Vovchandr Posted May 29, 2023 Author Share Posted May 29, 2023 Here is a detailed one for the SVT blue one labeled as "Doug" (2nd down on the list) Very similar to the other one posted above Zetec SVT Engine with Jenvey throttle bodies. 176hp at wheels Link to comment Share on other sites More sharing options...
MV8 Posted May 29, 2023 Share Posted May 29, 2023 Completely apples to oranges of course, but it is interesting to compare to a mildy tweaked slant six with a single carb. Very similar hp curve up to 5500 rpm but the torque curve is more like a table around 160 ft lbs. Much heavier engine too (high nickel blocks) though some were aluminum.

pethier Posted July 25 Share Posted July 25 I have a 1991 Caterham 1700 Super Sprint and am wondering how difficult it is to install a 2-litre Zetec engine in place of the original 1700 Super Sprint engine. I friend of mine has a Birkin which came to him with a Zetec. He converted it from the side-draft Webers to Mikuni injection with adaptors. He is now converting the Birkin to all-electric. He has sold me his entire collection of gasoline equipment: Zetec engine, 5-speed transmission, fuel tank, fuel pump, fuel-injection management hardware using MegaSquirt, radiator, the whole ball of wax.

MV8 Posted July 25 Share Posted July 25 . I don't know about tank interchange but you should be able to fit Cat engine mount arms and mounts. A custom driveshaft will probably be necessary for length and to adapt your axle to his trans, with new parts or modifying your old one. Plenty of shops can do that work and balance the shaft. You will need to know the right length. I measure bearing cap center to center instead of overall which can vary with slip yoke. The measurement should be 1/2 inch less than the distance with the slip yoke bottomed into the transmission. Don't assume the tune is good as-is. Hopefully you received the webers too. I may be interested in the birkin bare roller (no batts, controller, or motor) once interest in the electric wains. Link to comment Share on other sites More sharing options...
pethier Posted July 25 Share Posted July 25 My friend sold off the Webers. I of course have Webers on the 1700, but I would rather have injection. There are dyno-tuners in the Twin Cities who know MegaSquirt. Link to comment Share on other sites More sharing options...

From what I have been told the cutout is Zetec specific. This might not be the case with a non-SVT Zetec (I'm not sure to be honest). But others probably know more than me. Worth investigating for sure! Link to comment Share on other sites More sharing options...

Worth investigating for sure! Easy fix. Swap to ITB. If I recall my setup is nowhere near the cutout. 1 Link to comment Share on other sites More sharing options...

Worth investigating for sure! That looks like the fuel-injection intake. The Mikuni setup looks like it occupies similar space as the Weber carbs, so I don't think I have anything that looks like this.

I believe that is the Mikuni setup. I think there is an adaptor for each cylinder and each adaptor in turn carries a Mikuni throttle body. Have I mentioned that I do not yet have any of this hardware at my home shop? It is all still in his shop's loft over his machine shop. He has a full-coverage hoist, so when the time comes, we can place each component in my pickup truck. 1 Link to comment Share on other sites More sharing options...

There's a pretty good write-up of one owners conversion to a Zetec on this site: http://my.voyager.net/~quadrant19/XF-to-Zetec.html I've seen this car in person and went for a ride with the owner at the TOTD and it was done very well.
