whats up guys i'm designing a crazy turbo kit customs fuel rail aluminum intake manifold exaust and 2nd fuel pump and emanage fuel computer and a gt28 turbo prob a turbonetics or a percision or unless i find a hks for cheap lol but i have a few questions for you motor head guys i'm redoing the whole exaust and wanted to know if anyone knew if taking the cat out will effect that secound 02 sensor sense these things have 2 but if anyone has input or wants to find out more just post in

 

of course taking out the cat will affect the o2 sensor. that's why it's there.

you can have a resistor installed in the wire tho, tricks the computer into reading correctly..

crazy azz turbo huh? i'm guessing you're paying someone else to do this for you haha.

 

actually not!!! ive never let anyone work on any of my car for the past 3 years i'm 18 and know alot the only thing i didnt know about is that i didnt know if i was jsut a emissions thing cuz if it is you can get rid easily do you know the correct resitor of hand or do i just need to do the math if anyones knows itll save me time thanks

 

i'm pretty sure the resistor value will vary between cars.. here's what i suggest...

test the voltage coming/going out of the o2 sensor at idle.. maybe revved up to 2K.. then test the voltage when the o2 sensor is unplugged..

compare the two voltages, and you can use your resistance formula to figure out what OHM resistor you'll need..

 

you could just get a high flow converter too. They shouldn't pull that much power away and will leave the air minty fresh.

 

what he said

 

yeah you really sounds like you know what you're doing :? why would you run a second fuel pump and an emanage? you run a seconf fuel pump if you are gonna run an EFMU

 

Taking out the catalytic converter will cause the motor to rich out and the check engine light will come on. The computer will try to compensate and the motor will just run rich like a mo fo.
I know because back in my beginings here in scionlife, I made one of the first straight pipes for Eric M. He told me everything that happened and I used the data he gave me to research what had happened, after the straight pipe was installed.
Installing a resinator in the place of the cat will not work either, nor will putting in resister to the 02 sensors. These DAM 02 sensors have gotton so sensivtive, you need the right amount of emmission going through it. If you want the high flow cat part number that will fit our vehicles PM me and we will talk somemore on the subject.

 

Just a thought....don't mind my blabbering..


aluminum intake manifold? Shouldn't you first figure out the fuel management? Putting parts together is the easy part. Trying to figure out the proper sizing of everything seems like a lot of work, especially if the fuel management is taken care of yet. Trust me.. I gave up.

 

I agree, was any measurements put into consideration?

 

yeah there is math and science behind building a manifold, you just don;t weld a tube on runners and truthfully you will blow the motor before a new intake manifold is needed

 

Well said.

I hate to say it, but i was one of those "I can make turbo kit" guys. And i did.. I had everything in place to get to get started... then i got stuck with fuel management...and i'd rather have someone else take the time to R&D everything, instead of me with a blown 5 month old motor...

Now someone bring on the turbo!

 

i'm working on it

 

Well, hurry up peppy, I miss the blow off valve whoosh!

 

ok if some of you dobt my knowledge well dont ive been reseaching and working on turbo apps for a while its just with the new computers or adjusts they did i and almost everyone else need to work on but what i was doing with the emanage is i dont think that allows you to adjust fuel press to much and sense i might get a custom crank from a local shop and rod and pistons i found a place online that does customs cylinder sleeves so with all that i dont know how i would blow a motor which hey if i do hey i dont care i go to school at a mech school work my ___ of and over the summer im hired at a local service department the same place i bout my xb and already talked to the service manager about the whole engine parts layout of it and everything and but back to the emanage thing i was thinking that would be easier than like 2 3 seperate computers to run the ail fuel ratios and vtec and ____ but im gonna see first if im gonna need the extra fuel pump once i start to turn the boost up and if i do im running it to the custom fuel rail and adding a secound inlet or even 2 little ones with a seprate uel presser reg so i would have to run it all the time. but hey i dont know how much fuel i can force through it till i try so hey we'll find out keep me posted and thanks for the cat info about the strait through tube cuz thats what i wanted but hey i guess i cant run cat less
peace
thanks

 

typicall that 02 sensor (the 2nd one) is used only to check for catalytic functionality. You get the check engine light coming on but nothing else. the resistor trick (easier on some cars than others) can keep the light from coming on.

 

this is a reply to STYLIS

yes i did take lots of considerationg of measurement one of the things im working on is finding other 1.5 through 1.8 camparing the inner deminsions of intake manifolds and then taking a look at the inner demminsions of vemon and aem and edlebrock manifolds to see how much air space was added and looking at the type of power those manifold can produce i think i want mine pretty close to those specs but still not sure

THE OTHER'S
lets just say the building of parts is a totally dif story i got a hydrolic pipe bender and a welder and for the aluminum my uncle can help me sense he has the tool not me and my dad was an engineer for 25 years and so the whole computer ____ takingcare of along with percision building so hey you never know but if there are any other brave Xb TURBO men out there that want more than a 20% INCREASE ON A GREDDY TRUBO PROPS TO YOU ____ THAT TURBO I COULD PROB USE THAT ON MY MINI BIKE IF I LOWERED THE BOOST A PSI OR SO LOL

PEACE

 

You may find that taking the time to punctate your text will make it easier for others to read and understand, and also that people will be more likely to take you seriously. This can be useful not just in social interactions like these, but absolutely crucial in business.

 

YOU KNOW you can buy a complete greddy turbokit for under 2000 dollars right? (minus the intercooler)

you WILL NOT be albe to custom ANYTHING for under 2grand.
