ahem, and where did the nissan A series engine design ultimately come from?? yes you're right it was from the BMC B series via the early nissan E engine.

There a mini out there with a BMW 16 valve motorbike head on it producing 170hp without the help of forced induction so dont go bashing the brits! Bet theres not one part on a japanese car that fits every model japanese car! the chances of that are more probable with a brit car as they never changed anything

interesting, thats probably quite a common head. Ill keep that in mind for a future a15 build. I hate doing the normal basic mods - id rather try something new or uncommon. I guess if i found a running a15 which i could mess around with a DOHC head and get that running then go do the full hog rebuild and find some more horses inside the old lump. Theres something about the a-series engine that makes me prefer them to more modern designs, maybe its the challenge of getting the most out of a basic economy focused engine.

any DOHC heads that fit better than the mazda?

anyone ever considered doing this?

mazda b6 DOHC head, distributor less ignition, fuel injection as factory on head and a well chosen turbo on the side.

Why not combine all the wacky conversions (EFI, turbo and DOHC) into one engine.

Ive got a 4-wire nippon denso wide band sensor on the a15e ive built. Havnt run it yet though so cant give any other information. I dont have a gauge but the computer will let me know whats happening when its connected to the laptop

Progress...... but slowly. Things like different temperature senders for coolant, headers, oxygen sensor nuts falling off headers and that sorta crap has slowed me down a little.

On the to-do list before i can fire it up i have:
~ run power cable to fuel pump and earth pump
~ seal tank
~ run flexi tubes between pump and steel lines
~ run power cables to each of the two relays
~ wire the intake air temperature sensor
~ sort out what is + and - for coil (mitsubishi unit that came with the manifold)
~ fit radiator and bracket
~ put nuts on the engine mounts


Oh and some engine oil!

heres a pic of the current state:



doesnt look different from before but a fair bit has changed

i shudder at the thought of someone now knowing they have a competition head and throwing it out for $10 of scrap alloy.

once they are gone they are gone. On that topic, are the castings for a series heads still around? perhaps if they arent selling them anymore then the castings could be up for sale at the right price to the right person.

nup, dont need to. There is room because the throttle body sits above the chassis cross member and there is enough room to get a 90° fitting on it too.

some more work done today - got the manifold bolted up properly now and some of the wiring done but still a lot of work there to do.

update time.

I put the engine and box in today. Went in smoothly and easily. I have a small problem though, i need to modify my adapter plate again for the manifold as it doesnt clear the header's flanges.

Anyway, i sat the manifold in place for the photo:
