Hey team. 
 

I have recently bought a broken RB25 that I’m going to rebuild to replace my 20DE neo in my 34. 
 

It has 75T stamped on the block and head. From research I have found it’s out of a 33 but have various results whether it’s a DE or a DET. Did Nissan use the same block and head for both and if so how do I tell what I have and if a DE what changes would I have to make to convert to +T. 
 

Thanks in advance

With plugs though? Not the actual drain fitting?

Yep, the openings were plugged, but I rebuilt a DET using one DE block and swapped the fittings and other internals in. The factory had not left anything blanked or undrilled, although I have seen R34 N/A 75T blocks that did not have the turbo oil drain drilled and tapped.

75T Is defiantly a series 2... I have successfully done a fully forged and built rb25de + T NEO conversion on my r34 as well all of the necessary supporting mods. Message me if you need any help or advice. I can also link you to forum threads with lots of useful information that i learned from.

You can use the coolant drain plug as water feed and the nipple off the thermostat housing as water return.
For oil... you can use a brass "T" between the oil pressure sensor and block as feed and for the return, it is very simple. its the plug where the DET drain would be. but on the NEO rb's , that plug wont be there and  you will have the head drain plug (same size) approx. 6  inches infront. Check out the topic on this forum called "doing a plus t on a unopened rb25neo". you will learn 75% of everything you have to do from there. the rest you can figured out or you can easily get your questions answered from searching the forums here or by private messaging guys like @DatsunBanana @NEO25T @Rusty Nuts and myself included

      R32 gtr hood latch support/lock part number search

      By joshuaho96 · Posted

      65601-05U00 is the hood latch. 62550-08U31 is the support that holds it to the radiator core support. They are all super discontinued so I don't really have any great leads on how to source this stuff.

      GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.

      R32 gtr hood latch support/lock part number search

      By eli995 · Posted

      Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan)

      Stock rb25det neo questions

      If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
