Sleeving cylinder... Where and ballpark $$$
 

Hi guys. I will be sleeving my 90MM cylinders 1mm to 89MM for my upcoming 2.5L race motor. I have already talked with EBS and they gave me a ball park of $750. I know EBS sends these out to be done. Any other ideas of who I can call for price quotes? I will also be having have the cylinders mooned.
Thanks in advance

I have used ebs for other jobs have always been very happy with their work. Dont pinch pennies for this critical work

Not sure what kind of sleeve material they have. Maybe these guys are worth a look. They've been around a long time.

sleeves make me nervous. the bottoms of the cylinders get really thin when bored out for sleeving. not much support for the sleeve down there. that's where the piston skirt wants to slap the shizzit out of it. seen a few that broke out.

Walker is correct, the cylinder will get quite thin. You woudl be better off Making either an iron or steel cylinder, and pressing on a aluminum heat sink to it, so you arent trying to share wall thickness between the original cylinder and sleeve. Rigidity is an issue, esp in a race motor. Pluys there is an issue in terms of the residual tension from the required interference fit asnd the thermal expansion differences between the iron and aluminum, they need alot to hold, and the thin wall section will make it prone to split.

Although the most expensive route, for reference, LN Engineering manufactures underbores of all mahle cylinders in billet nikasil, including those that were originally cast iron or biral. Makes it really easy to dial in an extact displacment for classes such as 2.5L, without sacrificing cooling or reliability.
