Primary wastegate porting


B4 I was 250T

I'm sure this has crossed your mind, but just in case all you need is a little encouragement....... DIY

 

If its just the wastegate that needs porting and you're not trying to port and polish the scroll of the turbo then absolutely DIY

Oh it crossed my mind but I also don't trust myself and can't afford to screw it up! But thanks for the vote of confidence ;)

I believe someone here (and I don't remember who but I think it may have been Rosssub or Lachlan) did it. Apparently the flapper is bigger and a little bit of material can be removed. Wish I could remember who did it?? :|

Look out for a spare from pick a part, doesn't matter if it has a stuffed bearing, just crack into the exhaust housing! 

Don't remember when I last went to pick a part but overtime I've been they've never once had a tt BE/BH :(

 Hornby has at least one TT currently, intake and exhaust headers have been removed so the turbos are just sitting there

imo removing the V-Band holding the housing to the CHRA would make the job alot easier and eliminate the risk of metal filings getting places they shouldn't be. 

 

The most difficult part of this entire processes is actually removing the turbo from the car :rolleyes:

Is it worth it? Is it really going to make much of a difference?

I don't know if it is but at the same time why not? I have a spare primary that's off the car at the mo and because I refuse to ever go S/T I might as well do everything else I can. If it makes a difference, great, if not then I haven't really lost anything :)

From memory when my primary was off the car, which may be the spare you have anyway (?? my memory is shite tho!!) or was that the secondary? anyway I think the wastegate flapper opens past 90 deg when its disconnected, so it may be able to be bored in a mill, which any engineering shop with a mill ought to be able to do.

 

The one on the Track Hacks TD-05 does anyway.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
