Vauxhall XE (C20XE) Motorsport Engine Upgrade Kits

Suitable for: Vauxhall / Opel XE (C20XE)

All of the kits listed below have been developed for motorsport use. They therefore include a motorsport induction system (see below) and an appropriate DTA engine management system. Ignition is distributorless using a wasted spark twin coil system. The kits include the necessary components to blank off the original distributor.

Carb kits (suffix C)

All carb kits include a pair of Weber 45 DCOW side draught carbs. Suitable jets and chokes are fitted and the kit includes air trumpets and linkages. Also included are a cast aluminium inlet manifold and a carb fitting kit (which includes studs, O ring plates, double coil spring washers and nyloc nuts). A DTA ignition management ECU controls ignition timing and has a two-stage rev limiter, tacho output and shift light control. The ECU is supplied with a wiring loom to connect to the engine.

Injection kits (suffix I)

All injection kits include a pair of QED 45mm direct to head throttle bodies. These come with air trumpets, fuel rail, fuel pressure regulator, throttle position sensor and air temp sensor. A DTA full engine management ECU* controls ignition timing and fuelling and has a two-stage rev limiter, tacho output, fuel pump control, shift light control, and other user configurable features. The ECU is supplied with a wiring loom to connect to the engine.

Q42H – 190 to 200BHP A pair of exchange Q42H profile camshafts, used on standard timing marks, and with standard hydraulic cam followers. A set of race quality rod bolts (for a higher rev limit).

Q38H – 200 to 210BHP A pair of exchange Q38H profile camshafts, used with the standard hydraulic cam followers. A pair of vernier cam pulleys. A set of forged pistons (with deeper valve pockets to suit the cams). A set of race quality rod bolts (for a higher rev limit).

Q420 – 215 to 220BHP A pair of exchange, Q420 profile camshafts (not suitable for the standard hydraulic followers). A set of solid cam follower inserts and shims. A pair of vernier cam pulleys. A set of race quality valve springs (to cope with the higher lift & valve acceleration of the cams). A set of forged pistons (with the deeper valve pockets required for this cam profile). A set of race quality rod bolts (for a higher rev limit).

Q450V – 225 to 245BHP A pair of new, Q450V profile camshafts on new, OE spec blanks. A set of solid cam follower inserts and shims. A pair of vernier cam pulleys. A set of race quality valve springs (to cope with the higher lift & valve acceleration of the cams). A set of forged pistons (with deeper valve pockets & higher CR required for this cam profile). A set of race quality rod bolts (for a higher rev limit).

What’s not included

• Injectors – the standard ones are fine up to 200bhp
• Throttle cable kit
• Air filter and backplate
• Crank sensor (use existing sensor)

*ECU will come loaded with a base map which matches your setup as closely as possible. However, this, as with all generic maps, will still need fine tuning on a dyno.
