2.9 from an S any use?
Discussion
It looks as though I may be getting my hands on a 2.9 lump from an S. There are no heads or plenum wit it, but everything else is there.
Questions is will it be of any use to me being as I have a 2.8 in my Wedge?
Are the blocks/crank/pistons/rods/etc the same? Where does the extra 0.1 litres come from? I heard you can sroke a std 2.8 to 2.9 putting in a later Granada crank. I'm assuming this is the crank in the S...that would mean the block and pistons would be interchangeable?
Any ideas? Depending on what can be done with the engine I'm thinking either build up a nice, strong engine and keep it handy for when the one in the car gets tired or strip it for any useful parts and make a coffee table from the block

pretty much a non starter this unless you have machining facilities or can get it done.
the crank noses are different, the 2.8 cam is gear drive the 2.9 is chain.
the 2.8 heads are 5 port, the 2.9 are six port.
If you want the extra urge then why not just rebuild yuor 2.8 for more go, or subsitute a complete 2.9 engine instead. trying to make a hybrid is much more difficult.

Well...I'm not really looking for more power (though that would be nice
). The engine belongs to WildfireS3, he bought it for the heads and plenum and it's now sitting in Minimax's garage. He's moving back down south in a week or so and doesn't want to lug it all the way down there so he offered it to me. I'm not one to turn down oil playthings to fill my already overcrowded flat. I was just thinking it would fun to strip and rebuild it. And in the process end up with something that may come into use in the future.
I think if I was going to go for a full swap I'd go the extra mile and get the 24v Cosworth.

Hi Joospeed,
I'm also looking to do a similar thing and am curious what the problems realy are. I'm aware of the differences you point out but why can't I bolt the 2.9 heads onto my 2.8 ? The blocks are essentially identical and so I know the heads will fit. Clearly I will need to use the 2.9 headers but as I understand it, the inlets are in the same place. Are the valves arranged in a different order or something ?
Took the standard 2.8 out of the Tasmin race car (car 13) at the beginning of the season and replaced it with a 2.9 lump. To get 240bhp I took the engine to John Toovey in Cannock who put in a steel crank & rods, beefed up the whole installation, removed the injection system & fitted a Webber carb. The engine was stroked to 2997cc and you could rev it to 7250rpm. You did however have to be careful not to miss a gear whilst changing down in case you 'bounced' a cylinder and damaged a rocker.
The car was incredibly quick and in the wet on the windey bits, was faster than the Tuscans! :muchmuchbetterthansexohyes:
You have to have new manifolds made and will have to move the alternator over to the other side. You will also have to look carefully where the bottom hose comes out, as the new installation leaves you very cramped.
Great fun though!
You can get an exchange unit from Toovey from £2500 including carb & dyno bench, and the manifolds and everything else cost me about £1000.
On the track it really was awesome - watch out for Jes Bunce running it next season in the challenge - he's testing already.
As far as road car economics go - you might just be better to trade in the wedge for a quicker one... worth looking at though.

Spotted this on www.passionford.com if anyone is interested. Seems like you'll get nearly everything you need for £250 but then I guess the exhaust will cost you 3 times that to have made. In my view still a cheap conversion.

I think having a standard 2.9 installed would be as involved as the 24v unit. The engine itself would bolt straight in (and yes, the bonnet does close ok) but the manifolds and a wiring loom would cost. JW Eng (advertise in sprint) can rebuild a 2.8 and modify extensively. Btw the extra 100cc comes from the longer throw crank, again JW can retro fit this.
I seriously doubt that there is any benefit to having a 12v 2.9 fitted, very little power output difference and lots of electrics involved.
the 24v engine is a different beast altogether, admittedly i only have the granada with this engine but i own a series 1 tas, and have had a 12v 2.9 granada so can compare the engine's characteristics first hand.
Your car looks like a series 1.5 so could have either the 4 or 5 speed box in it but from my experience:
tas with a 4 speed box is a great combination, only flaw being a flat spot in the powerband when changing up gears.
2.9 12v pretty much the same with a less noticeable flat spot.
24v 2.9 has less go below 3k rpm but then goes like stink more bhp than a standard 350i but without the (very) wide power band.
