I'm sure you could swap with a place like niswreck or just buy one then sell yours, and o2 sensors arn't the end of the world.... I got my nistune suplied and re-mapped for $750.. and i actually took out my power fc to do so...

Power fc's are great but you must remember they are not calibrated for a forged motor... each forged motor that is hand built/ not as tight tollerences/ run in differently are essentially different motors have more or less piston rattle and can produce a different harmonic frequency.

nistune have far better knock protection over powe fc, keep all factory settings, cops cant see it, amd a hell of a lot cheaper.... im a really big fan

WTF are you on about?

You can tune a Power FC much the same as a stock ECU with Nistune. Your motor internals have no effect. Knock detection uses the same knock sensor regardless of PFC or Nistune.

But I too am a fan of Nistune :P

yes they are the same in the sence its a editable ecu... but as far as i am aware power fc does not have a knock map, where once knock has been detect above limits it hits knock map and retards 4degrees of timing???

also yes power fc uses knock sensors, yes nistune uses knock sensors but what good is both protection if you have piston rattle that may / or may not have same frequency as what nissan engineers spent many many hours putting a "STOCK" motor into severve detonation to record the frequency???

it was just a point i mentioned, as many people buy power fc because it has a live "knock count" and spend 5X as nistune but as many tuners have said to me as soon as you change the slightest thing eg, exhaust your changing the motor and possibly the harmonics.

another example people might have devoleped a knock count to find something loose in the engine bay to be the fault not detonation.

      Returning after a long time!

      I havent bought a manual cover for the dash yet and no cluster change, won't bother me too much, I just need to get that auto box gone, manual in! I miss my manual. 🤪. We started last weekend and managed to get the box out. Planning to start putting it in this weekend and then order a single piece tail. We were super careful to take time and not damage anything. It's my first time working under the car.  With my S15 mainly worked in the bay. This time, it was a headache because of three or four bolts only. They simply didnt want to leave thei homr and the one securing the tailshaft, another above the GB, and the one securing the lipstick was a shit. Mates mate, Davo caught fire 🤣, nearly opened his chest up with a grinder 🤦🏽‍♂️ and both mates nearly had a plate from the box land and slit their head open. Fun times. We all survived. Not the easiest working with limited access on jackstands. As I'm sure we can agree these are the memories which make us love our car. For all three of us, was an awesome weekend and Sunday 3.30am before tools down was a fantastic effort. I need to upload pics, but looks like it needs to be via Url now. We used to be able to just upload pics back in the day. It's been that long! 🤪 Im currently spraying rustoleum under body, not because it's rusted. It's super clean, but just so it's protected for the next 10 years. There was a few surface rust spots. Which pretty much wiped off with a 3M scourer.  Really impressed with how well the previous owner maintained it. Bank account went down so quick! Service, then GB - managed to get a spanking new 34 genuine box from Nissan. All the rest of the conversion parts from Kudos.  Went with a Nismo short shifter. New pedals and Exedy Clutch and FW. Ordered the Prp Rear Main Retainer kit which should arrive Friday and my first engine mod part just like I did with my S15 will be the Tomei Expreme Turbo Outlet. Already on order. It'll likely sleep next to me on a pillow during the coming months. 🥰 Last build was on my JET200GT profile and on SAU and Hardtuned I had documented the build. Planning to try to do that again. Brands feel scarce now. Wish we still had ARC and Apexi parts readily available. Exhaust - need some advice on this. I had an Apexi exhaust on the S15 and loved the tone. My mate had a HKS HP Silent on his 33 and suggested I go with that to avoid drone. I can't remember hearing an RB25DET running that so will likely need to wait for a meet or something to hear it.  Not after big power, just enjoy building it, and drivability with minimal negative attention.

      I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
