hi there i have a 1.2 spi nova I have brought a 1.6 cam from an cav, and distubtor would these work or would i need to fit an extrenal fuel pump? Also brought a astra mk3 1.4 spi inlet should i fit the whole unit or swap just the injector? many thanks from leon

what engine code is the cav engine? on some of the 1.6 spi engines, the dizzy is pretty much identical to the 1.2 one.

you only need an external pump if using mpi injection, this is not necessary

please read the guide fully before swapping injectors, theres a good chance the 1.4 is not much different to the 1.2 one..

The inlet and tb are identical on 1.2/1.4 spi engines

Hi I'm thinking of doing this to my 1.2 corsa and was wondering what exhaust manifolds would fit as I thought the nova and corsa exhaust systems we're slighty different appreciate it if someone could let me know cheers

I know the mk3 Astra inlet is ideal but how much different is th e MK4 one?

all 8v corsa manifolds will fit all 8v corsa engines.. so a 1.6 8v would be fine

ok thanks m8

If I updated the cam, would I have to re do the timing as well?

I'm going to do a 1.3 road car with a 32/34 carb what cam could I run and were could I find one or what code do I look for on the cam ?
