Tricky-Ricky Posted January 1, 2010 Share Posted January 1, 2010 Just wondering other than the obvious suspension and ECU differences, are there any others to bare in mind when looking with a view to buying? I presume the import will require 98-99 RON fuel and the UK can cope with 95 RON fine? and i also presume the import will be more expensive to insure, average costs for insurance or a link would be helpful Quote Link to comment Share on other sites More sharing options...
captain Posted January 1, 2010 Share Posted January 1, 2010 Look on the FAQ on the JDM sub-forum. It's ALL there. Quote Link to comment Share on other sites More sharing options...
chris84 Posted January 2, 2010 Share Posted January 2, 2010 UK can cope on 95RON but my understanding from reading the manual many months ago was that they don't recommend it and if you have to they suggest mixing with 98+RON 50/50. Even then you shouldn't give it much POWER. Quote Link to comment Share on other sites More sharing options...
sunset350z Posted January 2, 2010 Share Posted January 2, 2010 Don't put anything less than 98 ron in your car. Its a sports car with a big engine, so don't compromise. The biggest and obvious difference is no cruise or bluetooth, which means no buttons on the steering wheel. Quote Link to comment Share on other sites More sharing options...

Sarnie Posted January 2, 2010 Share Posted January 2, 2010 I used to put 95 ron stuff in the Gallardo too You might lose a few horses but your not gonna notice it one bit unless your on a track or a dyno...... Quote Link to comment Share on other sites More sharing options...
IanS16 Posted January 2, 2010 Share Posted January 2, 2010 I haven't noticed any power differences with any fuels but I definitely get a lot more mpg from tesco 99 ron. plus its only a couple of pennys more so you might as well use it just to be safe.

nixy Posted January 2, 2010 Share Posted January 2, 2010 funny thing is i HAVE noticed a few MPG difference with BP ultimate but NOT with tesco 99...........odd. I do alternate but that's more to do with my paranoia. I'm sure boggo is just fine. Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted January 2, 2010 Author Share Posted January 2, 2010 The reason i remarked on the UK and fuel is due to it having widband lambda, and so should have no problems with lower grade petrol unlike the import which will be mapped for 100 RON. I also agree with the comments about BP ultimate, i have noticed better fuel figures even with my Supra So far from reading and comments i have gleaned that although the JDM model is in basic form less speced than the UK, however as with most Japanese import cars, they can come in almost any trim level that the UK can, and sometimes some nice things that the UKs don't.

zedwagon Posted January 2, 2010 Share Posted January 2, 2010 I put optimax in my import for the first few months but then switched to 95 pretty much all the time as I found I got better mpg with the 95. It also felt better with 95 in rush hour traffic. You're right about the spec-it depends which one you go for. St is the highest and basically the same as gt but no cruise, but you can get some nice extras such as auto folding mirrors Quote Link to comment Share on other sites More sharing options...

St is the highest and basically the same as gt but no cruise, but you can get some nice extras such as auto folding mirrors I imagine that the ECU in the import is capable of switching maps if it is continually fed with 95 RON, it will just keep pulling timing until its forced to use a default map by the det sensors going all the time. It probably will feel better in slow stop start traffic because it will be running retarded ignition timing, but it will not do much for the high RPM band.

Car will self learn the ignition your see around -30 bhp on a dyno run running 95 octane. Mapped a few cars to run on 95 octane thou , they run around 260ish bhp after setting up.

I'm not trying to be clever but I just wondered if that's the reason why we daily drivers don't notice an appreciable difference with the higher octane fuel.

janz70 Posted January 3, 2010 Share Posted January 3, 2010 you will find all your answers and more in the JDM (Japanese Domestic Market) section but you car will run on 95 fine (ignition will self adjust) the suspension is stiffer then the uk counterparts I believe (harsher ride but better handling) the fuel tank is a lot larger on the JDMs. Insurance will cost a little more than the UK versions but not much - look at Bell insurance (easy tick box quote) being an import most insurers dont like them although 99% of car indentical - infact JDM version limited to 112 mph (as are all jap cars) but this is removed when its converted to read mph during your SVA. Also look out for when the car was registered (imported) into the UK - needs to be before 2006 to get cheaper road fund licence (dont know exact date ) Quote Link to comment Share on other sites More sharing options...

Edited: Thats i bit pricey, you can buy a converter/delimiter from Thor in the UK for about £100 (there are some cheaper versions) also most importers that sell in the UK will have already put the car through an SVA and delimited the car before offering for sale.

I'm not trying to be clever but I just wondered if that's the reason why we daily drivers don't notice an appreciable difference with the higher octane fuel. As BHP is calculated through torque produced, any drop in BHP will inevitably be due to a drop in torque, however at lower RPM it will not be as noticeable due to the larger motors higher reciprocating mass etc, if it was a 1.6 or 2lt it would be much more noticeable.

Sorry was thinking of Supra wen i mentioned Thor for delimiter, but there are much cheaper delimiters available, edited my other post now, what i meant was that most importers will have also delimited the car as well as SVAing before sale in the UK.

Sarnie Posted January 3, 2010 Share Posted January 3, 2010 I'd check any import for a delimiter as there have been sooooo many people coming on here with limited JDMs wondering why they can't get over 112mph, which patently haven't been delimited when sva'd Quote Link to comment Share on other sites More sharing options...
