Those who run LPG converted 2.2's

Is anyone here running liquid injection systems?
I'm quite keen on that idea to may away with the vaporiser and avoid splicing in to the coolant lines.
Haven't seen any cars on these systems though but they promising

A quick search and it doesn't seem to be a widely available option this, but does seem very promising

If you search you´ll find some double supports for placing the gasoine and the lpg injector in the same Y support where they both go on each side on the top and the bottom goes where the original gasoline injector was so you don´t have to make a hole in the inlet manifold!

I don´t have them but wished I known before installing mine....lot of less work!

There are other models but this is what I meant!

That is fantastic, would also make it much neater, thanks

you´re welcome!

Pleasure to be helpfull!

Those petrol injector spacer things mess with the petrol injector spray pattern and can cause rough running.

It's worth just emailing one of those supplier's with a list of what you want and to confirm the parts are compatible.

Those magic jet injectors are rated at upto 75 bhp each with the biggest restrictor. I run mine with no restrictions and they seem to be able to match 630 cc petrol injectors easily.


Liquid injection is very promising but the pump always let's the system down.

Also what spec power wise is your car? Lpg kits don't like running properly if your maxing out the petrol injectors your using. So when the petrol injectors system get to 100% the lpg system thinks there is a fault and puts you back on petrol. Happens on rs2 injectors at 350 to 400 bhp.

I was thinking that, as injector would be sitting higher then usual

So what sort of restrictor should I use?

Mine is standard at the moment, will be remapping in coming month, and then start collecting parts for K24-7000 turbo conversion. Just want to make a setup that will be ok with standard power and when I up the power later on.

I would remove the restrictions and try calibrating it in. Should be fine.

Byd1380 on here also has a urs6 on lpg and uses Kme gold and magic jet on a volvo k24 turbo and is at about 350bhp. His only issue is his rs2 injectors being near max and causing issues.

Calibration will be the hard part to me I think. Just got an email back from LPG site and they said the ecu, reducer and injectors are all compatible so good so far. Once I get back to Leeds I want to see what diameter tank I can fit in the spare wheel well and then try finding the tank and appropriate multiValve.

So when I go for more power, I should get injectors that wouldn't be running near 100%?

Didn´t thought of that but it makes sense, instead of spraying into inlet manifold they will be partialy spraying into the adaptor walls!

Yes when upgrading power go for bigger injectors than rs2. 440cc I think is perfect for 350 to 380 bhp.

Also use a wideband lambda kit to help dial it in and don't set it too rich on gas at full power. 12.5:1 is plenty rich enough on lpg.
