welcome! you should drop by the motorsport section, there are plenty of people with dedicated track and rally cars there
Bloody oath it would be! If you have a winch to hold the motor up you have a winch to pull the motor out!
Anyway, behind the flywheel there are are 4x M6 bolts from the rear main to the sump. Unless you are feeling really keen and want to drill access holes for a 1/4" 10mm socket, the flywheel has to come off. And to get that off the gearbox has to come out.
which way does the rod on the clutch slave cylinder face? If it points forward you have a pull type clutch and you have to release the fork from the trust bearing before you can pull the box off. If the clutch slave faces rear you have push type and the gearbox should slide straight off.
You will probably need to remove the tailshaft and attessa line to move the gearbox far enough to get at the flywheel. Don't forget to bleed attessa when you put it all back together.
For next time, removing the motor is a much smaller job than what you are doing now.....disconnect gear box, remove intake above the turbs, undo front pipes, undo wiring on the intake side and top of motor, pull DSF driveshaft out, remove front intermediate shaft, radiator hoses, oil cooler lines if applicable. Fair bit less work than doing the whole subframe
