Can I use 2002tii pistons on non too block? With E12 head?

 

 

 

 

Why guess? Measure!

(I admit - the more failed/crappy engine builds I take apart to fix (including wrong and/or poorly-specified pistons), the less patient I am with guesswork/speculation). -KB

Odd looking piston, #1 compression ring groove is higher up than the original and more distance between it and #2 compression ring groove. Lower skirt is also different looking.

Aftermarket no doubt.

What are they? Just curious.

the higher pop up represents a bump in compression.

Any idea what the CR would be with the Tii piston and a E12 head? 

Manual lists the Tii as 9.5:1 (or 9.0:1 for USA) with the E12 head, and also 10.0:1 for earlier models. 

Are there any specs on the height of the piano top to measure? I have always wondered if my CA '76 has 8.1 or 8.3:1.

Mine are piano tops...but appear to be "baby grands".

Thanks,

John

4 kind of pianos:

1.5-2mm dome but with 1mm recessed top piston to deck, 8:1cr early 74 49 states spec

1.5-2mm dome, 8,3:1cr, us spec, 72-74

4,5mm dome, 9:1cr (us Tii), often confused with real Tii euro pistons

6,8mm dome, 9.5:1 cr (euro Tii)

flat tops on e12 head: 8,1:1, us spec 75 49 states
