1.8L pistons are domed pistons (anyone who has seen one, would agree). The beta I has almost flat pistons.
So if you were to use the beta I pistons on the 1.8 you would drop the compression ratio (im guessing about .5:1) . If you were to place the domed pistons on the 2.0L you would up the compression close to 11:1)

I wouldint consider the 1.8L a beta I..
Different height, different crank, different pistons, different rods..
Although bearings, bolts, gaskets, head, and external parts are the same..
I dunno.. You could argue it either way...

I wanted this post moved BECAUSE of the first question... "whats the difference between beta I and beta II pistons?"
BUT, it was referring to the Tigerlilly Aftermarket pistons.......NOT stock. Which is what you guys were talking about.....maybe the Tigerlilly pistons come w/ diff. comp ratios? maybe they have larger skirts?? etc...
QUOTE (Jaws021)
This question is relevant to the forum and should be answered here by other tuners, and because this question will be asked again in the future.
Yes, it is. And now there are two threads with the same name in different places......this one is still open, the one in kspec is locked.
Its locked so that no more Off-topic posting can occur. So the question can actually be answered.

1.8L Isnt a Beta engine? okay...
Are you even on the right topic? Nope!
Am I the only one confused?
to be honest, the 1.8L was made first, and thats the true beta. The 2.0L was a after thought tongue.gif
Well I am done with this post.
Jaws, lay off the crack man, really. and you need to calm down. You are really throwing off alot of agression.
I checked into some notes I made from talking to random in the past.
And well. The beta 1.8L rods looks to be about 3mm shorter then the beta1 2.0L.
I am still not sure about the the 1.8L dome, but from a past post I saw. Its only a 1mm difference, I dont know how much difference that would make in CR without doing some math. which I just dont care about tongue.gif
But again, Jaws...You really need to touch the topic of the post. And not go off on something else. If you really wanted to dicuss 2.0L and 1.8L pistons you shoulda made another post on your own and not have hijacked mine.
Bad mod! no! Bad mod!

I wouldint consider it a beta I... its a beta.. but not a beta I
call it a beta.. but not a beta I... they are not identical..
Its like calling the CVVT beta a beta II
BUt like i said.. you can argue it either way.. its a matter of opinion

Thats irrelevant as it gets..

Hmmm I never mentioned names or anyone being on crack...

yea i know... shorter block, shorter rods, i said that before..

I didnt do the math.. i estimated..
If you want to confirm the 1.8L dome pistons... just ask random.. easy as that.

Well you asked this..

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?

I answered your first question...
Beta i vs beta ii difference..
eyeroll.gif
Your welcome..
As far as your second question...
Im still willing to bet the beta I and beta II pistons kspec are selling have the same part number..

I was going to lock this, I thought it was getting ugly, but instead I am going to give ONE general warning before I start issuing real warnings.. NO attacks, no flame, and stay on topic.
As for everyone's information. the 1.6 (rare in the US) 1.8 and the 2.0 are ALL betas. It is not the internals that make an engine what it is, but the basic archetecture. While all three engines are different internally and to some extent internally, they are all based off of the same design, just scaled up or down to suit their needs...

So if 1.8 rods are 3 mm thorter, then if we use 1.8L rods with 2.0 crank, block, pistons - we will get 8,5:1 CR.
That would be cheap way to lower compression ratio without spacer.

Dmitry, in the interesting of staying on topic.
I have created a new post.
http://www.rdtiburon.com/forum/showthread....91957#post91957
You never did answer my question, you gave your opinion.And your opinion is not what I wanted. As for if they have the same part number. Well if you would have kept your opinions to yourself we coulda had kspec reply. And its hard for him to post when someone is moving the post to the wrong area!
Let's just stay on topic next time. Okay
Thanks and Your welcome
