Hi guys i came here for help finding a o2 housing upgrade for my turbo, it is a big 16 g and it has a very small , 2.25 outlet i think? o2 housing, my o2 sensor is mounted else where so i dont even need it to be bunged, however i would like a 2.5 inch version that flows better, cast or tubular it dont matter as long as i dont have to change my downpipes flange or angle. sorry if this is a newbie question but i didnt know who else to ask, incase you didnt catch my name i dont have a dsm i run a honda, but i used a big 16 g in my set up. i dont want to port my current one i would rather buy a proven design.
 
thanks guys , i will check them all out, my main concern was getting the wrong one, since i dont know what the difference is between all the evo turbos out there.

i found this one on ebay, my next questions for you dsm experts are, are these shaped teh same as teh stock so i dont have to change my down pipe length or angle? and also how much do these tubular ones improve the big 16 g? right now it seems that the stock 2.25 inch outlet is making alot of back pressure, what can i expect to gain from a tubular o2 housing such as this?
i really like this one that the guy above posted as well Modern Automotive Performance  :: DSM  :: LIPP Cast Stainless Steel O2 Housing (DSM) is boost creep the only thing these help with? i am looking to gain a little more whp and also have less back pressure on the motor.

These are shaped the same as the stock one, so you will not have to modify your downpipe.
 
I have an ebay o2 housing with a dumptube on my car and I like it.. haven't had any problems as of it and I've had it on for about a month now. Makes the car sound amazing under boost.
 
i would want to recirculate it , but i was also wondering about power increase? does this mode really make this turbo allot better? because my tuner says he has teh turbo about maxed out righ tnow and he is blaming the stock o2 housing , so i want to be sure if i upgrade it it will mean a pretty good improvement.
 
When I upgraded to a 2.5 inch o2 housing I could tell a noticeable difference. Im not sure of the size of a stock dsm o2 housing or if that is the housing your running, but the stocker is very restrictive. Its definitely worth the money for one of the ebay ones, or any for that matter. And as said above it'll bolt right up

You probably won't notice much of a difference at low power levels. With no porting I think it would become a major restriction somewhere around 350hp, depending on the rest of your setup. It also depends on if the turbo is an Evo 3 16g or just a Big 16g.

How much power is your tuner making?
 
right now i am at 300 whp, he said i could probably gain 30 more if my o2 housing wasnt creating so much back pressure, i have the normal big 16 g, so that creates my next question is there a turbo that is better then my big 16 g that would bolt on right in its place with out me having to change my manifold and hot and cold pipes? the big 16 g seems to be about at its limit right now, which is why i was hoping a better o2 housing would help some.

EVO III 16G or a 20G.

20Gs are nice. ;) Almost bought one but couldn't justify spending my whole paycheck on one.
 
so both these turbos would bolt on with no changes? that is cool to know, can i bother some one to tell me how these compare to each other ?
 
Well how much power would you like to obtain? What are your supporting mods? How much boost are you running/want to run?
 
i would like to reach 350 to 370 whp with out the turbo huffing and puffing to get me there, my big 16 G is pretty much maxed out right now at 20 psi and 350 whp on my set up.
 
Personally I'd go with a 20g or Hybrid 60-trim. I've heard the 18G (Greddy I think) is a very nice turbo as well.
 
being still a noob in the world of turbos, can you tell me in layman's terms how these 3 turbos compare? right now the big 16 g i have is very street friendly it spools pretty fast and all that, i dont want to loose my low end torque curve yet i want it to breath easier up high.

this is what I have as well as a lot of other people. Its a bullsye T04b vtrim bolt on turbo, internally gated. I think its rated up to 400whp or 450. I have heard nothing but good things about it I cant wait to put mine on, cant really beat the price either!!
