Hi guys,

I'm looking at switching back to a C34 stagea and converting to LPG. (see my sig - the M35 is for sale. I'd convert it to gas but just dont have the funds...hence i'm looking at going back to a series 2 c34 and using the extra cash difference to pay for the LPG conversion)

Wondering if anyone can recommend a LPG conversion place that specialises in this sort of thing or at least would be competant (and willing)?

Looking at getting a SVI system if I can. Any idea of cost as well? i'm thinking somewhere around $4k, or $2500 after rebate.

yup GWW on marion road had a mamoth xr6t result on gas.

Id go there but get a written quote from brett west and pay not 1cent more

- still stinging tho 4.5yrs later after being hugely OVERcharged for a 100,000km service where waterpump wasnt replaced (went 'poof' not long after)

I'll never go back tho

Classic Performance Dyno at Hackham specialises in gas installations and tuneups.

He's got an old 70's Holden with a full V8 Infiniti conversion running straight gas making 190rwkw so he seems up to scratch with it all.

I'm taking my Subaru Outback there to get a gas conversion done soon.

Nothing wrong with LPG my friend.

Trouble is finding a good tuner for the LPG & getting the right setup.

Graham West comes to mind also when in reguards to LPG setups.

Very true - the detail is in the system and the installer/tuner. the right combination of these should give good results.

I should be clear, I'm not doing this for performance...it'll be a family wagon and for the most part will remain stock. I'm looking for a wagon that's going to be fairly low cost to own, and the choice came down to a LPG falcon (BF) or LPG stagea. I'm fully aware of the extra cost associated with an import (have owned 2 stageas now and 2 other imports before that) but in reality, other than repairs, the difference is pretty negligible - something like $10 a week or so. As far as repairs go, we've had a fantastic run with both stageas. Falcons aren't too bad these days reliability-wise but it can be a bit of a lottery...whereas stageas do seem to be more reliable on average.

The idea is, I can sell the M35, buy a C34, convert it go LPG (+ get $1500 rebate), and still have some money spare for other things. Its about lowering our costs without severely impacting our lifestyle, hence the preference for sticking with a stagea. We've owned a C34 before and reckon its worth doing, considering the fuel savings, and the fact that this is all possible using money from the sale of the M35.

Just wanted to make sure it is feasible as far as getting the work done professionally in SA, before I jump in and buy another stagea.

yup, had a v8 soarer with a mild tune showing some reasonable improvements too. the only downside is cost, straight gas injection cost a reasonable amount of coin.

You don't have to go straight gas conversion though, keeping petrol has it's benefits. The system I use on my work ute actually starts and runs on petrol then automatically flicks over to gas when the car is warm.

There are two main hassles people have with LPG and petrol both being operational.

One is that petrol runs richer on a cold start whereas gas doesn't need to. Gas uses a piggy back computer to intercept the signal the ecu gives to the fuel system to tell it how much fuel to run, hence it puts more in when the car's cold and overfuels when it doesn't need it. (This can also be overcome by running on petrol initially).

The other is that a lot of cut cost tuners just upload a rough tune, get it right at about 3000 rpm with the gas analyzer in the exhaust pipe and the rest is estimated which can result in poor idle, poor power and poor economy.

Both problems are not problems when the tune is done right.

lol

you DONT want dual fuel unless you can find someone to tune it properly, otherwise it'll be inefficient on one fuel or the other (it is possible to get the best out of both). Straight LPG injection is the way to go IMO. Above mentioned workshops obviously know their stuff if they can apply it to most EFI vehicles with ease. I was looking into this a few years back on my RB20DET R31..........cost was too high back 4 years ago, no doubt more affordable now though

im saving for the diesel/gas conversion for the patrol, to make it run cleaner

Thanks everyone for the responses.

I am looking at going dual fuel, and therefore I want a SVI system so that it has the separate piggyback ecu for the gas. This way it will have a different tune for petrol vs gas and should get the best results. The tune is important so I'm hoping wherever I choose to take it is good with tuning as well as competant with the installation.

Whilst I'm not chasing big power or anything, I would like it as close to the performance on petrol as possible, but will need to see how I go.

At the end of the day - I need to sell my M35 first...but good to know the options I have.

      The R32 suffers from an instrument binnacle that is uncomfortably close to the design of a VN Commodore's. But beyond that, the layout of the rest of everything, and the materials (ie the vinyl coverings on dash, armrest, etc) are acceptable, and the patterns on the fabrics are not as blergh as those in the R33. And R33 seats are....quite unattractive. I know it's only small details there, but I reckon the R33 got worse than the 32. But the big blergh is the overall shape of the dash on the R33. It's just has that whole Maxima/Pulsar sort of look to it. Nothing special at all. Generic Nissan sedan. Whereas, at least the R32 dash/binnacle was different. Less a wide expanse of boringly curved plastic. More a "cockpit" sort of look, even if nowhere near to the degree that the A90 Supras got. R34 seats look good on their own, until you realise that they are indistinguishable from the shape and fabric on 70 other Japanese cars. And the foam bolsters on them suffer even worse than the earlier cars. Other than that I don't really have an opinion the rest of the R34 interior. I took the bits of the R34 I wanted (brakes and engine) and added them to the best external appearance Skyline in the modern era (the 32). So nyerr!

      Can I be your first customer? I would like hard lines done for the fuel system, 8AN up and 8AN back and the underside wire wheeled and coated (brush or sprayed) with that black tar shit.

      Speak for yourself, I love the R33 interior. 32 is blergh. I like the 34 interior too. Then you start getting much newer in most cars and they all turn back to blergh. 😛

      500-600hp into a RB is already 'sinking endless amounts of money' into an engine. Especially a 30 year old engine. Unfortunately this is the RB Game. Considering stock power (or at least stock components) will do ~360whp on 98 by simply turning up the boost on the stock gear on a RB26, that would be where I'd say the cutoff point for "sinking endless amounts of money into the engine" Cause to even do this reliably you'd probably need to replace all the bits anyway cause they're old, starting your sinking journey anyway. I reckon the least painful way is rebuilding the engine to make 50hp over stock lol. The 'plan your ownership around a rebuild' was a common saying 15 years ago.
