Ok so I went ahead and bought the megan, only $100 shipped brand new so cant b**** too much. I will weld some supports on to help against any cracking.

 

Just another note. Most (not all), of the people with tubular manifolds that cracked also had tubular O2 housings. Most of which are unsupported. This puts lots of stress on the runners on the tubular mani's. I think that a tubular unit along with a supported O2 would fair much better.

 

forget the o2 housing, buy an o2 dump.

 

The dump always sounds cool (I meant of having O2 dump over O2 housing) but it actually sounds pretty loud though....won't be good for a DD though, right?

Plus, what's the gain of it over a ported O2 housing?

 

You won't hear the dump in normal driving. It's only loud when your flooring it causing the wastegate to open.

 

That's what I've read too...and it'd fit my DD perfectly since I rarely WOT at all during the DD Then, what's the gain over a ported O2 housing then?

 

Ya I have been looking at the 02 dumps thinking about getting one of those, I bought a stock 02 housing for like $18 shipped off a member here so wouldn't be a big loss if I didnt use it

 

You will get faster spool up and gain more hp. Not sure of the exact numbers. I just purchased a shearer o2 dump, and I'll be getting a retune shortly. I'm curious myself to see what kind of gains that I'll get.

 

Then why are you posting this in the Evo forums? You're planning to hack the flange off and simply attach a 4G94 flange? That makes my head want to explode.

Forgive me, I'm not familiar with Lancers, is this a commonly accepted practice or something? How do you know that it will even fit? How do you know that it will fit with any kind of Evo 02 housing/dp? Is the deck height even the same? Is there room to stuff all that in there? Things to take into account from a fabrication standpoint. You can't just start welding stuff together and hope that everything will fit.

 

Yes this the common low budget best way to go and no all I do is weld the flange directly to the 4G63 flange many turbo base lancers have this, the runners from the 4G63 and 4G94 are ALMOST identical just off by maybe 1/4" this way this will allow me to use a evo DP with a 12" extension or like me I am going to just get 3" straight pipe all the way back to a magnaflow muffler. There is only one 4G94 to 16g manifold available right now and you need an external WG which I will not be using. Trust me I have been researching this non stop for about 3 months (and I mean like 4 hours a day) I posted this in Evo forum because my original question had nothing to do with my build just wanted to know which of the 2 EVO manifolds would be better and since this is the EVO forum..., BTW thank you for some heads up on different issues that may have arised but I have taken into account everything thus far

 

Okay, I understand now. Looks like you're off to a good start, best of luck.

 

ive had my megan for more than a year now and i have a solid front motor mount. No cracks at all. I also have the megan o2 housing.

 

Thanks alot aschold much appreiciated I know alot of evo owners will come on the base lancer FI section and comment "why didnt you just buy an evo?" My response is including the price of my car, new paint job wheels, transmission (my car I bought at a bank repo) misc dress up parts and my custom turbo build I will have $6000 total into my car with 220hp at the wheels, I wanna see someone post who has bought a running driving NOTHING wrong with it evo for 6k. Anyways as I said thanks for the support man and to everyone who contributed to this thread.

 

Hey, you are right on doing whatever you are doing Please post some pics of your car, and good luck with your projects. I think most of us on here really enjoy working on our cars no matter what kind of cars they are

I'm anixous to see the turbo setup in yours

 

Here are some pics of my car, once I get all my parts together I am going to get pics of everything and make some video as I put it together
