Modifying the IRS for a North American donor.
Last month while I was in the UK I had the great pleasure of visiting Saturn Sports Cars.
( I just happened to be in Hartlepool because that’s were my father’s family is from.) I was given a remarkable ride in one of their cars: http://www.youtube.com/watch?v=iSeE-dkV4cg I am currently building a Locost here in Toronto and have been searching for a solid axle but after seeing the Haynes Roadster in person I am really interested in using the IRS design from it. The Sierra ( aka Merkur) rear diff is very had to come by here and they were never produced in a limited slip version in North America. Any suggestions for alternative donors that would be found here? I am wondering if Nissan 240SX diff would work. Similar size and weight but slightly different drive shafts arrangement. |

I dont know the Nissan that well but with a bit of thought I'm sure it will be do'able. |

A Merkur Scorpio would be fine.
MK5's have been talked about But E30/36 is the main alternate choice. TT

Mazda Miata MX5 is a popular donor. I'm using an XR4Ti. There are several aftermarket LSD replacements for the Ford 7.5" diffs

Do you have any links or builders logs where I can learn more about using the BMW rear end? |

I am using a Nissan R200 lsd in my build.. ratios are available from 3.5 to 4.8 and viscous LSD centers are very cheap. Problem is, it is very heavy.. about 40kgs.
I am about to replace it with a subaru R160 lsd. This weighs 22kgs. In the USA you should be able to find plenty of Subaru diffs in a wide range of ratios. Hope this helps. http://lotus7.co.nz/forum/viewtopic.php?f=16&t=72 |
