Lexus AFM?

[ThirstyMKthrice]

i keep reading about the lexus amf and all that. honestly i have no clue on it. lots of people keep telling me to get one too. all i know is that i need bigger injectors. i searched the site and after going through about 11 pages and not seeing anything at all i thought id leave a post.

I think it's best if you have your engine rebuilt and turbo with a higher than stock PSI before you look at fuel upgrade.

But if you do have it built. The lexus afm is just a bigger air flow meter. Since you have more airflow you will need a bigger injectors and since you would need bigger injectors you would need a better fuel pump etc etc. Search a lil harder, you'll find tons of info on it.

That is backwards. Support upgrades are done before power addition. Well, not to those of you with an em kay 3.

you can put a lex afm o& 550's and not raise the boost, it raises fuel cut because you get more air too.

i know all this but does it matter what lexus i take it from?

If you knew all this, how can you ask such a question? You need the same kind of airflow meter that comes on the Supra.

i mean i knew about needing bigger injectors and what it does, i was out of it last night and worded that pretty bad. i really meant to ask does it matter what lexus it comes off of?

Yes. It must come from one of the 400s. SC400, LS400, GS400, that part doesn't matter, but it must be from one of them.

thats what i was lookin for, thanks. now what are my chances of finding one of these in a junkyard? and also do those cars already have the bigger injectors and would they work on my car?

 

[Dan_Gyoba]

IIRC they don't have larger injectors... They just have 8 of 'em instead of 6. You'll need to get your larger injectors elsewhere.

Decent chances of a junkyard find (AFM). You can use injectors out of a USDM 2JZGTE, RX7 Turbo (IIRC) or you can just buy new ones

Nope, not usdm 2jz...

If you dont know what size injectors or even what type of AFM you should put in your car, you 100% should not be thinking about upping the boost.

You guys all have it wrong.

FIRST comes knowledge, then fuel upgrades, then supporting mods, then turbo.

 

[ThirstyMKthrice]

man ive got knowledge. im not a moron. im just new to supras. you never have this kind of stuff on a honda lol. and dont flame on me for having a honda. i traded it for this car. i also just dont know what half of these abbreviations mean. iirc? i have no idea.

Read this:

Then, if all of your questions aren't answered, by all means, ask.

 

[ThirstyMKthrice]

damn, that about covered everything i could ever ask lol. thanks a million for that read.

edit: will doing the lex afm really let me run 1bar on the ct-26? my mods are in my profile

 

[Quin]

I didn't say they were drop in, I just meant they'd work
