Which V6 Donor

[ProtoTipo]

If you're not chasing big power then the 2.5 is a good choice, plenty of go, all the right noises and stacks of them available.

Don't they have the second lightest stock flywheel too John? 'First being the GTA?

Think that's correct. I always thought a 2.5 with 3.0 liners and pistons would be interesting, well over square 2.8

Hi Tom,
i am not sure if an 24V will fit in an Allora?

i have the 12V in my Allora and to the bulkhead are only 2 cm
and also to the rear frame are only 2 cm space! look pic:
please take the measurements from an 12V and 24V engine.
And it's necessary to but it lower in the engine bay!
otherwise the rear clam did not close! it lies on the inlet manifold!

'Good point Enzo. The Allora rear frame is (somehow??) lower than a Hawk.
The 2.5 alternator will be at the rear, so alternator clearance at the front won't be a problem.
Clearance for the 4 cam head might be though, with the vertical bulkhead.

Worst case, tilt the engine back a touch, lose the 156 plenum and fit some itb's,gsxr 600?

Tom's rear deck/clam is cut out below the rear louvres too Enzo. So that shouldn't be a problem.
I think that's the case?

someone have an picture from the engine holder in a hawk?
here is a pic from a Allora,
so you can see what i mean!

The engine steady bar on a 156 v6 is behind the rear bank cam pulleys, not above, don't think height would be an issue.

Yes my rear deck is cut out,much cooler engine bay.

Thanks for all the information. 156 2.5 12 valve will probably be the way I go. Dont need loads of power.

Tom.
