V6 interchangeable with 4cyl?

[Pugly]

I'm just wondering if the 406 V6 engine will fit into a standard D8 car that had a 4cylinder engine?
I have a 96 406 ST with a blown engine and there's a V6 engine for sale. My car has the 5 speed manual box.
Any chance?
Thanks in advance.

Well you probably could do it, but you'd also need the ecu, engine loom and ancilliaries.

To expand... it has to be an ES9J4 (not 210bhp ES9J4S) and you probably want one from a D8 due to the ECU and different wiring. You'll want:

ECU
Relay box
Engine wiring harness
Air intake pipework
Air filter box
Engine mounts
Gearbox
Complete exhaust system
Driveshafts (probably)
Wheel hubs (probably)
Throttle cable
Pedal box
Clutch hydraulic system
Radiator and water pipes

The ECU may also barf about the power steering rack, as the V6 models had variable PAS.

Do you think the engine would fit onto the gearbox then? I can see it would need the exhaust manifold and the ECU but maybe the loom should work? No? Stupid idea?

BTW I ride a Guzzi. Cheers.

O right, thanks, I see it's not going to happen. Many thanks for your expertise.
Cheers.
