is it worth the time and money to modify a 1.2 16 valve engine? what kind of power could be gained, and would it be worth it?

Hmmm not really mate, i like the tinkering of engines, but it really not worth it, you will pay alot of money for less than impressive gains. i wanted to mod mine but im just saving for a new motor now and mod that :D

its not a main stream tuning engines so theres not really many mods for it

try induction kit
decat and stainless steal exhaust
maybe a 4 branch manifold
fse boost valve to regulate fuel

other then that im lost

you can't really do that much with them mechanically i.e. camshafts, porting etc. because the head and the block start fighting each other (in tuning terms) summarised, this means that anything you do to the head will make it want to spin-up faster, but the long-stroke nature of the block will fight against it so anything you do will become self-defeating and produce only very small power gains. If you were determined enough with the block, lighter pistons, race-spec con-rods and a lighter flywheel would be the way to go before tuning the head to suit, but again i wouldn't expect much out of it in terms of mid-range torque, it'll more than likely end up with top-end power and nothing else below and still not much improvement over standard.

So eventually you'll damage the engine in the long run?

of course, its not designed for more power, its designed to withstand the pressure / power that the engine has as standard!

still too heavy regardless, there is a limit when fiitting bigger engines, a 20LET will handle better and would be quicker :thumbs_up:

Try This

I was going to buy a 1.2L 16V corsa until I realised it was a bad engine for tuning. Turns out the 1.4L 16V is only £30 a year more on my insurance and is a much better engine for tuning.

Shouldn't cost to much more to run on petrol and your still in the lower tax band.

I'm hoping to get one about July now ;)

The only real decent engines to tune from a corsa is the 1.6 dont bother with the X14Xe

The x14xe's are good for what they are, but if you can afford it then the next natural step is the x16xe, then the big block engines after that.
