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.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 😃

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.
