Porting E316G

[TSITurbo95]

I saw the vfaq about porting. But I just want to clarify some things up and want some other peoples opinions. I have an Evo3 Big16g, and want to port it. How far do I go in, and how big to make the hot side. Also about the flapper, ive heard it does nothing, but I also heard it helps. Does anyone have any pictures of their ported 16g? Also any more info that I should know about while trying to port it. Thanks.

Well I have no pics,but on my evo3 16g I ported for creep.I ported the lip completely off the manifold flange.then I proceeded to the wastegate hole.if you look the hole is so hidden it seems very hard for air to make it through the wg hole.you want to turn it into a nice smooth path for the air to go out.think if you where the airflow where would you rather go?port until its a nice smooth air friendly entrence,not a sharp 90 degree transition.make sure you keep the conical shape as you port also.now the actual wg hole,port that too.port until its close to the size of the flapper,but don't over do it where the flapper won't seal anymore.now the last step I did.the wastegate flapper arm.open it as far as you can,it will most likely not open a full 90 degree.port behind the arm so that you get a full 90 degree opening swing.take your time and make sure not to remove too much material.you can always take away but not add.last but not least make sure you still get a full 90 degree wastegate arm swing inside the 02 housing.if not port the 02 until it does.this method solved my creep and held rock solid at any psi with only 2psi max of creep on any gear.hope this cleared up a little guys.

That helps. Thanks, anyone have pictures of a before and after?

what tools did u use just a dremel. Anyothers that could help?

You don't use a dremal to port, it will take weeks!!! A die grinder.

 

[2gGSXEclipse]

Did know if you could use it to try and get farther into the o2 hhousing.

 

[TSITurbo95]

No, just use a longer bit/extension on the die grinder.

I did.the wastegate flapper arm.open it as far as you can,it will most likely not open a full 90 degree.port behind the arm so that you get a full 90 degree opening swing.take your time and make sure not to remove too much material.you can always take away but not add.last but not least make sure you still get a full 90 degree wastegate arm swing inside the 02 housing.

A complete waste of time considering the actuator only allows the flapper to open 3/8".

The porting you did to the turbine housing inlet to help direct airflow toward the wastegate hole is what helped your boost creep.

Does anyone have any pictures of their ported 16g?

Free up about 3 hours, get all of your bits lined up, and be ready with tweezers to pull shards of metal out of your hands (and feet if they work into your shoes).
