S50 Engine

(sold as a swap or separately)

Introduced to the US in 1995, BMW did what they do best, a Natural Aspirated Inline Six, High Revving Lightweight Motor producing up to 240 HP (@6000 RPM) and 225 lb-ft of torque (@3800). Drop this engine into your beloved E30 or E36, and you'll get a Lightweight Easy To Tune Machine thanks to the simple OBD1 System and Single Vanos Reliability just a Straightforward Motor. Pure Raspy Six Cylinder Melody don't be afraid to redline this beast ​(after break-in​) to hear it sing... or scream.

the big three

S52 Engine

(sold as a swap or separately)

Developed in 1996, a Naturally Aspirated inline six engine that produces up to 240 HP (@6000 RPM) and 236 lb-ft of Torque (@3800 RPM). Don’t let the number fool you, fitted in an E30, this engine is no joke. The lightweight nature of an E30 and the raw power of an S52 simply produce a beast, whether it’s driven on the streets or on a track, it's purely a masterpiece with reliability and the ability to modify. You can’t go wrong with this engine.

Do you think the S50 or S52 won’t be enough? Don’t worry, settle on an S54 instead. Another High revving Naturally Aspirated inline six engine developed by BMW, but with more kick. Developed in 2000 by some German Engineers with a little too much caffeine in their system, you get a 333 HP (@7,900 RPM) engine with 262 lb-ft (@4,500 RPM), and with a max Redline of 8,000 RPM, this will surely rip the asphalt off the road, fitted in your E30, E36, or whatever you want it dropped in.
