VAC Block Sleeving Service, BMW S85

Fri, 15 Aug 2025 08:16:52 GMT

VAC Block Sleeving Service, BMW S85
Buy Now: ~~$5,500.00~~ $4,995.00

Are you planning on boosting your E60 S85 V10 Engine? ... We have you covered!

Although the S85 does not havethick walls in between cylinder bores, it does have one good quality – hardaluminum. If the sleeves are installed properly, the block loses no structuralintegrity. Meaning, the performance sleeves are quite thin, but radicallystronger than the S85 aluminum. Therefore, by installing the thin wall sleevesproperly, the great S85 block is now much more receptive to higher volumes ofboost than the S85 alloy can handle. By simply lining the block with the thinwall, centrifugally spun-cast ductile iron sleeves, the cylinder bores canhandle 50% to 70% more boost than that of the Alusil aluminum bore block.

The boost can care less whatpistons it runs with in most cases. It’s the cylinder block walls that arecompromised first, not pistons. If the S85 block aluminum is poor, it willfracture the block well before the pistons fail. That’s why we like tore-sleeve these alloy blocks ductile iron material. Not to save the pistons,but so the block can hold compression so the pistons do their job properly.

VAC Block Sleeving Service, BMW S68

VAC Block Sleeving Service, BMW S68
Buy Now: ~~$4,400.00~~ $3,995.00

Built for Boost. Engineered for Power.

Are you planning to push serious boost through your S68-powered BMW build?
Then this sleeving service is for YOU.

The BMW S68 engine, while impressive, features lightweight aluminum construction with thin OEM cylinder walls. Under high boost and big power demands, this becomes a weak point--until now.

With VAC Motorsports' world-class Block Sleeving Service, we transform your OEM S68 block into a race-ready foundation capable of handling extreme power, high heat, and long-term abuse--on both street and track.

🔧 Why Sleeve Your BMW S68 Block?

✅ Improved Cooling Efficiency
Optimized heat transfer keeps temps stable under full load.

✅ Superior Structural Strength
Centrifugally cast, ductile iron flanged sleeves reinforce the block and eliminate factory wall weakness.

✅ Increased Horsepower Potential
Safely increase bore size and compression for more torque and higher output.

✅ Superior Oil & Compression Control
Improved ring seal and cylinder integrity for consistent performance and reliability.

✅ Reduced Ring Wear
Smoother surfaces and tighter tolerances extend engine life under high RPM stress.

🛠️ What We Need From You:

Supply your bare S68 engine block with main bearing caps -- VAC will handle everything else in-house with our experienced machinists and BMW engine builders.

This is not a service to trust to a general machine shop. Sleeving is a delicate, high-precision process--and we've seen the damage done by shops who "thought" they could do it. Don't risk your build.

💡 Need More Than Sleeving?

We also offer full lower-end assembly, piston ring gapping, and complete engine builds tailored to your horsepower goals. From 900HP daily drivers to 1,200HP race monsters, VAC builds S68s that last.
