    Custom Turbo 2002 corolla CE

    Hi,
    I just put a custom turbo setup into my 2002 Corolla CE, but I was wondering if I have to do something to the VVTi. The car seems to stall when I hit the gas pedal, is this normal? I am currently running 5psi of boost.

    uhmm need more info what kind of turbo kit... does it stall at any other times?

    what fuel mods have you done if any...

    what engine management are you using if any..

    did you change the injectors or fuel pump?

    It could be a lot of different things,,, describe your setup better and maybe I can answer it.... It sounds like you may be flooding the engine out though.. or your maf isnt working well because of where it may have been placed... or the maf was placed backwards which would prob cause your car to be really crappy....

    is your Check engine light on (CEL)? and check and clean your MAF and also check if there is any cylinder misfire from a faulty sparkplug. hope some of these tips help

    I can almost guarantee you are not running any type of fuel management if it is falling on its ass under acceleration. Even at 5psi you need to increase the amount of fuel going into the motor or it is going to not run well and will eventually destroy the motor.

    Please let us know what you are using for fuel management and what type of setup you have. LoSx and I can answer a lot of your questions but we must have more information.

    Where is the MAF located? What size turbo? Manifold and wastegate type? Fuel Management?

    When the FMU on my car stopped working the car would stall out when I gunned it or when the boost kicked in.

    BTW!!! Welcome to the boosted life

    lol if hes not running fuel magaement then my answer would be get fuel management.... LoL

    split second or emanage for piggy backs or

    FPR which isnt as great but hey it helps....

    but yeah if you have NO fuel management then thats easily the reason its crapping out on you....

    Ok, here is my setup, I just put the turbo in last Saturday :
    I have a TD04 turbo from a 2002 Subaru WRX, custom header, turbonetics wastegate external, custom intercooler piping (2.25in), front mount intercooler, custom exhaust piping 2.5in, highflow cat and muffler, for fuel I am using a 5th injector 550cc and I am controlling the injector with a split second AIC1. Also I replaced the stock fuel pump for a walbro 255L.
    I have problems when going from vacum to 3psi if I hit the gas hard, if I am like 35mph or higher and I hit the gas, the car runs fine, a little flooded but I can feel the boost.

    how is a direct sending unit or a stand alone fuel system that is not even connected to the ECM/ECU and larger injectors and i don't even have a turbo! just a direct intake and the Ram-Air i have lying somewhere around my house.

    Did you get the AIC1 tuned? After installing the AIC1 you should have taken it to a shop with a dyno to have it tuned immediately. The AIC1 does not come tuned and needs to be tuned to your car for it to run properly. Believe me I know!!!

    remove the spring from the wastegate so it won't boost up till you get to the Dyno Tuner, get that thing dyno tuned then tell us how it runs. I guarantee you'll be ear to ear grin once it's tuned properly...

    hehe 5th injector... *sigh* that's almost as useful as the rising rate fuel management that SF tried to use on their kit.

    Actually a fifth injector setup is ten times better than what SF used. I had the SF setup and it was a joke and ended up destroying my motor. The AIC1 with a decent 550cc injector and proper tuning will yeild excellent a/f through 14psi. Anything higher than that and all new injectors and possibly a sixth injector would be required. Rick aka Raamaudio on MatrixOwners was running a fifth injector setup on his Matrix and that thing made some mad power and had plenty more room for higher boost pressure.

    yeah it seems like you need to tune the split second unit its prbably m,aking your car run too rich at lower boost so it dies..... sounds like a nice setup though...

    although i dont liek extra injectors cuz you dont always know if its being distributed equally... but its ok for lower boost applications.

    Ok, I found my problem!
    There is a leak on the turbine and oil is getting to the intake manifold. The leak is coming from the turbine itself not from the oil inlet and outlet. It seems my turbine needs to be rebuilt.
    I took the flowmeter out and it was very dirty, and yes I have the AIC1 programmed.
    Looks like I am going to need another turbnine, this sucks!

    if this is a new turbo then it may not be a blown gasket or whatever.... either your oil pressure may be too high or your downline may not be large enough.... i had to adjust the pressure on my system or id get blowby of oil as well

    ditto. too much oil pressure/flow is nasty. had a smoker for a little bit due to my oil pressure, lol.

    with or without the turbo? with out such as mine it is 3 psi at idle and at 1200 rpm it jumps to 43 psi and goes as high as 80 psi at WOT.

    on 98+ at idle its 4.3 psi which isnt bad....

    at 3000 rpms its 43-78 psi which will cause blow by... I dont remember how much is needed but 20 psi is more then enough for your turbo and 70 psi will blwo the seals and just squirt into the intake piping.. i cauhgt my bloby quick so my gaskets didnt get screwed but ive heard of peopel having such bad blow by they ruined there gaskets and had there turbos rebuilt after 2000 miles...

    a small regulator inline to keep pressure down is good enouugh.... remember its suppose to use gravity to flow out... if gravity isnt enough it can cause blow by cuz its not draining as fast as oil is going in.

    now his turbo m,ight have died from only blow by but it waas a factor im sure....

    also if your downline is routed really well you may have no problem but its a bitch to route it well and have a perfect drop into the pan.... a needle valve solves it quick

    Yeah, the MRS that got turboed at the shop near me had blowby issues with oil in the turbo because of the high pressure level. Guess I'll add an inline regulator to my list of stuff.

    As of now I am rebuilding my turbo, boosted life was too short, my return line is -10AN and is about 10in long, I do not thing the return line is the problem, but the presure... So, what type of regulator should I use to regulate the oil going to the turbine?

    a needle valve works.... hell even a home depot fitting (lol its was i am still temporarily using cuz it works) in there gas section works... or was it water section....

    or they have some things actually make to screw into the turbo opening that has a tiny hole in the bolt to let only a small amount of oil enter..... ill post up if I find where I found it!

    wow custom turbo set ups are a pain as I can see..... wow I really need to learn up on this crap when I get mine.

    They are a pain but you learn a lot too. Also a custom setup is cheaper compared to what they are selling out there. I spend about $2000 in mine and that is including the piping of the exaust which is not included on the kits that are outthere.

    Regarding the oil line, my turbine came with a screw that has a tiny hole but I could not find a hose to atach it too, so instead I made a custom fetting for it.

    indeed it sounds like a pain. but i will only need a low pressure turbo with a 50 shot of dry nos. since my car has its parameters re-programed it picks up very quickly after the 4K rpm mark. from idle to 3900 is the problem for me.with a high pressure it will probably mess it up, but i am not sure i could be wrong.
