FIRST B-SERIES MANI USED, FIRST TO USE Options

hey your problem  might not be broken rings, but when i blew no. 2 piston on my car i got alot of blow by and oil would come out of the bov.

dude you can't shoot oil out the BOV from the combustion chamber it defies PHYSICS.....
think if your forcing air INTO the engine....wat makes you think that oil can come out through the intake valve, upstream through the intake runners, and upstream through the intake manifold, out the TB, and down the pipe and out the BOV its physically impossible.....

that just what i was thinking Lagos.......

not many of the turbo guys are using a catch can for the blow by

yea that and is everyones drain lines at the right angles and
lines correct sizes?.......

thats a lot of blowby tho, if your car is smoking. a stock 3s motor dosnt use a catch can and donst have these types of issues. there must be something else at the heart of the problem

[playr158]

lagos its cause the n/a motor design swapped into a turbo isn't designed for the extra pressure and pushes it out more so then say a stock 3s which is designed for such

ok ok back to the point now are we just talking 7afte or 5sfte also

i guess i can walk back through my install step by step i dont think i forgot anything but you never know and i started with a used turbo from Zipstrips

[lagos]

nik, i saw zipstrips car in action and got a ride in it ...way back in the day. he was blowing lots of blue smoke at the time and had a coke bottle catch can setup....if that helps you any. i think he also said he was on his 2nd or 3rd turbo at the time

[playr158]

ouch that means there is a design flaw in the way we're setting them up

[dustin15brown]

So have you figured it out what was wrong yet?

that sucks we gots to find out whats goin on....

[lagos]

Clement ..

im no 7a guy....but it looks like you have the valve cover pcv line hooked up directly to your throttle body. that is not correct and would make your car smoke. you need to hook up an intake with 2 niples on it, then hook up the valve cover line and the other line to the intake. then connect the intake to the turbo inlet.

[lagos]

looking at your pic again..... looks like you used part of your injen intake, and have a vac hose (where is that going to?) and temp sensor running to it... if i were you, i would extend the wiring for the temp sensor and route it to measure air between the air filter and the turbo inlet, because the way u have it now could create a big boost leak

[presure2]

if i were you, i would extend the wiring for the temp sensor and route it to measure air between the air filter and the turbo inlet, because the way u have it now could create a big boost leak

actually, art, thats the wrong spot for it.
i havent even looked at his pic, but i can tell you that the right spot for the IAS will be in the intercooler piping, between the intercooler and the T/B.
in the 5s/7a the ecu selects the fuel map by looking at the map sensor and ias, and putting it in the intake pre turbo is gonna give you a false reading.
you want the ECU to see the temp right before it hits the T/B, just like stock.
::edit::
i just looked at the pic, and as long as youve got a solid seal there, (cause art is right, it WILL create a boost leak if you dont seal it well) thats where you want it.

[lagos]

yeah i guess so, but i can see that hole being hard to plug air tight ...and arent the fuel maps under boost controled by the piggy backs people use anyway ?

[presure2]

art, "controled" and piggybacks are 2 words that do not go together.

the piggybacks dont control jack, they just manipulate.
they do nothing to the "fuel maps"
they just modify the signal to the ecu, "tricking" it so to speak.
as for guessing its the right spot, it actually makes sense when you think about it,
if you put the AIS preturbo, your not seeing actual intake temps. the air still has to go thru the turbo, get heated, thru the piping, the intercooler to get cooled, then to the T/B..
you want the ECU to see the temp as close to what it actually is going into the TB, so that it selects the proper fuel map for the temp of the air going in. thats what the IAS job is, to tell the ECU what the intake air temp is.
now, on the 3s, its a whole diffrent story cause of the way the ECU uses the AFM to read airflow..ect

[Clement]

yea i have it sealed really good.... and i was told to leave the pcv where it is and yea in that pic the release valve is just hangin out LOL; but now i have a catch can and i'm waitin for a new turbo to see whats goin on

[lagos]

yeah i know how it all works...lol

what i was trying to say is....
on the 3s, the afm measures intake temp and the amount of air, through the afm, before the turbo. the odd thing is, you would think toyota would want to measure the air after the turbo heats it, but they dont. that leads me to think that the those sensors arent as critical as we think they are. it probably has the range of a narrow band o2 sensor, reading hot or cold... and nothing in between. so, really you should be able to put them just about anywhere and it wouldnt matter much.

i remember the gromet that i had to use for my sensor when i had my injen in there... that thing definetly didnt look like it was air tight..lol

[playr158]

yea art you have to remember 7a is not AFM

so lol its different for us....and trust me it can mess up a decent amount with out that in there post intercooler

[nik]

this is where i put mine right before the throttle after the turbo


and it worked fine

[playr158]

i'd think a rubber grommet and a lil high temp silicone should do you fine
