i ran the wastegate source to a point after the intercooler to avoid boost sag...can see/hear the wastegate opening while driving so it seems to be working well. Of course this is only with a 5lb spring, but I'll keep the same spring when I start tuning boost control so i think it should be just fine

Unfortunately the EFR's wastegate discharge does not allow much more than a small nut and washer below it as it interferes with the stud.
I ended up using Stage 8 on three of the four studs and just used a OEM nut from Nissan on that one stud. Held up well.
Great build!

@Savington at TSE makes some.

See above. Still won't fit.
Nissan's studs are Inconel and are ~$4-5 vs a full TSE stud kit. It's worked just fine for me with standard hardware. I also ended up using Norlock washers and after 8-9 trackdays (one with 100+ degree outside temps for the entire day), no issues with backing out. I also made sure to hang the downpipe correctly and that alleviated a majority of my problems. I was also only 3-320 WHP on my 240, so also not full 400WHP heat issues.

aidandj, The issue is not with stud length, but with the locking hardware. The Stage 8 stuff is a fair bit taller (considering the locking shank or whatever it is called) is itself 1-2 mms thick. Anything apart from a standard nut, regardless of stud length, suffer from a severe lack of room. The wastegate discharge runs right over one of the studs in most cases.
Here is an example. A shorter stud does help, but not with Stage 8 or any other hardware that adds height. It seems the TSE kit uses the standard locking hardware as well. I am not seeing where they include a shorter stud?? According to their directions
But I could also be very wrong. I am sure Savington will tell me if I am incorrect. But from my experience, using the Stage 8 hardware was a no-go on the side with the wastegate discharge. I also had my housing ceramic coated, so I wasn;t doing myself any favors either.
The stretching is a precursor to them stretching and unwinding the nuts and then the studs themselves backing out entirely from the flange.
The SR20DET (what I used for track days and such) guys have suffered this just as long, if not longer, than Miata guys. I am on the throttle at Summit main a fair bit with just 200 TW tires for it to be problem for me initially.

3) Reinstall your turbocharger and install the four provided Stage 8 fasteners. On the lower, rear-most fastener, apply Resbond 907TS to the threads of the stud/nut. The Stage 8 retainer/clip interferes with the turbine housing. Tighten all nuts to approximately 10-15 ft.lbs.

Thanks savington. I had had several housings with the varying molds and I have had the pleasure (or displeasure.......) of experiencing all of them . That directly affected the effective volume one had available in that specific area.
The picture above is not mine directly, but was one of the newer housing molds for reference. The older molds made it impossible in that area.
