2.0L Vauxhall Valve Train Components
2.0L Vauxhall Valves

SBD has increased its own range of valves and has produced high quality stainless steel race valves for the 2.0L XE engine. The shape has been improved for increased air flow and the valve tip is made from a high specification hardened material to increase valve life. We have had them manufactured in large quantities, which means they are not only very high quality but at an affordable price.

We have produced them in 3 sizes;

Standard size - inlet 33mm & exhaust 29mm.

Oversize +1mm - inlet 34mm & exhaust 30mm.

Oversize +2mm - inlet 35mm & exhaust 31mm.

Valve Guides

Bronze guides are very hard wearing & if you do have a problem with your engine which causes valve to piston contact, the guide may distort slightly, but this is very unlikely to break. Whereas the valve guide made from iron will either crack & fall out at a later date causing a second failure or break into small particles imbedding themselves in the piston & head, so if your budget permits use bronze guides. These guides are direct replacement for the original guide.

Our Competition Bronze Valve Guides for 2.0L XE are manufactured in Colisbro, a higher grade material for added durability, we have also revised several details to aid performance in modern engine builds;

·    Shorter overall length to reduce protrusion into port area
·    Reduced tip height to allow for high lift cam profiles
·    New valve stem oil seal diameter to accept our special compact stem seal, this allows greater clearance when using thicker wire diameter valve springs without interference which is a common problem with original fitment stem seals

The guides are designed for an installed height of 10.5mm, this is measured from the top of the guide to the spring deck of the cylinder head.

Valve Spring, Cap & Platform Set


SBD have designed a new valve spring, cap & platform set for the high specification 2.0L XE engines.  We have used a special steel alloy that has allowed us to produce an ultra-lightweight valve cap, which is stronger and more durable than titanium.  We have managed to make it ultra lightweight due to the strength of the material used.  In combination with our special double valve spring and a new platform to give the correct installed height, the new set will allow for even greater control of the valve train on high performance engines, allowing up to 14.5mm of valve lift with increased durability.
