Thanks Braymond. I got pissed and cut off about 1/2 inch off the bracket. You are right. Not as easy as the sellers make out. True for this and other aftermarket mods as well.

I left the rear support brace as I did not have any problem fitting it. The front simply does not fit with the aluminum adapter plate installed.

Looks like the whole thickness of that blue adapter plate is extra space between the manifold and the M52 'plate'.

In 2012 I used an Alpina357 (Guy from UK) converted M50 manifold, that has the M52 plate as good as directly fitted to the manifold.

This made it PnP without any issues.

That sounds great. Lowering everything with the adapter plate causes a lot of fitment issues. I worked around them but I wished the TMS instructions took into account all the messing around needed to get the fitment right.
Does the person you mention make these for sale?

The old forum is dead. Don’t know if he still does it. I guess it’s not really a business anymore.

Still need to remove mine, as I want it make to stock. Since I have the M3 now.

I also bought bigger tb’s kit from him (main and asc+t).

Default Re: M50 manifold installation question (yet another)

Hey guys... fwiw... I just used my front bracket and omitted the back bracket.

as for fitment issues... i have had all the above issues as stated, needing to bend the larger hard coolant line as well as the smaller coolant line that feeds the TB. I also found when i went to put the TB back on it was all shifted down so i had to bent the smaller hard line back up. I also found that the OEM bracket actually is touching the hard coolant line! when the manifold is seated property and down all the way.... is that normal? is there concern for long term reliability issues.

another issue i found is the ICV plug... it is basically touching the hot lead to the starter... no wires are exposed but that still doesn't seem ideal.... same for you guys? doesn't seem like i can get that terminal wire to bend any more.

Lastly i found that the CCV hose return to the dip stick needs to be shortened as the OEM hose is too long and bends akwardly which if figured would fight gravity on the return tot he oil pan. Also the CCV is relocated down and is VERY close to the motor mount bracket that connects to the block... is this NORMAL too and are there any long term issues?

Here are some pictures.. i stripped and painted my turner adapter to black so its more discreet for SMOG purposes. Any feed back on my work is invited

thanks

I cut the bottom off the bracket so it would not press hard against the metal coolant line. I did not have the issue with the IVC plug. I re-routed it so there is less stress on the wire. I also installed a new starter and the new starters are smaller in size than the original (still a Bosch unit).

Do you feel like cutting the bracket was totally necessary?

Can you explain how you re-routed it? did you cut the zip tie it was bundled too and then run it around the back of the starter cable?

Also... do you see any issues with the CCV being so close to the motor mount bracket?

thanks!
