As long as the 16v is effectively the same engine as the 8v (okay, twice the valves - but you know what I mean ), then I can't see any major issues with the swap (as long as you swap complete engines, rather than trying to convert one into the other). Positioning of sensors may differ, but that's all I can imagine.

I read quite a few car mags, and believe me, if they can get fwd Vauxhall engines to run rwd in Fords, and fit sierra sapphire cosworth engines & 4wd into a Ka, then this type of swap sounds fairly straightforward by comparison.

If your existing engine is in good shape, and you fancy a bit of extra top-end power - you could always try a shot of the old laughing gas .

Remember, 8v engines have more torque (and horsepower) than 16v engines in the lower rpm band - its only when you get above say 3,000 rpm then the multivalve has the edge - so its not really a case of 'free' power, there is a trade-off.


This job should never be complete - the day I think I've done it all, is the day I resign.

Just dropping a 1.2 engine in should be fine though, remember that your existing ecu does control other parts of the car (locking, alarms etc etc) and thats why you should keep the same one or lots of programming and stuff will need doing.
You should be fine though...

hi thinking of doing the same thing will the 1600 fit on the 1200 gearbox thanx ...

Interesting thread. I've toyed with the idea of replacing my 1.4 16V as I've never been happy with the drive compared to my old 1.2 8V. Reading what VelSatisfied said about torque it might explain why. I don't think I can justify the cost though.

Re: replacement engine

I would also ensure that you get a decent warranty with the replacement engine, in case of sticking valves for example.

My 1.4 16V Clio suffered a complete engine collapse through overheating - water pump broke, cambelt snapped, big damage etc - and I had an identical spec'd engine fitted that had only done 55k miles, as opposed to 108k that broke.

Unfortunately it seems the 'new' engine suffered from misfiring, probably due to sticking valves and despite using fuel additives and fuel flushes, as well as initially replacing throttle position sensor & coil pack in an attempt to solve it, its still not right and out of warranty.

Basically, common sense, make sure your replacement engine is working absolutely fine and ensure your warranty is good.
