Hey,

On the weekend, i took of my turbo (a try to fit i new one but the new one didnt fit due to having the incorrect lines) so i put the old turbo back on.

Now i am having boost problems; When setting my boost to 0.8bar on my Profec A EBC,

The car accerlarted then i get boost cut, power kick back in, boost cut power kick back in, also i get alot of missing firing, random backfire (alot of black smoke out of the exhuast)

On top of that my airfilter doesnt sound the same under accerlation, same goes for my BOV;

My idle is also having problems, it wont hold at 900rpm it drops to about 500rpm and almost stalls then kicks back up again

I have check the following things

EBC< -All lines are connect right

-No air Leaks

FMIC<-All Pipes are connect right

-No air leaks

BOV<-Connect Correct

-No stalling related problems (i didnt have a problem with it before i change the turbo)

I have a feeling it might be AFM related on something to do with the pipe which connects the AFM to the turbo.

Does anyone have any idea?

The problems doesnt happen when i run stock boost or 0.5/0.6bar

      Factory LSD is supposedly a 2 way with a very conservative cam. If you've already tried adding friction modifier to the diff oil and it still locks up too much for your liking you might want to adjust the ramp rate on the cam to be more like OEM instead of reducing initial torque even further. People claim the 8 kgf-m disc kit for the OEM LSD is still very streetable but I've never been able to compare everything side by side on my own.

      Oh man, at least it sounds they've accepted they stuffed up and not put it back on you...could see some confusion if they asked if it had a hardtop or not, and you've answered truthfully but maybe not answering their real question which is what roof did it have from the factory! Glad your keeping it N/A 2.5

      Nah, I much prefer colour matched Talking about colour matching stuff, the new/used boot lid turned up, all painted up perfectly......aaaannnndddd, it's for a power retractable hard top, not a soft top.....LOL They are now sending a boot to fit a soft top.....,  whilst frustrating, life is like that sometimes, sometimes you just need to dodge, duck, dip, dive and, ummm, dodge.

      You would need to paint your hardtop again though

      I have an old R32 in the shed that hasnt moved much in the last few years and probably should see the light of day. At one point I had a Nismo 1.5 centre put in the rear diff. It is a clunky nightmare POS of a thing on a good day. To make it less painful the initial torque setting has been put on the minimum (7.0kgf-m, mid is 9.5, high is 14) and the oil changed out to something more slippery. But it is still awful and ruins the vibe of the thing. So my questions are: Given I have the original parts sitting in a box somewhere would it be better to rebuild the thing again, reverting to more purity? Is there a standard kit or do you just go and replace the friction plates etc and shim it the way you like it. How much initial torque does the standard R32 rear diff have? Or does the Nismo disc kit offer a better solution - the caveat being the initial torque for both options appears to be higher than the clunky 1.5 way. There appear to be two Nismo disc kits: 3843S-RS520 for 8kgf-m. 3843S-RS521 for 12kgf-m. Or is the easiest solution to reshim the Nismo diff to make it looser?
