Default need lexus AFM & 550cc Injec

Im sorry about making a new thread for this but i cant find anything on here about it. I am confused as to which Lexus AFM i should get. No one specifies a model and year i should get it off of. And also when i get 550cc injectors that only ones i can find for the 7MGTE motor are around 550 bucks!

im sorry but that still doesnt tell me where to get the injectors or the AFM. I already know that i need the injectors to compensate for the air. Or was there one specific thing i was suppose to read in there that would actually help me?

He did say read the whole thing...

You need to understand what you are doing...

Its not as simple as lexus maf + 550cc = OMG WTF POWER

driftmotion.com for the injectors... They are not cheap... Dont skimp here it will mean an early end to your engine.

suprasport.com makes a lexus style MAF for this purpose but its not cheap and they have lots of complaints on customer service side... They are a machine shop and honestly should let someone else run the parts side of things but if your patient you will get a high quality adjustable MAF

. Look in the for sale section on supra forums for ppl selling a lexus maf, plenty out there.

That article was written buy the man who invented this mod. He spent his own money and time to explain in detail why he did this and what happened when he did. It is more involved than just "a lex and 550's" you are tricking your ecm and messing with the fuel cut in an attempt to run more boost. Read it all and understand what you are doing so you dont end up with a permanently garaged supra.
The sensors were rare and extremely expensive at the time the article was written. You can find them everywhere for pretty cheap nowadays.
The AFM comes off pretty much any lexus with a 1uz-fe v8 4.0L.
They are for sale all over ebay.
You only need the housing, the sensor is the same as your supras.
DO NOT skimp on the injectors, yes, they are expensive. Actually R/C's are pretty cheap compared to many others.
You can have your original injectors cleaned and resized if you cant afford new ones.
