The last Post.

The rear wing was designed to be end mounted
but I could not make end braces that I
thought looked any good.
So I modified the wing and centre mounted it.

The mounts go down through the boot lid and
connect to the floor.


So that's it.

All finished, Thanks for following.
I hope it was worth the read.

Cheers

Geoff

all most finished. . . . . . . . .

The front guards have been patched and paint
touched up.

Time for the finishing bits.

I made an engine cover from steel in the early
days but have decided not to use it.
I can't weld Aluminium so have pop riveted a
cover together.

The convex interior mirror works very well and
gives a great view out the rear. It makes up for
the crap door mirrors.

The door mirrors look cool and are CAMMS approved
but don't work very well.

At this point in time there are no windscreen wipers
and if I can manage there will never be any.
Just plenty of Rain-X

The Blue Bastard is now driveable and needs a wheel alignment.

Because of the 15" x 8" wheels which have zero off set the
front guards and the under tray required a fair bit of
"opening up" to get the required clearances.

A texta to mark the line and a hack saw blade to cut the
bits off worked ok but it was such a shame to have to
hack into the finished body work.

OMG that's a great build you're doing and it looks too beautiful for the track.

Bryan, you pick what I missed, well done.

The timing checked out OK as did the spark.

I kept looking for electrical problems.

I was using the Honda S2000 service manual for the USA.
It talks about an immobilizer, which I could not find
nor had a remote for, The only Black box I could find turned out to be the
Keyless remote box, for which I did not have the remote for either.

After a lot of investigation I found out that the Japanese
domestic market cars don't have immobilizers and the keyless
remote only opens the doors.

A friend of mine suggested the Fuel injectors might have
fuel pressure applied to them, and an electrical pulse
applied to them, but were they actually passing fuel.

I removed the injectors and had them tested and cleaned
and was informed that all four injectors were blocked.

Once cleaned and reinstalled the motor started on the first crank.

The injector cleaning people said that Japanese fuel is
good quality but has ethanol in it and will seize injectors
if left for a long time, and in my case it was about
about 2 years.

So once started the wiring looms were reduced to the minimum
and installed in the car.

The blue bastard lives . . . . .

easiest thing to check is spark.
If you are getting spark lets discount that as a problem.
Injectors can (Not all) be direction sensitive (I know I had trouble with the ID1000 injectors being wired backwards).
So check that the +12v is on the right side of the injector and in fact they are firing.
Are you sure timing is correct?

Good luck

Bryan

Earths all good. . . . .

The type of ECU I am using "sinks" the voltage to / from sensors
and the injectors so earthing the ECU is very important, all checked OK.

What I mean by sink is.
I will use the fuel injectors as an example.

There are two wires to each injector. One wire is connected
to the battery supply when the ignition is turned on.

The other wire is connected to the ECU.
The transistor in the ECU will, when required allow the power to flow
through the injector, through the transistor to earth, the frame of the
car and back to the battery negative.

Every second time engine rotates the injector is energised for a very short
period of time to supply a dose of fuel to be burnt.

The voltage applied is always 12v (battery voltage) but because it is pulsed the
average voltage seen by a volt meter will be less than 12 volt.

The higher the injector duty cycle and the higher the engine RPM is the higher
the average voltage will be.

This voltage can be measured whilst the engine is cranking
to see if the injectors are being fired.
In this case about 7.5 volts.

Earths all good.

Any other Ideas ? ? ? ?

Howdy Bryan,

Yes I must admit the hand brake thing is a bit weird.
I would not have installed twin hand brakes as a retro
fit in a finished car, but as there where no brake lines there
it was easy.

I don't believe they will be of any use on a circuit track.
Where they might be of some use is on a couple of Hill climb
tracks I compete at.

if you youtube Collingrove hill climb and Mount Gambier hill climb,
both in South Australia you should be able to pick the corners I am
thinking might be assisted by a hand brake on the inside wheel only.

Next comes the electrics.

Having the front cut of the Honda supplied me with the ECU
and all the wiring looms I could ever need. . . . .

The motor loom was installed untouched from standard.

All the other looms are going to be cut down to the bare minimum. The Dash is the standard S2000 unit.

Before I cut anything out of the looms I wanted to get the "blue bastard" started.

So with the wiring connected but just sitting around I attempted to start the "Blue Bastard".

After THREE full days of the Honda wiring diagrams,

The BLUE BASTARD would fuel prime, the dash would go through
it's start up checks, it would crank but not fire.

Every time I came in from the shed my wife would ask how I was getting on and she received the same answer every time for three days.

THAT BLUE BASTARD WILL NOT START.

The name sort of stuck.

Anyone want to guess what I missed and why it would not start??

Geoff,
School holidays and first time poster = spam.
keep us posted with the build, looking good so far.
What computer are you going to run?
Not sure about the handbrake though, not seen a track yet where ive required it. Good for drift and rally though.
Having said that Eastern Creek start line is sloped down hill and that is about the only time ive wished for something other then the brakes to keep from rolling on the line.
But the benefit of the 1200 is keeping the setup light, so you may find yourself changing that later to save weight.
Every bit counts.

Love it so far.

Bryan
