Looking Superb Graham, Some nice fab work and good looking bits from M sport too.

As Gary says all it needs now is some coolant and some juice and she's good to go

Keep it up mate.

Matt

ps, love the Subaru, might consider one as an alternative to an ST TDCI Mondy

Re: My Mk1 Fiesta XR2

The scooby is gorgeous to drive. The HID headlamps are a revelation. Managed 50mpg on the first tank & She now has 550miles on the clock and I'm starting to give her the occasional 3500rpm burst. Goes well. 350NM so she should tow well too.

Will be measuring up for the radiator in the Fessie, and making sure I have clearance for the Jenveys. I simply need to extend the existing wiring loom, so not too much work left

Re: My Mk1 Fiesta XR2

Looking at possibility of S/C the engine at the moment. Found these pics of an Omex Rotrex C30 conversion, which looks a possibility with all the space I have around the engine. Damned if I can find an Omex site with details of the conversion though.

You could try Steve P down at Track'n'Road, think they have done a few of those now, I know Steve was always banging on about SC's and its the way forward

Yes he is and this conversion in particular. They love a rotrex down there, and I know loads of others who agree, N/A driveability with turbo power

Re: My Mk1 Fiesta XR2

Jam Sport are offering me a discount on a C30, but I'll try to mock up the installation before parting with any cash. Found this Rotrex site.

To be more competitive in Sports Libre I really need some stonking power. The brakes and chassis are able to cope with another 100bhp, its just whether the IB5/Quaife transmission can cope with 300BHP.

Re: My Mk1 Fiesta XR2

Rally Design Escort pedal box has arrived, so I can set about replacing the existing one (cable clutch) with the replacement (hydraulic clutch). I've been working near Bristol all week, on a customer site, so the car is feeling rather neglected. Though I did get to take the Subaru through Cheddar Gorge on the A39 in the rain, which made me smile

I'm going to get in touch with Altiss regarding the S/C. Rotrex unit is less efficient than a turbo, whereas an Eaton blower would produce far more torque from tickover, and Altiss have a good reputation for one-off fabrication work, so this may be quite a straight forward conversion if I can source the bits without it costing me too much.

Been reading Classic Ford in my time off this week, and the cars in there are a real inspiration. I'm going to have to pull out all the stops to get mine worthy of another magazine article, given the competition.

One question. Where I've small holes left from earlier modifications, ie screw / rivet holes, how best to block these without resorting to unsightly rubber grommets?

You're kidding aren't you, not only is this car of the highest quality build it is and has always been pretty much unique.
I'm sure everyone would read with interest another article featuring the new spec.
I followed this car from when i was putting a zetec into my escort and it was an inspiration.
With the duratec you are still pushing forward and if you do go the s/c route then it is gonna be scary fast

300bhp with the torque from a supercharger not for long would be the answer i'd expect, the quaife gears although straight cut with bigger stronger teeth are only the same width as std, from memary quaife quote the max recomended power for thes boxes as being 175BHP

Re: My Mk1 Fiesta XR2



So crunch time. DO I cut the front out like this (above) to clear the throttle bodies (zero cost, but what does it do to the looks and rigidity of the car?)

Or do I get the inlet manifold modified to run the throttle bodies at 90 degrees to the block, so that they are lowered and run straight out through the grill? Altiss would do this for around £140

Or do I get some direct to head throttle bodies, which shortens the overall length, and again, points the trumpets lower down at the grill. (expensive)

Or alternatively, get some roller barrels, but again, this aint a cheap solution.

[david_white]

Re: My Mk1 Fiesta XR2

IMHO I wouldn't go the route as shown in the picture, the manifold looks very steep which won't help power possibly and as you say virtually all the strength is gone meaning the engine will take the brunt of any frontender

Sounds like the best option is to get the manifold staightened out so you can use the grille apature without cutting the car up. Hopefully the straighter manifold will give a better airflow too

Re: My Mk1 Fiesta XR2

Thats the Puma engine in that picture.
This is how mine looks with the Jenvey inlet manifold and twin TB's

I could always go the Cosworth roller barrel route... but only if I knew the overall length of the cosworth setup with their airbox and the 100mm trumpets in place.

Re: My Mk1 Fiesta XR2

Graham Icky has got the cosworth roller barrels on his escort i am sure he could measure them for you ,try pm,ing him or kev mk2 they are both top fellas car looksby the way

[team_zi]

Re: My Mk1 Fiesta XR2

Thanks Toymex. PM sent.
I can always sell my Jenveys and inlet manifold to offset the costs, as the Cossie barrels aint exactly cheap.
