Picture of the STi 240mm flywheel added.

03/11/05 - Web Site Finally On Line - RJES.COM V1.01!
   After two years of collecting information as I have developed the products on this site, I have finally got something on line. Thanks to everyone who has helped with the development of both the parts and the site.. The intention for the site is for it to become the ultimate resource for technical information on the details of installing Subaru engines into VW’s. There’s a long way to go yet to get there, but this is a start.
   The emphasis will be on well engineered, proven solutions to the problems surrounding Subaru engine conversions. If you have such information on any aspect of the conversions, either on your web site, or on paper, which you want publishing), please contact us. We maybe interested in either adding it to the site, with a ‘Thanks to XXXXXX’ note, or linking to it.
   I think I have put links on the links page everyone I’ve been in contact with who has a relevant web site. I’ I’ve missed you out, or you would like a (relevant) link on out page, please e-mail. Thanks

03/11/05 - Bellhousings temporarily out of stock soon.
    Due to the large demand since Vanfest, and the small initial batch size, there are only two bellhousing in stock. It will be a month or two before the next batch are finished. Very sorry for the delay. the next batch is much bigger.

03/11/05 - Anyone interested in building / modifying wiring harnesses?
   We’re after somebody, preferably in the North Staffordshire area, who is interested on taking on the job of stripping out everything but the parts which are needed to make the engine run from Subaru harnesses. You’ll need a good knowledge of engine management and have experience of high quality harness building. Unfortunately, new harnesses for conversions can not be built from scratch, doe to the vast amount of unusual connectors which Subaru use. The old ones have to be recycled. OBD II knowledge would be a benefit too.
   If you are interested, please contact us, or if you know anyone who may be interested, please pass on the details. The work will be on an as and when basis, and would maybe suit someone who has retired, or who is looking for a bit of extra work. You would need to have the facilities for the work yourself, as we have no premises which you could do the work in.
   The work would involve receiving the entire harness from the front of a Subaru, with everything still attached, working out what is and is not required. and and making an ‘engine only’ harness. This can involve sorting out factory fitted Thatcham Cat 1 immobilisers. These can not be removed - they have to be kept intact with the rest of the engine harness. I would work with you on the first few, but I don’t have time to do this work regularly.
