Porting a turbo

[Justinawd]

Ok I picked a 14b turbo really cheap and its in awesome shape since its going to be about a week before I get the install kit and gaskets I figured for something to do I could port it out. What kinda porting tips can you guys give me and what would be a good bit to use on my 18v cordless drill, I know it will be a slow process with that drill...

Unless you're porting and enlarging the wastegate, don't port the volute. You will get creep.

when I did my DIY porting on my 30r I used a carbide porting bit from lowes. Ibelieve it was around 20 bucks. and I used a wire wheel to smooth it out after. just make sure you dont over do it. port a little. smooth a little.

Yea I was going to port the wastegate and the knock the ring off maybe go a little bigger. I was also going to open up the flapper so it could open all the way because right now it doesn't...

Do you have an aftermarket or ported O2 housing?

EVO III o2

Right now I just want a little more than the T25 and my brother 1g AWD makes plenty power on his 14b but I hate the boost creep so I figured I would port it to make thinks run cooler and spool faster while trying to get rid of the creep. He ended up finding out the hard way showing off to a buddy and made a highway pull running 18 psi and it crept up to 22 and he didn't notice it until he blew his head gasket.

There's more information as you go through the posts. And you will find what tools I used.
Let me know if you have any questions.

You won't get anywhere fast with a cordless drill.

Yea I know I just conned my buddy into doing it for $40 bucks he has a big compressor die grinder and the carbide bits for grinder and he is off of school right now and does nothing but sit at home so he was more than happy to do it for me...

Good decision. Even with carbide, using a cordless drill would be a month-long process. Using a 5 gallon compressor was a long process itself...

Well I talked my buddy into removing a broken stud and porting it for me and he ported it first then found out he couldn't get the stud out and we took it to a shop and they wanted 75 to 125 to remove it so I ended up buyin a used housing for $30 so he gets to port another one

Just remember not to port the flapper to much or it will not seal right and it will leak.

Don't touch the volute.
