Yup, I thought the same as I haven't left my car anywhere yet for that reason.

its' just a thought


Arfon

In the back of the car builder solutions catalogue there is a good description of how to cut and stick the trim to these lights. Very easy to do and looks good

If you need any photos of mine give me a shout

I have a snap-off wheel on my sapphire that will probably go on the roadster.

Thanks Arfon yes I've done that but forgot to take a picture.

These are the photos I'm going to have printed for the IVA submission.

Any suggestions? Thanks.

I didn't get a call from the test centre. I had to call them to book my test so I would recommend giving them a call. It will save you a couple of weeks

Oh ok thanks David, I thought you couldn't call the test centres. I'll have to try and dig out the Chadderton test centre number.

It you phone the central number they will put you through. The one thingy tester said is he thought very few people phoned to ask questions prior to the test. (Most likely as there is no direct dial for them).

CTWV50 27th November 2014 10:14 AM

Cheers David, I just got through to Chadderton but no one available to answer questions. I'll wait till the middle of next week and call again. I asked whether they would contact me to book the appointment but she said I would have to keep calling to get my appointment booked. So thanks for the tip I would of been waiting for weeks if I hadn't of known.:)

CTWV50 27th January 2015 11:02 PM

OK I'm officially out of hibernation. Didn't start the car for 2 months and been putting off the IVA x2. Just because weather was crap and I had no interest in the car. Usual kind of thing for me over the winter months. Always end up doing hundreds of miles on my mountain bike when the days get this short and cold. Weird I know but there it is.

Anyway got that out of my system now so I've ended up shortening the handbrake cable 30mm as I had no adjustment and low brake effort. T**t to refit as I 'd shortened it more than I meant to. Relocated that bodged fuse so no worries there. Oh I fixed my bouncing idle and loss of cold start fast idle. I knew it was something I'd done on refitting the engine and shortening the loom but could not figure out what so I was ignoring it. Last night I figured out what it was. I'd left the TEN - GND jumper in the diags port and the diagnostics LED because I THOUGHT IT WOULD BE USEFUL FOR DIAGNOSTICS PURPOSES, how ironic! I had not realised that this had effectively disabled the ecu for ambient idle purposes. Lots of googling and the penny finally dropped. So reset the ambient idle and for good measure as I'd probably knackered the O2 sensor with all the rich idling I swapped it out for a known good one from the 1.8 engine I have. Rock solid idle now.

Oh and I made a coolant bottle to fuse box splash guard out of a tupaware box. just incase I ever overheat and short out my fuses.

Got a car cover on order and thinking of ringing the DVLA to get my date brought forward if possible.

The End.

edit oh and thread locked all the relevant threads that need it.

skov 28th January 2015 08:37 AM

Glad to see you're still alive and well Chris!
IVA x2? Does that mean you've already had IVA x1?

No I haven't been yet, had a date for early Jan which I moved to end of Jan and then I moved that one to end of Feb. Paranoid if I got it legal before spring I'd be to tempted to drive it on damp roads and crash it having never driven a lightweight rear wheel drive car before.

CTWV50 10th February 2015 10:24 AM

So while I'm waiting for the test date the car bug has bit me again so I'm in the middle of a little upgrade project "off" the car. I managed to acquire a rather cheap ashcroft LSD Torsen type differential. Made a cheeky offer on ebay which was accepted.

http://www.mx5nutz.com/forum/index.php?showtopic=102482

I did not really know what I'd let myself in for and I've had a rather steep learning curve and had to buy some new tools to do the job but I had a late mk1 1.8 differential in the shed so I've started stripping it down to clean, paint and replace all the seals. I will be replacing the the side differential bearings but leaving the pinion shaft bearings alone and just replacing the crush tube so I can setup the drag torque once the nose seal is replaced.

I know I could of bought a second hand mx5 Torsen diff off ebay but where's the fun in that and the diff was so cheap it was rude not to buy it.

Here'a a very useful video I found on youtube.

I did the same. Its an ATB identical to a Quaife rather than a torsen, stronger in theory. Bought a diff for it to go in and still ended up cheaper than a used 20 yr old torsen!

Oh I havent fitted it yet so theres nothing on my thread. I just figured 200whp would overcome my 1.6 diff in short order so I better get all the 1.8 bits for the exchange. :D

I just wanted a bit more predictability and traction.

So here are the casing parts and flange all cleaned and painted ready for rebuilding.



I cleaned off the calcification on the aluminium case by immersing it in 18 litres of Tesco "cheapo diabetes rot you teeth coke" (£4.95) and used a fish tank water heater in the hope of aiding the process along.



I could of had it bead blasted but I was interested to see if this worked. :D Took the best part of a week but didn't have to scrub at it at all.

I cleaned up the cast iron with electrolysis which as always worked brilliantly. Just a jet wash and blow dry and it was ready for paint.



I bought a external 7-8" micrometer off ebay and I have calibrated it with a 12" digital micrometer today. I'm following this guide for setup of the new diff side bearings.

CTWV50 13th February 2015 06:20 PM

Domestic Science for me this afternoon.

Take one diff and place in freezer. Unwrap new bearings and rewrap in tinfoil. Place bearings on top shelf of a preheated oven and heat for 1 hour at 250˚C. Remove diff from freezer and drop bearings on to each end using liberal amounts WD40.



CTWV50 13th February 2015 06:21 PM

Try not to burn the table. Oops

You won't notice the bad weather. You will be paying too much attention to every noise squeak and rattle in case something is going to fall off.

Remember to take loads of cable ties etc and electricians tape for the test
Good luck.

I'm trailering it and I'm taking the contents of my garage with me.:cool:

dubzter 16th February 2015 08:45 PM

good luck, when is the big day?

CTWV50 16th February 2015 08:53 PM

Got one of these booked for collection on Sunday. Just as the winds and snow are due!


CTWV50 16th February 2015 08:57 PM

Weather could be difficult on the day.

Hope you are talking about the transporter and not the chrysler :D

skov 17th February 2015 06:50 AM

I hope you drilled some holes in floor, not sure they do IVA's on bathtubs :D
Best of luck mate, not that you'll need it!

flyerncle 17th February 2015 11:45 AM

And they do read forums like this to see what goes on...........:eek:


One tester confirmed this in a conversation about IVA.

CTWV50 18th February 2015 11:49 AM

OMG I hope XCweather is wrong!:eek:



In other news a glued a bit of trim back on that had become detached. And I torqued all the diff ring gear bolts to 80nm with loctite.

edit: At best heavy rain and wind here and at test station, at worst heavy snow and wind. Bollocks to that, I've just phone the IVA station and got my date moved to the 17th March. :mad:
