MR2 Cosworth???

[MOG7]

I know i read somewhere a couple years ago before i owned an mr2 that someone one running a Cosworth engine, it just had a list of all the known cars to have a Cosworth conversion....

I'm just wondering did anyone hear or know of this car? Sounds very interesting...

never seen a yb in an mr2, but seen it in loads of other cars, fiesta, e30 bmw, rs turbo etc, was it the yb? or the v6 from the granada?

[supersi]

24V granada/scorpio 2.9l V6 cosworth would be quite interesting, tho maybe a little heavy ? It shifts a 1.8 tonne car pretty quickly. Actually in the process of fitting the granada one (easier to use stock ecu) to a Scimitar GTC, but with a manual box :)

That's meant to be a shocking engine though, in terms of what Ford and Cosworth have put out before isn't it?

I'd not bother with Cossie engine in a '2 - there's far better engines out there (did someone say 5VZ :P )

not really johnny, it was the 2.9 block but with 24v heads instead of the ancient ford 12v units, power went up to around 200 ish from the 150 using the 12v heads, the yb was a pinto block with a 16v head and turbo, so no real difference really

I'll go scroll through my hundreds of mags later to see if i can find anything on it...

i vaguely remember the same thing mog....it was a mk1 if i remember right..

At least they chose to try it in the best chassis then :)

The Jun guys had a yellow tubby drag car with full cossie internals - one of the MR2 Only mags featured it - could it be that?

I remember hearing of a cossie powered MK1 up for sale but it was a good 5 or 6 years ago and never got to see it in the flesh.

Anyone remember the cosworth YB powered mk1 mx5 on ebay a while ago?
Built buy a mazda master technician, think it had a hybrid turbo and 300bhp, that must have been some machine!!

The original cosworth pinto prototype produced 600 bhp, and ford were a little worried it would be to much so they got cossie to limit the power to 210 bhp, as they thought the police and buying public may get in to some serious crashes and legal battles may have started as being to powerfull a car at that time, as they wanted to take on audi with there quatro which had 210 bhp in rallying.

the ford cologne 2.8/2.9 took over from the essex engine 3.0/3.1 which is about 168 bhp, twinturbo versions were about 210bhp, then cosworth put multivalve technology in, but good old ford coupled it to a slush box like the camry because they did not want to take sales away from the sierra at that time,but i have talked to several people in the know that you can get 3 to 4 hundred reliable bhp or go upto 600 but you are in to mega money.

a bloke i talk to about kitcars is putting a 2.9 cosworth into a 7 clone heavy engine yes but hes going full bore big money twin turbo so should shift a bit.

There's a bolt on twin turbo kit for the 2.9 cosworth that produces about 350 bhp, but it wasn't cheap.

You can get a converted MT75 manual box to fit the 2.9 cosworth, that'll easily handle stock powers. IIRC they use the sierra 2.9 4x4 gears, so should be good into the 300+bhp.
