Hi Farrar I doubt that very much. Odd or even firing is related to the crank, and where each piston is in relation to the others - ie in an even fire, each one will be 60 or maybe 120 degrees out from the next. This in turn affects the valve timing and therefore the cams. To convert from Odd to even you'd need to re-fit the crank and cams before the dizzy. As my guy has pointed out, the crank in the even fire engies cannot be dropped into the DMC's block - the bearings are different (If I remember correctly). NOW, can anyone help with whether the 3 litre pistons are heavier, lighter or the same weight a the 2.85's? If they weigh the same or ar heaver (and can be lightened), you can use them on an odd-fire crank and pull the capacity out to 3 litres. Talking distributors - if you remove the lambda system on the DMC's engine, you're not doing yourself half as much a favour as you could by replacing the distributor with one from a Renault 30 - apparently the curve on a lambda-equipped PRV is quite different.... Martin #1458 #4426 (engine being built without lambda system, but otherwise identical) Original Message: ----------------- From: Farrar Hudkins fhudkins@xxxx Contact Pacific Rim Automotive - they used to have a kit which would convert the DeLorean's odd-firing distributor to an even-firing one. -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
