Super ETA verification

from memory they are different, check out realoem P/N's

So I am gathering parts and ordering rebuild pieces. Would the piston rings be the same as the 2.5l as its the same bore?

[turbski]

cool. thanks for the info

[digger]

Reasons are
- pistons are not a few mm down bore like it would with 130 rod, 81 stroke and b25 piston
- reliefs are shallower than b25
- raised squish area similar to b25 but is smaller radially

[turbski]

Last question. For future reference. What about the piston protrusion tells ya what your looking at. This is purely a question of wanting to learn more.

[turbski]

all the research ive done along with measurments seem legit, thanks for helping to verify. big help. off to the machine shop it goes!

[digger]

Yeah pretty certain it's a SET

[turbski]

not the best but shows how far the crown is out of the block and the edge of the piston as well if that's what your looking for

[digger]

Yeah I mean the edge of piston not the very top of crown

[turbski]

With reference to? Lol super slow I am

[turbski]

At top dead center the piston protrudes a bit. What is w r t

[digger]

looks like seta slugs which are b25 but valve reliefs smaller. Can you put cylinder 1 at tdc and take pic so we can see if it sits low w.r.t deck

[turbski]

Does this sound correct?

[turbski]

success i think

Ok so with the head off I took some quick measurements of the bore and stroke within the accuracy of my digital calipers. Bore is 84mm.
stroke was a bit harder as the piston sits above the top of block, at the lowest point it is 1.19mm above, made a mark on piston and turned it down to BDC. measurement to the mark was 80mm add the 1.19mm above gives a stroke of 81mm+-. from the reading im doing the 2.5 had a stroke of 75mm and the 2.7 has a stroke of 81mm

this leads me to believe this is a seta based on these results and the head set up. please correct me if I am wrong.

Thanks!

Check stroke*
