Hey forum what's up? If I didn't say it before Happy New Year to all! Now down to business, I need to know if the injectors out of an 89 300zx will swap directly into an rb25det. Someone wants to sell me a set but, I am not sure if they will drop right in. I am thinking no but, I just need confirmation as I am unsure. Thanks for your help in advance.

Im pretty sure its only the later 300zx that has the same injectors as rb25... 95-96 from memory

89 was the first year Z32's came out so it's still possible that they are out of a Z32.. VG30DETT engine.. there may be some overlap though and they may be out of an 89 Z31 with the VG30ET engine.

Yep, the S3 Z32 sidefeed injectors should fit fine in a R33 RB25. They are 370CC stock for the TT ones. A lot of aftermarket injectors for the Z are the later model ones though, so if you are looking at a set of 740CC Nismo's then they should fit in fine.

Z31 are top feed.

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
