Default Beta1 vs Beta2 pistons
What is the difference between the Beta1 and beta2 piston?


Most USA oem parts claim them to be interchangable.

so what has tigerlilly changed to clarify a difference between the two piston types?

they are not identical.

they are interchangeable.

I currently have the beta II pistons on a beta I block, crank, and rods.

I am thinking it a differen valve relief.

Since the beta 2 is MLA. They may need a deeper valve releif.


My wish list would say, they move the pivot point of the pivot high up to the top, so they use a longer rod and means a better rod/stroke ratio smile.gif


but no one seems to know 02.gif

I am starting to think its just a marketing thing for the idiot impaired. They could be the same piston.

They are not identical.. but swappable..

Like i said.. i have beta II pistons on a beta I block, rod, crank, in the same bore,..

Larry:
The compression is raised slightly.. just by looking at the two pistons..

Slightly ...more or less than with 1.8l pistons in a beta1?
