hi its an eaton m45 , basically its a mini supercharger, went with mounting it low down so I didn't have a big hole in the bonnet, once I had that mounted I made up an idler pulley and ran the belt from the front pulley (ps pump) round the idler to the s/c pulley, then working backwards I made an inlet and piped it over the engine mount up the passenger bulkhead to pick up an adaptor for the bypass and the second throttle body (no electrics just the butterfly) from here I piped round the rear of the engine to the airflow meter and air filter.
from the s/c outlet I made an exit with a small dia pipe pointing rearward towards the bypass outlet , fitting the bypass valve inbetween . going forward a large dia pipe going S shaped upwards to a VW Passat intercooler , the I/c outlet joined to the original throttle body. the air temp sensor is relocated in the I/c outlet. This gives the ecu the most accurate air temp before the plenum chamber , the airflow meter right at the start has to give the ecu the most accurate airflow reading as its the only way in for the air.
sorry to be so longwinded . there is a good write up on mx5nutz about a s/c install loads of pictures and photos of inlets outlets if you go back through my build photos you can see how I did mine.
Oh I also rotated my front water outlet by 180 deg , gives a tidier run to the polo rad and clearance for the i/c also modded the block inlet as the s/c is in the way so instead of the return pipe coming from the passenger side it now comes under the s/c and up to the inlet.
if I can be of any help , questions or pics just shout :)

well catching up with all the wee jobs , so filled the gearbox and turret with oil, wrapped the exhaust manifold and cat, trimmed the handbrake and gear lever, put clips on the bottom side of trans tunnel top to catch on chassis rails and put gear knob on. hopefully starter motor will be here tomorrow and I can get that in... then back to work on wednesday :( so it will be back to weekends on the car

well the thread title says "progress at last" well very little today , welded in my vin number plate PLEASE NOTE IT IS A PIG TO DO NOW so a word to the wise apply early on in your build and do it before you get to far on.
A wee something to smile about though, after being not very happy with the quality of the chrome headlights I bought and weeping at the price of stainless ones I found an ad for stainless 7" headlight bowls in the states , said they were happy to ship and it cost me under £100 the pair shipped and with priority customs clearance. so the postie delivered them today and I fitted them very happy with them and the service, we will see how the quality bares up with british weather but it cant be any worse than the others.
on a down side I still have a starting problem and its causing me some grief.......... I need to sort this out before I can do anything else,
symptoms are;
it was starting fine but while doing other jobs it hadn't been started for a few months,
fresh charged battery, power at the hot solenoid terminal and power when key is at start at the wee solenoid wire, good earth but no cranking not even a click from the solenoid, tried bridging the solenoid terminals and the starter spins but doesn't engage the flywheel to turn the engine. So ordered another starter (used) and exactly the same issues.
Any ideas ????

haha sorted, IT'S STARTING, some idiot (me) had made a mistake when I wired in the switches which meant I was dropping voltage on start, so a wee bit of rewiring and its starting on the key :) :)
so with her starting again , drained and refilled with anti freeze in the cooling system, ran it so all could come up to temp and surprise surprise my red exhaust wrap isn't red no more ... oh well such is life .
Soooo with all ok I tried moving her under her own power for the first time in the courtyard , just forwards and back and round a bit , what a moment stupidest grin you've ever seen ... lol , I think I need to cut the lock stops down as they really have limited the steering lock so I will pull that apart again and adjust

Brilliant fair play

thanks , its really good when you have good days and things go right :)

Glad you found the problem and fixed it. And I know what you mean about the stupid grin when you move it for the first time on its own.

day off work today :) so pulled the steering rack ends apart and chopped my lock stops in half. its a lot better but I could have taken a bit more off.. maybe later.
it's snowing now and the beach is 50 yards away !!!
made up and painted my battery strap, and picked up my vin plate from the trophy shop , masked the details so that they are in little boxes as per iva manual and sprayed the remainder black. so once dry that will go onto the bulkhead. Incidentally I opted to leave off the max permissible weights, as in the notes it says these are optional, so one less thing to be pulled up on.... I hope.
my list is getting shorter :)
Im trying to come up with a neater idea for the steering column / stalk covers as I'm not 100% happy with what i've done but if the push comes to the shove it will do for now

redid my column/switch covers and I'm a lot happier with them, changed some non std fuel pipes for pipes with the required std on them tidied and secured the headlight / repeater wiring and fitted the wideband sensor / controller (and its still starting and running ) :)

well not much done today, finished the boot lid catch and sealed the bulk head I have about half a page of jobs and then it will be time to iva apply... gulp

just in and managed to get some wee jobs taken care of and crossed of the list, quite chuffed as attached the bulkhead vin plate, doesn't sound like a big step but it makes it feel official , also scary as it means its getting close to iva application time :o
spoke to a very nice lady at vosa yesterday as their website didn't include Aberdeen test station and I thought that I would have to go to Edinburgh, lol , straight to the test and straight home officer, yes 500 miles round trip, after she finished laughing she did confirm that Aberdeen do the test. So it will only be 60 miles each way.
Any way I'm going over and over the car trying to be brutally honest with myself and be critical of everything, once I think I'm close I will try the local garage to do an emission test so I can see where I am on that.
Gary

a few up to date pics shows a wee bit of progress and also discovered a couple of issues to sort out , but getting there:)

Looks good :)

well got the headlights shining the right way today and went and saw a friend who is going to put the car on the headlamp aim at the garage and pushed my luck so he is going to do an emission run and brake test as well , next Saturday is mums birthday so it will be a fortnight after that at 7am :)
"If you don't mind being early just bring me a bottle of malt" was his comment so sorted at least till I see what happens .....
so I need to crack on with a few other jobs and have a bit of a push. I have in my head to aim for iva before easter if I can

well nothing done this weekend :(
mums birthday (you cannae miss your mums birthday) and its snowing n freezing today, so planning an attack next weekend :)

Oh NO what have I done now :) gulp.........

Hi Gary
Nice to see your going for it. I must admit I started to fill mine in on Friday in work but haven't had the bottle to print if of and send it.

Hi Matt, yeah I printed it out and kept looking at it and going over the car in the end I thought right.. you can keep looking and fiddling from now till doomsday... so went and got a big envelope printed off a selection of photos, the mx5 parts engine number / year of production info, copied and signed the receits / invoices for my NEW chassis steel and chassis plates, all my major '03 mx5 parts. Made sure I had filled signed and dated the iva app AND the amateur build declaration. Parceled it all up and went round to the post office. sorted that's that then, came home and went straight out to the car with a notepad, mmmmmm
Still I put that she would be available for test from Monday the 21 of march at Aberdeen, sooo, a deadline looms, nervous yes, excited yes may need to take a few days off if it looks tight, she is going to the local garage next Saturday so will get the headlights set the brakes checked and an emission run done, noise it makes some but will try and get a meter and see where it is at.
worst case is I get a fail but with a list of fixes, everything right to the nicky nacky noos crossed that a pass is in the offering :)

ok so ticked a few more wee jobs off today ...... made version 3 of the remote brake fluid reservoir, I used a focus reservoir, got a plug mmmm 3 wires, still its only a float switch, haha no matter what I did I could not perm the 3 wires to the mazda 2 wires and get the fluid level warning working ... So after much mucking about made an ally bracket to take the big round mx5 reservoir positioned it and reconnect pipes, handbrake off ... light on :) fill up with fluid ... light off:) handbrake on .... light on :) happy bunny so trimmed the requisite fluid sticker to size and put it on the reservoir cap. SORTED at last.
moral don't mix manufacturers !!!!! started hailstone and rain so came in . Next is to disconnect the neutral switch and sort out the twin T/Bs :)

so went out and started attacking the 2 throttle bodies no matter what I did It still wasn't right, searched about compressor surge causing problems, so checked the bypass was working... yes popping open n shut like a good un,
Then the old fella next door came out to see if I needed a hand... he couldn't and didn't want to attempt to slide into the drivers seat and asked if it was ok to work the throttle by twisting the linkage, and guess what no running on a steady idle, clean pick up and drop back, now whats the problem ????

a badly routed throttle cable from the pedal was causing enough friction that the linkage was dragging so iffy pick up and not returning cleanly.

so re did the cable checking the pedal was free and the cable was free and guess what its all behaving from the drivers seat and by twiddlingt linkage
MUPPET moment

still at least that's all done now

email from vosa confirming receipt of application and giving a reference #

Gary
I'm wondering if you could help me out as we have got the same engine. My wiring diagram is showing a second data connection under the dash OBD2. My question is Do you have an OBD2 connection under your dash as I cant find one on my loom but I'm thinking I'm missing a bit of the dash loom with this connection on. I've been reading up on this and Mazda started to fix the OBD 2 on the mk2.5.

cheers Matt

arghhh, I don't have 2 of them, I seem to remember chopping a heap of wiring out that had one attached, and the other one had a load of abs related stuff going into it and I am pretty sure there were only a couple of wires left by the time I was done.
Sorry I cant be much more help, my mil light was on and no matter what I did it still glowed grinning like at me, so, not good practice I know, but there is a spare bulb in my tool box now . some one will probably tell me I'm not allowed to do this ... but I have

just in from work to find an envelope with all my receipt copies, but no build photos returned, checked emails to find " your application has been accepted, please pay" so will get them paid first thing in the morning , I guess they open at 9am?
panic, relief , excitement :)

well a very nice lady relieved me of £450 today , so iva paid for , then got an email that it is now sent to TaSS (testing and support services) for processing :)

just back from the garage and it passed the emmissions BET test, headlights NOW correctly set and was reading 95Db at 3000 revs, but that needs to be checked at 4000 my fault as I trusted my memory (must be an age thing) so will do that again later on.
On another positive after sorting my sticky throttle cable it is so much easier to drive, 2.4 rack + supercharger power delivery certainly makes her a sprightly little beast :)
so a spring in my step today.....

Best of luck with the IVA :)

TT

thanks, I'm trying to go over as much as possible, edge trim, nut covers, things clipped down.... I think I'm getting paranoid.. lol
I guess the stress level will go up even more once I get a date confirmed :)

well put nut covers on today, trimmed a couple of edges that I found on the bottom of the headlight bracket, secured the heater/ header hoses onto the bulkhead sorted the radius on the trip button, was really worried about the viewing angles of my small front indicators so took them off and ordered a pair of '70's style chrome bulgy ones for the test so it should be ok on the 20 deg side view. ordered a new rad fan as mine looked untidy. and reset the rear brake adjusters now the handbrake holds like a good un.
So still to do; trim under dash in footwells, fit a new reverse switch as its playing up, pad steering wheel center, keep going over bits and pieces, found out I needed 2 odd size nut covers for the exhaust bracket so ordered them.
Does any one know the thread size of mx5 tre's as I have castellated nuts and would rather nylocs

Garf ☺

cheers, for that
missed a phone call from a private number because I was driving into Aberdeen, turns out it was the test center admin trying to arrange my date in Aberdeen, lol
got a really polite email explaining and asking me to call them to arrange, even gave me a direct call number, so will get that sorted tommorow :)

got a date today when I spoke to the lady at aberdeen, 24th March at 8am , she said it has to be full of petrol and bring a wee tool kit in case there is anything minor that can be sorted, she also said to allow around 5 hours for the test.
she is going to send a confirmation email with all the details


Really nervous now :O

Good luck im sure it will fly through

cheers Steve, I phoned footman james today to get a quote for insurance on the vin with change to official reg once dvla supply it, 5k miles pa... £168 for a Haynes with an mx5 1.8 and supercharger :) so this will be in effect the day before the test.
The lady there was really helpful and knolageble
So now to finish off those frustrating little bits n bobs and keep looking for anything I've missed

just mounted a new fan (peace of mind) on the radiator, and moved my front indicators forward as I was worried about the line of sight angles, a couple of other jobs, nut covers everywhere front and back, checking wiring is tidy , undersealed the floor underside, nylocs on the TRE's instead of castleated .
still to do pad center of steering wheel, new reverse light switch, trim footwell :) and keep checking stuff

Good luck.

Keep up the attention to detail and you should sail through the test

Arfon

cheers guys I'm getting really anal about going over and over her, got some black suede offcut today and made a padded center cover for the steering wheel found the number plate light wires had no grommet so now they do :)

Keep going over and over it will be the little things that count in the end
