I used to have a gas system that used to freeze up and it was cause there wasn't enought coolant in the car......I would re fill it and the converter would like instantly de frost itself......

as GBLOCK said, J30 maxima ...

Nah the thing is it freezes up when i start it in the morning if started on gas, start it on petrol, let it run till it's all nice and warm and then flick it to gas then the converter doesnt freeze up and runs fine..

Checked the coolant, its fine still right up at the top... bled the coolant each time i changed it...

GBLOCK: Yea i'll probably take it there, but unless theres better recommendations for that... From what i've seen good gas guys are relatively hard to come by.. LOL

..I have never had this freezing problem, in 4 years..weird...

Id say ,Just start it on petrol then if that works..I know a few people who do the same..Its good to run some petrol through them anyways...If it doesnt run well on regular use high octane..Works better cause timing is usually advanced on gas..Another trick was pouring hot water (warm tap water will do) on it but thats a hassle..

Wouldnt bother trying to service it as I doubt it would make any difference, must be an old system is it?

Unless maybe the water line is full of corrosion, clean it out maybe

Arthtur T3 - well the gas system is around 4 years old, but has never done this - only recently started doing this... to be more precise when it got cold... yea i always would run it on petrol too - bout a quarter of a tank of petrol to every tank or so of gas and open her up... so i dunno LOL...

STATUS - but how does that affect it at all? if that was the case wouldnt it be like that in summer as well? and if its plumbed in wrong, wouldn't it freeze even after the car is warm and i switch it over from petrol to gas?

the converter is plumbed into the cooling system wrong

Would appear you have seen this before then..

Alot of people have this problem, i thought it was just older systems but 4 years is newer than mine...

So im guessing your onto something :)

So would that mean its not flowing through the convertor before thermostat opens.. Any flow would stop it from freezing and Once engine is warm Id think even the radiant heat would be enough to stop it from freezing..

*goes out in freezing cold to see how gas system is hooked up*

    • @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand
    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
