Silsleeve cylinder replacement
The existing Lokasil liners are machined out and replaced by steel liners plated with the well proven low-friction Nikasil running surface. These SilSleeve liners are specially designed to have a top flange which provides more support at the mating face with the cylinder heads, known as a closed-deck construction

Intermediate shaft replacement
For the current 997, Porsche introduced their 5^th upgrade for the Intermediate shaft, this using a larger bearing as well as the more substantial rear oil seal to stop leaks in this area. As this latest shaft won't fit the pre-2001 engines, Autofarm have designed a simple conversion to utilise this technology in all 1997-2000 engines

'Big-Bore' conversions
By using Silsleeve liners Autofarm are now able to provide several options for substantial capacity increases:

2000-on Boxster 2.7 to 3.0 litres
1998-2001 996 3.4 to 3.7 litres
2000-on Boxster S 3.2 out to 3.7 litres
2002-2005 996 3.6 out to 3.9 litres

Rebuilt engines come with (where relevant):

Silsleeve rebuilt cylinder block
New piston rings for the Nikasil bores
Our modified intermediate shaft (for pre-2001 engines)
The latest 997 intermediate shaft (for 2002-on engines)
Updated intermediate shaft chain tensioner
New Variocam chain guides
The latest Variocam solenoids
Cylinder heads and valves reconditioned as necessary back to manufacturer's tolerances
All new main and big-end bearings and big-end bolts
All 24 new cylinder head to crank carrier bolts
All of the latest seals (including the RMS) and gaskets
All other wear items, e.g. chain guides, checked and replaced as necessary
Pistons are replaced only if necessary (rarely needed); otherwise the original items are simply fitted with new rings to the correct specification.

Terminology:

'Short block'. A fully built-up cylinder block assembly, less cylinder heads.
'Long block'. A fully built-up engine, less ancillaries, manifolds, flywheel, clutch, looms, etc
'Exchange'. Exchange cylinder blocks, short, long or full engines must be on a same model like-for-like basis, though same model year not required.
