50 Shades Of Silver (Na Eunos)

in January I bought my Eunos, I'd liked the idea of one for maybe 10 years but I'd not had thew time or space for one.
so, heres my '50 Shades-of-Silver (amongst other colours)

as bought and home (ok, I've too many cars....)

replaced the TSW wheels with BBS from a BMW E30 :thumb-up:

the car was imported in 2000 so had avoided UK's salted roads for it's first 8 years life, being a Eunos the online vin decoders are next to useless and the dvla's regestration details are 'suspect' to say the least (it's regestered as a 1992 mx5, I guess thats the importer creating a car thats easy to sell & insure)

the previous owner had replaced the clutch, cambelt & waterpump, swapped to a mk2 dashboard conversion, fitted a cobalt stainless exhaust and a few other jobs like rust prevention.

when I was inspecting the car before purchase I noticed that the pedlebox was cracked with the throttlepedal almost hanging off, this had a major impact on the cars performance (possibly why it was for sale?)

when I got the car home I decided to remove the dashboard to investigate the wiring conversion as well as check the heater pipes & fix the pedlebox (the throttle pedal had actually dropped off after I got home!)


while the dash was out the seats & carpet followed, then I noticed that a rollcage had been fitted previously with holes drilled in the front & rear floors as well as the parcel shelf being cut (not a problem to me as I'm looking at fitting a cage :yes: - wonder what cage had been previously fitted? )

when the dash was out I decided that the conversion wiring was a bit of a mess so started looking for a replacement, this was put on hold for a while untill I spotted an advert for a UK spec 1990 MX5 for sale as a breaker...

1990 UK spec '5 with 1.8 conversion
as you can see, my 1991Discovery working for its living :driving:


little while later, some bits removed :whistle:
was easier to remove the engine by chopping the front of the bodyshell off, nice un-rusted chassis rails - unlike the sills, wheelarches & floors :rant:


dashboard loom needing repair, one of the reasons behind the tango'd 5's purchase....

annoyingly theres diferent looms fitted - unknown if this is age or engine related :rant: :rant: :rant:

discovered after re-building and fitting a mk1 dash into the Eunos :yes: :rant: :baseballbat:

so, ended up repairing the Eunos's origonal....

call for the solder & heatschrink......

bought some Compomotive wheels, unsure if they are destined for the Eunos or my mk2 Golf tdi....


another purchase, set of Ohlins adjustable dampers with springs & rosejointed topmounts, these were 'pre-loved' so a lot cheaper than new (although cost £400 so almost the same as the Eunos)
had fun when fitting, both rear damper bottom bolts were not wanting to undo as their 'captive-nuts' were 'UN-captive' :whistle:


:rant: :rant: :rant: :rant: :rant: :rant: :rant:

so had to remove both lower wishbones....

3 out of 4 camber-adjustment bolts snapped :rant:


weld to the rescue & re-captive nuts :thumb-up:

random stupidity & reading crap on forums later ('Coil-On-Plug' conversion ideas :dance: )



ready for future turbo conversion (thats my excuse....... :whistle: )

twin cylinder adjustable bias pedlebox :thumb-up:

Another 'Random-boredom' idea, I've always had bias/adjustable pedleboxes on rallycars so as the Eunos is hopefully going to hillclimb & sprint its getting one :yes:

this is the 'mk1' design, not a working prototype but just pushing ideas....

the standard NA pedal ratio is 4:1, this is fine with servo asssistance but un-assisted will be harder than hell and a massive effort to stop the car so I'm looking at 5 or 5.5:1 ratio so that means shortening the pedal & moving the cylinder position.

also, I've picked up some new AP-racing 'dumpy' mastercylinders on egay for a very reasonable price :dance:

more to come once I've recovered from typing this........

last time I checked there were some rear arms (cant remember bottom or top) that were unavailable as pattern parts
rear top I believe are not available as a 'pattern' part.

all wishbone positions are ~ £150 each if buying Genuine Mazda (unless you can get cheap on ebay;)) and the only wishbone that ha bushes already fitted are top front - all others have bushes as extras 🤠

subject of bushes, started looking at fitting the 'bushes'....

test fit.

next is to make press-tooling to position them in their 'tubes', will look into a tube-spacer between positions so I dont collapse them if I use the hydraulic press :unsure:

might get an hour later....

how comes the welds are rusting already?
its not rust, its 'glass' from the weld process

So, despite me being wrong, they are in fact still a problem if not removed before being painted.

I've found (I think :unsure: ) similar metal balljoint type bushings that are (on paper) a sorta fit for the front & rear / Lower wishbone inner positions.

from a Subaru (p/n SUBARU : 20257XA000 )

these have a 40mm outside diameter, 50mm length and 12mm bore so suitable for the subframe / adjuster bolts:cool:

I'll be buying one to try :ROFLMAO:

Keep us updated. I am trying to find alternatives for the ball joints and I had no luck i.e.reasonable cost and long lasting . At least on paper. Just to stack some more parts to my toolbox.

Subaru bushing update...

these were the cheapest I could find - it's an experimental bushing so not buying expensive!
these are from Autodoc and are a replacement for SUBARU 20257XA000 bushes.

40mm outside diameter.
50mm wide.
12.5mm bore (for a 12mm bolt).

these are a spherical / balljoint / pillowball type but have a rubber dust-boot so look a little like a conventional rubber bush (from a distance anyway)

boot removed, can see the 'ball'

against a wishbone, should have a 10mm spacer each sise for the subframe 'ears'

offered up to the wishbones tube.

inner & outer bushing positions hopefully finalised, just need time to machine some fitting tooling for pressing into tthe tubes as I dont want to damage the bushes or the wishbones :eek:

maybe on the weekend......
