14se head on 1.2

[jimbob-mcgrew]

who's tried this ?

did you have to change the piston heads to bring the comp back up ?

[Stuart]

you'd want to measure the compression ratio and then have the head skimmed to suit a better CR (if it was much under 9.5:1 imho )

it will be low on a std 1.2, but if for example, on a 1.3 with a rebore & 1.2 pistons, it would be quite good

[jimbob-mcgrew]

how about 1.4 flat top pistons in the 1.2 to bring the comp up ?

there only 0.2mm smaller bore, with new rings, might be ok ?

[mowgli]

its the lack of stroke that causes the lack of compression

[jimbob-mcgrew]

ah right.
short stroke = poo i guess

ill scrap that idea lol

cheers

[Stuart]

short stoke is good for revs etc.

its the "possibly" larger conbustion chamber from the 1400 head that would cause issues

[burgo]

It is much larger. Would need a fair chunk skimming off
