Well from memory the SD33 isn't a Crossflow motor,

if they aren't no chance they will bolt up.

As for GQ and GU TD42 motors manifold being interchangeable there is a reason, they are the exact same motor.

TD42 exhaust manifolds will bit TB42, and TB45

SD33 and SD33T manifolds are interchangeable, but the fuel injection gear is a total pain to swap over. The injection pump is cable actuated on the SD33T and vacuum actuated on the SD33. Timing gears are also different, so swapping the injection units over is a major job (do-able, but lots of work).

Typically, you graft a turbo onto a modified SD33 manifold so you keep the vacuum actuator, butterfly and other existing control bits. You also need an oil supply line (usually from the oil pressure switch/sender) and an oil return into the sump (drilling, welding, needs to be removed from car first; sump gasket ~$60).

PM me if you are interested in a 'SD33 turbo kit' as I have set of manifolds, turbo (worn), modified sump and most of the bits that I want to get rid of. Was going to be fitted to my MQ; ended up selling that truck and getting an already turbo'ed MK.
