Swapped manual gearbox from R32 RB20DET into ECR33. 1-5 gears work fine. But reverse gear can't be "fixed", it jumps back into neutral.

To move backward, I must engage reverse gear and fix it by left hand. What can happend with the gearbox?

ps. Sorry for my English, this is not my native language. ;)

Your English is fine ;)

Sounds like reverse synchro hub, could be selector too...I'm guessing your R32 box is second hand? Lucky dip with second hand boxes...you'll need to pull apart the thing to work it out I think.

Question, why did you swap the R32 box into the R33? Unless your R33 was originally N/A, the R33 turbo box is much much stronger and you'd be crazy to swap it for anything else in the Skyline range.

My ECR33 is daily driver and I don't planning any overboosting. And I think atmo gearbox will handle stock power levels.

But the problem is with the reverse gear. Don't know what should I do for now. :D

ps. Yep, the gearbox is from parted out R32.

It has probably broken the little spring that locks the selector into reverse.

2 choices - major expense to remove the gearbox to replace the broken spring. Or just put up with the inconvenience of having to hold it in reverse.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?

      You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.

      The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
