Old school parts and motors / S3 fb front uprights, complete
« on: July 23, 2014, 07:32:24 AM »

I\'ve got a pair of fb rx7 front uprights going, just need them gone, gotta be worth £40 the pair?



Just scoping interest at present.

Ive got a 1975 mazda FA3ts for potential sale, depending upon interest. Based on a Mazda 1000 chassis, its been fitted with a 13b 4 port engine built by carl at Hayward with streetport ports.It\'s got low comp rotors so may be mildly turbo\'d at a later date.
Its fitted with an Italian Weber 48IDA, Series 3 gearbox with shortened shifter, Rx3 engine crossmember, Racing beat inlet manifold, Arc 2 Capacative discharge Ignition, stainless 2 1/2\'\' exhaust merged to 3\'\', Aluminium radiator with pacet fan, MGB rear axle, series 3 oil cooler, lenso rs5 alloys and wheel adapters.

it\'ll come with some series 3 rx7 front struts, rx2 disks and calipers, plus some stock mazda 1000 disks.

Some pictures:

will get more modern pics up asap.

Interest circa £3200?


Old school Mazda's / mazda FA3ts diffs

Alright guys,

had the little mazda on the road since april now, and am starting to think about rear axle changes - not so much because it needs it, more because the ratio isnt ideal.
Currently running 15\'\' wheels with 185/60s, a 13b extend and 12a s3 rx7 box - im really impressed with how the engine runs and pulls the little chassis along.
I\'m going to free up the exhaust and fettle with the steering and brakes, so i just want to shrpen everything up and give it a more driveable feel - with the current ratio  first seems utterly pointless!

So what are you recommendations for a narrow (48\'\' flange to flange or less) and strong axes? Scimitar 4Ha? ford english seems borderline on strength, but parts are a doddle to get hold of. Volvo looks far too wide.

1st generation RX-7's / anyone got some front struts???? for sale

alright guys,

looking for some complete fb struts (series 3 is probably best) including brakes and disks etc.

anyone out there got some?

Old school Mazda's / new oil cooler install - opinions pls
« on: February 14, 2010, 07:10:32 PM »
guys, for some reason the mazda 1000 thread i started is still locked, i would normally post this there.

Anyway - just fitted up a series 5 oil cooler beneath the radiator on the little 1000 - just wanted to get some opinions on it?


this was the other option - behind the rad - didnt like it because i\'d then need a pusher fan :(

what ya think?

Old school Mazda's / My Missus\'s mazda 1000 FA3TS
« on: December 19, 2009, 07:00:52 PM »
Allright guys

This is my missus\'s car - she bought it about a year ago from a gent in clapham, south london.

Its a 1974 mazda 1000 (CC) FA3TS. This is about 2 inches wider than the original STB 1200 and 1300 models. It came with a piston engine of...suprise suprise....1000cc.

The car is really clean, but needs a tidy - and to get rid of the underseal underneath it!
Pics when we got her -

the engine ran well, but the carb was playing up. electrics played silly buggers too.

So we took the engine out -

and purchased a motor, gearbox, and carb etc from a E_X_I_L_E_R. This was sold as a strong engine, bridgeported and rebuilt within the last 4 years (as the builder had only been in the country 5) and a premium was consequently paid. Bear in mind you can buy 12a NA engines for £50 all day on ebay or elsewhere.

Carl Hayward sourced a rx3 crossmember for me which i hoped would allow us to front mount the engine on stock mounts.

I shot blasted the crossmember, slotted the holes, and it bolted beneath the sway bar mounts on the chassis rails - lovely

you will also notice we ground off the existing piston engine mounts from the banana shapped crossmember to clear the \'little ripper\' of a rotorshed motor.

Trial fitting the engine and gearbox, we soon noticed two things -

1. the sump \'bulge\' fouled heavily on the crossmember.
2. the shifter would be moved around 20cm to the rear.

We decided to first of all, reverse the sump. To do this, we used a 13b oil pickup, which we lengthened by tig welding in a short length of pipe -

to ensure a good seal, it was sealed with liquid metal

Using the gaset, I redrilled the end holes of the sump (at the front and rear of the sump) and welded closed the holes no longer required.

ta daa. reversed sump!

Second off, we shortened the Gear shifter position.

General Technical / Dizzy wiring
« on: May 07, 2007, 12:45:31 PM »
Hi, trying to sort the wiring on the rotary bug. I have converted from EFI to carb and dont want to use the ECU or anything anymore.
So i have a dizzy like the one shown below:

Now it has ignitors and i think each has three connections. How do i wire these up without using the ECU?
something like this OK?

In which case how do i determine which of the connections requires ignition live feed and which requires connecting to the negative side of the coil?

General Technical / can a turbo II water housing fit on a 13b NA?
« on: April 27, 2007, 07:15:54 PM »
the flange is the same but i think the front cover fouls. Has anyone notched either the front cover of the water pump housing to get it to fit?

Reason i ask is because i need one to fit my new electric water pump!



Old school Mazda's / Bridge-tastic Rebuild pics!
« on: March 18, 2007, 08:48:02 PM »
Well, we got a fair way with my rebuild this weekend, but as i invisaged would happen, getting the engine stripped down and built in a day just was not going to happen. Anyway, I thought i\'d share a few piccies with you oldschoolers.......
All of these pics were taken once everything was clean.....apart from the second to last pic ;)

and the rotors.....bear in mind all the apex/corner/spring seals were intact. Make your own assumptions! This motor was rebuilt 10K miles ago...... I wont say by whom.

Next up weve got the cleaned stuff ready to start the build...that never happened.....But gives you an idea of the scale and number of parts in a rotary!

not the famous dellorto....but an upper racing beat manifold and 48 weber DCOE. Any interest?


Old school Mazda's / Big Thanks!

Thanks again


Old school Mazda's / just a reminder guys

Anything Engine/Performance/Tuning related / just a little turbo.....specs
« on: February 10, 2007, 09:18:19 AM »
Hi guys,
Looking at the potential of putting a little turbo on a NA motor as they do quite commonly in the states. Either way, i dont wanna run mega boost, for obvious reasons, and have been offered an Airesearch turbo relatively cheaply. What A/R specs should i look for. In adition to some A/R specs (that im waiting for) It has
50mm air outlet
70mm air intake
2x35mm exhaust inlet
68mm exhaust outlet

Whatcha reckon? what A/Rs should i look for?
