Fiat 132 2.0L Cams for 1600 Beta coupe?

[betasulo]

Hi All,

Is it possible to do the above and will it help?. Are the Fiat cams the same as on a 2.0L Beta?

Hi, the cams will fit no problem but they have different timing and lift to beta cams. Is your 1600 a 1585cc or an early 1592cc? The 2l fiat cams are also timed differently to beta 2l cams.

Beta cam timing:
2L: 13/45/49/9 With 9.9 mm. 9.4 mm lift on 1592cc. 1585cc: 17/37/48/6 with 9.4 mm lift

Fiat 131 2L: 5/53/53/5 with 9.9 mm lift.
Fiat 132 2L: 15/55/57/13 with 9.9 mm lift.

There are different cam pulley markings/offsets too which is how the timing is altered on some models.

Confused yet? Is there a specific reason you want to swap cams?

Guy Croft is a very good source of info on camshafts and the twin cam engine.  www.guycroft.com

Hi Ian,

Thanks for all this info.
The plan is to up the performance of my car which is at this time being restored. I hope to get twin Weber carbs and was told the Beta 2.0L cams are the way to go.

I still have a good chance of getting 2.0L Fiat cams and was wondering if it would be the same as the Beta ones.
I will also check which engine I have.

Kind regards

Yes you will get a small increase in power, may be a few BHP, but don't expect miracles from swapping std type cams. the twin carbs are definately a good move, worth about 10 BHP+ on their own if sidedraughts. Head mods and increased compression are the way to go too. I run almost 11:1 CR on my 2 litre still using 98 octane pump fuel.

It may be worth finding a 2 litre motor if you want serious power - just remember you will get greater returns from this motor than the 1600 for the same money spent, and a 2 litre with twin carbs, compression and cams revs just as well as a mildy tweeked 1600 - my 2 litre revs to 7500 no problem!

You can see what mods I have done in the tuning & competition section under 2L uprated engine build.
