New camshaft for a 1.2

[valentinosebby]

I read in my Haynes manual that for a Nova, such as mine (1.2), a GTE camshaft will be easy to switch with my current one and it will run well. I came across a 1.6 Injection camshaft in a breakers yard and was wondering if this will be as easy to switch and run as well as the GTE shaft.

Thankyou

definitly, imo, for a 1.2, theres no point going all out on it, a GTE cam will do fine, and you will gain a noticeable difference!

is your nova a carb or spi?

[valentinosebby]

its got a carb. will that make a difference?

[Aragorn]

u may need to find a 1.4 sr cam

the gte cam prolly wont have the pump drive lobe or the fuel pump

[Ste_Nova]

i have a 1.4sr cam that i need to get rid of

[Aragorn]

well there u go

14sr is a bit better too - it has higher lift on the exhaust valve

[valentinosebby]

So is a 1.4 sr cam better than both a GTE cam and this other 1.6 injection cam i found?

[Aragorn]

yup and it defo has the fuel pump drive u need

Does anyone know the duration of the 1.4 and 1.6 cams? In the performance cam world, higher lift isn't always better, duration plays a big role.

on a very rapid and not overly accurate measurement i did on a 14NV cam nearly a year ago its about a 240 deg duration, and id assume the 1.6 is a similar figure too.

only major diff will be the intake/exhaust overlap times

i have the same nova 1.2 with a carb and i was looking for a new cam and a mate said to go for a 1.4 sr for acceleration, which is what im really after. will this do the job?

[valentinosebby]

thanks for the info guys. it just so happens that in the breakers where i found the 1.6 injection shaft, they'v just got in a 1.4sr in so i may go hav a browse. how much should i be expectin to pay for it? this ones done quite a few miles (about 110,000).

You might end up losing performance if you fit cams that are that old?

[Tazzy]

ok, so i have a 1.2i, and have found a 1.6 gte cam im interested in buying!

should i still buy it?

cheerz!

Look at it this way, 1mm of wear on an old cam or follower looses 1mm of lift. Followers normally wear quicker than cams, and most followers in a 15 year old engine will be pretty worn. Just fitting new followers will gain power!

Slim Jim is selling a piper 285 cam, nearly new with numbered followers for ?100. I'd recommend it.
