Hey everyone I'm installing a megan o2 housing on my evo 9 this weekend and was wondering what kind of issues would I be running into cuz I heard on the 8-9 its very common for the bolts to snap wile taking the oem off. So any heads up advise will be great thanks

 

PB blaster the night before on everything. re-apply more then once.

 

never changed mine but if bolts are breaking then heat will be your best friend

 

I'm pulling my manifold off this weekend and I've started my PB regimen early

 

Heat the housing around the bolts trying not to heat the bolts and pb the **** out of them.

 

be sure to pb the o2 sensor and don't strip the bolt on it like i did.

 

You are going to have lot of fun doing it. I sure did

PB and lot of patience.

 

I just finished my o2 dump last night. Broke one bolt. I would advise a lot of pb ad a decent breaker bar and some prayers for no broken bolts but they are .50 cents at hardware store so no biggie if so lol. I went the radiator route gave me a lot of room and I didn't worry about torquing the exhaust manifold back. Set back 3-4 hours or more of first time. Good luck bro.

 

Did you get stainless steel bolts at that price? Anything less than that won't do a very good job of holding up to the heat of the turbo

 

Two two bolts I got were for the downpipe. I've taken it out so many times one finally gave so I changed them both. Grade 8 bolts stainless. My buddy helped me out so he may have marked them down lol idk he didn't say. Either way it isn't gonna break the bank

 

I was going to torch the bolts but didn't think of pb so ill do that for sure, and should I use stock bolts if they don't snap or buy some stainless. Thanks everyone so far for the advise lol

 

Well I had some trouble with the o2 sensor I ended up have to remove the old o2 housing and torch it to get the sensor out lol pita

 

Also are all the gaskets and doughnut gonna work fine when I put this in or should I get all new ones

 

I spent 40 dollars on a good map torch. Found out a new sensor was 57 dollars. New sensor here I come.

 

The new oem front o2 isn't $57? A universal may be I think the Bosch is in that range
