Engine tilting
Engine tilting
(OP)
I am in the process of making an attribute mockup of a individually constructed vehicle. I will be using a Mitsubishi 6G75 V6 engine and 5 spd manual gearbox. To get the drive output to the height I require I need to raise it 45mm. The simplest means is to tilt the engine/gearbox 12 degrees forwards. Obviously I will need to check the sump pickup and gearbox oil levels, but does anyone foresee any other problems?

RE: Engine tilting
You are correct, in a transverse engine I don't believe this will be an issue.
Merry Christmas.

The second chassis will be race-only (or I envisage it so) and I will rotate the gearbox, which will allow for a dry sump and a 50mm lower engine (lots of work though).

I'm not quite sure how you are fitting this engine,do you mean you are changing from east west fwd to north south rwd?
If this is the case one prob you might encounter is oil frothing if crank and rods contact the oil,another option might be to source a sump and pick up from a rear wheel drive model eg ute or 4WD as it would be baffled in the right direction.
Happy New Year to all!

In practice, none of the worries of oil buildup in the valve cover are a problem except when you remove the cover. No oil pickup problems (I still use an accumulator, however).
23 degrees? Hmmmm...I think I could make it function. At least you don't have the gearbox and engine sump combined.

Plan on tinkering with the suspension bushing specs and toe curves a bit. The same effects that give you understeering tendencies when applied to the front suspension typically become oversteer when you move that same hardware/geometry to the back end. I think the rather low "production" SHOgun (Taurus SHO powertrain mid-mounted in the Festiva chassis) went through this sort of teething pain.
