I'll email them to you so you can get started straight away. 
I got them Rorty. They are exactly what the Doc ordered.
Here is a pair of 3Ds Max renders showing how they might work in my car. (as an example) You can see the outline of a 4AGE back there too as a
comparison.
Opposing with center jackshaft -
Inline with rear jackshaft -
Edit - I meant to say that BEC definitely requires more room than the Transverse Car package!

Useful stuff
There's a couple of good resources for this stuff
First off is Z-Cars http://www.zcars.org.uk/. Chris Allanson has been building twin grass track racers for
yonks, and is also responsible for the twin engined tigers / and a number of westfields like the Tim's at
http://www.just-the-one.net/. Take a look at their Twin-engined BEC RWD Mini - this is a working
solution to your problem.
Secondly is the BEC group on Yahoo! This discussion has been had several times there, with a number of novel solutions / suggestions.

Right now it's temptation tempered with a lot of research. The current plan for the 4AGE with turbo is still the #1 project.

My back is much better now and I am doing the car thing full-swing again. Happy me.
I have visited both those websites several times. Nothing much mentioned about synchronization issues between the engines.
What do those in the "know" think about these gears? They are found in a mid-80's Chrysler transmission.
They are splined internally.

First impression is that they look quite large. They may be needlessly too large. Being helical gears, they will require substsntial bearings (hence
the taper roller bearings) and bearing support to resist the sideways thrust. They will run quieter than straight cut gears though, but I really
don't know if that would be a problem, as the bike engines' boxes are all straight cut and you're talking about running two of them
with twice the engine and exhaust noise.
I would be inclined to look at bike boxes for light weight, strong, splined gears. Some bike shafts could also be useful.
A good source of cheap, off-the-shelf splined shafts and gears is your local industrial supplier. You can buy 4 and 6 splined shafting and matching
gears. They should also have just about every imaginable accessory for a driveline, including matching splined UJs, blank or "weld"
splined hubs and internally splined bearings etc.
For one-offs and mockups, they are a valuable resource.
Most gear supply outfits also stock standard items which may be useful and fairly cheap.
Once you have a satisfactory set-up, you could then look at refining it and possibly have some custom parts machined.
I've used off-the-shelf stuff for several projects simply because I can pick what I need out of a catalogue.
You'd be surprised who uses the same stuff in high-end drives and machinery.
A quick look on Google brought this lot up from your side of the pond: Arrow Gear.

looking at my HPC gear catalogue, the gears i think would be most suited are about 17 quid each! is that a normal price?
thats for a heavy duty gear, 25mm wide, 30 teeth, 60mm PCD and a 20mm bore. £17.78 each. YG2-30 on page 472, if anyone is interested and has a
copy.
any thoughts on this cog? is it overkill? underkill? right material?
