Show your unique/rare mods!!


Some nice mods in here.

I'll have to dig up a pic of the parts but perhaps my stroker kit (Brian Crower) is rare. So, I'm submitting my BC billet Crank :)

how did you fit this m8?

How many BHP run on it??

I'm running a standard b16b with a Simota pod filter being the only modification.


I designed and made a printed circuit board to control the shift light and used the blue/white tacho test wire as the signal to it.

Taking apart the back of the gauge cluster there is a thin backing piece of plastic which all the warning light symbols are printed on to. I wanted the shift lights to be easily seen so decided to put them in the spaces just above the indicator lights. These spaces have the high beam and hand brake lights already in them. Carefully cut these symbols out of the plastic backing piece and also the plastic in the 2 empty spaces. Then replace the empty spaces with the cutout high beam and hand brake symbols. Re-wire these warning lights by tracing the wires back.

The warning lights look black when not turned on. To replicate this for the shift lights I sand blasted a thin piece of clear plastic which is about the same thickness as the original plastic backing piece. This is to diffuse the light. Then cover the plastic with window tint film. Cut pieces to fit the holes where the shift lights are to go and glue them in place.

I used 1 orange LED and 1 high intensity red LED mounted into the bulb socket that holds the original bulb for the warning lights. Twist this in place and wire it up to the shift light controller.

Hope this has been helpful and I’m happy to provide more detail if necessary.
 
That's pretty unique IMO. How much did it cost for the PCB to be done? Also what did you use to trigger at the specified RPM's? I know you said you used the wires from the tach but what triggered the power to the bulbs to come on at the selected RPM. Been doing a little research and wanted to have the whole Tach change color.
 
The PCB itself I made for free using the equipment at the university I'm studying Electrical Engineering at. It is rather expensive to get a 1 off PCB made. If you can keep the circuit simple you can use Vero board instead which is a much cheaper alternative.

The most reliable way I found is to use a frequency to voltage converter like a LM2917. This will change the pulsed tacho signal to a DC voltage. Then send this to a voltage comparator, like a LM293, to compare this voltage with a reference voltage. The reference voltage is adjusted using a potentiometer which is what gives the set point for the shift light to come on. Then the output can be used to switch on a transistor (BC639 or equivalent) then in your case probably switch a relay.
It's also a good idea to power all this through a 12V voltage regulator (LM7812). The reference voltage will then always stay the same and the frequency to voltage converter will output the same voltage for the input frequency/RPM independent of the battery voltage.

Another way to switch a shift light on is to use the circuit on the data sheet for a LM2917 called a “Speed Switch”. It is far simpler but from my experience it wasn’t as reliable as the new circuit I designed and didn't offer me the flexibility I needed. If you can’t get access to PCB facilities it may be the better option.

I have schematic diagrams of my circuit which I can email to anyone if interested.
 
it is not rare but unique and i dont know of anybody actually doing this before.
S2000 rear shocks on eg,dc,ek, it is a straight fit no cutting no welding no bending it fits right in. we put it on my friends crx for drag racing and we ara happy with the results it is stiff as fu**.

a cluster I made years ago. Just to be creative-ish. HAHAHA That's the only pic I have since the car was sold back in the day.
