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?

pretty sure that they are exactly the same man.

they are not identical.

they are interchangeable.

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

So what is the difference ^^

That is what I want to know.

delete, sorry.

couldnt get on webtech but carpoint says

3.23 X 3.68 beta1 bore & stroke
3.22 X 3.68 beta2 bore & stroke

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.

Compression difference?

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?
