View Full Version : Sleeving the block ?

10-21-2004, 09:45 PM
Hey guys, im rebuilding my motor at the moment to support about 450rwhp..
Cylinder 1 has been scored and needs boreing out, would it be better to re-sleeve the block than bore it out ?

depends how severe your scratch is.. i had to bore to 86.5mm. scratch went away.

ive been told that stock sleeve can be bored to 87mm
but i wouldnt try that if it were to surpass anything beyond stock use.

I had mine bored out to 87mm with no problems for 5 years. my last dyno was 494 rwhp. but that engine is now blown due to crank walk
