Hi all

Bit of help please

Can a 2002 ez30 h6 run OK on lpg if flashlube is used to stop valve seat recession

Thanks Chris

All I have ever seen on here about lpg is conflicting reports from people who know someone who had it fitted.

I fitted lpg to my 98 wrx which ran perfectly fine on gas with flashlube. I cant remember how many miles I did on it but it never skipped a beat.

I also converted a bmw 320, a lexus is200 and bmw 330. All of which ran fine.

Thanks for reply

Yea getting a definitive answer is going to be difficult I suspect.

There's at least a couple of members running new age wrxs on LPG as well, but I can't remember their usernames.

Granted the wrx engine is 4 pot, of course, but should give some idea as to suitability.

I seem to recall JGM wrote on pistonheads that he had mapped a couple of cars with LPG as well, with decentish results.

These guys are doing Subaru conversions incl h6, so it's definitely possible: http://www.ozonlpg.com/lpg_conversion_subaru.html

This thread has some decent info as well: https://www.scoobynet.com/showthread.php?t=849493&styleid=26

my03 wrx run on lpg (4 years btw) without flashlube
flshlube is a myth ,no worth a money on 4 pot no idea about h6
it stops nothing just cooling down cylinders but does proper job only on one cylinder
use proper oil and it will be fine

Well if it can be set up to cool number 4 or is it 3 next to the turbo then maybe it is worth it.

What kit did you use?

It is normally aspirated mate

Thanks Henrik

The engine is actually in a vw T25, I installed an ej22 into my last one and was also great. Brilliant engines!!!

I believe t he Flat 6 lums do suffer from vsr. cant find much out about it for t he H6

Yeah i know ,ive been thinking the same, but flashlube works only without turbo spool-air pressure,than there is no sense to fit it.
the only problem ive got - week before and after my battery die(8years old)
it needs 5sec to start engine when switched off on lpg, before I turn it off needs switch on petrol than it starts straight.
i did few longer runs on petrol but it did not help
i would not cry when it pops next year - sti time
i would not fit lpg if i would buy sti instead wrx ppp probably
in the other hand if i could have 350hp on lpg i will do it even for spec c
kit -i know its stag 300 ecu fitted by lpg wales with live warranty
vsr could happen even on petrol, You need to have good map-correct mix lpg to air, thats all.
in H6 its not about vrs, its about valve regulation

There are flashlube systems that don't need vacuum to operate - i.e. they use a small pump to add the flashlube.

ok,lpg operate/burn at about 30-50 degrees more than petrol thats nothing for engine , most important is map-mapper as usual
after 5years with lpg i will say the same im sure- my03 wrx ppp dont need flash lube for lpg kit as it does not work like it should
