They will fit in the bores, but compression will be affected.

Tried and tested no problems!
Just shave the piston crown to have a CR of around 8.5:1
Tested with NPR rings and 0.8bar no problems whatsoever

Skalabala, please can i have some more information about the 5e pistons. i am considering this option but need to be 100% sure it will be no
problems. ie how much did you take off the 5e pistons and what distance is the gudgen pin to crown. some pics would be very helpfull.. thanks

Do not have any pictures sorry
They are the same as 4EFTE pistons, they just have a dome.
If I remember correctly you just cut the dome off and you will have a CR of 8.5:1
Compression height is 30mm
Go for Hastings crome rings, they are better than OEM rings

A place like that won't sell junk
Just get the lowest CR 5E pistons, like do not get FHE pistons.
The lower the standard CR the more meat will be left after cutting the piston.
I would also recommend you to go oversize and a re bore with correct P-W clearance
