CLICK TO ENLARGE:

Fueling sorted and rev limiter raised at Chip Wizards rolling road.

Engine bay = clean.

Engine finally together after dummy building, tuned for more torque.  Block painted a light colour for early fault detection.

Flywheel lightened and crank balanced.

The long guide on the left and the corresponding one in the head (not shown) were worn out after 100,000miles, although the rest of the engine components were very good. 

Elongated holes to swing cam timing into the correct position.  Cams then re-dowelled.

Bigger 5 stud hubs and larger bearings taken from E30 M3.  Surprisingly powerful calipers taken from 635CSi probably helped by weight loss.  These calipers are identical to the E30 M3 but have a 57mm pistons instead of 54mm. 

BMW Motorsport spent a bit of time developing the suspension on these cars for Group N racing, so we started with a rebuilt set re-valved for our use.

Parallel springs and strengthened anti-roll bar mounts. 

Early warning, safety systems and extra gauges fitted. 

All unnecessary items removed or lightened.  Alpha-N box on the left and roll cage tied to pillars.

Gravity fed pump via. sump in tank on trial, no problems yet. 

Bruvsmotorworks bias braking pedal box.  

Pedal box very tight for space, cranked pedal to avoid skimming the steering column.

Bruvsmotorworks engine mounts ensure a positively located motor, vibration free Via. hard metalastic bushes.

Bruvsmotorworks gearbox x-member with e36m3 mount help out the harder 635CSi mounts.

Thanks to all the BMW websites around the world for the information and research we have gleaned.
