Rob has built an early A12 using the early
Mazda B1 and B3 engine with 71mm bores

https://en.wikipedia.org/wiki/Mazda_B_engine#B1

Robs 8v A12 was to be fitted to a 1000 someday

B1 & B3s see 8-9k rpm @ speedway / circle track

Yes, there is no step-by-step guide. However there are partial guides such as post 61 in this thread.

Quote:The "a15 block mazda head" is referring to the Mazda 1300 DOHC head, which has valves too big for the A12. And if I understood correctly, requires the DOHC pistons (see post 61) which won't work in an A12.

However...
Quote:So the SOHC head will fit on A14. And you can bore an A12 out to A14 bore size and fit the A14 pistons in the A12. So the SOHC might work on an A12.

DOHC vs SOHC

This is kind of a figure it out for yourself in a way.

I am going off pictures mostly. I haven't seen a list of what to look for or things to avoid.

Search out some of the Mini Cooper forums. Those have had some how to threads with great details about this build.

EDIT ..

Has this been done on a A12? Can it be done?
Whats neded?
Could someone guide me to what I need, and what to do? :)

Im reading/have read, the "how to" that is in this thread, but how does it compare to a A12 when it's a A15 in focus?

hi at this stage all the kits have been sold. will not be making any more at this time. sold them to some morris minor owners with a 14s in them. using single cam 8valve cheers rob

Hello, I am interested in this kit. Please email or PM me specifics, parts, price, method of payment, how to, etc... Thanks, this is probably going on a A15 1981 Nissan/Datsun 210.
Also, where to get headers and side drafts carbs for this kit that will fit on the 210?

I have shifted gears and I will be putting a GA16DE head on my (A) block instead of the Mazda head.

Anyone want to purchase my Mazda head :D

I was halfway thru getting this all together, when a cash flow incident stopped progress.

As soon as i have an update, ill post some info.

Rob, the evil mastermind behind it all has had this setup running reliably in a 120Y

Has anyone got this setup running reliably yet with some dyno results or maybe a video of the performance?

Are you located in melbourne, Can i have picture to the mods on the A-series block
