I would be onto it Big D, well if the lawyers would at least kiss me before they rape me, but it might be better they are doing it rather than "Her" doing it...

OK fellas there are new batch available 

PM me for orders or for deposits for these beautiesAs Datman1947 has cut the time it takes to finish them up [size= xx-large]new batch ones at 790aud[/size]This kit is all you need to get it all sorted a bargain for a twin cammer A series
No more waiting for an AY or billet twin cam head just get a B6 head from any Mazda,
Ford and Kia for a bargain price and mod your block as described earlier.
I will supply all the details in printed form for reference to make it happen.[size= large]This is an amazing opportunity that has more hp and less cost than a worked GX.

Block needs pushrod holes drilled and tapped for brass plugs or any steel plugs will to (short countersunk hex bolts will do will put pics up soon) and oil drain holes next to pushrod holes also plugs the same way using three smaller countersunk plugs or easier with devcon type filler. Front water galleries same thing and some water galleries opened up just a tad.
 
The oil feed of the side at the top plug side in the middle drill out the brass insert to use as oil feeder to the head. Tap the same feeder at the top of the block to block it, and run line brass line to the head  oil feeder which is easily drilled and tap where pics will show.
 
Will put pics up, theres no welding anywhere very easily all done at home even the brass drain plugs from the head are easier than his first versions which he used welding. Its all sorted now after further development he has an easy setup.

Early A12 no problems but will need 76mm bores as minimum or 75 flat tops and notch the bores to clear the outer edges of the inlet valves like some A series do for big valve heads.
 
Im personally doing a 1mm oversize mx5 piston for 79mm and sleeves and A14 crank into an early A12.

Ohhh bloody hell... Ive been mega busy away from the forums for the last few months and this turns up!!!

I need a job before I start spending too much cash on cool porn like this.

Im hoping that this wont be a one off thing as Im off to do some more research before I wade neck deep in, but I am still very interested.

I recently took delivery of this setup from the seller. Despite what seems like a high price, it is in fact very good value.
 
It looks great, and he is mega helpful. I have assured him that I will be taking photos and documenting this as much as  is possible, with the intent to create an instruction manual as such.
 
AS I track through this project, which is hopfully starting shortly (cash dependant) ill throw up some pics, in my project thread.
 
 

That would be awesome reubs, I should have one of these kits soon hopefully. Im just going to go high comp efi itbs me thinks and maybe stuff around with boost after

Yea boost is fast but cost the $$$$ that I don't feel like spending lol

What sort of fuel are they running d?

Ive got a 77mm a15 block that needs a home. I was under the impression that i need 78mm to clear valves etc.
 
But above you have 76mm is safe. 76mm is std A15 bore so thats a win right there. Any a15 block is good to go.
