I have started to rebuild a B5244T5 engine from a 2006 S60T5. Due to bore ovality and piston wear i need some oversize pistons and when looking in VIDA it states that the only part no. is 274534 which is a + 0.4mm 0S.
When looking on the 2.3 T5 engines from 2000-2005 it states that there are 2 OS pistons available +0.20mm and +0.40mm.
Both types of engines have a standard bore of 81mm and 23mm wristpins. The only difference is the longer stroke on the 2.4T5.
Can anyone know what is the difference between the pistons form the 2.3T5 and later 2.4T5.
