If you're talking about the polished Y pipes from turbo to intercooler, i've been told by a few that the nismo pipes increase responsive and gives slightly higher boost and reduces turbo shuffle. Theres a article in speedhunters that covers the part, haven't installed on my car so can't speak from first hand experience.

Stock GTR airbox is good for 500kw, as is the stock paper element filter.

Sucking hot engine bay heat is counter productive.

Sounds like you're talking about pods?

OP is talking about the Nismo hard pipe kit, which helps reduce shuffle and the r tune intake which is just a larger version of the stock over the radiator intake, again just a potential small gain and no negatives.

Can't see how either would suck in hot engine bay air if the stock setup doesn't do that already.

Hard pipes usually do the exact opposite - in that - they make shuffle far more pronounced/problematic. Particularly when running larger twins, stock turbos not a problem but upgrade to -5s or 2530s and you're in for a tuning headache.

So no, they are certainly not a good upgrade IMO. Plenty on this forum have even REMOVED the hard piped and gone back to stock ones for that very reason, plenty of posts about it. So definitely something that article fails to touch upon but then he's still running stock turbos... They should be the first thing you change, not everything else first.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
