Q, I don't remember, but if I get a 14mm stubby open end 14mm wrench will I be able to get to that bolt without taking the DP out? I don't feel comfortable with how much I tightened that one bold.

From what a remember, there wasn't enough clearance between the o2 housing and the bolt to get any type of socket on.

Thanks

 

There are 3 bolts on the top side and 2 nuts on the bottom of the O2 Housing. I can get a short reach socket on all of the bolts nuts except the 1 nut furtherest to the rear of the housing. Use the stubby open ended wrench on that nut. I usually hand tighten that 1 nut before all others, that way you only have to load/torque it down just a little bit.

Hope this helps if any more info needed just let me know...

 

The one furthest to the rear of the housing is what I'm refering too. My car is put together already but I would like to tighten down that bold furthest to the rear a bit more with a stubby. Will I be able to get to it without pulling the dp off?

Thanks for the help. Can't wait, getting couple more stuff put on and have an appointment with AMS on April 9th Will definetly post the results.

 

You might be able to get to it without removing the DP, but at the most just unbolt it(DP) from the O2 Housing, let it sag outta the way. Thnxx for the posting the results, Im looking forward to it.

 

Does take time but it's not that hard at all with the radiator removed

 

In my experiences I couldn't get at that bolt from the bottom of the car no matter how I contorted my hands/tools

 

Best way to do an o2 install is to take off the (for the main part)

1. Unbolt downpipe from o2 housing
2. Unbolt Exhaust manifold (first the 4 bolts to hotside then off the head)
3. Wiggle out the exhaust manfold
4. Remove the V band clamp from the turbo/hotside and remove the o2 housing with the hotside.

PB blaster is your FRIEND!!! Especially when its time to unbolt the exhaust manifold from the hotiside.

Dumps make power but damn the noise!

 

Yep, 25whp and 42wtq gained here -- must not be worth it

 

I def. noticed a gain from just putting the EPM 02 housing on without tuning...i did make the mistake and put the stock gasket back in...so i had to take everything off again...i've done the 02 housing only 3 times now...first i put a megan 02 housing on then the EPM with stock gasket then EPM with the gold spray gasket...instead of taking the whole turbo out i just took the hotside off...since its been off already when i installed the PPI ported hotside...definitely took the radiator out too...PB blaster everything then antiseeze everything when it goes back together and you are good to go...oh yeah and the after tune power gains were pretty nice too...

 

Good advice on the install...thanks everyone!

 

I had mine on my car and it hurt the car performance wise. Not trying to be a heartbreaker but I had some major boost creep issues with it. Think about it. Look at the hotside of your turbo where the wastegate flapper is and look how big that port is then look where the EPM dump matches with it and its only a small hole that all that air coming out of the flapper has to try and fit through and it gets backed up in the turbo causing boost creep. When we took mine back off there was a solid inch of black making a ring around the epm dump tube hole where exhaust air was trying to get out but couldn't. Also the gasket that came with the car was obliverated where all that pressure built up trying to get out of the dump tube. If your exhaust is restrictive then yes this part will make you power but if you have a non restrictive exhaust this piece can cause some problems. Also my downpipe flange holes didn't line up with the holes on the o2 dump which made us have to put everything in a bind and pin my downpipe against my transfer case to get it to go together. Not trying to slam anybody but just sharing my experiece with this piece.

 

I'm sorry but the vast experience with 100's of customers does not back up your claims of lost power. The stock turbo and or FP Red can Not outflow the EPM O2 Dump. This has been proven over and over through dyno charts, unbiased customer testimonials and dozens of independent shops across the USA and the world. Our wastegate tube is a huge 2.5 inch which is bigger than even dedicated external dump ultra high horse power cars run. Our Exhaust chamber is 40% larger in volume than anything on the market. Our gasket is meant for a 1 time use only, it is not meant to be reused time and time again. If the unit is removed a new gasket is in order. As for the bolt holes, this goes back to our biggest challenge in trying to make our part work with so many different various combinations of aftermarket parts. Some manufacturers make awesome parts but others sell parts that are faulty from the get-go. Your Downpipe is one if not the best on the market, however you also have other parts that complicate any additional modification part added into your setup. It is not just an issue with one part but every part that is in your setup, if one part fails then it affects all the others that adjoin it. Again as always I will guarantee our part for any reason. If you are having a legitimate issue with our part I will make it right, whether it be to address and solve the problem or warranty it for a new one.

 

interesting. Thanks for posting! I was really interested in the EPM O2 dump so this thread definitely cleared a lot of questions I had.

Good thing is I will be installing the dump with everything out so it should be fairly easy

 

hmm.. I want to know more about this issue...

 

Ok now here was my problem and it looks like where I got this pic from they were having the same issue also. In the first pic you notice the right side where the flapper is and look at the shape of the port hole. In the 2nd pic the hole closest to the floor is the one that matches with that hole but you can see on the o2 dump the the hole is no where near the same size and look at this used o2 dump and you can see where the exhaust gas was hitting all around the dump tube hole trying to get out but couldn't which causes boost creep like I was having. I put my ported o2 housing back on and no more boost creep.
