Its discussed the 1.2 16v Corsa engine used in B and C, is largely untuneable. Is this because its a poor or economy based engine or a general lack of bits or just not worth modding at its capacity.
How closely related is it to the 1.4 and 1.6 XE regarded by Tuners like Velos as highly tuneable. Or is not an XE Series and not related.
SO far on a 1.2 Sxi Corsa C, a drilled airbox and K&n panel filter have netted a 7 bhp gain at wheels, std car making 55. Modded 62. This was using Optimax petrol. If there is a way to uplaod dyno prinouts, then I can.

for a start
1.2 16v corsa B - 65bhp std
1.2 16v corsa C - 75bhp std
not worth throwing money in a 1.2 IMO
these engines are not related to the 1.4 and the 1.6 engines as these were developed by lotus and the 1.2 wasnt cant remember exact details

The 1.2 16v engine is totally different to the 1.4 and 1.6 16v engines.
I would say one of the problems with the 1.2 apart from the size of the engine, is to do with the inlet manifold design.

The Corsa C 1.2 is 75 bhp, the figure I quoted is wheels horsepower, i.e real horsepower after transmission losses.
Whatever 55 is a percentage of 75 thats your transmission and wheel losses etc.
Some dyno's give flywheel power figures its often a conversion from wheels hp and innacurate.
What I was also asking is as its called XE is it similar, the answer would appear not !
