Posted 31 May 2018 - 09:16 PM

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)
 
mQefhCb.jpg 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!)
 
 
LnT5HNk.jpg
 
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...
 
jFJykLR.jpg
 
https://i.imgur.com/Lw1e4Lx.jpg
1990 UK spec '5 with 1.8 conversion 
as you can see, my 1991Discovery working for its living  :driving: 

pSSCu8Z.jpg
 
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:
 
HI3Cc3W.jpg
 
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....
 
rv9pnnU.jpg
 
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:
 
OCVcNhg.jpg
 
:rant:  :rant:  :rant:  :rant:  :rant:  :rant:  :rant:
 
so had to remove both lower wishbones....

3 out of 4 camber-adjustment bolts snapped :rant:
 
P3zjRie.jpg
 
 
weld to the rescue & re-captive nuts  :thumb-up: 

 
 
 
random stupidity & reading crap on forums later ('Coil-On-Plug' conversion ideas :dance: )
 
FzBLFKX.jpg
 
1j1m13F.jpg
 
ready for future turbo conversion (thats my excuse....... :whistle:  )
 
mA3fRgN.jpg 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........

So, donor car stripped, being the genius that I am, I've decided NOT to convert my 1600 car to 1800 so I've wasted time / effort & oxygen buying a breaker for the conversion parts (engine / loom / electronics etc...)

 

https://scontent.flt...e6e&oe=5BBB20BA

 

I might have got a little excited when dismantling (dismembering?) the car so now its missing a few more bodyparts than shown in the photograph (like the drivers side bulkhead where the pedals fit - helpfull with my ideas on a twin-circuit / bias adjustable brake system)  :whistle:

 

on the upside, I have a front-end section so can 'dummy' build intercooler ideas IF I ever get around to turbo stuff.......

 I stopped updating this thread when nuts went fucked (but continued to post rubbish on mighty5s :banana:  ) then most of the photo links died so have made the effort to host some more....
 
heres a few that might fill some gaps :yes:
 
found this photo when going through the random's on the craptop, this photo was taken when I removed the cobalt exhaust to 'quieten' it (removed the comedy tailpipe & replaced it with some plain pipe). also it's scruffy below and maybe can see the 'flat' floorpan-frame chassis rail on the passanger side :rant: one of the 'to-do' jobs...
:yes:
AgVzCXo.jpg
 
the revised (& quieter) tailpipe, I used some scrap steel exhaust (probably from a mk5 transit) as a trial but it worked well, maybe I should clean the soot from the bumper :thumb-up:  
 
the standard cobalt exhaust was just too loud for my liking (& considering that I've been around rallycars for nearly 30 years that says something!)
7CfUIHs.jpg
 
these are the 'spare' dashboard-switch plugs that one day I'll trace, possibly rear heated screen & unknown? :trigger: maybe now as they are hosted I'll get around to it 
DZTSUaS.jpg
 
drunk in charge of ebay, okey, I was drinking tea but you understand... :wallbash:
it's an m45 from a Mercedes of some kind. the pulley is now removed and a 'kavs' replacement / reduction pulley fits the shaft so theres the possibility of diferent speed ratio's using pulleys made for the newgen Bavarian-Murder-Weapon mini's....
I'll fabricate some brackets over the summer & play with it.
uvtUayx.jpg
 
a random visit to a local car dismantlers supplied the lucky find of a hard to find early Kia Sportage front diff with the 4.778:1 Crownwheel & Pinion, these can be re-built into a post '93 mazda diff for a somewhat lower ratio (perfect for me as I'm looking into some club level hillclimb & sprint competition)
for anyone interested, this is what the complete assembly looks like.
vnAL1TU.jpg
 
ffoE638.jpg
 
ug40OSM.jpg
 
QEEEReu.jpg
one of the many possibly pointless fiddlings I've done is to blank the 'thermo-valve' on the inlet manifold and delete it's coolant-feed pipework (from the thermostat housing to the inlet maifold through the Idle Stability control valve), this photo shows the ISV air pathway plugs, I was intending to completely remove the ISV & make a blanking-plate for the throttle-body but decided to leave it in place to have the ecu's loom connection plugged in so no possible fault-codes :trigger:
3MUvOZo.jpg
time for a recent underbonnet shot, shows the enginebay (needing a clean) and that I've started simplifying the loom (removed the insulation tape and conduit to assess). also shows the Toyota Corrola based 'Coil-On-Plug' conversion and dodgy home-made breather can (cycling drinks bottle)
T3vPkM4.jpg
 
I've posted around this & another forum about my workshop, well, this is some of my workshop. theres a lot more in the way of tooling and machinery 'hidden' (think Buried' :rant: ) including another lathe, milling-machine, body-straightening dozer and 'god-knows-what' else in there....
pHufj82.jpg
and 'old-faithfull'. this mig set must be nearly 30 years old now, bought new & very much like triggers broom (same set but had a few umbilical / torches :rofl: ). I've also got a Camarc 'spool-gun' set for remote welding of steel & thicker aluminium but thats sorta under some junk at the moment) a few basic 'arc' sets and a small hf tig set.
as to headshields, the 'posh' Speedglass (and airfed with the Adflow units) ones are in the photo but theres a few cheaper & older 'favourites' that get used for the dirty but fume-free work.
fSccJs9.jpg
 
hosting & posting has taken ages so I now need some time to recover :cry:

my t4  & mk2 golf, both 1.9tdi converted, once one of them has a bit of weld added I'm putting the '5 in to dry & have some fettling B)
 

annoyingly, I painted the floor (red) less than 2 months ago and it's not stuck :angry:

(lastnight)



connected an Elloit tacometer to the car's loom, this was to test the engine's tacometer signal would trigger the tacometer (to many uses of tacometer??)



so, success 8-) the car operated the new/old Elliot 0-10K tacometer so future bogde, sorry, I mean Modification is to adapt a spare dash cluster to accept the diferent guage, might even go for a 'real' oil-pressure and water temperature guage conversion as I've a few in the garage / mess / stash / hoarding P-)



Sb4ckwh.jpg



I know the bezel looks pink but i think it was red once (rofl)



all this because the Elliot has a 'tell-tale' recall function (see the switch used to test, will be a press-button), usefull to check on how the mrs. is driving :P 







also, been playing with the flywheel ideas......



I bought an 'XTD® PROLITE RACING FLYWHEEL / 90-93 MIATA MX5 1.6L' from ebay USA, arrived within a week (from California) and looks to be worth the punt...



https://www.ebay.co....5.c100012.m1985



before anyone suggests that I should have purchased an 'xyz' 1.8 sized flywheel & clutch from 'xyz' I have reasons for the lightwieght 1.6 size setup.....



I'm intending to use an AP Racing 7 1/4" (184mm) multiplate competion clutch setup so a 1.8 flywheel will not accept the smaller diameter clutch cover & plate (also would need a lot of 'spare' machined away so a waste of time, money & effort)



81dUXv6.jpg

shows the flywheel with a clutch on top (not fitted yet as need to machine a 'step' on the flywheel to create the pressure-plates 'clamp'), a spare pressure-plate from the flywheel side, a 'paddle' plate and also a rusty 1.8 flywheel.

p8iasy8.jpg

shows the flywheel's clutch face (before machining, annoyingly my 1950's era Kerry lathe is a little too small to swing this flywheel so I will have to pay someone else for the pleasure embarrassed.png )

sH6t3Da.jpg

the engine side of the flywheel.



when the flywheel was delivered it was painted / coated in a black finish of some kind, as I am intending to modify this I removed the 'paint' and this is why the surface finish looks scratched asleep.png

as I've mentioned my lathe being to small to swing the flywheel, here she is 
MVkZ7Gv.jpg
theres a 1.8 mazda crank between the centres for scale (and a pair of cams across the bed)

not much progress to report...

so, it fits (after some distruction inside the Mazda cluster backing)
 
gKWiCQD.jpghttps://i.imgur.com/gKWiCQD.jpg]
 
incomplete 'trial' fit photo's, need to make the mount-plate & fix to the case as the Elliot revcounter is a bit taller than the available space 
also need to decide on the adapting of the electricals as the mazda uses a 'membrane' type feed system on the cluster & the new guage( or guages if I do oil & water as well?) will need space made between the 'tracks' for the mount-studs & also power / trigger connections...
 
oLRu8mI.jpg

 

oLRu8mI.jpg
I'm using an early UK spec Mx5 dash cluster as it has less warning-lamps (lightwieght ?) BUT has the rear foglamp illuminated icon so MOT friendly - my car Being a Eunos so made for the jdm market had no rear foglamp or 'tell-tale' on the dash when illuminated...

More fiddlin.....
 
been looking at loom simplification, luckily I have a spare front loom so it's laid out on the floor & considered....
 
must print a wiring-diagram & ecu pinout so I can trace the 'keepers' :rolleyes:
 
fbcLijg.jpg
the whole section (less the dashboard loom as that stays on the dashboard...)
bldbtrv.jpg
the drivers side, note that the bulkhead grommet is mostly missing (just to the left of the 90* bend by the fusebox) so if I actually use this loom I'll have a bot of thinking to do - mil-spec bulkhead connectors maybe?)
FC6Nf04.jpg
the 'mid' section, the ecu plugs (2) are on the right, this is a pre '93 1.6L Eunos loom so there are slight diferences between this & UK spec as well as the '94 1.8L looms like the dashboard loom connectors! - ask me how I discovered this >:D 
G0F9axN.jpg
passanger side.....
 
I'm looking at trimming the engine / ecu wiring & aircon 'extras' as I will be buying a 'stand-alone' ecu & making a new loom (new wire, no old cracked insulation etc) and the ac stuff is redundant so I'll give it a 'Wheeeee-test' (throw it & see how far it gets :lol:  )
I'm also thinking of running a heavier wire for a rad-fan system with a relay so theres no issues, probably something else but I cannot remember......

Posted 17 April 2019 - 11:25 PM

so, today (well, yesterday) picked up an autobox for development purposes...
 
well, they have a seperate bellhousing unlike mazda's manual gearboxes so *hopefully* this is a step closer to running a non-mazda (ford) gearbox........ 
 
possibly :|
 
reasoning behind the ford gearbox? 
 
easier availability of competition clutch components at sensible prices. 
easier to get close-ratio gearkits (& many diferent ratio's).
easy to maintain / rebuild.
easy to convert to 'Quick-Release' from the bellhousing (4 bolts)
I've built & re-built many.
I have several standard donor boxes in the shed & ( used spares.
I have a new Tran-x Straight-cut / close-ratio gearkit, heavy-duty selector-finger, new ford shafts / bearings etc in stock. ;)
being diferent.
because?
 
 
anyway...
another terrible iphone photo :P
 
yEDJRbQ.jpg
 
interestingly, the mazda auto bellhousing is about* 7" from engine to gearbox face, same as the ford bellhousing that would fit the Type 9 gearbox BUT the flywheel / clutch / spiggot-bearings are closer to the engine in the ford setup so should allow for an adapter-plate....
 
hopefully....
 
some measuring / guessing / hopefull prayer to be done :-S
 
otherwise I'll weld the Bastard 
 
 
 
Rich.
 
 
 
 
 
* About = measured with a tape-measure (box of inches) without removing the bellhousing & not wearing reading glasses......

went diggin in the shed, an empty T9 gearcase & tailhousing was found and placed on the auto-bellhousing for scientific purposes...
 
8AMcX5w.jpg
 
so now have an idea of the size (okey, I've already done some basic measuring so know I can make an adaptor-plate to link the bellhousing & gearcase)
 
zmTEyMu.jpg
 
placed a mazda 5 speed gearbox next to the ford one, bit of a size diference!
 
so, to fit a ford gearbox on a mazda auto bellhousing, an adaptor plate of around 1/2" thickness between them (size needs to be fully asessed as the ford 4 cylinder input shaft has diferent spiggot-spline lengths compared to the mazda item, some thinking & measuroing to come...)
 
also, the mazda gearbox is longer than the ford, once an adaptor-plate is added to the bellhousing theres still around 2" diference, luckily, theres a few options of 'cranked' quickshift gearsticks available for the ford gearbox so should still be around the 5's gearknob position.
 
 
more to come...

more lack-of-progress....
 
fitted the auto bellhousing on a spare 1.8 engine, this was to easily measure the hight of the flyheel's clutch-face from the bellhousing's gearbox face...
 
if3XxkO.jpg
theres an engine in there somewhere.......... :lol:
 
o5Vj40e.jpg
 
rediculously, the only ford input shaft I could find was the new Tran-x sccr item (half started box build, one-day project), photo shows it inserted into the spiggot-bearing with the clutch splines inline with the flywheel's friction-face....
can alos see that the bellhousing's gearbox face lines up with the input-bearing's snap-ring that positions the bearing in the gearcase. lines up perfectly BUT that means no room for an adaptor-plate.
 
Arses.

so, next job, find the length of a ford v6 input shaft (the 4 & 6 cylinder engines that had the t9 gearbox used diferent length input shafts, v6 being longer...)

 

then I should be able to design an adapter-plate B)

luckily, theres a longer shaft available...

 

https://www.3jdrivel...0-10000-612.jpg

 

shows the extra length, enough to make the space for an adaptor plate, possibly the spiggot will need shortening, will measure the depth from the mazda flywheel to the crank.

So, lastyear I bought a Jenvey inlet manifold with the intention of possible throttlebodies fun...

today I bought a pair of Weber 40 DCOM Carburettors to adapt as throttlebodies cheesy.png

s-l1600.jpg

another ebay error maybe but from the photo's & listing they are new in boxes / unused so shiney at least.

why carbs as throttlebodies you may ask? well, Jenvey (& Webcon) based their TB's around Weber's icponic DCOE series but removed the carburettor stuff & fitted injectors, I'm intending to seal the bodies & fit injectors in the manifold as luckily Jenvey cast suitable bosses there so a little drill / milling operation or two will sort this wink.png
also, these carbs were a lot cheaper than a pair of Jenvey TB's and similar priced to a set of bike TB's so no real contest. if they look to be a lot of work then I can re-sell them & sort another setup cool.png

*luckily* I have a webcon throttle linkage & 4 'rampipes' (trumpets) for 40DCOE carbs in 'stock' from an un-started build on someone else's car (1963 Lotus7 1500Cosworth) so things are starting to come togther

Hopefully.......


And...

ebay again.

so, I decided to buy a cheap eps column & have a lookse....
HYUNDAI I10 eps column on ebay for the huge sum of £29.99 posted wavey.png

hopefully it will be as in the photo with the control-unit & driveshaft / universal-joints as the uj's will make adaption so much easier smiley.png

I've chosen this as...
1, its cheap so not a huge loss if it does not look like it will work plain.png
2, it looks like it's small enough to easily fit in the space available?
3, it's not a Corsa column - the corsa 'b' column's are commanding a premium price as they have been the mainstay of EPS conversions forever & are now getting somewhat screar canoe compared to a few years ago... Corsa 'C' column's are cheaper but can have issues as they are mostly 'adjustable' with a coupling in the shaft so not so easy to adapt?
4, because? 

luckily I have a spare '5 steering-column so can make a jig for the mount positions & maybe 'borrow' some parts pirate.png


now waiting to see what gets delivered shocked.png

more ebay sillyness shocked.png

I've always disliked the route Mazda used for the lower radiator hose (okey, I understand it was standardisation for aircon pump clearance). but as my car had aircon removed before I bought it theres no reason to have the hose close to the exhaust manifold when theres plenty of room to reroute away from heat...

so, ebay and looking at other things I tripped over the shape of the Lower Radiator Hose Water Outlet Elbow for Mazda 323F. part number B6BF-15-161 , found a seller in Cyprus that has new items for £16 posted (possibly plus import? will find out plain.png also, will UK Mazda dealers supplu for similar prices??? )

basicly aims straight out of the waterpump & has the port to take the metal heaterpipe so no further modifications.


next to look more into diferent radiators, thinking 90's Polo and an expansion-tank system wavey.png

been diggin.....

I had (somewhere) a Webcon twin-cable / lower mounted throttle linkage for DCOE type carburettors

Uy82DDI.jpg

also 4 off Weber rampipes for 40DCOE and 6 off 45mm Jenvey rampipes (fit Jenvey throttlebodies, Weber 45DCOE & Delorto 45DHLA carbs )

7CRK1xh.jpg

so, if I remember correctly, a 40 DCOE (& maybe DCOM?) carb with no aux venturi's or choke-tubes has an airfilter-side bore of 45mm, if this is correct then the jenvey rampipes can be used on 'empty' DCOM carbs used as throttle-bodies 

hopefully smiley.png 

more bits coming togther cool.png

EPS column stuff...

http://mighty5s.com/...&scrollTo=39642

also the 40DCOM Weber carburettors arrived, now to sort converting to 'empty' or dummy Throttlebodies pirate.png

so...

sorta fit.

BUT the carbs have longer throttle-spindles than Jenvey make to suit the 1.6 manifold
gkVyPrp.jpg
the angle that Jenvey make the throttlebody manifold to give clearance in an MX5's engine-bay (clutch master cylinder is sorta in the way on RHD cars) as I have horizontal carburettors they would not realy like to run at this angle efficiently plain.png  
not a problem using them 'empty' as throttlebodies and fitting the injectors in the inlet manifold.

into it's mouth, on the left are the carburettor's 'aux-venturi' & 'choke' tube, these are for the 40mm bore size. on the right I've removed them to show the 45mm bore that steps-down to the 40mm diameter of the throttle butterfly
