I'm interested in the Marlin 5exi mid-engined kit car and may start building in late 2005 / early 2006.
This kit is based on the Rover 200 series of hatchback which uses the same Rover K-series engine as the Lotus Elise and MG's MGB, but is lighter than either, weighing in at about 600kg.
There's quite a bit of information about tuning this engine at Dave Andrew's site http://members.aol.com/DVAndrews/kengine.htm but all his tuning kits reflect the £500 cost of an Emerald ECU. I'd be extremely interested to hear of anyone using VEMS with one of these engines - please email me at stroller@stellar.eclipse.co.uk
