Those who run LPG converted 2.2's

You should be fine. But ideally get a wbo2 and do it right.

[hunker7]

Only thing I will do in near future is remap it, then further power increase won't happen for year or two minimum. Car is my daily, so I don't track it, occasionally drive it a bit harder when on fun roads, but then I will most likely run on petrol anyways. I'll do the normal setup that needs doing after installing new system.

[diesel des]

Prj is correct. But to be fair it would take a bit of doing on a uk road to do that. Get a wbo2 kit.

What's the worse that can happen if I don't use it at the start, and add it later on?

The worst that can happen if you don't set it up properly, is that you melt your engine down.

[doncecone]

No need if you will use LPG to drive the car, not to race it.

[hunker7]

There are probably cheaper ones but I see a wide band kit as an investment. It's vital in any tuned car in my opinion.

Along with a la1 display is what I use.

That makes things much more expensive

It's easy enough with a wideband lambda kit and motronic. As motronic is open loop at wot yiu can trim the fueling so it isn't too rich on gas at high loads buts it's fine in closed loop loads so motronic is happy.

Any recommendation for wideband lambda kit?

Anything richer than lambda 0.9 is a bad idea on LPG.
It's gaseous, so you don't get any more knock resistance. All you get is higher EGT's after the lambda 0.9 point.

Hence why it's a horrible idea to run it without properly mapping on a turbo car, as all petrol cars are mapped to add fuel to keep the EGT's down, and by doing this with LPG you achieve the exact opposite.

This will be problem for me, while I can do all the fitting etc, I have no idea about setting it up etc. I don't know if it's something you could help me with?

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.

Can't wait to get LPG done now. I was thinking, what do people thing of placing LPG injectors under the inlet manifold somewhere, just to make it look cleaner?

[byd1380]

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.

Yeah, Des is correct with my setup here are some pics, the only issue I have is the RS2 injectors maxing out and the LPG having a wobble. Will hopefully head to 440cc's soon. Engine bay could do with a wash
