i think its a case of measuring the engine in the e36 and seeing exactly the space required im using the 325 lump in mine.
Chris's brother in law i think is putting a 525 engine in a roadster hopefully more information will come soon |

Hi Chris, I was wondering if you built a 5 series based roadster and if so, could you give me some advice. I have ordered the steel for the chassis and I have a 1993 518i waiting to be stripped in the drive.

surely it is possible to just modify the chassis in order to just accept the engine and transmission, possibly have a custom prob made up and mate to sierra diff. and normal suspension?
If you do go to the lengths o using as much from a BMW as pos, then I think that is no mean feat but will require alot of time and effort and drawing board time. As I've said in another post about donors, sierras are getting thin on the ground to find in some places and not others, but BMWs and co do appear to be in more plentiful supply, but are the tuning options as competitive as all the ford ones? Would be interested to see what the differences are and adv/disadvantages are of a BMW build... would see a new book or a supplement to loval readers should they fancy a go Chris? |

Hello Salona,
I've helped with BMW 5 series Roadster which you can see here http://www.haynes.co.uk/forums/showthread.php?t=119 As you can see this car was made much wider to fit the 2.5 straight six but the four cylinder engines will fit in the standard chassis, the gear box would require modification to the chassis, similar to the MT75 mods here http://www.haynes.co.uk/forums/showthread.php?t=53 The front and rear hubs are substantialy different to the Sierra set up. The fronts require a fabrication like this http://i126.photobucket.com/albums/p...ntupright4.jpg This would bolt to the fixings for the front strut I haven't done any analysis on geometry yet, it may be some time as I'm right in the middle of a new book. At the rear the rear hubs bearings are part of the huge and unusable trailing arm, I think ther best way to deal with this would be to make (or have made) a bearing carrier to receive the hubs which would bolt to the rear upright like the Sierra. I'd ask on the forum too, I know some builders are using BMW bits and might have some more practical advice for you. If you need anything else don't hesitate to get in touch, I'm here most days Cheers Chris |
