Porting an EVO3 gt. different material?

[Necromancer69]

Ok, I bought an evo3 gt from extreme motorsports and i am creeping bad. however i've heard that the exhaust housings on the gt's are different then that of the MHI evo 3. does anyone have any background on whether or not it is ok to port the exhaust housing of an evo3 gt. or does anyone have an MHI 16g exhaust housing they can sell me. any help would be appreciated.

the "GT" is already supposed to be ported. its a "updated" version of the MHI EVOIII

have you ported your o2 housing yet?

my o2 housing for lack of a better term is gutted. the exhaust housing is supposed to be cast with a port. they are not actually ported though. any other thoughts? i know how to port and everything i just heard things about the material they used to make it.

is your exhaust mani. ported? that might help a little bit

and if all else fails, you can always run an external tial

dont really wanna go that route i'm just trying to find out whetherw or not the material on the evo 3 gt can be ported. i'm kinding trying to stay away from the external as i dont have the money to go that route right now. i'm thinking maybe in a year or so when i go with a bigger turbo i might go there but for right now... but can the material of the evo3gt be ported and still hold up to temperatures it will see.

Lets restate. Has anyone succussfully ported the evo3 gt with no negative effects?
