Will it fit?
 

Take one of these:

And a borrowed bare chassis, and you get:

Bit tight, touching bits of the chassis on both side:

And on the back of the engine:

After a bit of adjusting to get the driveshaft lines correct, gained a bit more clearance:

Doesn't really matter as that mount will be coming off anyway, not needed anymore.
Bit more clearance around the gearbox too now, and the driveshafts are nicely in line:

Just need to get some measurements off one of the built cars, and maybe borrow a de dion so I can check clearance around that.
But its deffo a goer now, superb :D

For the uninitiated, what is that lump and what does it come out of?

Volvo T5

In all sorts of volvos, 300 bhp without any major work :)
