high octane fuels contain high concentrates of internal engine cleaning additives... a clean engine will idle better, will burn cleaner, will burn effectively which = a bit more mpg, high octane will also restore lost engine power and in some cases will give a bit more power in high compression ratio cars or turbo charged cars. and I have just received vouchers from Shell today which includes £5.50 off any fillup. thats almost a gallon of free fuel from Shell i recon its better than super markets spend £50 on food shopping and get 1p off a litre of fuel. :winky: personally V power gives me smoothness when driving, engine extracts a bit more mpg and I have my ECT PWR activated all the time, and i get to fill up 1 gallon for free every now and again..its a win for me.

hi mate he normally does not put everything hes breaking on line hence he put his contact number aswell so just give him a quick buzz and ask if he has the part you looking for to break and if he does, you are a winner :) . off topic but why do you need this part off the IS300 if you have an IS200?

Hi mate get in contact with Ricky he breaks IS's and helped me out with my wing mirror. he can sort you out with any part you need off an IS200/300. might be able to post the intake scoop over to you for a small fee. http://www.ebay.co.uk/itm/lexus-is300-wiper-blade-breaking-parts-spares-not-is200-/300863407950?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item460cdb474e

servicing at JEM lexus is £119.99 for interim and full service is £219.99. havent used thier services before but they based in London and have runing the garage since 1975 so must be doing something right. I tend to buy my filter and oil and take it to my trusted garage near me to do the oil change for £30 labour. all works out just around £80 in total service book dont get stamped but i keep all purchase reciepts for proof of work done if and when i come to sell it on. http://www.jemlexus.co.uk/servicingQuote.php

depends on where you drive and how you drive mate. e.g. when i fill up £30 from a when the fuel light comes on using V power and i drive say 60% town and 40% open road, i get around 75-85miles from it. but when i fill up the same £30 and head on the motorway and set cruise control at 70mph the same £30 will cover 145-150miles before the light comes on again. good mpg also depends on the engines health and quality of fuel being used. some fuels will burn quicker others will burn slower all depends on the extra additives added after they come from the same refinery. and one thing others miss is this is not a 2.0 litre 4 cylinder engine but saying that i constantly get 33mpg on a long constant motorway drive with cruise control.

ahh that explains it then, most people get confused when they hear valve mistaking it to meant the engines intake valve. whilst forgetting the ACIS also has a valve which opens. so correct me if am wrong but are you not loosing even more low down torque by having the ACIS valave open all the time?? i was under the impression when this valve is closed at lower revs i.e from say 750rpm to 3500rpm it helps build up cylinder pressure becuse the air comming in is going through the long route in the tube which will mean more air because its taking the longer path to speed up the cylinder build process and once 3500rpm is reached the cylinder are charged up enough with air so the longer path is not needed and thats when the shorter path takes over by the valve opening up to inhale that rush of air. and i think it makes sense for Lexus to have it this way because lots of air is not needed at lower revs cylinder pressure is whats needed at lower revs and lots of air is rather needed at high revs. so by opening it 24/7 i beleive your low end torque will de affected drastically which will result in you even putting your foot further down to gain any speed at low revs but i might be wrong.

sorry mate.. NM is just a torque figure it can also be listed in lbft(pound foot) if you understand lb ft better??. the higher NM a car has the better it can pull at lower revs. the IS200 has 196NM in total so it will pull better at lower revs compared to another car with say 100NM of torque. yes VVTi does not kick in or activate. becuase its already on from 750rpm to 6200rpm. the kick is the ACIS opening a shorter intake path to speed up the air entering into the cylinder. intake path/port is the tube which the air coming in travels through. and itake valves are those little rods which moves up and down as seen in the vid i posted up. so yes VVTi is the valves opening on either the intake side or exhaust side to give better breathing which results in better acceleration. valves cannot stay open at all times becuase they need to close at some point to allow the engine to combust the air/fuel mixture. Hi Disco stu can you please send me the link of how the dude managed to get his intake valves to open all the time?? its impossible to have intake valves open continusly during and engines operation because in order to have a combustion process, intake and exhaust valves need to close for this to happen. this process is known as the 'power stroke' this is where both the intake and exhasut valves needs to close so the spark plug can ignite the air and fuel mixed inside the cylinder.

yes Chris not lift per say as lift technology is only in the Celica VVTLi but what you get is a broader torque delivery. so depending on how far Lexus has set the IS200's cam phase duration to operate, if your car needs e.g. 170NM of torque at 3000rpm when you instantly floor it for more power, it can program itself on the fly to achieve it or if it needs only 100NM of torque at the same 3000rpm when you just cruising for a bit of economy, it can program itsself on the fly to achieve it. hence toyota added the 'i' which makes it an intelligent engine. VVTi engines use one cam lobe. hondas VTEC uses two different cam lobes. cam lobe is like the metal piece which beats on the valve head causing it to move downwards to allow air into the cylinder. so honda VTEC's are not intelligent but more 'wilder' the reason why its not called intelligent is because its set to activate at a specific rpm so one (smaller) cam lobe operates within say 700rpm to say 5900rpm which gives it economy and the other more(larger) cam lode is set to activate at 6000rpm to 8000rpm which gives power. the larger cam lobe will beat down on the intake valves more aggresively causing the intake valves to travel down further. travel down further and more air gets into the cylinder. more air at high rpm = more power thats why honda can achieve 200-225bhp from thier Civic and Integra Type R's without a Turbo charger becuase he air being drawn into the cylinders using the VTEC technology at high rpm makes having a Turbo redundant plus no Turbo lag is experienced. VVTi's valves does not travel down further in other words it does not 'Lift' to allow more air. the valve lift is set at one specific angle and cannot be altered like VTEC becuase the engine doe not have that bigger or wilder cam lobe to beat down the valves agressivley but what it can so is the 'phasing'. which means the one cam lobe in the VVTi can move forwards or backwards. am not sure but one position is for advance which causes the cam lobe to beat on the valve ealier an early beat will result in an early open to allow more air. and as rpm is increasing, so is the phase of the cam adjusting itself working out the best fuel/air misture needed for more power or economy through out the rev range. below is a little video a bit boring but gives you the idea.

You 100% right Disco stu VVTi is nothing like Honda VTEC and does not kick in at a certain rpm. am surprised most guys in the previous posts where going on about it kicking in. VVTi is always on i.e the engine is always on 'cam' and it advances or retards the phase of the cam for best performance or economy based on pedal position and other factors. the kick whcich is felt is known as Acoustic induction control System, it just lets in more air by opening secondary intake manifold ports once a certian rpm is reached and that surge in of air gives that 'kick' effect. http://www.lexus.com...odel=All#active in a nut shell VVTi works by altering the time or duration the intake valves open, i.e either earlier or later and VTEC works by altering how far or low down the intake valves travel when it kicks in. they both achieve preety much the same goal. if VVTi cam advances and opens earlier and closes late, then more air will be sucked into the cyliders..if VTEC causes the cam to to travel down further at a high rpm, then more air will be sucked into the cylinders becuse the valve is travelling down further or staying down further than it should. by the valves travelling further down and coming up is called the 'Lift'.. VVTi does not lift.. VVTi helps build more tourqe in any rpm and VTEC helps build more torque in just high rpms hence VTEC's can rev to 8-9000rpm. Toyota VVTi is Hondas iVTEC = cam duration phasing Toyota VVTLi is Honda's VTEC = cam lobe changing

1JZ-GTE or 2JZ-GTE supra engines are best . the IS200's gear box cannot take the torque those engines chuck out. so if you want a manaul then V160 Toyota/Getrag gearbox or W55,W58 manual depending on what power you looking for or A650E automatic box which is already in the IS300 handles 400bhp with a transmission cooler and valve body upgrade. most guys in US are also fitting the V8 GS430 engines into the IS chasis. drop in that V8 engine and thats cheap,easy, reliable 300-310bhp on tap with A650E gearbox but thats not saying both 1JZ and 2JZ's are not reliable. worth asking the guys on the US forumns as they play around with Turbo/V8 swaps than us in UK. http://my.is/forums/...e-is300-294993/ http://my.is/forums/...-blower-287373/

I believe IS200's dont have MAF sensors so K&N will be ok..I stayed away from the oiled filters due to the possibilty of oil coating the MAF sensor causing it to mulfunction in the long run. both brands are established well known brands in motorsports K&N american, Apex'i Japanese tuner..so both companies have the know how to make a good air filter.. depending on engine health and engine type, one can extract 5-10bhp from an NA engine and 10-20bhp from a Turbo engine from a performance filter with other modifications to accompany of course.

http://www.ebay.co.uk/itm/1999-LEXUS-IS200-SE-SILVER-/121069716900?pt=Automobiles_UK&hash=item1c305145a4 there is a 99 model with 172K on the clock no rust on body work, paint is still looking good. a good interior valet will restore it back to the way it looked in 99, this car will do another 30K easily to take it to 200K. so my guess will be Lexus designed these to last for a minimum of 20 years or 300K easily if the most important fluids are changed religiously when they due.

I was under the impression this level of sludge build up should never occur If the dealer was using the recommended 5W-30 fully synthetic with the oil being changed every 12 months or 10,000 miles regardless of town or stop/start driving??..engine looks like it has never had an oil change done before based on the pics.. l am not pointing fingers but looks like the dealer might have been topping up the oil rather than doing a full oil change for this level of sludge to occur.. although this might not have contributed to this sludge build up, thats why i stay away from Supermarket fuels no matter how good people say they are, I use branded 5W-30 engine oils i can afford which includes cleaning additives, and run my car on high octane fuel for a whole month every now and again which also includes high concentrate levels of internal cleaning additives. tho some might say its a waste of money, i say it helps prevent these things from occuring which = money saved on engine repairs in the long run...

OMG... What type of oil were they using to service your car?? thats why i always buy my oil and filter take it to a trusted garage and stay they watch them do the oil change. I never leave my car at a garage and leave them to do the work..sad to say but i dont trust garages any more hence i stay there and watch them do the job no matter how small a job it is.. hope it gets sorted..

Haha dont we all? :) .. Yeh had an eye for the MG-ZT's but was not convinced about them resolving the headgasket issues so bypassed it and went for the ford Cougar 2.5 V6 then.. but the MG-ZT is a nice looking motor.. if only thier engines were as bullet proof i would...

Thats a steal right there craiglancs.. intake tube is Aluminium and comes already bored with hole to house the MAF sensor so all you need is a better cone to go with it... AEM, Blitz, Apexi, K&N all do the job well but lean towards dry type filters to save your MAF in the long run... and get a heat sheild aswell to protect the cone and if you lucky 5-10 horses could be extracted from the engine. dont forget to do an ECU reset... :)

am with Stuart on this...must admit i do have a flirty eye for pure American muscle cars the Dodge Chargers/Challengers , Shelby Ford GT 40's, and th Corvette ZR1's these are no nonsense no questions asked fast american cars..

Hey jimscott not sure if this would help?

had to laugh at the KIA but apparantly KIA's are meant to be good cars these days.. same as the new Hyundai's... if i could run two cars i would get the LS400 but it has to be strictly the 1989 release model first ones to roll out of the production line but i dont think there are any left in UK maybe US or Japan. was thinking of it as more of an investment rather than an everyday driving car.

havent used them before but they might be able to help. http://www.cheaptoyotaparts.co.uk/

http://www.themotori...port_sedans.htm So the Journal above is about Sports Sedan/Saloons but which 5 cars would you love to own? I would love to own… 1989 Lexus LS400 Known by the motoring world as a car which redefined luxury cars and how luxury cars should be built. I recon these LS’s will be collector cars as they are known as the first ever Lexus. 1990 Mercedes-Benz E500 /CE300 I used to be a Mercedes lover .. mostly the older models…My dad owned the 1989 Mercedes-Benz 190(modern day C class) and this car went every where. I still recall us doing trips to different countries during holidays in this car and it covered the miles with ease. Never suffered any major break downs only needed oil and coolant changes..very strong cars and they built like war Tanks and I think the E classes have a timeless design to them. 1999 Nissan R34 Skyline GT-R (Nismo Z-tune) There is no other car on the road today which looks like this car. I love the design of this car, I love the speed of this car even though I have not driven one..Yet..its a sexy looking car. Not Italian sexy, not German sexy but Japanese sexy! And these cars are known to give a Bugatti Veyron a run for its money from its 2.8 litre 6 Cylinder engine…I want one now.. 1999 Honda S2000(JDM Spec) You gotta love a fast screaming Honda..I love these cars for the sheer fact they are about as close as one can get to a formula 1 engine with regards to revs.. This 2 litre 4 cylinder Honda engine without a turbo charger chucks out 250bhp and revs to 9000rpm not a lot of cars below £100,000 can do this…infact besides Mazda RX8, LFA’s Ferrari’s and Lambo’s no other car revs to 9000rpm in stock form. Sure most will say 250bhp is nothing special but that’s not the point.. These cars out of the box are 100% track cars and No I haven’t driven one on a track before but just watching countless videos of these cars on a race track tells the story of what they are capable of. Around a race track, these 2 litre sewing machines can embarrass more expensive high performance cars with bigger engines and more power. With an engine developing 125bhp per litre this is a master piece of an engine.. 2001 Lexus IS300 And I happen to own this one. Refer to the link above and see what the Author had to say and I agree 100%..No wonder i keep going on about it in threads :) What are the 5 cars you would love to own?? .Not necessarily a sports car.

not sure if fitting just the cone to the existing OE intake tube would work as you wont have anywhere to house your MAF sensor once the airbox comes of cus the MAF sensor hole is linked to the rear part of the airbox. as you know the air box has two parts. the front part and rear part so if you can find a way of housing the MAF sensor then you can use the OE intake tube but it might not work cus the intake tube is quiet short in length and what you want is to have the cone as far away from the engine as possible so as to not soak heat..but if you can get hold of a longer intake tube and drill a hole to accomodate the MAF sensor then you are a winner :) . regarding lsd's i think all IS300's sold here in UK have one.

5W-30 100% fully synthetic oils should last 12months or 10,000 miles...but if you drive hard every day or use your for track days then 5,000miles should be ideal. but for normall stop start driving or motorway driving every 12months or 10,000 miles is fine but best to keep an eye on the oil level occasionally and top up if necessary.

sorry mate! i meant the Apexi panel filter.. this is a dry cotton style filter which makes the engine sound a bit more throatier than the stock Toyota/Lexus filter.. the sound is note like a full blown cone induction sound, but its better than the stock filter.. induction kit will give a more sportier sound for sure tho... have you now decided which one to go for ?? Just incase you was wondering the one i have http://www.funkypower.co.uk/catalogue.php?make=TOYOTA%20-%20LEXUS&model=IS200-IS300-ALTEZZA&year=&level1=AIR+INDUCTION&level2=AIR+FILTERS&level3=&id_product=7089

my guess will be it was programmed that way to save the transmission. if 1st was made available it will max out so quick you would not have time to react in time to change to second gear so Lexus thought they will leave 1st to be handled by the computer as it will be 99.9 % accurate when it comes to when to shift than us humans. that only leave 2, 3 4 and 5 for us to play with.
