VF26 (VF27 CHRA) Turbo smoking


Recommended Posts

Hi all, looking to get to the bottom of this...

 

Have a BH5 legacy, had some major play in the vf26 that was in it so got a cheap vf27 and swapped the CHRA from it over (http://www.subyclub.com/topic/5276-diy-convert-your-tt-primary-turbo-to-ball-bearing/), however every time i've test driven it, there seems to be smoke coming from the turbo.

 

I've done some reading and founds that the BB cores require much less oil/pressure than the journal bearing, which is what the original turbo was so could possibly be too much pressure? I've checked the oil feed banjo bolt size and the hole is about 1.5mm but cant remember if this was from the original VF26 or the vf27.

 

And now I'm wondering whether I put sealant on the back of the compressor plate when I put it back together >.> would that cause this issue?

 

Other thought is that the cheapy turbo was already busted...

 

Any thoughts?

 

Thanks

Smoke coming from the turbo itself, wut?

 

Sealant on the compressor plate isn't going to make it smoke.

 

1.5mm is on the larger side for a ball bearing turbo, I believe the standard ones are 1mm? But also unlikely to actually be an issue.

 

Did you re-use the copper washers on the oil and coolant feed banjos, and if so, did you re-anneal them?

so you've gone from a 26/27 pair to a 27/27 pair?

 

other than that sorry no useful imput from me

 

oil pressure could / should be the same yeah?

      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
