Hello guys, I have a question for you...

I have in my Evo 4 a FP Black turbo, but I run that turbo with the stock 02 housing.. I think is very restrictive.

I`m looking a good 02 housing aftermarket, what do you recommend???

I don`t know if my 02 housing is equals in diameters to evo 8 02 housing.

thanx!!!

 

Bump!!!!

 

I think MAP performance has some of the nicest option available- Check out their true 3" O2 Eliminator Downpipe.

 

DO you mean this one???

I mean for the price hehehhe!

 

You might want to look into the Invidia O2 housing.

 

+1 on the invidia.

 

I`m looking an Invidia right now!!! thanx guys!!

 

I have an Invidia and it seems to work great. Only problem is location of o2 sensor. I had to make the wires about 2-3" longer.

 

this is what i have on my car and i love it!

 

You may need to inquire about whether the fit for an Evo VIII or IX will be the same as for your Evo IV before you get too far down the road in buying an O2 housing.

 

Agree with above. Contact MAP fir an application for your car

 

Yeah I found out and is the same!!

 

how does the Tomei Expreme rank compared to the invidia 02 housing?

 

would o2 dump create more power than internal housing? i always get different opinions...

 

With bigger turbos yes. With a stock turbo probably not so much
