1989 Lada 'Fiva'

[Cameron]

also bring this to national park if you don't have your fuego sorted by then

[SP450andLE]

clappy tappet's a happy tappet
nice work!
when your bros other one gonna be rolling?

It rolls just fine already!

But to be honest, I have no idea. It got shunted up to the farm when the Fiva came down here so it's less likely that anything will happen to it

[lincooln]

I might do, depends on WoF and if I know if its running all good or not. also need to replace a left CV I think a sits banging a bit. Could just be driveline shudder though. Or the inner CV. Luckily I have about 3 spare inners.

[lincooln]

sweet, well kinda. Lada was taken in for a WoF today. Failed on 4 things. Too much brake pedal travel (which is silly as most Ladas' I have driven have had quite a bit), Uncaptive rear springs, exhaust mounts and bit of rust round the brake master cylinder. Also wanted me to secure front indicator and paint the underneath in chassis black to hide the surface rust.

So far I have cleaned underneath, got rid of the rust by the brake bracket, secured the indicator and started rust converting underneath, Also re bled brakes again just in case. Need to adjust rear brakes again including handbrake, do exhaust mounts, paint and fit standard Lada rear shocks. So by Monday it should be all good to go.

ok just put the timing light in my car (not booger) I am heading up to auckland tonight and if you PM or txt me on 0221920958 then I can organize to come over ad give you a hand timing it up

[lincooln]

ok so it went alright first trip out, well...

It was overfuelling and would not idle, so we lowered the float level a bit and that made a difference, however we have come to the conclusion that the carb is to big and is also overjetted for this application. Also it would stall down hills as webers seem to not like too much of an angle.






So either an injection conversion kit or a 2"SU carb swap is now looking likely, just so its reliable. However the float level change did indeed make a difference on the road.



So now to my current problem, The spark died on it last night while louis was driving. Checked for spark last night and nothing, Fuel yes. So why would it die, its electronic ignition using a coil pack I assume as no coil. Will post a pic soon of the setup so you can tell. I am kinda stumped, checked all the leads, wires to dizzy, rotor, so any help would be awesome,

cheers

I got a nissan motor thats in a niva needs a home..? goes well..

[lincooln]

Really? what motor? but you seem a bit far away

[Big]

Really? what motor? but you seem a bit far away

I'd have to have a look but its a 2 ltr jobbie.. and it has seen some good action off road and from what I have heard from him.. didnt have any major things go wrong.. it'll come with mounts and xfer so I'll check to see if it's unbolt and bolt on.. just to make sure there no worries..

[lincooln]

Sweet as, cheers man

[Cameron]

if it's a DGAV weber you could probably go shitty EA falcon 'single point' injection pretty easily.

32/36 weber should be mint on one of these, aside of the obvious angle issue though.
bike carbs?

[lincooln]

bike carbs be awesome, but room is at a premium. Maybe quad bike carbs up through the bonnet.

Still an SU is easy and cheap compared to most injection kits I have been looking at. Anyone have any ideas on what is best etc?

[Cameron]

dunno. as you said SU would be nice and easy eh.

[lincooln]

Its all back together and working, well kinda, battery is dead at the moment as it needs a long drive / charge as I had to many attempts at starting it.

Hi all

I have a Lada Niva with a 2L Fiat 132 motor and now I am fitting a Fiat 124 injection kit onto it.

I have a few issues that I need help with, so hopefully some of you good buggers can help out.

First up is the fuel rail and how to plumb it up. What are the points 1, 2 and 3? I know 1 and 2 is part of the Fuel pressure regulator, but I done't know which way to plumb it all up,

https://fbcdn-sphotos-d-a.akamaihd.net/ ... 4414_o.jpg

Next is the bit that is on top of the intake manifold that looks like a coolant type thing, What is it and where do I plumb it up to and do I even need it?

https://fbcdn-sphotos-g-a.akamaihd.net/ ... 6086_o.jpg


Thirdly, what do I do here? the dizzy cap cannot fit on with this manifold as the injector part of the manifold gets in the way. Do you guys run a remote dizzy setup or something else? If so, I may be in need of this quite soon.

https://fbcdn-sphotos-c-a.akamaihd.net/ ... 6208_n.jpg

Finally, can the AFM be mounted on top of the engine? or will the vibrations and heat affect it? Sorry for this newbie as question as, it is because I have only had to deal with carbs up until this point.


Any help will be greatly appreciated,

Cheers

first pic: #1 - fuel return to tank
#2 just needs full manifold vacuum, so, plumb where you'd usually get a good vac signal. TBH all it does is make you run a little lower fuel pressure on over run and at high vac. times, i.e maybe at cruise, and idle etc. if you can't find anywhere to hook it in don't worry for now, however if you're using all the bits there'll be somewhere to hook it to.
does #3 hook to the fuel rail as well? is it the fuel inlet or ??? looks weird.

second pic is Throttle body heater stuff. on a 4x4 it may be an advantage, esp if you're going to be running with cold air intake and no 'hot box' type intake thing for winter. there's not really a venturi cooling effect, or a fuel atomisation cooling effect like there are with carbs so you're less likely to have it ice up on you, but, with stock air filter above exhaust on my pug when it was 8v, and a cold air intake and not thorottle body heating it stuck wide open on me at *cough*kph in the middle of the night on the desert road one time. scary stuff. run without it now though and no problems. again, it's not a 4wd with a snorkel, though.
hook it into the heater hoses somehow. if you have all the fiat injected engine piping you'll find a place. tee it into a heater hose (I'd recommend the 'cold' side of the heater hoses to preserve how well your heater goes) if you can't find where they're meant to go and they're the same size. youjust need warm water moving through it. will only ever be an issue (if at all) in winter months, though.
in this these 124 pic it looks like there's provision for it to be piped out of a fitting in the top of the head, and then it buggers off around the back of the engine.

for the dizzy: can you get a more slimline dizzy from a fiat with same engine? run a crank angle sensor type one and an ignition computer type dealio?
will a 124 side entry cap work? can you slam a 124 head on and run the dizzy on the exhaust side like they look like they have?
these guys do electronic ignition dizzys for them that look pretty slimline, and may work. would be stink if you can't get the cap off without taking manifold off, though. lol

what kind of ecu are you going to be running?



on the topic of AFM: pipe it to the inner guard, or at least rubber mount it off the rocker cover. should be ok either way.

[lincooln]

hey man,

I have the original 124 computer, loom and all that.

Dizzy wise the other option is to go for dizzyless ignition, which would be helpful. Kinda expensive though.

I wonder how the 124's run their dizzy? looks like it is off the back of the cam, but can't find any clear pictures etc.

Heater wise I will try to find somewhere to hook it all up. I have no heater inside the can as its been disconnected, but I am sure I can find a place to hook it all up.

Also I have now figured out the fuel plumbing, So I am sorted in that department, thanks.

This thing is like one step forward and two back sometimes.


Bloody Lada

Cheers for the help

[Nivapulledout]

looks like you are on the way to having a sweet smooth running fiat twin cam, good work.

will have to try and bring booger up and go out with you guys some time, looks like you know some nice challenging places. Give me a bell next time you go out and I will see if I can make it.

[lincooln]

Sweet man, will do, Will be awesome to have a line of Lada's, people will tremble in their boots

Now I must head outside and build me some brackets and get some stuff mounted and ready to go.

Then its just the dizzy situation, but I think I will be going for distributor less ignition as its the easiest and best solution.

[lincooln]

So I have a problem with the wiring I can't get my head around.

It is this part:



So do the bits that lead to the ignition switch just mean a 12V power source? They are all one in the same?

Link to the original picture is here which gives more info: http://www.artigue.com/fiatcontent/Wiring_1980_1982.pdf

Any help appreciated, I hate wiring diagrams.

[Mattman]

Ignition switch usually means a 12v source that's live with the ignition on. In the bottom pic you have one feed that goes direct to the battery so is live all the time whereas the others are switched.

You might want to consider using a relay to supply the switched circuits. Trigger the relay from the ignition. Probably won't be a big draw but best not to have it come directly thru the ignition barrel.

Matt.

[lincooln]

I was thinking of just having it switched by a switch on the dash anyway. as its easier than trying to work out the Lada wiring. New wires are better wires.

So its means then that I can then just have a switched 12V source for the ones that run off the ignition switch, which makes things simpler too.

[lincooln]

Also, pics of the Fuel pump and the surge tank mounted up.

[lincooln]

So this update may have some old info in it but oh well. And also pics will come soon. My current phone just shat it self and my camera has been stolen so I am camera less at the moment.

Came upon one major problem which was that it couldn't run the standard dizzy setup with the EFI manifold as the injectors got in the way. So I found a kit online that is a dizzyless ignition system. It is a Compu-Tronix unit and works on Fiats and Fords. Sweet kit with everything in it from leads to wiring harness etc. Spark is meant to be 50x stronger than a conventional setup so yay. Looks sweet with a coil pack now too. The computer and all the wizardry fits in the thing that looks kinda like the old dizzy and it bolts straight in. Can't say enough about this kit.

Had a few problems with the EFI kit, missing the double relay, and numerous other bits. Got it all sorted though.

Went to start it and the original fuel pump seized so had to buy a new one, got a 044. Much better now. Also had to by pass the surge tank as it wasn't working right as the lift pump could not keep up with the 044 so currently to get it running it is now sucking straight from tank with return to tank. To set it up right I kinda need a four port surge tank (return to surge, lift to surge, EFI pump feed and overflow/pressure relief to tank) so that's annoying. Will see how this way goes for now.

Filled the cab with fuel as I had hooked up the fuel return line in the engine bay but didn't check the tank connection as I was lazy and it wasn't there. So filled it all up. Typical. Sorted that issue and it was much better. After a month of leaving it open to get rid of the fuel smell.

Finally got it running on Saturday. Main problem I think was that the throttle position sensor needed to be re-calibrated so I did that and it fired up straight away. Have run it a few times now but at the moment it won't start again, re did timing, reset the TPS again and new plugs too. No luck. Can't work it out. Battery is now being re-charged so will see if that helps. I wanted to get it going again so that I could get it for a drive and clear it out. It had old fuel but I have drained that and refilled with good 98 too, which will help the plugs fouling up.

Sounds cool and seems way smoother and a lot happier to rev now than it used to be with the carb setup. Looking forward to getting out in the mud. I just need to tidy up some wiring, change the oil,

I have now driven it twice. Today and yesterday. It is still fowling up plugs but I am pretty sure that is down to incorrect timing and the lambda sensor is no doubt carboned up as well. But it runs well, just doesn't like to idle.

thinks that's the main gist of it all.
