Martin,
Why not pop over to see me,I might have a pick up that will do the job.
Regards
Carl

Ok Carl, thats actually a good idea.

We could look at my FD cooling system at the same time !

NO !:guinness

Hi Carl (your email in your advert above is bouncing)

There might be an opportunity for me to pop down on Tuesday to see you.

I would be interested in an oil-pickup - I will bring my sump cover with as it has an adapter in it, I think for oil to return from a turbo.

Could we also test my cooling system on the FD?

What time do you open?, I will endeavour to be there as early as possible.

Well, I took my sump and pick-up to Carl back in Feb, and he had a look and confirmed that he doesnt have and RX-4 pickup lying around.
So I left it with him so he can try and make me something.

Yesterday fitted the pulley and I have painted the timing marks bright white so I dont lose them again, and to help me set the timing ( If i ever get as far as trying to start it !)

Quote from: RayHi Martin,

RX-4 does have a centre bearing, RX-3 does not, however we\'ve used both centre bearing and single piece props on the race RX-3 with no noticeable difference. The way I\'d go about it is to get the engine and box in first and see what gap is left, then tape measure in hand check other mazda\'s to see if one from a scrapyard might fit, possibly RWD 626. If that fails you can get one made up for not too much, if you supply both UJ ends of the propshaft and ask them to make to a particular length, it should be trivial for a specialist company. Thinking about it series 1 and 2 RX-7 should have the correct ends, but I\'m guessing it will be too short.

The RX-7 gearbox shifter can be mover forward about 3 to 4 inches by cutting the selector rod and remounting, difficult to describe in words, probably easier to give me a ring with a gearbox in front of you and I\'ll explain. Alternatively, I\'ve got a 4 speed RX-4 gearbox which would drop straight in, depends how much you want your overdrive.

Good luck :3gears-rh

Hi Ray
I am at the stage where I need to do this piece now. If I can do your mod for the gear lever, then I dont need to mod the prop shaft, and I can keep the centre bearing.
How do I get your number, Ray, I cant send you a PM. Perhaps email me your number at martinyates@ukf.net

Thanks!

Hey Martin, hows this comming along? Its an awsome project :chat

Martiny · April 22, 2007, 09:26:41 PM

Hey the project has been stuck for ages, but its getting going again now !

Martiny · May 08, 2007, 11:21:32 AM

Gearbox housing modified, the prop shaft sits nearly straight coming out the gearbox. Have nearly finished making the gearbox mounting. The original mounting points are about 30 mm out of line, so the gearbox is sitting a bit forward, but the oil filler neck is more or less lined up with the shock towers, and I think that is correct. Anyway, where it sits now means I can use my existing prop shaft, without modifying it.

So gearbox, engine, and prop shaft are temporarliy lined up in their postions. I have started making the engine mountings. I have made some plates that fit the shape of the cross-member. (currently only tacked onto cross-member.) Then the rubber mounts go on that, and then the front mount bar from RX-7 will connect to the rubbers. .

So, now that the gearbox is on its mounting, I can remove the engine again, then I can weld up the plated to my cross- member nice and strong ( I hope!).

Ignition challenge next. After trawling through the shed, I now discover i have no distributor, and have ordered an electronic one.

Will I need the ingiter? How do I wire up the igniter to the coils and the distributor? My haynes manual doesnt show the circuit.

royal · June 01, 2007, 05:45:25 PM

Great thread Martin. Proper car modding, not just screwing on a plastic nose and shiny wheels! I wouldn\'t know what to do with anything that had a distributor attached to it :-) I\'d probably break it in frustration as well! Good luck with the project.

an electronic dizzy should have two igniter\'s bolted to the side of it, both igniters have two connections, a C connection and a B connection. One is to the Battery and one to the Coil

no idea which is which :Giggle

best check that info before wiring it all up though

Martiny · June 02, 2007, 07:02:12 AM

Thanks Mike. Between the RX-2 diagram ( with an error) and the RX-7 one, I think I have it working. Except, as far as I can see, only the Leading has a condenser... does that seem right?

Exhaust manifold nearly finished.

Today will clean up Carb and maybe see if it will start.

Martiny · June 16, 2007, 06:01:12 PM

Oh dear , it wont start. No compression on front rotor, 4 bar max on the rear.

This is with some oil down the carb, too! :-(

So , I have to rebuild it. It lay in the shed for 3 years, and it was lying somewhere else before, that, so I guess I was optimistic expecting it to run?

Can I still make Retro show 7th July?
