I'll go through all the hoses tonight and make sure. Forced Perfomance sells both the single and double flapper. The single is the newest design they are using on the MR. Thanks for the pointers.

Used fighter garage's leak tester and found that my lower IC hose was leaking. Running great now. Glad it was something so simple. Thanks for the helpful tips.

 

i ordered my 10.5 hotside from bushcur racing, hopefully gets here this week, then install next weekend....

 

No, it probably wasn't. You're not going to make 3 tenths in a 0-60 with a 10.5 hotside. That was probably a tiny bit because of the hotside, and a lot because of the driver/conditions/air temp etc etc.

Cars and mostly drivers are not consistant.

 

Its actually used on all the 2005 turbos, not just the MR!

 

I am in the middle of this, the ***** is the v-band clamp....what is the bolt size for the clamp? Of course, mine is facing down...any tips for takin off the clamp?

 

8mm IIRC, and a long extension, maybe a flex head. The thing isn't torqued that tight....

 

Sorry, what is an 8mm IIRC?

 

8mm
IIRC= "if I recall correctly"

 

I figured it out....kick *** write up Superhatch...would have went without a snag...if I would not have broke a downppipe bolt..I am dumb.

 

You're welcome... sorry you had troubles.

 

good writeup, just trying to decide if i want to spend the $100 for the o2 housing or just go for it. not sure if it's worth the extra cash...

 

In the vendor section Speed Element has them on special for $249, check them out.

 

great write up, this thread really give me the confidence to tackle this install....and in addition, my brother who has worked on repairing tanks and Hummers will be supervision as well.

 

You have an 05 evo....you already have the 10.5 hotside brotha.

 

Thanks a lot SuperHatch for this write-up! I did this install yesterday and your guide was right on.

I do have a note for anyone like me who kept the stock O2 housing...actually, this could work for either:

You can leave the 02 sensor in the 02 housing and still remove the lower heat shield. Just cut a small slit in the head shield while you are under the car and that will allow you to remove the shield through the top of the car and not have to mess with the sensor in a crappy location.
