David Mirylees Posted July 9, 2014 Share Posted July 9, 2014 Looking at changing my Dunnell 2.0L Zetec Silver top to a 2.0L Black top. Raceline can supply a crated motor at reasonable cost but what other bits will need to be costed as I understand some of the Dunnell parts will need to be replaced. Has anybody done this 'conversion'? What's the preferred ECU nowadays? (my Silver top runs the basic Dunnell Clubman 2D ECU) As always, any helpful suggestions gratefully received Link to comment Share on other sites More sharing options...
Drumster Posted July 9, 2014 Share Posted July 9, 2014 I can't offer any advice on the changeover, but I've been very happy with my Emerald K6 ECU and I know many others have used the Omex 600. Link to comment Share on other sites More sharing options...
elie boone Posted July 10, 2014 Share Posted July 10, 2014 Why not a Zetec E, Dunnel has a very competitive price for a whole engine here. Link to comment Share on other sites More sharing options...
Molecular--Bob Posted July 10, 2014 Share Posted July 10, 2014 You can re-use your silvertop sump (assuming wet sump), but will need to add a baffle tray kit, which i got from Scholar. This is the baffle tray fitted to the silver top and requires you to fit the longer silvertop studs and some spacers (Scholar or Dunnel)into the blacktop, so you could re-use your silvertop parts i think, fly wheel and clutch should just swap over. You may also need to adjust the angle of the oil pickup as it sits at a different angle in the blacktop. Not sure about alternator fitting, you may need a new bracket, but should be able to re-use your alternator. I run mine on an old DTA e48 (ebay usually has a few) and it does the job, and gives you the option of injection down the line should you want to go that way. You may need new engine mounts, but not sure on this one, Raceline should be able to tell you whether they have changed or not.

zetec Posted July 10, 2014 Share Posted July 10, 2014 I did this very same thing. You will need new Raceline mounts New alternator bracket Aux belt tensioner & belt- maybe an alt pulley ( it runs a different way I think) I went omex 600 with a road loom - loom is (£140). This was miles cheaper than all others & with it mapped I've just returned from an epic Le Mans journey! With no issues- If I can think of anything else I shall post again Link to comment Share on other sites More sharing options...
Molecular--Bob Posted July 10, 2014 Share Posted July 10, 2014 Just remembered that the the pipe from the water pump is a different diameter, and leaves the block at a different angle, so that will need changing as well. Link to comment Share on other sites More sharing options...
