Sure, but it doesn't have a green area that goes from 4-6 bar....

So it is :( still, 600hp from a 2.1l should need around 3-4 bar.

Pikes peak anyone?

I'd be cautious. Rare and valuable car for sure but how can we really know he speaks the truth about the 600hp part?

I always wanted an RS200 but got the XR as the poor man's substitute. I always found it funny how many XR parts are on the RS200 anyway... like the entire door assemblies.

BTW, here's the GRMer's approach to getting an RS200 if anyone is interested... c/o MC2Racing's Grayson: http://www.mc2racing.com/tech/EVO200Build.pdf

Back in the day when ford couldn't give the last few away, my dad got an invitation for a test drive in one - with a driving coach - the thing was he had to go to Scotland so Jackie Stewart could show him around a track. Believe me - I begged for him to at least go for the drive and of course take me with as an advisor. He didn't bite. Asking price then was in the $80k range for a road model.

I kept the invitation for a few years. I think the worst part of it all was that at the time he had a flat in London and tons of airline credits/miles. If it was golfing with Jackie Stewart, he would have been on the plane.

I was thinking on how to make one of those replicas AWD. You could take the 2.3 Mazda turbo engine, mount it the correct way (like the Cossie) and use any type of Independant Front & Rear suspension you wanted under the front and rear. Use the stock transaxle and run torque tubes to the front and rear diffs.

I saw them do something like this on Xtreme 4x4. They built a little buggy with a Honda 4 banger like this.

Yeah, but you'd need 1:1 front and rear differentials. Not exactly common to find.

You could order custom gear sets for common axles right?

I don't know if the size of the actual ring and pinion needed for a 1:1 ratio would fit in a normal automotive differential case. The pinion would be huge or the ring would be teeny-tiny to get the one for one rotation.

If the Ford Escape has a 1:1 rear diff like someone suggested it might, that would be the key to recreating it.

I work at a Ford dealership... Lemme find out...

OK, doesn't look like that's the case. I know the Xtreme 4x4 buggy has geared front and rear axles, but I'm sure that's just because it's going to be a low speed crawler. What about some other vehicles with this type of configuration like the GSX Eclipse or AWD Audi's or something?

OK, just brainstormed with my transmission/driveline tech. Here's what we figured out...

Find something with am extremely high final drive gear. Something in the 2.20 - 2.30:1 range. Then find a pair of axles with the same type of crazy high gearing in the low 2.watever:1 range. Put them together and you now have a 4.something - 5.something final drive ratio.

2.23 transaxle final drive + 2.30 front & rear axle ratios = 4.53:1 final drive ratio

Now you can correct with larger wheel diameter and you're on your way!

So where would you find a transaxel with a final drive in the mid or low 2s and will it mate to any worth while engines? I've been wanting to build something like this since I was a teenager, but have never figured out a workable final drive. A transaxel with a final drive in the 2s with F/R diffs with gears in the 2s actually sounds smarter. Instead of taller tires, how about a high revving engine? Does the 13b fit any Fwd trans?

Hahaha! Well, I know that there are tons of aftermarket gear ratios available for the Honda drivetrains. I'll look a little more...

I think I posted a perfectly reasonable way to do this earlier in the thread.

Audi Quattro transaxle combined with a 4WD PTO style solution to turn the rear drive output to the front.

The transaxle is plenty strong.

RE turboswede: Thats a not a mid engine, all wheel drive setup if I'm understanding you correctly.

I re-read your previous comment: You're 'custom PTO' is the deal breaker in terms of being GRM. In my eyes the custom PTO is a magical device. Yes I know it is perfectly capable of being produced with regards to engineering and manufacturing but you can't walk into a junk yard to find one . If you'd go through the process of making a 180° PTO box, you'd be able to make a bespoke transaxle capable of the original.

Ross, you beat me to it on the Audi transaxel problem. In addition to the unobtanium of the 180* pto it would also require a very long drive shaft, from the tail end of the trans and back up to the front of the car.

I do, however, know of a way to make a semi-grassroots 180*pto, thanks to an episode of Monster Garage. When they built the 4×4 corvette mud racer, they made a single speed transfer case from chains & shaft mounted sprockets in an unsealed welded steel box. That probably wouldn't be tough to duplicate and even improve, but I can't see it working out well for rally car duty.

Sigh....

like custom 1:1 differentials are a obtainable item?

http://www.awdwiki.com/images/audi-quattro-I_x.jpg

Adapt a transfer case from a 4WD/AWD vehicle.

Long driveshaft? Is another 2 feet is going make a huge difference? Especially when the front diff will be fixed in place.

BTW, the RS200 isn't that large.
