I need some clearing up on the downpipe installation, I still don't get if I'm supposed to weld a flange on the cat or the downpipe? And if I need to cut off a piece from the downpipe or cat. So lets say I need to modify my cat by cutting and welding the flange on it, does that mean the stock lancer downpipe wont be able stay on anymore and the evo downpipe will need to go on right away?

old exhaust
test pipe installed and flange welded
what I did was cut off the old flange from the exuast that connects before the cat and welded an evo 8 downpipe flange on it so I can bolt up either my downpipe or test pipe, now if I want to pass emissions I can put an evo 8 cat in place of the test pipe before I take it in

nice pictures! So if I wanted an exhaust shop to do this I have to give them the evo 8 flange to weld on, does that mean my exhaust will still fit even if I'm not ready to install the evo 8 downpipe yet? What I'm trying to say is that how will I drive the car if I have to weld the flange at one place and install downpipe along with rest of the turbo at another place?

I have an evo 8 midpipe, I skimmed through the posts, it has the flanges on it, I'm not sure if you would need it or not. If you payed shipping I could send it down for free, it's just been taking space up in my garage.

Ok I have all the parts I need that I listed so I took them to my mechanic for him to take a look at and I found out several new information.
First off about the manifold he told me it was badly cracked and of cheap quality like the ones from ebay and that it will keep cracking even if I had it re-welded so I was advised on getting a new one that is made of cast iron. Next I have to get a map sensor that will go more than one bar (whatever that means). Lastly relating to the installation is that I need an adapter or something like that to fit downpipe to the 02 housing because the mouth of the downpipe is larger than that of the housing (see turbokitpictures010 in the attachments below).
The next problem is even more complicated than that and is somewhat unrelated to the installation but to the running of the whole car itself. So I have my check engine light on and it's running in open loop and on safe mode according to my mechanic which means its not running properly/normally but I don't see any difference. Almost two years ago I had the auto tranny swapped with a manual of the same car. It was done successfully but incomplete because the ecu and wiring were still that of the automatic. After the diagnosis all it showed was bunch of codes relating to the auto tranny not being there such as torque converter, shift solenoid and what not so I continued to drive it like that without running into any major problems. One minor problem that occurred from time to time is that when the car first started for the day it revved all the way up to 2k or even 3k sometimes then came back down to steady 800.
The reason for posting all this is because I want to know how big of a problem will this pose if I decide to install the turbo without completing my transmission conversion first by getting the whole engine wiring harness and ecu swapped or can I do it after I put the turbo in. And what does it mean to be running in open loop and safe mode. This decision to go through with one or the other will postpone the latter.

make sure you get a donut gasket for that turbo O2 housing to the downpipe

thanks Steven, so any OEM evo8 downpipe doughnut gasket will work right.
I ordered the speedcorps manifold instead and its also coming with a mounting bracket. everything should be good to go after that arrives. also which map sensor will fit my car that's needed after boosting?

i never changed my map sensor when turboed

Alright I'll look into the evo map sensors, thanks. Did you bypass your map sensor or how did it work with running a turbo? I hear that the lancer stock map sensors aren't able to read so much air going into the engine which is why an upgrade or bypass is necessary. And if I were to tune the ecu then a real map sensor needs to be present so bypassing it wont work.
On a side note here is a pic of my intercooler (thanks braydon for finally shipping it =)

You're welcome.
Sorry for the long wait... completely my B. Good luck with the rest of the install. Oh, you found the bolts for mounting the intercooler taped to it right?

Yeah I got the bolts, do I only need two? because that's how many it came with. I just need to find someone to install it. Majority of the shops do not want to take on something like this because of something put together like this not working right.
Is a larger MAF required swap for turbo or is it recommended?

Evos 8/9 map sensor are the same as lancer to the best of my knowledge. Unless your running SD you do not need to worry about your stock map sensor. Maf swap is only recommended not required but I would still upgrade to at least a 501 or better the 399 evo maf like me . Two bolt are all that hold the IC on to our cars the top one is not needed.
