RX3 PP

No just a 3b main ports just cleaned up, full length bridge on secondary's. Just been for a drive, it drives like a standard engine, just beautiful. I call a 3b port big as that's all you need for a n/a engine.

Thought I better get a move on today, had a wee bit to do, fitted the alternator back on with a new pulley as wanted to get rid of the shitty Gilmore drives, they may look and sound nice to some, but they do suck a bit of hp as I found out with different engine builds over the years. Next step was to get a belt after a couple of visits to repco finally got one the right size. Bolted up the starter motor and fitted back on the exhaust, crossing fingers there's no leaks, engine oil is in, water in, dizzy connected up. Just for good measure I'm charging the battery overnight, as need to crank it over without the plugs to clean all the Vaseline and crap out as well as get all the oil circulating through the galleries before we add some spark, after 40 odd seconds of cranking oil pressure gauge will come up, well that's the plan. I've just got the carburettor left to bolt on. Brian's giving the original rx3 carburettor a complete rebuild and has modified it as much as needed to feed the big secondary jport. I'll take a video of it once running although not sure I can post it in these forums.

Apparently yes

So finally I have got the engine out of the van, needing a lift as I'm still waiting on an op to get a kidney stone and a stent removed, and although as sore as hell and pissing blood, I just gotta get it done, she went it pretty sweet, took about an hour and most of the gearbox bolts are in and the front mount is secured, water pump and impeller fitted, radiator hoses on. Leaving the rest for another day. To sore to continue but got what I wanted to achieve done.

Ok so I've found out a bit more about the NZ new savanna, my mate has spoken to his old car painter who did a touch up on it years ago. The painter said If definitely had the square tail lights like the aus version and also on the rear passenger window had a GT badge, so this sounds more like what It should be like

I built it from scratch was in chch then went to auckland as far as I know.

Spoke to to the man whom brought it from brand new, was registered as "1975 savanna rx3 coupe" the rear quarter badges weren't the only thing applied, there were other differences as mounting of the fuel pump, fuel tank cover, etc. it may be similar to a lot of other rx3's. Maybe as so little came to NZ, no one knows much about them.

Engine is now complete, with original rx3 engine parts, hopefully might get time at the weekend to put the engine back in, only real concern is hoping its really drivable as i still have probably around a 9 lb flywheel so we will see. Will be far better than a full j or pp regardless.

Time to put the new engine together

So there it is ready to go together, rotors are now assembled, hoping to get time on Monday to assemble engine, I have the exhaust ports raised only to a certain height, mainly to keep the peak power lower in the rev range, also the 3B inlet ports are kept stock as if you start going much higher it will start to compromise the engines power, running a full length bridge on the front and rear plates. N/A engines are critical with port size so this is where my ports will stay, turbo on the other hand can handle a far bigger port. I may in the future look at bridging the primary's but this will fly with the rx3 carb modified correctly with manual secondary's and also the correct exhaust, in which my case, my current exhaust is completely wrong, so there's another grand gone! Keeping a tally I've spent about 25k to date, but then sometimes it's probably not a good thing to think about.

It's in auckland now, and has different mags as shown below

Yeah all very similar stuff and colours, and I guess being all mazda a lot of stuff could well be generic across some cars, front seats look very close, trims and back seat look different but similar, never had anything to do with 323. I become a rotor head at age of 20, to many years ago to remember it all, I do miss my old rx2 sedan tho

I've also got exact original factory carpets which I'm going to get new carpet copied exact to look mint, so if your after a pattern of it I'm happy to give this to you.

I even have the original fuel tank shield that could be very easily copied, also theirs a trim that sits in the boot that's a follow on from the interior door trims

Well if your ever in chch you can view if you wish to copy them or I can send pics as I know mine are definitely factory spec. I met a guy on fb just a couple days back who had tan trim also, it was a savanna also.
