EBXR

With the Aussie Mk2 Escorts, all 2 litre's (Includes RS200's, rally packs, etc) had the 3.54 ratio. 1.6 litre escorts had the 3.77 ratio. Some panelvans had the 4.11. The gearboxes were the same, the RS just had a quickshift.

In the UK, a 2 litre escort was the RS2000. The gun machine was the German RS, which have a few differences to the Aussie RS.

Yeah, the German RS's had the EB engine, which my car shares the same block. In Oz, when they ran out of the normal blocks they imported the German EB ones until the supplier caught up. Unfortunately they didn't import the better heads as well.

I still read that the RS's had a shorter diff ratio but you can't beleive all you read I guess.

Reading in an engine buildup book for the RS2000, its peak power was around 5500rpm for info, not sure how much diff the standard 2 litre would be, if at all.

whats this EB block,I havent heard of it before,to my knowledge there are block casts,200 rs500/202 race spec/205 cosworth blocks, then the standard blocks.
Why are the EBs different I will have to look into this,is it the hole bottom end or just the block you have.
All aus RSs are 3.54 rear endpretty bland ratio for a so called performance rally car,Mine s got a 3.89 and 5 speed to liven things a little

thanx for all the info guys!

lol funny stuff, selling the xr, dont let them falcon boys hear bout that lol

btw i bought this eski with a 3,97 diff, sitting on 60 you couldnt even drop back a gear, as soon as you did, it would "redline" at about 4500rpm.
but lucky i changed it back to the 3.54 diff

hey anyone know whats a good lsd that will fit in the back there???

hmmm eskis reving to 7000rpm aye? guess you have to do some head work to get that huh?

I don't know a whole deal about it yet, I'm still learning a great deal from the previous owner. He races Escorts in Group C racing, apprently they are stronger for high performance engine buildups and he wanted to keep the engine for racing, but sold it to keep factory numbers with the chassis.

I'll email him about it specifically to find out a bit more about it, but the Oz cars that got this didnt get the german heads which gave it the extra HP over the std engines.

Still new at this Escort game, sorry I don't know it all yet, getting it all together bit by bit.

Er, not that I know of, the tacho just says 7 grand with no red line there and the engine happily winds out there. The car only has the 40mm Weber, extractors, exhaust, and a cam fitted, but thats all I know about. I didn't hang around it alot, hell, anything over 4 grand was a rush to be honest, most times I was changing at 5 and a half or 6 when i was giving it a go, otherwise it was lucky to see over 4 grand for just touring around.

Dunno about an LSD that will fit up the back of an escort without modification, but if you find out or anybody else knows, I would be very interested!

Yeah, just like Tim, my Eski will rev out to 7000rpm without a problem, it's not somehting I do regularly, nor do I keep it revving that high for more then a second or two, but it has no problems getting that high in the rev range.

Probably not that much point revving it that hard without some headwork and exhaust mods (probably cam and carby too) - at 7000rpm there isn't much time for the exhaust gases to be expelled, nor is there much time for the air/fuel mix to be sucked into the cylinders, and I'd be very suprised if a stock pinto 2.0 is able to breath well enough at those sort of revs to make it worth revving her that hard, but geeze they sound angry (in a good way) above about 3500rpm, don't they?

There is an english motorsport LSD available but the centre alone is around $1200 and parts are hard to find,its much cheaper to modify hilux /hiace diffs as there is quit a range of ratios and lsd are available cheaply.
I will be going down this road next year

yeah mine used too(still does but not as much atm) but now i got a sound like marraccas when i drive, and the bl**dy exhaust got a hole somewhere cause it used to ahve a mean as sound coming from the back, now it sound really sick like, so i haev to take it back to get it fixed(thank god for warrantys :D )

man, now i know why ppl dont often buy cars for complete resto's lol nothing but constant headaches lol but it will be all that much better when ive finished it *enter drool emoticon*

Back in the 70's when the Cosworth YB was but an itch in Keith Duckworths crotch, you basically had the normal 2L blocks or the German (read European) blocks. They are very similar but had slightly different main caps with a bit more meat around the bolts. They're called "EB" blocks because they have the letters EB cast into the block on the exhaust side between cylinders 3 & 4. A full German bottom end also has a slightly different crank and "selected" rods - whatever that mean't.

When Ford Australia ran out of local blocks they used to import batches of them to keep local production going. Generally these engines are just EB blocks only, but you never know. Then you get German heads, which have the letters EB cast into the valley on the exhaust side between cylinders 1 & 2. For some reason motorsport in the 70's & 80's used to chase down these blocks, but in reality the differences would only show up after many hours of racing or in big HP turbo motors. Hence the 200 et al blocks of the 80's & 90's. Over about 400hp the older blocks suffer badly from distortion on the cylinder walls.

So now you now all about EB blocks.
