Evo III manifold on 2g

[calico]

Is the evo iii manifold and o2 housing a direct bolt on for a 2g turbo? If so, will it give me a few more horsepower than stock. Found a great deal on one and am curious. Did a search and no info. Thanks.

Search a little harder its their,, the evo manifold is a direct bolt on. the 02 housing isnt, i think certain dp work, not 100 sure on the 02 houseing, search evo 02 hosueing.

When searching, make sure you are limiting the scope to thread titles only-- you will end up with fewer threads to sift through, which can make finding your answer a whole lot easier.

In my opinion, the amount of work to pull off the turbo doesn't justify the gain in power you'll see for this mod. I would wait until you're ready to upgrade the T25 before investing that much time. I had my stock manifold ported when I upgraded my turbo, which has worked just fine for me. The O2 sensor housing discharges at a slightly different angle than the stock unit, which makes downpipe fitment a little tricky. You will also either need to modify your existing downpipe flange or get an EvoIII flange welded on to replace it, as the holes are spaced a little differently.

The evo III 02 Housing will bolt up with some work. It's flange to the downpipe is at a slight angle.
You can either get a downpipe to match it,
or you can get a flange and an exhaust shop to weld you on the flange at the right angle..
The EVO III 02 housing is a lot bigger then stock, i have the pictures of the difference around here somewhere.

EDIT: Blast, I was beat to it.

blackbyrd-- I guess we're even now.

 

[blackbyrd]

For now..

do you still need a o2 housing when you go with a aftermarket downpipe? or is that part of it?

 

[blackbyrd]

Some aftermarket downpipes eliminate the 02 housing.
Thus you'll see them listed as 02 Eliminator Downpipe.
Most downpipes however still retain the use of the 02 housing.

 

[formulav893]

so if i get a tsudo or megan downpipe i would still use my o2 housing, i have a evo3 as well and i havent installed it yet.

 

[blackbyrd]

Your going to have to get a downpipe thats matched to the EVO III 02 angle.
Or you'll have to take it to an exhaust shop and have them weld a new flange on your downpipe (shouldnt cost more then 10-20bucks)

 

[formulav893]

that sucks, the guy who sold it to me told me it was just a simple swap, although a simple flange swap isnt bad its just the idea of cutting and welding on a brand new downpipe..

 

[blackbyrd]

You might be able to get away with bending the top of the pipe to make it fit. Some have had luck.
Someone around here sells the flanges, i forget who.

dejontool sells downpipes that fit the evo III 02

I thought they sold the flanges too

 

[formulav893]

says their DPs only fit awd cars not fwd's. i guess ill have to modify a tsudo or something

 

[blackbyrd]

Heres dp's for FWD 2g's

enjoy!

 

[formulav893]

thanks, 230 is pricey but i guess its bolt in and no messing around.

 

[blackbyrd]

No problem! You might be able to shop around the vendors here, and find some cheaper, but that's the only other ones I knew about offhand.
Good luck!

Oh, and if you haven't, check out EBAY. I got a downpipe that was flanged for the evo III and the evo III 02 housing for I think 100, or 120.

I realize that you have a 2G, but this is the best I can do for now.
