FrankstaH Posted January 17, 2012 Share Posted January 17, 2012 Hi everyone, I've just put a deposit down on a 2006 Nissan 350z, that has had an LPG conversion. I test drove the vehicle and the LPG has not affect ther performance at all. However, i have a concern... If i wish to modify my car in the future (performance mods) Will the fact that my car is LPG affect the performance mods and the ability to fit them?

Southernspeed Posted January 17, 2012 Share Posted January 17, 2012 Surely it's switchable? So you can run on LPG or petrol ? I personally would be concerned about running an engine like this on LPG due to how hot they can run but I guess they can be mapped to run properly. I'd be inclined to talk to (for example) Mark at Abbey Motorsport about running a multi map system so you can switch to petrol and a performance map then to LPG and a suitable map. These engines seem to (in my limited experience) really suffer consequences from over or under fuelling. Talk to a tuning pro, engines rebuilds are expensive!!

FrankstaH Posted January 17, 2012 Author Share Posted January 17, 2012 It's definately all been done profesionally, I'm buying the car from an approved Nissan dealer. Are there any well known companies that deal with 350z specifically? For example im a former type-r owners... TDI-North / CPL Racing were the most renown ones.

R35LEE Posted January 17, 2012 Share Posted January 17, 2012 Best mod you can do is remove the LPG mate We put a 350z back to standard after the LPG kit destroyed the engine. If your buying from a garage make sure it has a good warranty and check it covers the LPG mod and kit Quote Link to comment Share on other sites More sharing options...

Dblock Posted January 17, 2012 Share Posted January 17, 2012 I would only take it if it's a prins kit. Quote Link to comment Share on other sites More sharing options...
Cragus Posted January 17, 2012 Share Posted January 17, 2012 If you are thinking about trying to mod it for performance gains, I would go for one with the LPG but my knowledge of LPG is very limited. Quote Link to comment Share on other sites More sharing options...
FrankstaH Posted January 18, 2012 Author Share Posted January 18, 2012 You would go for one with lpg conversion, or wouldnt? Regards Quote Link to comment Share on other sites More sharing options...
Neilp Posted January 18, 2012 Share Posted January 18, 2012 He meant wouldn't I think mate. You don't buy a sports car to try and run it cheap. Different with big v8 land rovers etc but with pretty high performance, I wouldn't touch it. Quote Link to comment Share on other sites More sharing options...
R35LEE Posted January 18, 2012 Share Posted January 18, 2012 Agreed, I would walk / run away from that one Quote Link to comment Share on other sites More sharing options...

cally Posted January 18, 2012 Share Posted January 18, 2012 Hi guys just joined just got my 350Z and love her, having looked into LPG one thing is clear you have to way up the fuel savings against the fact that lpg does not have the cooling and soothing ability as fuel does. This means depending on how you use it and the nature of the vehicle depends on how quickly the valves and valve seats errode. Its not a case of if but when all cars are diferent and the lpg use can change depending on user. An oil dropper can be and should be used this can exstend the engine life, switching between fuel and lpg during long trecks also can help. The problem with most oil droppers is they are not load related and they are usally a single point entry so uneven Atomisation. I did look into with a mate of mine at collage doing an engineering degree a design to build a sequential oil droper runing off a map sensor so it could increase as the load of the car increases. we were also going to look at aquamist. If i had a car running lpg i would put an EGT sensor in the leaner exaust run, this would tell you the heat difference between lpg and fuel so confirming the the effectiveness of adding soothing mods you have done. The use of uprated valve and seats also only delay the process to a degree. hope this is of help Quote Link to comment Share on other sites More sharing options...
