Long story short I got a blown rb26 collecting dust in the garage and a rebuild 25 at the machine shop atm, I'm looking to put the 26's cam cover on the 25 but I noticed that on the Rb25 Head the oil baffles over the cams are on the 2 last lobes in the back of the head rather then the 2 front on the RB26. This makes sense because the rb25 stock covers pick up the air in the back of the cover and the 26's picks up in the front. Now my question is, should I relocate those oil baffles to prevent oil from going back in the catch can !?

Would make sense to do so but just want to check if some one has gone down that road and can give me some advice

From my research you just use the hose's as they are on either set of covers, two problems you will have, if you use the standard cross over rb25 manifold the drivers side cover will hit the throttle body and the front cover (which is essential to get the smooth look of the 26 covers) will not fit over the cas, you will either have to enlarge the hump in some way or cut a hole for the cas to come through.

      I’d love to find some where that can recover the dashes to look brand new and original. Mine has a very slight bubble, nothing compared to some I’ve seen though

      $170K. I asked one of the guys there as a joke if that price was just for the passenger seat as it was where the price sheet was... he tried really hard to crack a smile 😄 He also mentioned that every single part of the car was inspected and either restored or replaced with a new or as new part, or made from scratch. The interior was incredible, every inch like a new car.

      Time for a modernisation, throw out the AFM, stock O2s, ECU into the e-waste bin. Rip out the cable throttle, IACV, pedal, etc. into the scrap metal bin. DBW, e-throttle, modern ECU, CANbus wideband, and the thing will drive better than when it left the factory.

      I agree, don't go trusting those trims. As I said, first step is to put the logger away, and do the basics in diagnosis.   I spend plenty of time with data loggers. I also spend plenty of time teaching "technicians" why they need to stop using their data loggers, and learn real diagnostics.   The amount of data logs I play with would probably blow most people away. I don't just use it to diagnose. I log raw CAN data too, as a nice chunk of my job is reverse engineering what automotive manufacturers are doing.

      I'm aware, but unless you're actually seeing the voltage the ECU is seeing and you're able to verify the sensors are actually working I find it hard to just trust STFT/LTFT. I will say, logging the ECU comes naturally to me because it's one of the lowest effort methods of diagnosis and I do similar things in my day job all the time. Staring at 20+ charts looking for something that isn't quite right isn't for everyone. NDS1 allows you to log almost everything so that's normally what I do and then sort out the data later.
