Rotary and General Chit-Chat / Valuing my 20B FD3
« on: May 02, 2017, 01:30:26 PM »
Okay.. always an interesting subject as it partly comes down to what people are willing to pay.. but it is getting time to insure my beast for the road and I will have to put a value on it. I am interested to know what peoples thoughts are on the value of a 20B convert FD3 in the current market.  I don't think too many have been sold in the UK which makes it tricky! I think maybe Mir20B sold his a while ago but not sure if it broke instead or what?
Thoughts please guy's.

Thank you

Pair of Mazda RX8 18" Wheels 5x114 fitted with 225/40/18 tyres. One is a kenda Kaiser with lots of meat left on. The other is a Potenza which is about half worn. Wheels are straight and true with no cracks. A few small kurb marks and could do with a clean up but good other than that.
£50 the pair collected.

Rotary and General Chit-Chat / Call All Electrical guru's
« on: January 14, 2017, 07:54:05 PM »
So guy's, I have a idle control issue with my microtech ECU where it is essentially a bit basic and does not have some quite key functions. So I want to try and plug something in to create a work around for the main issue I currently have. That is poor idle due to voltage drop when any electrical loads are applied such as fans.
The work around I want is this. I want a wire something in off the back of the alternator or any other 12V wire I guess that reads the voltage which under normal running will be around 14.2 volts with a good battery. if the voltage temporarily drops down to say 13.8V when a load is switched on I then want this to flip a switch which will allow a 12v supply to be sent to an input on the ECU. Then when the voltage picks back up the switch will flip back and close off the 12v source to the ECU. I hope that makes sense. I think this should also only happen when at idle so I guess that means wiring a microswitch onto the throttle pedal or throttle body that is on/off when the throttle is closed.
Can anyone advise if there is any off the shelf item that will do this or if I need to make something and if so what components am I looking at?
One other thing is ideally I want to be able to adjust the voltage that the switch flips at in order to fine tune the point at which this needs to happen.

Thanks for any help.

Cheers

General Technical / 10mm Wheel Spacers on rear?? FD3
« on: November 21, 2016, 09:21:34 PM »
I hate the thought of wheel spacers but need some wheels for my car ad the ones I want will require 10mm slip on spacers on the back of the car. What are the thoughts about running this on an FD? Will I need longer studs in the hub and if so how much of a pain in the butt are they to swap out? Hub off or can you do it by just taking the caliper and disc off?

Advice please.
Thank you

General Technical / Rev counter gone crazy
« on: September 29, 2016, 09:21:25 PM »
My Rev counter goes crazy when I switch the ignition on. Bounces around all over the place. Sometimes it moves normally but I don't think it's reading th right rpm. Rest of the dials seem fine to my knowledge. That said oil pressure sits on 0 most of the time. I know it's OK as I have a mechanical garage in the bay so don't panic like I did first time I happened! I haven't driven it yet and can't so don't know if the speedo works. Fuel and water temp seem to though. Can anyone let me know what the issue is so I can fix it please!

Thanks

General Technical / Finding TDC on a rotary with trailing plug hole
« on: September 22, 2016, 08:04:56 AM »
I have a 20B I have an uncertainty about the TDC with. I hope this can help solve it and be useful to all rotary guys out there.
With a bit of help from a few of the engine builders/tuners/highly skilled members on here I think we can come up with something worthy of a sticky unless I am missing a trick?!
The question about finding TDC on a rotary is one that gets asked quite a bit from what I can tell and most of the answers don’t help if you have your engine built and in the engine bay. Even so what I have read still seems to leave a reasonable margin for error? Such as lining up the keyway at 90degs.
So first question is how would you find TDC for definite when building an engine? Is there a mark defined somewhere internally for this or does it rely on lining up the rotor position by eye somewhere roughly?! I know how you do it on a piston engine and that gives a defined no argument position if done correctly with the correct tools.
Asides the above, that there may be an exact science for, let’s look at those of us with engines built. The only true points we have to visualise are the pulley and pointer at the front and the position of a rotor tip as it passes the plug holes.
I gather that there may be some variations on plug hole position between different series motors but with some input from other people I think this can all be covered.
So my suggestion is as follows:

Step #1
Take a protractor and stick it to the front pulley. Make a pointer to align at a given point on the protractor or use the point on the front cover.

Step #2
Rotate the engine until the rotor #1 has a tip centre of the small trailing plug hole in the housing. Note the position on the protractor.

Step #3
Rotate further until the same tip is centre of the larger leading hole. Note position on protractor. This step has a bit of a margin of error due to the size of the hole and may in fact not be needed. But I am suggesting this in case there is variation between different series of engine on the separation between the plug holes. A physical distance could also be measured between the holes as a double check.

Pause for thought..
If the rotor tip is always dead centre of the plug holes at Bottom Dead centre we could now work out the degrees to get the rotor tip to this point and then rotate the crank around accordingly to mark TDC.. I am just trying to get me head around the reduction ratio and firing.. I think a 60deg rotation would give us TDC though?
My issue here is I believe due to the above possibility that the plug holes positions vary slightly on different series engines BDC may not always fall middle of the plug holes. Someone may be able to confirm this though.

Step #4
This is where the rest of the community come in. calling on all you engine builders, tuners, DIYer’s with spare motors. If you have a part built engine 20B, 13B etc that has a known TDC mark on the pulley please can you do the following:
Step #4a
Align the TDC mark with the pointer on the cover.
Step #4b
Mount protractor wheel to front pulley and note position of protractor relative to engine point or separate make shift point.
Step #4c
Rotate the engine counter-clockwise until a rotor tip becomes visible at the centre of the small trailing plug hole. Note position on the protractor.
Step #4d
Post the degrees you have just marked on here with the engine type you have marked it from and the series/year of the engine block if known or applicable.

I am hopeful we can build a small table that shows how to mark TDC within a very small margin of error using this method. I think it could help a lot of people out. Me included!

If anyone see’s any floor in my plan or a shorter route that I have not consider please jump in.

On a slight side note I have think I have most of the parts from a junk 13B FD engine in my shed. Could I mock this up using the FD trigger wheel to help myself or others with my 20B TDC issue?
i.e. I believe the rotor housings are the same for a 20B and a 13B? So I should be able to follow my above theory to find where TDC sits. And I have the bonus of a trigger wheel that should be marked at a known point as a reference? Don’t recall what the FD has on the cover for TDC alignment actually but I am sure I can find that out.
