I.Mupferit Posted April 17, 2001 Share Posted April 17, 2001 Steve, Not sure of the exact weight of the Zetec; all I know is that it is slightly heavier than the X/Flow but lighter than the Vx. There was a thread on this some time ago which showed the exact weights but I have been unable to locate it. Michael Hi, Don't worry about the 'K' comparisons, just a long running, but always friendly, rivalry between Chris & myself. Besides, he knows when he's been beat! smile.gif thumbsup.gif I will hopefully mail you tomorrow with the address we are staying at, will you be able to come down?

millsn Posted April 17, 2001 Share Posted April 17, 2001 What do Dunnell do to their engines? I think that they alter the tappet design and fit a differently machined cam (although the profile is supopsed to be the same). Their sump is obviously baffled and modified (wider, lower) and you get a dipstick recalibrated. You also get a bespoke ECU if ordered and they'll set the carbs up for you with correct progression drillings. You get a nice manual style folder and bits n bobs and a power curve. Personally, I'd go for weber alpha's ECU as it seems simpler to fit, and I'd use JWhiting for all the bits that you fit to it (for reasons of local tech support). I have an all Dunnell set up. Don't forget to remove all those crossflow bits that aren't engine though as I forgot and it cost a fortune to replace. Why diodn't Caterham fit one: I'm advised that they trialled what they asked Ford for, which was not a zetec. They asked for a part number and got it. It was actually a late twin cam 2.0 ltr from a Sierra which was too big for the 7, put out low power and was rough- wasn't a zetec.

allen Posted April 23, 2001 Share Posted April 23, 2001 Bit late coming in on this one - been on holiday - according to James Whitting, Zetec is 20 Kilos heavier than the xflow. Use James, very helpful, will not sell you kit you don't neeed (i.e. sump gasket - it re-uses many times). Very glad I converted Regards, Allen Link to comment Share on other sites More sharing options...

NickW Posted May 22, 2001 Share Posted May 22, 2001 Hope this isn't a stupid comment but, aren't the later Zetec's all alloy? Nick. Link to comment Share on other sites More sharing options...
NickW Posted May 22, 2001 Share Posted May 22, 2001 Yes, it was a stupid reply. The new engine is a Duratec-HE, probably a bit too new? Ooops, sorry. Nick. Link to comment Share on other sites More sharing options...
James Rogers Posted May 22, 2001 Share Posted May 22, 2001 Have been told that only the earlier pre 99 Zetecs should be used because the newer lifters are not compatible with performance cams. Are the older engines the better choice? Link to comment Share on other sites More sharing options...
R2D2 Posted May 22, 2001 Share Posted May 22, 2001 I think that the new Mondeo has a 2 litre "Duratech" engine which is all alloy. How long before they end up in breakers yards? Does anyone know if they are the same inlet/exhaust configuration as the Zetec? Link to comment Share on other sites More sharing options...
cskip Posted May 22, 2001 Share Posted May 22, 2001 Seems like the consensus is to convert from a Ital to a Ford Axle to deal with the increased power output of a Zetec engine. What is involved in coverting? How much does it cost to have the conversion done (professionally or DIY)? Clive. Link to comment Share on other sites More sharing options...
Barry Posted May 22, 2001 Share Posted May 22, 2001 I believe that the Duratec engine is Mazda-based, and has a different bellhousing bolt pattern too. Also, for Caterham owners, the carbs & exhausts are on the wrong sides. However, I understand that Raceline are working on putting one of these engines in a seven, so it may yet be possible.

adey Posted May 23, 2001 Share Posted May 23, 2001 > The interesting thing is that the Zetec lump goes in exactly where the XF lump came out. Interesting ... but is that dependent on the gearbox? And how compatible is the cooling system? And is the overall height the same? (Thinking the unthinkable: xflow to Zetec on my Lotus series IV) Link to comment Share on other sites More sharing options...
I.Mupferit Posted May 23, 2001 Share Posted May 23, 2001 Adey There was a thread on this last week. I think the gist of it was that according to James Whiting the Zetec won't fit under the bonnet of a S4. The existing gearbox will fit the engine however and the cooling system layout is very easy to sort. But would be a shame though to destroy the originality of the Lotus. Why not go for a Roger King X/Flow upgrade instead? Brent Edited by - BRENT CHISWICK on 23 May 2001 14:39:24 Link to comment Share on other sites More sharing options...
