Tu3S And Tu3.2 Head Diffrences?

[Zacky-94 7 2 Cars]

What's the diffeence between the two heads? Are the cam bearing sizes the same EG. are the cams interchangable?, and anyone know the Compression ratio of the tu3.2 std?

 

I take it the Uk 205 rallye engine was the 1360 tu3.2 anyway

Cheers

It's been a long time since I owned any TU engined cars but iirc the engine in the UK rallye is a TU3 F.

 

The cams have the same size journals so is an easy swap. From memory the valve diameters and combustion chambers were the same as the 3S, but I know that the TU3S heads have a "3S" cast in them suggesting a difference.

 

I'm not sure that that was much use really!
