Has it been done? serious conversation we had at the weekend , regarding building a Transit Cosworth to run on LPG and make it economical, as a business vehicle.

JonnyBravo

No reason why it cannot be done, I'm a LPG installer and although we have not converted a cosworth we haev converted many other forced induction vehicles.

Certainly won't have any troubles finding somewhere to put a HUGE gas cylinder in the back.

Need any more advice or info PM me mate

tabetha

It has been done on at least three different ones, and I am about to do another!!
Using a TARTARININ TECH 97, or may go WET INJECTION, have not decided yet.
tabetha
ps loads more torque than petrol, like 30/40lb ft more!!

JonnyBravo

How advanced is the Tartarini ecu then ? I use the Prins or BRC systems and the prins would probably be useless, the BRC however may well have the capability to do the job.

Doesn't LPG have a higher octaine rating? 104 ron??

banhambuilt

i have a zavoli system on the bm,and it preforms faultless
not tried any other system yet,although my other 540 will need a system fitting soon (10mpg around town )

jonny
you had much experience with the bm`s plastic inlet manifolds,i have heard not many systems injectors will fit it?

dave

JonnyBravo

lpg does have a higher octane rating, wether its 104 or not I don't know.

Never had a problem with fitting injector jets into BMW manifolds mate, only one to watch out for is the ones with the air bypass as sometimes you need to fit a dip tube in the manifold which then injects the gas closer to the valves to avoid any idling issues.

We dont use Zavoli but drop me a PM if you need a quote on the systems we use

Deffo been done,

Phil Price runs all his rally cars (rally school) on LPG inc all the Escort Cosworths

JonnyBravo

You sure about that ? My boss done a day there and I would of thought he would of mentioned that to me ?

I REALLY want to go and do a day rally training with him, supposed to be excellent

rstoughy

iTrader: (5)

Definitely,

Done the day myself and asked what the big gas cylinder in the back of the car was Also in true cossie style the Escort broke down so i managed a sneeky look under the bonnet just to confirm

P.S. the day WAS excellent

JonnyBravo

Cool, I'll have to get a day over there sometime this year.

Cheers for that info

LPG is 118 OCTANE, I was running 56 degrees(total)advance last 4i I did, it was way better on gas than petrol, much faster quieter smoother.
You do not even have to have a tank in the boot, use the spare wheel well for a donut tank.

one thing that hast ben mentioned is that lpg has alower calorific value than petrol, hance more gas is consumed compared to the equivilant in petrol to get the same burn,
i fitted a kit to my old van (rover V8) was well worth it, was much smoother and at the cost of it you can allow for a differant burn rate, made the van very usable rather than expensive, makes my diesel van (110hp) seam shit now , so much so its going for a remap tomorrow !

Rhys

Way the Civic is going will be getting LPG conversion

JonnyBravo

Trust me, don't do it to a Honda

Rhys

lol, how come?


I would'nt anyway just joking.

JonnyBravo

That will teach you to go from a Derv to a rev happy Honda !

Hondas tend not to like LPG much, we strictly wont touch them due to the valve seats falling apart.

i had a transit with a lpg conversion from new for ford by tickford
it was supposed to be a great idea , get a tranny with a ford lpg conversion
,exept for the fact it was poo
i even chased down one from the same fleet still owned by ford on
lease to ADSHEL, and the driver said they were mint on unleaded
but on lpg they were fcukin useless, i had to take mine back to
fords lpg factory in coventry(now prodrive) as i wanted it proper
and they told me even working they stutter and don't drive great
on gas,good luck with a cosworth powered lpg conversion.
btw, john goff who owns shropshire rally school(and other rally schools) has rally cars on lpg

JonnyBravo

The Tickford liquid injection conversions were nothing but trouble.

Vehicles like that with what you would consider a good company to have done the conversion is what gives LPG a bad reputation.

cozzfather

iTrader: (1)

NOTHING BUT TROUBLE!

the bleeding thing blew the air filter to smithereens,when i found i could
not buy the top of the air filter from fords, i plastic welded it(and did a
nice job too,it took half an hour ) and then almost straight away the fcukin thing did it again

JonnyBravo

Hit a nerve there mate

you will be amazed

big_wig_074

ANY honda?as my dad has a crv he was thinking of doing.ill advise hime otherwise if its a bad idea.

JonnyBravo

Tell me about it I have saved a fortune since converting my car



I'll find out on the Honda CRV if you want

big_wig_074

if you could please mate,itd be a great help as hes thinking of selling his motorbike to fund it!

Benni

Can you convert a diesel? Not going to or anything just wonderd? lol.

big_wig_074

apparentlt lpg is like nitrous to diesels,have heard of lorries using it!

JonnyBravo

I have heard they do use it on Lorrys as it gives a load of extra torque, no doubt it would damage the engine over time which I presume is why its not common

robrs2

I was thinking of getting my Skyline done. Do the systems require extra injectors fitted?

JonnyBravo

Yes, the original injectors are left in place and jets and remote lpg injectors are fitted.

The vehicle remains Dual Fuel so you have the option to run it on either fuels if required, the car wont start change onto gas till the water temp is approx 40 degrees

robrs2

I see. Do they get screwed into the manifold or how do the fit in and where

JonnyBravo

The manifold is drilled to fit 6mm jets, the injectors are mounted on pipes as close as possible.

Drop me a PM mate if you need any more info

robrs2

What is the rough cost of an installation

Garage19

And the best bit of an LPG conversion.......

You can throw your CAT away as you won't need it at MOT time anymore.

banhambuilt

all depends on the make really
there are basic systems and there are all the bells and whistles ones.

i have a zavoli all singing all dancing 1 on the 540 and it preforms faultlessly,i have just been in talks with the firm that fitted it to also convert my 540 touring (estate)
as a rough quote it`s gonna cost about £1900 (depending on tank)
there is a few to consider (single or 4 bolt hole,spare wheel well ones or proper tanks)

it ain`t cheap but you gotta ask yourself how long you are going to keep the car,it`s present mpg.
my 540 estate does 10 mpg around town roughly 24-28 on a run

Cozzfather... LPG stuff has moved on a bit since then. The airbox exploding would have been because of the crappy ring mixers they used in the inlet pipes.

Surely you could mount a couple under neath in a transit?

Also, cleaner oil at oil changes, less shit around valves, head etc. Now the systems have developed over the last few years, LPG is becoming a really good alternative. Theres also masses of filling stations now, as opposed to when I had it.

tabetha

LPG does not have to be injected depends on system, but wet injection better.
If you use BUTANE instead of PROPANE it has a CALORIFIC VALUE OF MJ/m3 DRY of 121.8 as opposed to 93.1 for propane, so this offsets it a bit.
