Backpressure is not where it's at dude.....especially on turbocharged cars. So, get rid of the stock O2 hsg., and do an EPM dump instead. If the Tomei ARMS turbo comes with the stock, unported 10.5 housing, then port the turbine discharge area of the exhaust housing. Reduce backpressure, improve the pressure differential..... then report back.
I have driven 45,000 miles with an "El Cheapo" SSAC O2 Hsg. and can report zero cracked welds and zero warped flanges. Cast housings are not always better than welded tubular housings as far as integrity and longevity. I have seen factory cast iron housings develop leaks due to voids in the casting. Nothing manmade is perfect.

Sounds like the build is already planned, but the Works 02 housing would have been a perfect solution. Better flow, more HP, cast, and it retains the mount to the block to help support the weight of the turbo system . . .
Good luck with the tune. I am very interested in this turbo. . .

How much of a before and after test would we have if we replaced so many other parts to increase HP? Anyway if anyone followed your advice this guy will have an illegal exhaust on his car and lose his trucking license when he gets tickets. Additionally, An external dump on a street car is just a bad idea. It's loud and unnecessary unless you are intending to show off to friends. If one needs to run an external dump on a factory internal WG to just eek out that last amount of creep you have a badly designed turbo. Factory parts are always more durable than SSAC and almost always more durable than aftermarket parts that's why this one lasted 120k.
I agree with you about the external dump, i have never found a reason for it on a stock appearing turbo unless you are trying to scrape the last bit of HP out of a setup. But i completely disagree that factory parts are always more durable than aftermarket parts.

Mike this is a digression to say the least. Read the law again. It says no such thing. (anyway he is not a MA resident insofar as car registration.

huh? I thought this means it has to be an OEM or OEM equivalent. Anything different makes it illegal. All i am saying is that the O2 housing wont make it any more illegal than it already is.
No person shall operate a motor vehicle on any way which motor vehicle is equipped (1) with a muffler from which the baffle plates, screens or other original internal parts have been removed and not replaced; or (2) with an exhaust system which has been modified in a manner which will amplify or increase the noise emitted by the exhaust.

1) That's an incorrect interpretation you have.
2) Is this your car? No. So don't worry about why he is doing things the way he is.
3) PM me if you want to talk about law. I can do it all day we can also argue to make you feel cool. There is a huge distinction between an external dump and a notoriously quiet aftermarket muffler with a resonator inline (and a cat!) The inspection sticker on most cars with aftermarket mufflers will tell you that.

I could give a sh*t about that car, i was just saying that any SS recirculated O2 housing will not make the exhaust anymore illegal than it is.

Buschur offers(at least he used to?) a ported stock O2 housing that shouldnīt conflict with state law.
I also agree with you up to a point that dumps are usually overkill on a stock-based turbo. Itīs just that the stock unported O2 housing is undeniably a restriction even on a perfectly stock VIII 16G.
It wasnīt my intention to take the thread off on a tangent. So, sorry for the OT. Good luck with the Tomei ARMS! Iīll stay tuned to see how you like it.
