Repco one was too small...and at $8 a small square I walked out. Will weetbix (inferior btw to weet a bix) cardboard work? I thought it had to be special impregnated card so fuel wont just soak into it and drip out the bottom?

This was in our diesel hiace.... I pulled it out as I want in in my Viva for old school periodness.. Anyway- it wouldn't work in a diesel would it as a diesel engine has no throttle plate/butterfly thingee- its speed is dictated by how much diesel is injected? Im I right? And my turbo bolted on to the standard (9.5) compression 12A running at low boost- will this help economy? I understand that having 40 more ponies may make me use them more often and use more fuel but if I am just cruising and dont have to rev so hard as the turbo has increased torque (from 110lbft to 150) surely this will help. Is an engine at its most efficient when its at or around peak torque?

oh yeah- heres what I built... No photos of it inplace as I have not mounted inlet manifold back in place. I need a sheet of gasket card - 1mm thick ish. Any recommendations on where to get? needs to be at least 280mm wide.

I'm interested in fuel economy. Must be from my dad who used to run his morris minor about Surrey till it ran out and had little fuel economy notes. He missed my sisters christening- he was taking her to the church (we ain't godly btw!!!- its just what they did back then eh) and the minor ran out of fuel- he actually left her in the back seat while he walked to the nearest farmer for more petrol. good ol' days.... I used to keep all fuel receipts for my Rx3 - on long runs it would get 30mpg which is great. Did a big trip about Belgium and Luxembourg with some very fast driving thrown in and it still did 30mpg. But many people especially rotary owners scoff at my interest in in economy saying things like if you own rotaries that's the last thing you worry about. Fuck them. I like the idea that I can drive a car somewhere on a long trip not break the piggy bank open and then when I want to go fast I can give it a good thrashing on the twisty bits. So I'm interested in economy- especially as fuel has gone up again. On my Viva- it will have the turbo running low boost on a high comp 12A. does that mean that if I just cruise along with out giving it much stick it should be as economical as a normal 12A? I know that old school 70's turbos with really low CR were thirsty. I understand that my rotaries will never be proper economical due to inherent bad combustion from the large surface areas involved cooling the burn. But there is the challenge..

all sorted now- made a steel pipe out of welders bends - simple, cheap, smooth, heavy.. Just need one more little hose join - will use a short section of rad hose.

That is a bloody cool looking wagon!

rad hose it is then! I wasn't going to do the whole section in hose- just two bits at each end of a piece of tube. Tractor place- good idea as plenty of them about here is sunny hicksville.

cool- cheers. Those black ones are ideal....but.... this is the budget build. I'll need two bends I think and its hard to stomach spending $80 on two bits of pipe. It is so easy to access and remove the bends I reckon i'll try rad hose first- maybe take them off every so often to check if they are going cheesy. Trouble is 50mm is quite big hose for a radiator? That evo setup looks like it could have bits that could be bodged to work. I'll try local wreckers and see what bits they have as well. what is the material that OE manufacturers use on cars? is it some blend halfway between silicone and radiator hose material?

I need two 50mm ID 90 degree bends to route my output from the turbo to the inlet manifold. I was thinking I could use radiator hose but as its a fuel charged mix, not just air, this could be a bit dodgy if I had a back fire etc. I went to super cheap (oooohhhhh the shame it it all) but all the silicone hoses are blue- I aint wearing that! I want black. Can I use rad hose? Any ideas? this is the setup..

cheers for that! - i found that picture too- turbosmart? I've built it all now and well happy with it- the Elford WG is almost bang in the middle just after the primarys meet and just before turbo. i think it should be fine but i have allowed for easy fitting of a 38mm wg if needed in future. I actually trust this oldschool flappy style one more than a cheap tial ripoff. like on internal flappy style WGs there isn't really any thing to seize under heat. i'll see how it goes. will post up a photo or two soon.

Nice car and good on ya man for saving it! There is one on retro-rides in the uk that a yound fella is rescuing too- like yours it has suffered a bit with the tinworm. Are they quite rare cars these?

wicked! Now go put it through for a wof just for shits and giggles!

Didn't realise he has already been on here- top bloke anyway. Feet firmly planted.

Wicked car! Is this the first Marina on oldschool? Glad your happy with it. I would just find a spare engine and backyard tinker with it - port the head, see if you can locate a cheap uprated cam from somewhere- that sort of stuff. do it while using the car and then when it ready drop it in. No worries about certing, still use car while building other engine. Do it on the cheap and learn as you go along. This is what most on here do- which is fucking cool in my book. I met this guy who's got lots of marinas when on a walk in Lyttleton. Hes a top bloke- very good to know in your situation. He has thsi run down of his cars- quite funny.... http://kilroy.co.nz/cars.htm

That guy on the youtube clip was breathing a bit too hard for my liking....

Some cars i've had the stabiliser is inside the gauge cluster- have a look. If the car has been sat ages without much fuel in it the variable resistor thing can corrode over. Usually a few good bends sloshing the petrol around and it going up and down can get it working again-in my old triumph i pulled it out of the tank and just very lightly sanded the corrosion off the resistor.

Yeah- right smack bang in the servo/booster. Its fine on an FB as the struts are further apart and enough room. Even on mry old rx3 it wouldn't fit as the engine bay was that bit narrower. Anyway- Ive started the manifold aand it gonna be sweet. Plus I can use my existing WG which is good as this a teeny tiny budget conversion. I wouldnt want to move the master/servo etc as it works well where it is and the clutch master fitted in nice. I'm happy with progress now- though it took bloody ages today to make two flanges outta 10mm plate!! I have the time though...but no money!

sweet. good advice. I might try to use the existing wg first but its fairly baulky. But its there to try...

cool. There's no end float. Just a little wiggle up and down. I.ll put some oil in it and see how it feels. Yeah was going to feed outlet into a small canister above oil line then into sump so no restriction. The whole lot is off a series 2 rx7. Made by elford in england. But its exhaust manifold puts it right into brake master on a viva so making another. Throttle linkage ok. Will start tomorrow on making flanges. How much of an angle can the carb be? 15degrees?

I put the elford turbo assembly in roughly where it will go in my Viva. I'm new to the world of hairdryers so I need some advice. First thing I had to change was the outlet position of the turbo- it now points up and I will have to make a connecting tube from it to the inlet manifold. I can put a hole next to light behind grill as air feed which is handy. There is enough room for a pod type filter. Lots of room behind turbo for exhaust down pipe. Need to plumb in a waste gate in there too. Secondly- the SU carb will be at a slight angle. Does this matter? Are they fussy about that? Will it affect the running- I don't think it should as the float bowl is under the carb but levels shouldn't affect the jet or needle? Anyone know? And lastly- the turbo has a slight amount of play in the shaft. Its about maybe 0.5 mm up and down. Its an old aireserch unit ; type 8317? T3 flange. Its just oil feed to solid bearings. I don't know whether the slack is taken up when it has oil fed under pressure. I'm taking it to a exhaust specialist friend tomorrow to show him but any ideas on how slop there should be? If it needs a rebuild then at this point in time I will just put a carb on and do turbo fit later on. How much do rebuilds cost- ie say new bearings, shaft etc? Do most places that service turbos do the whole lot as a matter of course or can they just do enough? Any to be recommended in top of the south? Is this an old turbo that I will struggle to get parts for?

I never liked these cars much till about 2/3 years ago and they just growing on me. There is a girl who works at local united vid- she rocks round in a standard one complet with tatty bits and rust. I don't think she realises she has is the coolest girl in town. I asked her about it and her dad owns a Viva. Fucking good on him for getting her into old cars- they rule!

You missed the chevette eh- and couldn't bare the boringness of a plastic car. Glad your back. and if it aint broke..modify it. I do like avengers- almost as nice as Vivas...

Cool- good advice! Except Blenheim doesn't have any Audis- most locals still get around via horse- the poorer people ride goats. Would shortening the spring inside not make it stiffer and raise the pressure needed to unseat valve though ? I think for only 5 psi on a weedy little 12a the two bolt jobbies look ok. I might go borrow a friends gas axe and make my own flanges- just tidy them up with a file eh. I used to spend hours on a profile machine as part of my apprenticeship- if only i had the foresight....

Yeah i was thinking it looked in a silly place- plus the gas coming from the rear port would come straight out and hit the gas coming from front port- slow it down/disrupt flow/generally make it unhappy. I sent you a PM walker but I imagine you want a lot more than my budget will allow- this is mega budget viva. I found these last night..adjustable. Any experiences out there with them? http://www.trademe.co.nz/Browse/Listing ... =339238996

Hello, I have this setup on my elford turbo 12a that's going into my HB viva. I'm a newbie when it comes to turbos so some questions.... I will have to make a new manifold to move the turbo forwards to clear the brake servo and master. The WG that is fitted could be moved but apart from the fact its quite bulky I dont know that it is a very good design compared to the new type of poppit WG's. Where would be a good place to buy a external WG, what size and can I buy a flange to suit said WG that I can then weld to my new manifold. What other things do I consider when building the manifold- I have been told to keep the turbo as close as possible to block. Also to site WG as close to centre of manifold- ie just under turbo in centre. The elford as standard runs at 5psi. Are there basic WG's out there that have springs set for that low a pressure? Are there WG's out there that are easily adjustable without a adjustable bleed screw ie maybe some sort of nut adjustment on the diaphragm spring? Can I get a manifold flange for the turbo - its a garret air research T3. Where? Edit:... I found this in a quick search.. http://www.trademe.co.nz/Browse/Listing ... ermanent=0 It seems OK. About as cheap as I expect these things must get? I fully realise that you get what you pay for but I cant imagine one of these working worse than the old cast affair thats bolted to the existing manifold. As long as it opens at 5Psi i'm happy. Advice please. cheers alex
