ECR Posted March 13, 2007 Share Posted March 13, 2007 On behalf of a non member trying to buy a car. "However I have one question, how easy/expensive is it to convert a 1.6 supersport engine, (which would come with a 1.6 Superlight). Into a 190BHP+ I assume one would increase it to 1.8 or 1.9 first. Which is the most cost effective Convert a Roadsport to a Superlight or Engine work on a 1.6 to get the required BHP? " Ex Chairman Roger Link to comment Share on other sites More sharing options...
Graham King Posted March 13, 2007 Share Posted March 13, 2007 ECR, probably depends on the spec of the Roadsport to start with but I suspect that a general answer would be that it would be much cheaper and easier to do the engine work on a genuine Superlight with all the nice bits as opposed to buying a Roadsport and having to add 6-Speed, LSD, Big Brakes, Adjustable Suspension and still have to do some engine work. I think 190BHP can be had for about 3-4K from looking at DVA website. Graham. R7 GPK Superlight #85 Link to comment Share on other sites More sharing options...
mav Posted March 13, 2007 Share Posted March 13, 2007 Roger, Unless they have a burning desire to do the conversion themselves, then I'd go for an SLR / R400 straight off... Link to comment Share on other sites More sharing options...
davef Posted March 13, 2007 Share Posted March 13, 2007 The route I went was to buy a R400/dry sump installation and swap it into my Superlight. Easy, and I think fairly cost effective. OTOH I wish I had bought a R400 or more likely a SLR from the start - probably not much more expensive overall, and of course it would be the genuine article.

David Ward Posted March 13, 2007 Share Posted March 13, 2007 Wrong route! I bought a nice 1.6 supersport and then spent 5 years upgrading to get to what is effectively an R500 equivalent (DVA 1.9 etc ...). At one stage it went through a very effective >200 bhp 1.7 phase but with an expensive DK crank and the rest... Start with an SLR/R400 and it is all a lot less hassle! 😬 V7 HPD Link to comment Share on other sites More sharing options...
Rob Walker Posted March 14, 2007 Share Posted March 14, 2007 190 bhp is possible from a 1.6 without much hassle. I ran a 186bhp 1.6k for two years it was a great little engine. Basically its was just a ported head with slightly enlarge valves running on the standard valve inserts,Piper 740 cams, TBS and an Emerald ecu. IMO the 1.6 is a much sweeter engine to tune. I did an article for low flying ( DIY VHPD) detailing the work. Link to comment Share on other sites More sharing options...
