I need a Garrett 4-bolt O2 housing, I've heard Victory makes them, in the midst of e-mail's with them. I'm just wondering who else is out there? I heard AGP's name get tossed out once, but of course, nothing is listed on thier site. I see 5-bolts all over the damn place, but no bites on a 4 yet...

I guess I should throw in that I'm also looking to purchase a MAFT setup and 680/720s, and I'd like to order them all from the same vendor...

You could try AMS, they've fabricated stuff for me before. www.automotosports.com

show me the back side of that turbo. i might have the 4 bolt flange for it.... so you could build the o2 housing.. as i have many 5 bolt and 4 bolt flanges to make 02 housings..

If I had everthing needed to build it here, I'd go for that... I ordered a flange with the turbo just incase it came to that, but thatnks...

Very very old thread, but incase anyone is looking for this information, www.punishment-racing.com makes Garrett o2 housings.

How does this work with all the differant T3 manifolds out there? How do they know where the turbo will be placed?

That appears to be a top mount T4 manifold. I would assume that the turbo outlet pipe/downpipe is designed with that manifold in mind.

I'd like to know that too, but I'm guessing that they probably designed it with one manifold in mind, this one - http://www.punishment-racing.com/budgetmanifolds.html

This is probably a question for Tim at Punishment racing.

We designed it to work with either our budget or premium t3 manifolds, but it fits some other tubular manifolds as well. We can also do custom pieces as well.

So what other manifolds do they work well with?

With respect to custom pieces should my manifold not be supported, is this only applicable to local customers?

Also, as it appears from your photos on the website, why did you choose to place the O2 sensor bung at the very front of the O2 housing? Personally I'm planning to run a WB O2 and eliminate the stock O2 with a narrowband signal from it, but it appears this might be too close of a placement for a WB O2 setup.

So far we've fitted them with the dnp's and the various ebay special manifolds and the fitment was good. If your using it with any of the cast manifolds out there you would either need to tweak your stock downpipe or have a custom piece built.

We can build you a custom housing without the car here, but would need the manifold you are using to fit it properly. The o2 sensor bung we can place anywhere on the housing you prefer, and add another if the customer requests it.

A wideband sensor needs to be about 18" after the turbo flange and yes, the stock o2 sensor location is too close to the turbo flange for a wideband.

Tim and DGajre777, thanks for the additional information.

For those of you that may be considering to build yourself an 02 housing for a 4 bolt outlet setup, take a look at this piece I picked up from ATP Turbo. Its a 2.5" flange that converts into a 3" V-band. I now have about 1.5" of 2.5" exhaust on my car, the rest is 3".
