The CAD drawings are downloadable from the L23registry yahoo site.
As it turns out, they were drawn by a bloke who built a 23 in the UK. I'm trying to get hold of him, but have had no luck so far.
It isn't a bad drawing and quite detailed, but all the layers have somehow ended up on the same layer, so it will take a little while to clean it up and make sence of. One delema, I do need to buy a set of chassis drawings to verify the cad ones are accurate and correct! I'd hate to build from the CAD ones, then find the body dosn't fit, or the structure is compromised.
A set of copies of originals (5) is available for $60 US, so it isn't a problem. Another US bloke said he'd sell me his whole file of original drawings for US$2 each. That sounded great, till I realised he had more than 200 drawings and post was another $60US. I believe I won't need all drawings, there are 3 L23s in Ch-Ch, so should be able to have a look.
I'll be using a Tranny from an Audi A4
My engine choices so far in order of preferance are:
4agte 20v hybrid.
The thing that worries me about the 1.8T is it's exotic-ness in NZ. It is an excellent engine and can easily make 300hp with std. internals. My thought was that even if it cost more to repair than a 3sgte, that cost would be offset by the cost of making an adapter for the 3sgte. So even stephens.
I had also considered the 4age 20v as in my Seven. But I figured 'in road trim' with that fibreglass body, it might end up at 650-700kgs. My seven is 600kg and I'd like more straight line performance.
I'd use Sierra rear brakes and hubs, as they use the same Lobro CVs as the Audi transaxle, there might be some other options.
I'd use Triumph frnt uprights as per the original. I have the A arm drawings already so would be easy to set up.
