The S1 Dayz I have is atm an auto, 4WD. I toyed with the idea of going RB30 but I have been given an RWD, rebuilt RB25DET, Skyline motor. There are no mounting points on this motor on which to bolt the front diff. So I either change to RWD or rebuild the blown motor or get another 4WD motor. Personally I like the 4WD. But------ if I go RWD will i have to change the ecu? Or just leave the front axles out and pull the 4WD fuse?

And I am not sure that the Skyline RB25DET motor is entirely compatible without having to change a lot of stuff. For instance will I have to change the ecu?

Any advice greatly appreciated.

Sounds like way too much effort for an average result.

Sell the 25 and put the kesh towards rebuilding your 25 or going a 30 with your existing gear.

Did you get an ecu with the DET? Your n/a ecu will not work for the DET. And you have to find a way to stop your front wheels falling off.

I don't think there is an easy solution.

Do you know if the DET has been rebored? You could maybe pull out the DE and rebuild it with parts from the DET. You might also need a new loom as well as an auto DET ecu and if the DET already has the turbo, bov etc you would just need an intercooler (and maybe some better brakes).

I reckon a rebuild of your current donk is likely the easiest solution. Not a full on ZOMGFORGED type build, but depending on how "blown" the current set up is, a set of slugs, maybe rods (although I'd be surprised if they were required) and a good going over to check the crank and block.

      Yes, it will take a fair amount of solution but the sodium citrate + citric acid + detergent is cheap stuff. Use laundry detergent instead of dish soap if you want to reduce the bubbles, also you could just buy sodium citrate and add some citric acid to the mix until you get to a weakly acidic solution if you don't feel like dealing with all the bubbling generated by adding everything together. For a fuel tank you need quite a lot of distilled water but it's probably worth the effort.

      Everyone I know with a90 supra at time attack aren't having issues with 3-5 fast laps so far and one is decent powered one too. Saw a k24 swapped 86 with a 8hp70 and big slicks and aero which had no drama's at QR and Manton Park. I've stuck a 25 row cooler in my setup with 8hp45/50 in the hopes of keeping the oil cool as I plan on some racing next year that 20-30min sessions. I've also geared my car so won't be using 7th and 8th gear too. @Dose Pipe Sutututu just needs to get that samsonas in already and have that tassie guy fit a head and rev it too 11ty thousand rpm.

      Mistakes were made, my R34 Story

      My embedded systems thoughts have me sitting with GTS on this. Variation between same phone hardware, should be small. However, the internal "intensity" or "volume" amount that say Google passes to the app, will be quite different, as the underlying hardware will be passing different levels for the same volume to the Google OS. Until the app creator has had each individual phone, and set benchmarks and calibrations for each, the amount of error can be quite huge.   It can even be observed by using different phones, recording the same noise, and then playing it back, they end up soon ding different. A big reason for it, is even the different types of mics used in phones have different responses, and different frequency ranges. Then you need to get into the DSP, and the variations in those, their sample rates which then effect their frequency range, and then the quality of the DSP, and what type of hardware conversion they do to for the ADC within the DSP. Oh, and let's not forget at the low level phones are designed to cutout loud sounds. It's one of the reasons they suck in really loud environments (eg concerts). The louder you yell, the more you'll get cutout too Note DSP is Digital Signal Processor ADC is the analogue to data converter. I don't have any real data on what the variation would truly be, however, chat GPT says in general, their output is typically between +/-2dB to +/-5dB of what you're really measuring. So realistically, anything from 4 to 10dB variation is possible even with the same devices.
