RB20/25DE longer than RB25DET gearbox

I'm gathering parts for a manual conversion on my R34 25GT. I know the RB25DET box is physically a lot fatter and stronger but in some side by side pics on the web it actually looks a little bit shorter than the RB20/25DE box. There's also a pic out there of the 25DET box with a tape measure against it showing about 32 inches and the 20/25DE box I got already is more like 33 inches. Does that sound right that the weaker box is actually a bit longer?

This info is to help me buy the right tail shaft. It would be equally useful to know the actual length of the propshaft front piece from an R33 GTS or R34 GT. Anyone got that info?

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By tsuokun · Posted

      Throwing my spoon to the soup here a bit.  When I installed a 044 back in 2012, along with the direct power mod, the car became very difficult to start. To a point I burned one starter motor as I was late for work and tried to get the thing going. With some tuning and careful use of gas pedal when cranking it became bearable. Trying to make this short as possible, but the 044 died after 2-3 years, after which I went with an AEM 320lph pump, which also died after about 4 years to my dismay. After that I went with a Nismo pump, and while trying diagnose an emissions problem, I noticed for the first time that my fuel pressure was 5bar/72psi on idle, and that removing the vacuum line did nothing. After monitoring the situation, and removing the direct power feed and going back to FPCM in attempts to remedy it, I noticed there was fuel in the pressure regulator vac line. Kept the FPCM, installed AEM external regu and the car became sooo much better in every way, including starting. And I had driven it like it was for 11 years.. Anyway, I agree these are likely two different problems, and the FP problem you just haven't noticed before. I do not know much about haltecs, but what first came to mind was the CAS, which probably is not there any more. So how is the wiring from haltec to gauge cluster? How is the battery voltage and alternator?

      Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)

      +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
