BMW E9 3.0 CSi Restomod

BMW E9 restomod

We started this classic BMW E9 restomod project just over a year ago. The premise was to restore the car to look close to standard but include subtle modifications for performance, reliability and drivability. The very definition of a ‘Restomod’.

The exterior was finished in BMW Altantic Blue and remains understated. The original 14″ Alpina wheels were retained rather than an unnecessary increase in diameter. The suspension was rebuilt and treated to a set of Bilstien Sport shock absorbers. Additionally, a set of subtly lowered springs were installed. The 4 speed gearbox was swapped out for a 5-speed and a LSD was installed at the back.

Under the bonnet you will now find a M30B35 3.5 litre straight six engine from the 635. It has been modified with a ported cylinder head, Schrick 284 camshaft and a balanced rotating assembly. The engine is fed through an individual throttle body (ITB) fuel injection system from Jenvey with an Emerald ECU.

Lastly, the interior. SM Trimming did a fabulous job trimming the interior in a tobacco brown leather with custom carpet set. They also restored the dashboard and all of the wood paneling.

The end result is a car that is magnificent to drive. And, in contrast to the understated classy looks, the six cylinder sound track from the ITB injection is raucous. The perfect juxtaposition for this BMW E9 restomod.

BMW 3.0 CSi. E9 Fast Road Rebuild

The BMW E9 fast road project has come a long way in recent weeks and its really beginning to take shape. The B35 engine is in and the new ITB fuel injection system has been installed. The car will be running a triple set of Jenvey Dynamics throttle bodies and an Emerald ECU. We’ve fitted a set of Bilstein shock absorbers because they offer great performance with being harsh. It has also received uprated springs and poly suspension bushes. Next up is the 5-speed gearbox conversion and to finish of the engine install. Then the car goes off for new carpet and interior trimming in brown leather.
