Over $43,697 invested - in Brand new Components , not including the car - have all receipts from 425 motorsports 1978 BMW E21 - Group 5 Racing Kit - E46 M3 Turbo Running Gear This project car was designed and built to be a trackable, streetable, modern powerplant driven Group 5 replica racing car. Group 5 was a FIA racing class from the late 60s to early 80s, with the BMW 320i racing alongside Ford Capris, BMW M1s, Porsche 935s and others. This project was undertaken by the owner and also work employed through 425 Motorsports in Kirkland, WA. A professional chassis designer was hired through 425 to fabricate the suspension and frame/roll cage so as to accommodate the E46 M3 drivetrain (engine, transmission, rear differential) and suspension. Custom made M3 Ohlins dampers with Eibach springs sit at all 4 corners. Over 25k(?) was spent on suspension and cage work alone. The S54 motor is intended to be turbocharged, making reliable, pump gas driven, HP numbers in the 7-800s. A top mount DOC Racing exhaust manifold with custom dual wastegates and HPF Racing intake manifold help make this possible. Some of the components that were designed into the build but not yet purchased are: AEM Infinity standalone engine management and AiM MXG display. There are many reasons these are a best option; including being able to read and utilize the stock E46 wheel sensors thus enabling the possibility of adjustable traction control. Additionally, these power numbers are possible on a stock motor but it would be best to remachine and reduce compression. Contact info for one of the most experienced engine builders for the S54 can be provided. HP numbers in the 4-500 whp range on a stock turbo S54 are reliably doable. The fiberglass Group 5 accurate body kit is handmade from Europe. After years of searching this was the only product to be found anywhere, there are no suppliers or manufacturers for this kit in the US and this was the first of its kind shipped outside of Europe. This kit is truly one of a kind! Additional parts that included: ? {Seats} ? {Steering Wheel} ? CAE Ultra E46 M3 Shifter - https://cae-racing.de/CAE-Ultra-Shifter_1890 ? {18” wheels} ? OEM Dash ? OEM lights ? OEM front lip ? OEM frame & engine wiring harness ? The bones are here for a very bespoke, well designed 70s racing replica with modern tech. The chassis can accommodate a variety of powerplants and the build is early enough on, that much can be customized to your needs and wants! 1978 E21 with full tube frame chassis S54 with Turbo intake and Exhaust manifolds (DOC top mount 7 HPF black powder coated) E46 M3 front and rear suspension w/custom Ohlins Shocks & Eibach Springs E36 M3 5 Speed (ZF) Full Group 5 Fiberglass widebody kit CAE Ultra Shifter - E46 M3 2 Sparco EVO II Seats
