Well Makkiver is running over 300hp, +400Nm (B23, Holset HX40, ported 531 etc...

With "well enough" I meant that it will hold much more power than stock gearbox and diff can handle.
Half Time also had the same setup in his 360 and he went through couple gearboxes and diffs.. so there was some power involved.

Engine and the car are for sale, if I just had enough money..
Flat flywheel from a bigger Volvo (74-84 and pre 87 NA used flat flywheels, there are also "dished" ones which are quite same as the 360 stock and also much more heavier dual mass flywheels used in bigger Volvos but dual mass wont fit in without machining and there's no point putting a heavier one in), 228mm VW/Opel disc and 240 or 740 turbo pressure plate should be quite good combination.
When putting in a 228mm sintered VW/Opel disc, clutch gap should be adjusted correctly so it will work, if it's not shimmed it will slip. Makkiver used normal washers to shim his clutch, basically it's " new stock disc thickness minus the thickness of the sintered disc" and that's the number how much you need to shim.
Though the stock 360 flywheel should work too, flat one is just a bit lighter. Dished one weights 13.7kg as the flat one weights only 9.6kg. So it's not necessary to change but it gives a bit more faster reving.
