If people want to have a crack at this NA a15 stuff - count me in. I've been working round the clock in the last 6 months (new job, love it) and slowly stockpiling parts for the supercharged a15 buildup.
however - I picked up 2 a15s from 'clubman' (I won't use his name here without his ok) who used to have them powering his racer. He's moved on to sr16 power (and power it has aplenty for what would be a close to stock setup, with tweaks to induction and exhaust mainly, but stock internals)
Anyway - amongst the bits are a heavily ported oval port head. It's been shaved for higher compression, so probably won't go on my supercharged setup. I'm happy for someone to use this as a test bed head or whatever. Maybe we can all bring enough ingredients to make decent soup, so to speak.
I think I can also get a std bore a15 block (but just the block and caps) - it's from an a15 I sold some time back, but the buyer used the internals in an a14 block based combo. He's indicated he'd be willing to part with it for a price to be determined, so I'm planning to grab it, whenever I can find the time to catch up with him and seal the deal.
I've also gotten a cam approximately the same (varies by a couple of thou lift and a couple of degrees, so likely within a couple of kw) as the 140 profile on this page
http://tighecams.com.au/profiles3/nissana12.htm(but I must stress it is not from tighe cams, just happened to be a convenient online link that happened to have almost identical profile)
I suspect it might be a touch too mild for this build, but it probably isn't ridiculously out of the running.
I don't have any webers or twin weber intake manifold, but I can lend a set of 4 into 1 headers, that would be close to ideal primary diameter for this project (and possibly just a bit shorter than ideal primary length, but again, not out of the running, and primary diameter is far more critical than length)
There's a set of FCR carbs I'm buying from D (if i can ever arrange a time to actually catch up with him, pay the money and grab em!)
What else - I dunno - a flywheel or two and other bits and pieces, if needed. Going by how busy work currently is, i can loan these parts out for a considerable period of time.
