Default RE: cylinder change

The B5234T is based on the B5254 engine.

The B5234T Cylinder capacity is 2319cc with a cylinder diameter of 81mm, stroke of 90mm and a compression ratio 8.5:1.
The B5254 Cylindercapacity is 2435cc with a cylinder diameter of 83mm, stroke of 90mm and a compression ratio of 10.5:1.

The cylinder head for the B5324T is Volvo part # 8111178 which is also listed as a replacement part fo the B5254 engine. However, several other heads are listed for the latter so you will need to find the head part number to be sure.
