so what would you have skimmed of the 1.4 multi point injection head to make a safe compression ratio
also what kind of lift dothe cams have on them

As someone who did the 1.2-1.4 conversion, the pistons need pocketing...
I actually did the old fashioned method of measuring all of the bits with a drilled perspex sheet & a syringe then did the sums...
then just to make sure, I measured a photo in an old copy of CCC mag with an article about PMC producing the conversion.. the numbers worked out the same, it was something like a 6mm dish. very similar to the old 1.3 low comp pistons.. the engineering firm would never charge me for doing them cos they didn't want to be held liable.
as for the lazy engine comment... it just had bags of torque. I never tried the big cam etc.
the other thing about doing it to a 1.2/1.3 as opposed to using a 1.4 is that there is no risk of needing to fit an f13 box
mowglie do you stilll need to pocket the pistons if you start witha 1.2 block and pistons and use the 1.2 cylinder head and just change the crankshaft and con-rods
i really want to try this, but im struggling to find the parts to do it (funny that.)Quote:

if you are struggling i belive the 1.3 crankshaft and rods can also be found in the 1.3 carb astras
lol they are rarer than 1.3 novasQuote:

just need to find a crank.
ive got a 1992 1.2i and i know this is a stupid thing to say but it appears that the engine is missing some thing ,now ive looked at other engine bays and they have a fuel pump or oil pump correct me if im wrong at on the end by the cam it looks like suttin was there but i bought the car like this and its just looks suspect but it does run well not now becauce it creamed up and sprayed all over the bay lol so if some one could send me a private message or post it on this thread id be grateful cheers
what would you like me to put in your private message? iam scared with your wordage.
you are correct in that some novas have a fuel pump at the end of the cam carrier. however being as yours is an injection it has the fuel pump inside the fuel tank. so you have nothing to worry about with that
