Your vacuum should be sitting at 20 (or very close).
If you've got smoke on Decel, very likely turbo seals.
If you've got oil inside of your intercooler, you've most likely got a bad turbo.
When a turbos fins are chewed up or really anything that causes it to knock off balance, it starts flinging oil everywhere....Everywhere of which goes to your intercooler. There's been cases of people dumping out literally QUARTS of oil.......and they wonder why they were having to put oil in their car every day! :icon_evil
Anywho, sounds like you've got a turbo issue. :icon_wink

NVM that car should have a LEX AFM not a FCD with 550cc injectors I miss that car it looks like it was kept in good shape.
Either way you got a good deal on that car.
But get a Wideband ASAP.

That could also be caused by excessive blowby, the PCV system is just pluming tons of oil vapors in to the turbo system. I think most of us with the stock pipes and 150,000 miles or more have a decent amount of oil in the IC and associated pipes, unless we have cleaned them.
I just pulled off the compressor outlet pipe stuck my hand in there... its not oily but there's oil in there and shaft play is little.
The smoke I'm describing is just like this guys Supra.

How could that be sarcasm? You suggested tech advice of some sort, I wanted to know why he needs it.s383mmber1 said:

that could be going rich,
i thought i lost my turbo seals, but it ended up being i was getting so rich i would decel and ignit the fuel in my exhaust, it looked and smelt almost like diesle.
If you want you can stop by my house with your car and I can take a look at it or you could go to one of the meets like the UCF meet on wensdays.

I just looked at the injectors they're RC engineering injectors! I dont know the size couldnt see them on there.
How can you tell if its a lexus AFM ?
You'll notice the obvious size difference in the AFM housing itself.
The area around the Electronics on the Lex AFM is much wider.
Also, Lex AFM's usually have a black sealed ring around the Electronics.
(Yes, I just took the picture), Notice PC Screen., and Yes, that is now a penholder.

Stock block (pistons) are good for 600 easy. Just don't run lean or let it knock.
15 psi on 440's is fine IMO. You are already too rich at 12 psi. I was good with stock injectors and an fcd till 17-18 psi before dipping into the low 12's (AFR). My fuel pump (stock MKIII pump) couldn't keep up past 14 psi though. I would get a wideband if you plan to mess with your safc or crank the boost up.

I have the one on the right, but I wasn't getting limited whats allowing me to do so I wonder.
OUCH.
Stock Supra AFM with potentially larger (assuming 550cc's) or larger injectors is a NO-NO. That is BEYOND an accident waiting to happen...:cry:
With an AFPR, SAFC & A FCD...your chances would be better, but that is still a terrible thing to do.
