Please note; we suggest that at anything over the stock bore of 89 mm be sleeved.
Why should you go with a sleeved block when the 2.5L block already has a 89mm bore size?
We've seen bore distortion with high power n/a engines as well as sub-500hp turbocharged use with un-sleeved 2.5L blocks. After sleeving these same blocks blowby was reduced significantly, the cylinder walls lasted longer, and the engines made more power from the improved ring seal!
