Thumbs up Defiant Autospeed Does porting? You bet we do!

I have been doing turbo and exhaust manifold porting on the side since mid 2003, I have done over 100 turbos for people on NASIOC, and now, finally, I can advertise my services. I also do TGV deletes, in fact, below is a set I did recently.
Why pay someone to do it for you?
Because its something that while not brain surgery, its easy to mess up in such a way that you start to actually lose performance. Especially on the turbos. Want to do it yourself and dont know how? Ask me and Ill help you out. But I always recommend that if you arent 100% rock solid sure you can handle it, dont chance it. I have seen a lot of ruined turbos from people overporting or enlarging the wg passage, or gasket matching too far so that its larger than the gasket. Even a tiny spot can cause a leak. Not hard to avoid, but not hard to mess up either. Its also one of those things that is really tough to do right without the proper tools. A lot of people suggest using a dremel. That just isnt realistic if you want a good port. It would take you forever (seriously, 4-5 times longer) to get the same results as you get with a large air compressor and the proper gringer and bits.

What I offer
Turbo exh housing porting and polishing.
Wastegate porting (done RIGHT)
Turbo compressor porting/polishing
Exhaust manifold porting and polishing
Exhaust manifold porting (more like gasket matching/transition smoothing)
TGV deletes
Throttle body port/polish
Gasket matching/polishing the intake manifold where it meets the TGV housings.
Cast up pipe porting/polishing

Pretty much anything that can be ported/polished/improved on, I can do it.

I have done a couple cars where I ported/polished almost everything, and the changes are very apparent, and really put the car apart from others with the "same mods"
Here is the most recent I did.
Turbo hot side
smoothed inlet and outlet of compressor side of turbo
Smoothed/knife edged TMIC elbows
throttlebody
Exh manifold/crossover, wrapped the crossover as well
The owner said the gains were suprising, and the driveability of the car was transformed as boost response and even off boost throttle response were both improved.


Why port and polish?
Well lets start with the turbo. A picture is worth a thousand words.

This shows how poorly the exh side inlet matches the gasket. Gains are typically spoolup about 300-400RPM sooner, transitional boost response (on/off/on throttle) and boost holding to redline are all improved as well.
Here is one of my first from back in early 03. This is a shot of my VF22 that on a 2.0 spooled to 14PSI by just before 3000rpm, and was hitting over 21PSI by about 3300-3400rpm. Remember, this was on a 2.0!
Peak HP will also go up slightly, but this is a mod that the gains are a lot more than the sum of the peak increase. The gains in the area "under the curve" are where this shines.

The outlet of the hot side is also opened up to promote flow, and this helps the boost holding at high RPM.

What about TGV housings? Why port them?
SEE LOWER IN THE THREAD FOR UPDATED PICS OF TGV DELETES!


That is why.

Look better?


I dont think I even need to explain the benefits there.
You will get a CEL from this, however if you have a reflash, your tuner can simply "turn off" that code and you will never have a problem again, and have no issues passing emissions.
*PLEASE NOTE, YOUR TGV SENSORS,MOTORS, FLAPS AND RODS WILL NO LONGER BE ABLE TO BE USED, SO UNLESS YOU TELL ME AHEAD OF TIME, THEY WILL NOT BE RETURNED TO YOU (as they are effectively garbage at that point anyway)*


I dont have a picture of an untouched throttlebody, but here is the deal on those. The factory one has a roughly 1/8" "step" where the inner diameter shrinks down to the size of the throttle plate. This step causes turbulence, which slows airflow. This isnt a huge problem, but the faster you can get air in and out of your motor, the more power you can make.
The bolts that hold the throttle plate onto the pivot bar are also smoothed/shaved down to lessen their impact on smooth airflow.
This is also a great time to do the throttlebody coolant bypass mod. I will include the parts needed for that mod along with detailed instructions for an extra $10 if you want it.
Here is the throttle body off my miata after I smoothed it out


I dont port/polish heads though. Porting and polishing the things that I do does require a certain level of knowledge and experience to reliably get it right, but porting/polishing heads is an artform, and I am no artist

I will also wrap pipes for an extra fee. The cost will depend on the cost of the materials needed.



PM me for details and rates, I assure you that my rates will NOT be beat.


***I do not offer coating at this time***
But my porting/polishing services are cheap enough to send it to be coated and still come out ahead in almost every case
I can paint the parts with a high temp ceramic coating, however this is not the same as something like JETHOT or Swaintech coatings.


No website or phone number yet, PMs are the best way to contact me at the moment, or hit us up on AIM at defiantautospeed

added disclaimer on the TGV delete service

Never done heads> I would be able to gasket match and smooth about an inch down in, but I wouldnt want to touch beyond that. I dont know how well they are matched to begin with though. Could be not worth doing.
Head porting is a whole different ballgame. (ball game.)

Cool

What did you see?

FYI I learned a LOT checking out the Blouch's I had bought. Not so much HOW, but how nice to make the finish. I was always function over fashion before, concentrating 90% of my efforts on shape, making it relatively smooth. Then I got my blouch and it was SOOO buttery smooth on the inside. I actually am going to start using a 180 grit for the "finishing" work to get it shinnier, easier


Speaking of Grimmspeed, I need to get your addy and get my isht shipped to you for the coatings.

irony... since I am not a huge believer in coatings.. But I want the pipes pretty and I figure, if I do ALL of that stuff, its got to help at least a little right?

Do it! That was we all get the best of both worlds, port/polishing and coating.

No I mean my pipes for my personal car. I am doing it mostly for show reasons. This is after all, my rolling showroom

Once I start porting/polishing a LOT of turbos/manifolds I will talk to Grimm and see if they want to work out some sort of deal that would be beneficial to both of us. Being "competition" may hinder how much of a deal he wants to give me on that though
Like I said, I dont believe in coating turbos or cast iron manifolds, I just have never seen anything pointing towards measureable gains, however, I get a lot of requests for it, so I may look into offering it. I am not putting a lot of effort into that though, I just dont think its worth it. On a header, thats a bit different, stainless headers suck for heat retention, I personally think wrapping them is better at heat retention, but a ceramic coating cant get soaked with oil and catch on fire (which is why if I wrap a crossover pipe, I then wrap that in aluminum tape)
