Found out this weekend the later half of the production of first gen Focus came with the Duratec instead of the Zetec. I got the SVT classed in FP and that is great. Was talking to an STL racer that is running one of these later cars and I'm trying to get him over into Prod. Anyways. The cars are the same as all of the first gen Foci, power is a bit lower than the SVT, they come with smaller brakes and some smaller tires. Is there a way to get SCCA to allow the SVT Focus and the Regular Duratech Focus to interchange engines and basically just cover the Focus as one car with two motors?

Power wise they should be the same when built to the rules, but the nice thing is the Duratec engine carried on almost another 10 years, where the SVT engine went away when the Duratec came along. The thought was classify all of the Focus platforms from 1998-2007 as SVT spec with either engine option. That would allow the racer to pick the Duratec or the Zetec engine for any of the cars. The transmissions are the same, the chassis is the same, just some cosmetic differences that don't really apply to the race cars.

I sent the VTS to the owner so he could fill out the paper work on the basic 06 Focus he is running. In theory, he would run lighter than the SVT due to the tiny stock brakes and small wheels. Instead just classify all Foci at the same weight as the SVT and other specs, just allowing the two engines to interchange. Performance wise he could be same powerwise as the Zetec in STL trim and thus be competitive with the rest of the FP field.

Wonder if he could get Mazda contingency for running a Mazda engine. LOL

Zetec in the Chaterham is a EP car. I believe it is restricted too.

Run what you have first and it will be evaluated.

I’d like the Lotus Twin Cam Motor in my Lotus 7 too.

The Zetec in a Caterham is an entirely different animal than the Zetec in a 2500lb FWD strut car.

Just wondering if this type of thing has been done for other cars. Allowing different engines for the same car.

not familiar with other cars where it's allowed, but the RX7 can use the 12A or 13B with appropriate weights and whatnot.

It is also allowed in the mk1 VW's. There's about 10 different motor configurations for the same chassis. Just different weights, TB size, Brakes etc. between them. Great parody between them from what I can tell.

The MG Midget / AH Sprite / Bugeye is a great example. I believe they can even mix and match body shapes.

No longer a vin requirement for cars so if the body is the same go for it.
