We all know Spi 1.4 are s**t, but would fitting a camshaft/cam from a nova 1.4 sr make any difference to the power output?

not really, even if it did then the gain would be minimal and not noticed

Fair enough. I'm just clinging onto some hope of making it faster.
I'm going to have to sell my corsa soon as i bought an spi astra (GF made me do it).

well on my old one i did...
full staight-thru exhaust with decat
head from 1.6i nova gsi
'slightly' adjusted the ignition timing by twisting the dizzy
1.6l injector from C16NZ
popped & banged like a bitch, but was quicker... Could actually keep up with 1.4i SRi's then
engine tho went bang in a blaze of glory & was never more

Just dug up some old threads from Migweb and found this.
'The main restrictions are:-
Extremely mild cam timing
Restrictive exhaust manifold
Conservative ECU map
Restrictive cylinder head
As such, we offer a Stage One tuning kit for your engine that uses a 270
degree camshaft with extra valve lift, plus a modified Vauxhall twin exit
exhaust manifold and tubular downpipe. This produces an extra 16ps and costs
£395.00 including VAT.
A modified airbox with additional cold air pick up and K&N panel filter
gains 3ps and costs £99.50 inc VAT.'

I wasnt planning on doing this, it was jsut an example. I can easily do this air box myself, find a better profile camsahft from an old nova, and a larger throttle body from scrappy.
As explained earlier, a larger engine is not an option
