So you've taken the BIG plunge, as you already are aware, you are going to have a difficult time when re-assembly with keeping the 90 degree setting, without being able to lock the crank in position through the flywheel.
As you've gone so far now, for absolute piece of mind remove your engine/gearbox, re-fit the oem flywheel (temporary) re-assemble engine, remove oem flywheel, and mark and machine drill your os giken flywheel, then have the balance of your os giken flywheel checked and adjusted as necessary.
Alternatively when you've re-fit the cylinder head, take very very careful and precise dial gauge measurements through the spark plug hole, keeping a very careful eye as you re-fit the timing chain, and just a note, if your not sure or don't know, you MUST fit new camshaft sprocket bolts, with a tightening torque of;
Vanos sprocket bolt: 20nm + a torque angle of 180 degree.
Exhaust sprocket bolt: 20nm + a torque angle of 90 degree.
If you need anymore information then let me know, and good luck.

This should be very interesting.

1. Very adventurous of you to break new ground on N14 internal work.
2. Research suggests the stock ECU does not like cam replacements, hopefully you will not be stuck in limp mode, requiring an after market ECU?
3. Exactly as K has queried, what was the assignable cause of the overheating?
4. Congrats on the track car! -

We are crossing our fingers for you.
It will be great to see it out on the track when you have it all done. -

Very cool
First time seen the internals of an R56. Like an earlier post, isn't the ECU the hold up in doing mods on the R56?
