Every now and then a project born in Scandinavia catches my attention. Car purists look away, because this is a BMW E30 turbo that shares it’s looks with an M3. Stig , not the one from Topgear, loved the classic look of the BMW E30 but wanted to benefit from updated technology and performance. Stig is 25 and was born in Norway.
This project started out as a ’86 325i that Stig bought last year. He swapped the engine with a 3.5 litre S38B36 from a E34 M5 and modified it. The block add-ons include a polished crank, forged H-beam rods and CP forged pistons with heavy duty pins. Also the valvetrain has received new updated springs and retainers. The fuel system mods are twin Bosch 044 fuel pumps, a Nuke Performance Blackline fuel rail, Precision 1,260cc injectors and an Aeromotive adjustable fuel pressure regulator. That’s a lot of gas. The engine management is taken care by the Electromotive Tec2 unit. This engine cools via a Davies Craig electric water pump and fan with a controller.
Before I say more, I must note that the biggest hint that this car means business is the front mounted intercooler with 3′ pipes. Of course there is a turbo, a BorgWarner S475 race unit that sits on a custom manifold made by JAAS Performance. Gas flows into a 4′ downpipe and out of a 3.5′ exhaust system. When boost pressure is set to 1.7 bar , the engine puts out around 900 rwhp.
Of course the drivetrain was also upgraded and now includes a E39 5 series diesel gearbox, a twin clutch rally spec plate from Tilton and a E28 M5 sourced differential with heavy duty axles made by PPF while the gearbox sits on GS Performance mounts. The suspension is comprised of K-Sport adjustable coilovers and Powerflex polyurethane bushings.
Stig decided to get some period correct wheels for the car, so it sits on an OZ Hartge wheel set. They measure 9.5×17′ upfront and 11×17′ in the rear, with 215/40R17 Toyo T1R and 245/35R17 Hankook S1 Evo tires respectively. If you look past the spokes of the OZ wheels you will see the upgraded braking system that includes a 330mm K-Sport setup upfront and OEM E28 M5 brakes in the back.
Exterior modifications, apart from the M3 look, are very subtle: a M3 Sport Evo front spoiler, a set of DTM carbon fiber side mirrors and new Hella lights. In the back there is a carbon fiber rear spoiler and Started taillights. Interior mods are a little more noticeable, with a rollcage and Sabelt racer bucket seats.
