I've been looking for a Stack fuel level gauge to match the others I've bought, naturally I was looking for sensibally priced not new so this was on the backburner....

ebay came up trumps so a used white-faced Stack ST3365 gauge was bought and delivered 😎


these have custom calibration options and hopefully can work with Mazda's Yazaki sender resistor.


so, I had to play.

one small 12v battery, a sender, some reading and....


so it works 😎

Now I'm looking for a pwm type Led dimmer as these gauges are a little bright 😮 Autometer / Stack make one but it's ~£40 and only controls 6 gauges (& I have 7 so far and possibly a few more if I get theit matching Wideband 02 gauge)

more ott faffin to follow.

something I've been looking into is a quick-release steeringwheel hub, many benefits of these include security & ease of access / egress, I had a cheap generic type in the workshop but was not unsure on it so bit the bullet & bought a known-quantity (& Quality?) hub.


Racetech RTQNY Quick Release Coupling


this type bolts onto a Momo/Sparco etc. boss (saves welding the splined 'slug' onto the column) and also acts as a spacer (handy), this type is also FIA & MSAUK approved for motorsport so a quality item 😎

next to find a solid steeringwheel boss to mount the Corsa column then bolt this Racetech qr onto as I'm unsure of the oem Mazda / momo colapsable boss with the extra length & in competition use :unsure:

I never like the weld on spline.. i had 1 on my westy... gotta trust your welding lol.
I want 1 in the 5 tbh.. maybe jan sales...
Id nick the 1 out of the 7 but yeah good security so its staying.

Hello, I'm Zed and I have a problem.....



and its in 50 shades of silver (on a good day!)


also....


just bought another tachometer :eek:


a secondhand Stack ST400 (8krpm) recording tacometer with programable shiftlight :cool: (has paint / overspray covering so needing a clean)


interestingly this has a '909' part (Finis) number so a Ford Motorsport item (it's from an Escort Cosworth rallycar!)

so now theres more re-wiring of the dash-cluster.

NEXT.

no real progress but more pieces of the puzzle are here....



the Racetech QR hub has arived, its a solid item and will add 58mm to the column so a usefull extender.


the connection is via a splined stem with a 'master-spline' for repeatable 'foreward' positioning of the wheel, when connected theres an audiable 'click' to announce this.
I had considered buying the (cheaper) 'weld-on' spline section but this allows length adjustment as spacers can be added
between the qr & steering column's boss.


been playing with the LSD, decisions on what ramp-setup to use as there was the choice of 30/90* or 45/45* - photo shows assembly as 45/45* (was delivered as the 30/90* easier to drive option)


pressed bearings on the diff unit,this was done with the LSD stripped so no possibility of distorting the case or endplate.


bearing fitted, used an old bearing 'inner' race as spacer and a smear of grease on the sholder as witness to show it was pressed fully home (grease visable lower right of bearing / diff)


the Stack ST400 revcounter has landed, it's a little scruffy but I'll let that go as I've bought a ~£500 gauge for 1/5th of it's new price:eek: this typically didn't come with it's wiring-plug or switches / shiftlight so I'm hunting for replacements 🤨

will test it tomorrow...

I'm full-speed on the Landrover's 200tdi engine conversion and rear axle replacement on our B3 Passat (all weather dependant!) so no time actually on the Eunos:(

more fiddlin....

was doing some other work and needed to tidy the workbench - tripped over the Mr2 drive-flanges so thought it time to compare with Mx5 flanges...


pressed the studs from the Mr2 flanges & tried against an Mx5 flange.


closer view, the Mk2 Escort RS2000 type extended wheelstuds are handy for this.

the Mr2 flanges require some machining to match Mazda's dimensions but nothing hard.


this photo shows the difference between flanges, the Mazda item is thinner and hopefully the Mr2 item is stronger 😎

next to order more RS200 type extended wheelstuds, Mx5 rear wheelbearings (again) and get machining...

subject of hubs, I'd sandblasted & painted the uprights but the paint has allowed some rust to break through so I'm tempted to send them off for electro-plating, thinking yellow zinc along with the front uprights & maybe subframes :unsure:

more thoughts re. rear hubs / flanges / discs & calipers...


back onto the Hispec / Ginetta rear 2 piston calipers....


tried a 'half' on a mk2 sport disc with a pad in place to space...


looks like a viable option...


the rear pasd are from a Mitsubishi Evo 6/7/8 so plento of options available.


radial-mount calipers and what looks to be an easy mount-bracket to fabricate.

these calipers have 38mm pistons so suitable for rear use and parts are readily available from Hispec's website so I'm going to ditch the standard Mazda sliding-calipers with their tiny expensive pads to use these lightwieght (~850g) beauties.

I'm also tempted on Hispec's 'Spot' (handbrake / parking) calipers but these would need bracketry fabricating & welding to the uprights although this would be no problem...

never enough time BUT too many ideas / distractions / dreams....

:unsure:

picked up an Audi R8 oiltank (they're drysump) for cheap on ebay as an experimental part, seen photo's of these but never in the flesh.

it's possibly getting modified to fit the silver heap 😜


the tank, similar design to that I've been slowly fabricating for the silver mix-n-match. Audi will have looked into many things when designing this so I'll look & learn hopefully...


remote filler, dipstick & level-sender - bit posh innit?


feed in from engine (bolter flange) and a pair of breather - stubs on top (one from engine & other to atmosphere / intake)


feed out to engine (bolted flange) and drain plug - again a bit posh!
wonder if theres a magnet on the drain plug & if so how much 'fur' is remaining from the previous engine???:eek:

more stockpiling / hoarding to follow ;)

subject of stockpiling, bored in ebay earlier & spied an 8x15 (et-20) Eevolution 5 spoke wheel for sensible money so it's on its way here ;)


sorta 100mm more poke than a standard Mx5 wheel 😜

always wondered what these would look like on a 5 :unsure:

just so happens that I know of a set of these in similar size so might go sniffin......

been playing with the dash cluster again.


so it turns out you can fit the facia on an A4 page so an A4 sized carbon-fiber plate 😎

now to measure / mark & cut the holes, guessing this will have a few attempts 🤨

no other progress to report.....

the Revolution wheel has been delivered so I had to try it on the silver heap 😎


some rust starting on the lower arch :cry: also underseal peeling on the inner-tub - the inevitable is happening and I've embraced my future has welding in it...


theres a little poke...


maybe an 8" wide (et-20?) wheel has a little too much poke for a standard Mx5 wheelarch :ROFLMAO:

other developments, I'd ordered extended wheelstuds (Mk2Escort Rs2000) for the Mr2 rear driveflanges and they have arrived - must get around to machining them to suit the Mazda uprights.

more fiddlin...


again looking at the rear brakes, the Ginetta branded Hispec calipers look easy to adapt & making (OR buying???) mount-brackets shouldn't be an issue.


Heath Robinson-esque caliper width spacers :ROFLMAO: :ROFLMAO: :ROFLMAO:


looks to be ~3mm offset for the adapters, not a hard job to make but Hispec sell 'blank' adapters for ~£25 each (+vat etc.) so probably cheaper to buy than make!

subject of buy, Hispec sell spares so seal kits, pistons, spacers and pins are all available, looks like ~£100 (+ etc.) to recondition a pair of calipers BUT new calipers are £100 each so is it better to just buy new calipers?

more thinking to follow....

also, talking to a mate & dash-clusters were the topic - he has a Mk2 Escort rallycar and has fitted a new revcounter so I sent him a photo of the Mazda's dash-cluster & gauges....


I MUST finish this someday.

this landed today, I'll try to source gas tomorrow then can play:cool::cool:

Best of luck with welding. I recently bought a sip gas/gasless mig welder and done some welding on another project. Welding is the easy part. The cutting and the fab work is the real work.

takes more than luck 😜

I've been welding ~30 years & it's sorta my job:oops:

still learning though:cool:

I recently bought a sip gas/gasless mig welder
I'm not a fan of gassless - fluxcore is the devils spit:censored:

Welding is the easy part. The cutting and the fab work is the real work.
yup, this is true, 90% prep, 3% skill & 7% luck(y)

time, clean workplace, clean metal and patience are important - piece & quiet also helps as if you cannot concentrate then things get missed🤬

un-doing someone's previous *&%$ up!

^^This.

if you'd seen some of the efforts I've repaired, both industrially & automotiveo_O

I've worked with a few weldist's, some called Teflon - Non-stick:ROFLMAO::ROFLMAO::ROFLMAO:

I'm not the best but do have a go.......

and have a lot of excuses🤭


remember what I was told as apprentace, "A good looking weld is not necessarily a good weld" - something I repeat regularly;)
