how much tuning is involved with Lexus AFM and do I have to have the 550 injectors first so as not to melt pistons.I am doing this on a very strict budget.(disability check)and attemting to be able to survive aswell.Cant take a chance melting pistons cant afford to fix the eng.Need a solution this is my only car.It is needed daily for therapy exc.

Save for the injectors before installing. You can run the stockers (it's been done), but untuned I wouldn't risk it. BTW, without fuel upgrades, you won't get the benefits safely from crossing fuel cut anyhow.

Thanks Bob I am tring to fix this car up on a shoe string budget any help is greatly appreciated.I have to do all work that has to be done (if possible)cant afford a mechanic .Im disabled and that barely pays the bills.So this project may take a while. Bryan So far I have a T04eGarrett turbo,manual boost control,3"ss downpipe nocats,3"n1 turbo muffler,BOV need to get the thing to turn up more than 2100rpms.With the MAF unplugged it turns up to 2800rpms.That is why I think I need a MAF It ran well until I turned up boost to around 13-14 then started not turning up rpms.and acting like a blown intercooler hose but they are all good.

busybeezturbo,
I think you're going to have problems. That 3" SS downpipe was ment to match up to a CT26 (most likely). Have you test fitted it on your T04E?

What about going to a VPC Setup? This removes the MAF and turns it into a speed density setup. Most of the high HP mk3's are using HKS VPC/ApexI S-AFC combo setups.

[busybeezturbo]

How much does the VPC cost? the T04e came off a MA70 engine and allready had the turbo elbow on it .It fit fairly well

[Jeeves]

You'd have to piece together a VPC. It's a discontinued item. Though they still cary the wiring harnesses and the injector ROMs.

If you're looking to drop some decent cash, here's the perfect package for you: here.

I would like to be able to buy that however I jumped into modifying my supra without inquireing about the consequenses of what it would cause.I thought just add a big turbo and life is good. Now I see it is not that simple when one thing is modifyed it sacrafices another.Now I have a monster on my hands that wants to eat money.While it was running it ran like a striped ass ape.(0-100 about 7 sec.14lbs boost) Now I have to feed it more money to get it back running.

Yup, that's mk3's in a nutshell.

feel like I have a monkey on my back!!

Do you know if the Lex housing # is 22250-50060 LS400. On line some one said there are diffrent ones and some dont improve performance?

[americanjebus]

if you go for lex afm , ur gonna want the 550's, new walbro fuel pump, and a new fuel rail. and if you realy want to take good care of your 7m a fuel pressure regulator. you cant do this cheaply and expect golden results. thats the downside to our cars, they are very expensive to maintain especialy now that our parts arent manufactured anymore.

[Jeeves]

You don't need a fuel rail, have you ever looked at the factory Mk3 Fuel Rail? If you need more than that you better be pushing 800rwhp.

You do NOT need a walbro or an aeromotive adjustable fuel pressure regulator (AFPR for short), if you want MORE boost then you'll need these things, but you don't need them if you just are doing the Lex/550 upgrade.
