I know that the Lexus AFM along with the 550 injectors are a popular upgrade. I would like to know if the AFM off of any Lexus is the larger one or is it only off the V-8 engines. I have found several different types of Lexus AFM's starting from a 93 Lexus 300 with a 2jz engine and wondered if even that one was considered the larger upgrade and is the same as all the "larger" AFM's off the Lexus cars.
This is for my turbo by the way and I would like to make this upgrade. I can buy local or I can go ebay, but I was just curious about if there was any difference with any of the Lexus AFM's and which ones to look for and which ones not to use, if any. Thanks Russ 87 Turbo |

The LS400 V-8 seems to be the winner

i just got the ls400 afm and talk about a big difference. i am just running stock boost and stock injectors but it made a big difference on how smooth the car actually runs.
there is a part number for the afm that you need which is 22204-42011 the actual afm is bigger it seems to be about 3". i got mine from a scrap yard, i called lexus and they wanted over a $1000 for it. the only reason i didn't want to get it off e-bay was incase it didn't work or something then i could return it. i will be getting bigger injectors and an s-afc soon so i can up the boost. |

Will the ls 400 afm just plug into the stock wiring or will that need to be modified too?

you remove the wiring (black box)off the lexus afm and put the supra's afm block box onto it .
you'll need to get the 25% larger diameter afm inside the accordin hose that connects to the turbo. --sounds easy you really shouldn't add a lexus afm without knowing exactly what you are doing . you should have an air/fuel gauge installed you should have larger injectors installed

Wait a minute, I was always under the assumption that it is a plug and play item. I have never heard of anyone having to swap out the black box from one to the other. I am pretty sure they both have the same plugs and then yes the upgrade for the injectors.
Anyone outhere that has this mod? Besides shoving the larger afm into the smaller bellows, that should be if for that. Russ |
