Cobrascim's SE6A 22 year(so far) project.

Post by cobrascim » Tue Oct 21, 2014 1:56 pm

I should've probably started this years ago but as you will see from my posts I by the time I get my "upgrades" done several years can pass.
I have used my scimitar as my everyday car since around 1992(unless broken/undergoing restoration). I say every day - I go as far as the train station and back everyday for work and we have the family car for normal family duties.
The period of restoration undertaken around the millenium included body off, chassis blasted and galvanised, SS tank and exhausts, front end suspension rebuilt, back end suspension and brakes only - axle painted as axles never go wrong do they?, 2.9 efi stage 2 added with autobox, radiator altered/renewed with fan upgrade, new rear light units, headlamp relay upgrades, body fully repaired and resprayed in lotus yellow with new window rubbers badges etc, new carpets. Interior seats are the only thing not to be touched - so far. Further upgrades undertaken since were fitting of LPG conversion(dual fuel), megasquirt programmable ECU, 5 speed MT75 manual fitted, wilwwod 4 pot brake conversion on front and burr walnut effect dash kit.

Anyway Scimmie has been off the road since last year when the axle bracket went and due to finishing house improvements and being able to use Julie's car( well she calls it her car but I call it the family car-this difference of opinion can be most stressfull!) I hadn't started repair. Over the last few months however I made a jig up using angle bolted to the flat on rear of axle casing(diff cover removed). Brackets now welded on and axle painted ready to go back on. One half shaft assembly fully removed to get in about the seals and the other side used the hub puller pipe flange toll as the half shaft is stuck in. Believe it or not on one side I broke the flange puller and discovered that the full half shaft came out quite easily with the slide hammer. As the axle was on stads i couldn't get the full other half shaft out and instead the hub came off quite easily. I think this axle is female as there is no consistency!
Once the axle is bolted back onto car I shall get more purchase on the slide hammer to remove. I have all the parts to upgrade to a rear disc set up (as per v8church) and I will also be undertaking this mod at this time.

Last night I just made up new straps to fit my focus fuel tank conversion and am awaiting rubber strips to arrive. I have fitted the tank sideways now that the original fill pipe has been cut off. This can be done on the 6A and keeps the tank away from watts linkage. I would have liked to have put the internally curved side to the front to give more room but have it the other way round to allow me an access hole through boot floor to the fuel pump cover. I have the LPG tank behind my rear seats that stopped me getting what would be the best orientation. Just have to blank up old filler hole and provide new filler pipe. Wont use PVC waste pipe as it seems it is made of polypropelene and none of the 2 part putties/glues seem to stick to that stuff. Probably best to use a stainless pipe boded in.

I will update and provide some photos.

Regards.
John.

I did wonder what the extra space in a 6 would give you in terms of the filler pipe - not much you can do in a 5a.

You're right, but I didn't take many pictures during the rebuild and it was done before digital camera days. I scanned a couple of the galvanised chassis and added them to my gallery. The rest of the scimitar photos in there show the car in all its glory. Trouble is now after 14odd years it now needs another respray as the scottish damp winters outside have taken its toll. Now that I have my new dry garage built when I do it again it will have a nice house to be garaged in overnight. Beside the cobra.
I need to go and find how to insert pics into messages like this.

Hi Phil,
Tank straps are aluminium and I've still to work out how to connect into the ford focus pipe connectors on the top of the tank. I have some PA12 pipe but I will probably just use normal injection pipe with jubilee clips. I was going to up the 8mm microbore pipe to 10mm but now that I see the size of the pipe connections on the top of the tank being only around 6mm internal this wont be necessary. 6mm internal pipe must flow enough for a 2.9 - I hope!
John.

I'm using thin wall 8mm nylon and its doing fine (as is the Focus pump) with 212bhp and its still running rich according to the rolling road plots.

Hi Phil,
That's handy to know. I was hoping my car would be up around 200bhp but I need to get it tested sometime.
Being a stage 2 from Specialised I'm hoping it's up in that region although when running it on the standard ecu and vaf meters it would only go to 135bhp.
That was the reason I eventually went to a megasquirt set up.
John.

Finally back together and got it down for an MOT. Axle all freshened up with new brackets bearings seals etc and focus fuel tank.
Failed on rear light problems all pointing to bad earths as usual.
After a search on here decided to do the earth wire mod that several people have carried out. Soldered individual wires onto each bulb holder. Also ran heavy single wire straight from battery to earth points at each side of rear lights joining them together. (used the two outside mount bolts(stainless) for the small outriggers behind the lights just inside the luggage area).
Anyway when I put the hazards on with tail lights on the tails dim slightly on the hazard flash. It makes it look like bad earth but I reckon it is just a strain on the 12v supply. Does this even with the engine running.
Maybe the hazard operation is drawing too much due to age of switch/relay etc. Doesn't do it with the indicator flashing.
Car was laid up so long that the brake light switch was also knackered. Almost got it cleaned and put back together but one of the wee tabs broke. Waiting on new one arriving £2.75 ebay mini one looks identical as used on all the old triumphs etc.

Also as a wee aside. I try to use the scimmie traders as much as possible but when i needed a rear number plate light unit i found it was around £17. So I thought I would have a look at Rimmers and took a chance on the similar looking one for TR2A - TR6 at £7ish. Bought 2 and the screw holes line up perfectly. I know Rimmers will do a lot of business anyway but they should really start listing the parts that are used on the scimitars. Maybe more scims would stay on the road?

As the fuel gauge will no longer work correctly with focus tank fitted I was looking at gauges. My car is lotus yellow nowadays and I was considering freshening up the inside with a new set of yellow faced ETB gauges. Maybe give it a "slightly" :) different look? They even do a clock!
Put the old ones away in a box.

Took my centre exhaust silencers off not long before it went off the road due to one breaking. Straight through pipe was put in both sides and I was getting a lovely deep burble on passenger side but the drivers side baffles were away on rear box so from that one I was getting an old jaguar racing car rasp. Anyway I have fitted the black cherry bombs in place of the centre boxes and retained the rear boxes as is. Getting a nice sound at the moment sitting in the garage. Doing this took a lot of the rasp out drivers side and passenger sounds a wee bit deeper.
I shall find out if it sounds nice when i put it back on the road.

John.

Not sure if you know (yet) but the focus sender values are the same as VDO generic, I think? I have chinese copy VDO gauges in mine - needed a new temp sender for the engine (Demon Tweeks) but they were stupidly cheap.

Hi Phil,
I had read your investigations into the resistance readings and that will be a great help, thanks.
Buying a full set of gauges IS going to be expensive(me being a scotsman) no matter how cheap they are individually.
Stiil tempting to fit a nice new set as a "new" start for me and mi Scim.
Did you stick with black gauge?
Regards.
John.

Have a look on eBay at this ebay link - I've not found a matching clock yet but with the outer bezel removed, they sit quite well in a 5a dash - I expect they'll look as good (if not better) on a 6a. Oil pressure sender was another £15 or so and the fitting is the same thread as the old gauge (just needed an O ring and a bit of ptfe tape - plus an earth connection. Those gauges also don't need an external voltage regulator either.

EDIT: The gauges can be had for less than a tenner each, free post from China - but not all from the same seller... Takes 5 minutes to search for them - but make sure you get the right oil pressure sender to match the gauge!

Crap photo and I've since replaced the dash top with a black one - but the old bayonet profile for the bezel is just visible - if you're looking for it.

Looking good Phil.
