90.5 Case

Stronger than the stock magnesium alloy case therefore it will withstand more abuse in high powered applications. 8mm Case Savers, cut for grooved cam plug, pick-up tube installed. I can bore and machine these cases for all popular bore and stroke combinations. Price is for standard 1600cc bore.
Genuine VW 8mm cylinder head stud kit
The best quality head stud you can use on any street driven engine. Unlike chromoly, the genuine VW head stud material is designed to cope with the thousands of expansion and contraction cycles your engine goes through during the course of its life without losing their torque setting. Also vastly superior in quality and tensile strength to the inferior and inexpensive head stud kits sold as 'stock' by others.
Chromoly head studs - 8mm, plus 12mm
These studs are half an inch longer than stock so are suited to engines using long stroke/long rod combinations. Black coated and supplied with hardened washers and hex nuts. Suitable for engines running forced induction i.e. nitrous, supercharger or turbo.
Chromoly head studs, 8mm , stock length
145,000psi tensile strength. Black coated. Supplied with correct thickness washers and 15mm nuts. Suitable for normally aspirated engines or forced induction i.e. nitrous, supercharger or turbo.
Chromoly head studs - 10mm
As above but in larger 10mm size. For the ultimate in strength. Generally used on turbocharged or nitrous injected engines
Cylinder head nut and washer set - 8mm
Don't need head studs but you've lost some of those hard to find nuts and washers? A full set of 16 special thick head washers and those 8mm/15mm spanner size nuts
Universal case fitting kit
Contains oil pressure relief valves, springs and plugs, oil and fuel pump studs, oil cooler mounting stud, lower bellhousing studs, type 3 dipstick block off plate. These are the pieces you don't get with a new case.
Type 3 block off plate
If you already have most of the parts contained in the universal case fitting kit, you probably haven't got one of these. Blocks of the oil filler-dipstick hole on type 3 and universal cases
Main bearing dowel pins
Set of five - enough for one engine build
Deluxe crankcase nut & bolt kit
All the nuts, bolts and washers you need to bolt your case halves together. Also comes with a full set of cylinder head nuts and washers, oil pump nuts. Great value.
Cam plug
New cam plug. Fits most cases
Cam plug - rubber
Some new cases don't have the groove for the steel cam plug and use this rubber seal instead.This is it.
Engine gasket kit
Good quality gasket kit. Has everything you need apart from the flywheel oil seal
Hylomar case jointing compound
This is what we use for sealing the two case halves together. One tube will do several engines. It never fully sets, making an ideal leak-proof seal.
High temp silicon sealant
Withstands high temperatures of the aircooled engine. Great for sealing cylinder bases to the case, oil pump to case and rocker gaskets to rocker covers.
