N/A D24 loses power nearing max revs, brown black grey smoke

[245d6]

Alright i'll check again, just printed the workshop manual

Last time i did the timing belt I replaced the crank bolt, is it actually necessary to do so? I remember I bought one of the last ones in stock. The manual also says to replace the flywheel bolts.. Would like to get everything done and back in the car tomorrow rather than waiting for expensive bolts.
