12a N/A LPG ??

[metalhead]

The best way with that is if one day they actually make something that replaces the injectors direct and is controlled like the injectors. Don\'t know if that exists yet !

Certainly does, that\'s what I\'m going to be running.  However you need a few injectors as power levels climb because currently they can only support around 80hp per injector (I\'ll be running 6 to start with).  A company over here in WA has been developing an aftermarket computer to run these, and this is the setup I\'ll be running, with the computer controlling spark as well.  The company is \'profire\' but there system still isn\'t available on a large scale, still finishing development on it.  They weren\'t overly keen to send me a setup across the country, so don\'t know whether they\'d be ready to send one overseas yet.  You may find that there\'s a similar setup available over there anyway.

The other option that gets talked about is liquid lpg injection, not sure whether that\'s really available yet though, certainly it isn\'t in Australia due to some legal battle that\'s going on.  

Don\'t know if that helps.  Hopefully there\'s something of worth there.

Right, Update on the never-ending project ! I\'ve sent the vapouriser back to tinley and they have part-ex\'d it on an Impco vapouriser and 300a (350cfm) Carb.

I\'ve rebuilt the spare engine i got off kev without all its innards to use a a dummy engine to work out my carb position and my oil line setup.

Read an interesting thread on ausrotary where the guy had used a bike brake cable to control the oil line throttle and had it working the same as the stock setup. Just need to make some brackets to achieve this !

Does anybody know where i can get jets to plumb the oil lines into the block under the carb ? I think this is done when a different petrol carb is used ??

I need to get some plates cut out to fit the tank in the boot too.

Im seriously thinking of getting as much done myself in the boot and the engine bay. Not installing the filler or the carb, then take it to a local installer and get them to finish off the setup, removing the petrol tank and fitting the gas fill nozzle in the standard filling position. Then get them to do a rough setup on straight gas and then take it to wgt and have it tuned properly.

The plan is slowly taking shape !

This setup should be good for a turbo setup at a later date too

Update on the never ending LPG project.

I have had some clearance issue with the tank in the boot. More things in my head than what actually is possible.

I went to a local LPG installers to have a chat about them finishing off the project with all the stuff I can\'t do. They put my mind to rest and Im going to do as much as possible and they will finish it off. Im aiming to install everything and get them to inspect and tune the setup.

I\'ve made an adapter for the Impco 300a so that it will sit on top of the nikki and use the thottle control and oiling from the original nikki carb.

With the weather better and some more parts designed and lasered out I\'ve installed the Vapouriser into position and plumbed it into the coolant system.

I\'ve still to get somebody else to weld the adapter up (made out of 1/4in aluminium, cut by hand). I\'ve done a trial fit of the carb to get hose lengths sorted and to check that the bonnet closes with the carb in place, which it does . I still need to install some pickups for the vaclines that are plumbed into the original filter.

Some pics:







Im hoping to get the tank installed in the boot next weekend. Gives me 4 days to play then I\'m still not sure on what to do with the filler but will have a proper look during the week.

The car should be dual-fuel too so hopefully will be able to run on petrol until i get the car tuned and checked properly.

The sooner this is done the better

Look what happens when the sun starts shining, lucky we dont live in a very sunny climate. god knows what we could all do...  Very good to see it moving on.   I will have to look at it more closly at the next meet??

[shaunwil]

ok, just tell me when you come, don\'t usually go in the 1st gen !

Sooner I get it done the better ! Save me about 25 quid a week in fuel costs !

Then I\'ll investigate the single turbo option on the 12a

Well I\'ve had some seriously busy 2 days :2Confused

I\'ve removed the fuel tank.
Then cut the boot out.
Drilled the fixing hole positions for my fill-in plate.
Silicon and bolted it all together.
Installed the donut tank into position.
Plumbed the main feed line from the tank to the engine (6mm copper)
Run the level indicator and tank solenoid in to car
Cut a 70mm hole in the body panel next to the filler :2eek
Installed the filler in to position in the body panel.
Installed the Filler pipe between the Filler and the LPG Tank (8mm copper)
Reinstalled the petrol tank into position (needed longer bolts)

Then done a oil change and oil filter that was due too !

Still to install the petrol solenoid, Wire up the electronics & finish off the carb adapter (Vac line placement and a bit of filing).

Then its off to be inspected and certified then off to pips for tuning

Im off to collapse into a heap with possibly a pint !

sounds good ... just need some photos Might want to add some bracing back in after cutting the boot floor out as I seem to recall that the boot floor/wheel well provides quite a bit of strength and stiffness to the chassis at the back, how much have you cut out?

Sounds very interesting though!

[shaunwil]

I\'ve only cut the bolt down point in the car, most of the boot has stayed intack.

Only a little bit of the boot really !

Shaun

[shaunwil]

I didn\'t take any pics while putting it in, but i\'ll post some of the setup once its done.

Shaun

[MikeLMR]

sounds OK then

[shaunwil]

The main outer ring of the wheel well is still in the car, All i\'ve removed is the dimple in the middle. Tank is similar size to spare tyre so didn\'t need to remove a alot. The standard boot carpet looks the same with the tank installed.

Been another busy day !!!

I\'ve filed the adapter to shape,
Install the adapter to the top of the nikki
Jimmy rigged the vac lines (not sure what to do with them at the minute, car runs on petrol and idles ok so should be ok)
Installed the Carb and installed the low pressure gas line
Installed the petrol solenoid control in main fuel line
Wired the controller into car (struggled to find an ignition live)

All I need now is to get it all checked over by a local firm and certified, then book it into pips.

I\'ll post some images once I know its all ok !

Shaun

[shaunwil]

Oh and I\'ve just ordered an alternator relocation kit for the fb from pineapple racing to increase the coverage of the belt on the waterpump without the airpump

Once Im happy with the gas (eventually) I\'ll end up removing the whole of the petrol system. Will investigate whats needed to get rid of as much of the emissions cr*p off the engine and removal all the redundant bits on the carb !

Shaun

sounds like your having a productive weekend.   Where are all the pictures??


Tell me more about the re location kit??
