how many versions of this engine are they?
What are the standard engine outputs?
Since the engine was based on the Taunus/Cologne Engine Can a 2300 base model engine(from the cortina etc) be used to make a 2300 24v?
Have a damaged 2.9 24v n good 2300 engine.
thanks.

the 2.3 engine had a smaller bore than the 2.8/2.9 on which the 24v is based so it may not be possible because the combustion chambers might end up overhanging the bores, and i suspect the loss of 600cc would result in a very low compression
2 Versions of the 24v. BOA and BOB. BOA in the earlier Granada Cosworths, and BOB in the later Ultima/Scorpio Cosworths - Thicker block, different cams/plenum/ECU.
BOA approx 195bhp stock. More if you De-cat, and swap for a better ECU it seems. Lots of benefits to fitting BOB cams if you can get them. Easier to fit/setup than BOB engine due to being EECIV.
BOB approx 205 - 210 stock. Harder to tune, but probably getting more available now. If it were me, i'd get one, bin all the EEC etc, and stick on a mappable ECU and wire it up to that properly.

lots of differences in the block between the old colognes and the 24v so a 2.3 conversion would be difficult, not to say its impossible as a few guys are building 4 litre versions using the american Explorer block (i've seen ohc and ohv versions being used) its not a bolt on job though, plenty of machining needed and things like the dizzy drive goes the wrong way round to work the oil pump etc etc.
There are loads of differences between the 12v and 24v blocks, there was a previous post covering it here http://www.turbosport.co.uk/showthread.php?t=97643
The manual pictured is for a BOA engine
