So far i just know that the R32 RB25de and R33 RB25de came with the 5 speed auto. I'm not sure if all of them did.

My HCR32 has a 5 speed auto.

It has 3 gear selections on the shifter and then 2 other gears on overdrive.

The overdrive sucks because when I'm driving Miss Daisy in the back and select OD after 80kmh, both 4th & 5th gear shift within a couple of seconds and the next thing I know I'm doing 80kmh with the engine turning at 1500rpm - needless to say it's pretty bloody gutless down there in that rev range. But when I'm on her she'll swap into 4th at 150kmh and 5th at 190kmh.

My only real bugbear is the inability to select 4th and 5th at will, which is why I'm in the middle of procuring everything for my manual conversion, no more auto for me.

I saw a five speed in a non turbo rb20de R33.... 4 door.....

I thought it was very strange as the dash in the 33 has the gear selection lights it had 1-4 then drive... a normal auto r33 had 1-3 then drive...

I dont know where youd get that info other than nissan japan... I have only ever seen one myself and i was confussed... I spoke to the guys in our auto devision and they had never seen one nor did they have any tech info on this box....

Yeah putting a manual box in a standard auot is a good thing...

I did it in my old GTSX.... The diff ration is taller and makes for a faster acc but lower top speed... But top speed is not important at QLD raceway nor on the strip as you will never reach red line top gear..... So yes this is a great idea....

Nissan had the 5-speed auto transmission designated RE5R01A, it's sister to the 4-speed, the RE4R01A and was used in both the Skyline series and the 1999 Q45 4.1 V8 Infinity, although there are other vehicles, I can't remember exactly which ones.

The manual coversion is going to be a wait and see as the gearbox I have coming is a Nismo close ratio, so the diff ratio may be a bit extreme for the box, should be fun for a while though!

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
