I want to perform a so-called "Big 3" on my Lexus for my custom car hifi installation (and 3 Kinetik Audio batteries). Will it work on my Lexus IS 220d car? Any advice, recommendations? I don't know if this will hurt my car or not, but people recommend on car hifi forums in the USA recommend to upgrade this. What's the "Big 3" you might ask, well here is an explanation: More information on "The Big 3" can be found at the websites mentioned below: - The Big 3 - link 1 - The Big 3 - link 2 - The Big 3 - link 3 Will my Lexus IS 220d benefit as well? Or is it dangerous for the ECU or something?

As i said there would be Denso numbers on it But remember who owns Denso yepp TOYOTA hence the reason why they pushed you back to the dealer and all the dealer will know is a part number from the EPC also the Alternator might be a new type for the IS220 as you will find the one fitted in a D4D on a Avensis TOYOTA does not have the same output (not as many electrics to cater for on the charging side What is it you are looking to run from the car that needs a higher output Alternator? Well 3 amplifiers in total; 2x monoblocks strapped and 1 4-channel bridged. Would be around 2800W RMS. With my older setup (less power) I already had the problem that batteries didn't get charged fully with music playing. I am now in contact with one custom high output alternator builder in the States and he is trying to contact Denso in order getting more information about the alternator specifications (dimensions, bolt type, etc.). However, after contacting more than 20 companies, I seriously doubt it will be useful. Anyways if this seems to be fruitless, I will stay with my stock-alternator. This "search" is costing me to much time and frustration. :(

Okay, I removed some of the plastic covers on top of my motor, therefor I have "more" (= a little bit) access to the alternator. I took a picture of the information on the alternator: As you can see, it not only shows the part number from Toyota, but as well for Denso, along with another code (in the yellow part) which I don't know what it means. I still find it weird, that even when you have the product codes, you cannot cross-reference (or let alone look it up) on the internet. Even Lexus and Toyota dealers I emailed cannot supply me with the necessary information (bolt type, dimensions and specifications). Sigh... I also contacted Denso about their alternator, but they refer me back to my dealer, who doesn't know anything about the stock alternator. Very un-useful! :(

Thanks for the answer... Seems I am really screwed though, cause over here in the Netherlands or close by I have absolutely no option for rewinding my current alternator (or buy an high output alternator) and in the USA they have problems cross-reference my alternator with one of theirs. So they know how to build my custom high output alternator. I should never have bought a Diesel car; not enough options compared to their gasoline partners (IS 250 & IS 350). I contacted several companies who build and / or sell high output alternators in the USA and I supplied every one of them with all the information I have available, but all resulted in the same kind of answer: "Sorry but we cannot cross-reference your Lexus IS 220d alternator with one over here in the States". Really sucks... And I really need more amperage for my car hifi installation. I can try one "final" thing; getting some decent pictures from my current alternator in the hope that will give them enough information to build me an high output alternator which does at least 250A. Sigh....

Is this what you want this is the one for My IS220d 27060-26030 12V 130amp not sure on make but they are usually Denso units As TOYOTA Own Nippon Denso Regards Matt Hi Matt, First thanks for taking the time to answer me! Highly appreciated. I tried searching on Google, but I couldn't find more information on 27060-26030? You didn't make a typo right (no offence meant here)? Do you have any pics as well? Sorry if I sound demanding, but I am hardly an expert and I don't dare to take out the alternator myself... Regards Hello no offence taken yes that is the number from EPC but sorry i dont have a photo as i dont want to remove anything from the engine area Question why do you need one as i guess this would be covered under the 3 Year warranty and as the IS250/220d is not 3 years old till November take it back to a dealer Regards Matt Thanks man... Well I really need an high output alternator, but therefor I need some information on the stock alternator.

Okay it seems to be a 130A at 12v alternator... ...but I need to know the brand, type, etc. Anyone who can help me out there? I already tried Lexus techdocs, but no succes in finding information

Hi guys, Anyone here who knows the type of (stock) alternator a Lexus IS 220d (2007) has? And what amperage it runs? Also some numbers / brand / etc. would be nice. I am currently not near my car (and I won't be the next few days), but I need to get a new alternator as soon as possible. Your help is highly appreciated! Thank you. Regards, HHawk

Forget it, this is a waste of time.

I already sent them an email, but they say there aren't any HO alternators for a Lexus. :S

Yeah... That kinda sucks. I know (I looked up a long time ago) that Lexus IS 220D stock alternator does about 130A (my previous car, an Audi A3 Sportback 1.9 TDI had 140A; 10A more then my Lexus!). I don't know what your alternator does. Anyways it's hard to get this kind information. I will make an enquiry at the garage next month, cause I need to bring it in anyways. Would be nice to have a more powerful alternator for my (power)needs. I already contacted a few companies, but none have answered me so far. :( Regards, HHawk

* BuMP! * It seems everyone is happy with their standard alternator here? No one has a high quality sound installation in his car?

Does anyone know if there is a company here or in the United States who are selling High Output alternators for a Lexus IS 220D (or similar)? Let me know, thanks.
