were the same need to check this moment and place adapter plate to gerabox.
I know that rear mount not same as 8hp70, i attach f01 n57 braket and holes a bit different in horizontal position, need drilling.
