Hello,

I have a Mitsubishi Lancer Ralliart that's been running on LPI ( Liquid Propane Injection) for about 30,000 miles on the original stock valves. I have an electronic valve lubrication systeem to reduce the heat.

Last week i had a problem with the engine and i lost compression on 1 of my cilinders due to a hole in a stock exhaust valve.

I checked with Ferrea for some stronger valves and it seems they have valves for the EVO X that can handle up to 2400°F .

But are the exhaust Valves of the Ralliart and the Evo the same?

The intake valves have the same partnumber (1010A220).

But the Exhaust valves have a different:

Ralliart exhaust valve: 1011A312

EVO X exhaust valve: 1011A141

Can anybody please tell me why this is a different part number?

Is it cause to the material or do to the dimensions of the valves?

Thanks in advance

 

I can't help with your question but I am extremely interested on how this car runs on LPI and what the power/drivability/mileage is like.

Haven't heard of any Evo/Ralliart running that fuel. Interesting.
