I know this has been thrashed around here a lot, but is the 20det good for up to 300hp?

Input shaft bearings don't like lots of torque. Your typical boosted RB25 is too much for it. I wore out 2 of them on an RB20.

They are about $1k.

Yeah, even that's no longer true. Anything at that price will need the other $3k spent on it!

Exactly. There is not much in between. R33 GTR gearboxes are cheaper, about $2k. But a lot of mucking around making them 2wd. Even a 350 2nd had box is $3k. I know this has been thrashed around here a lot, but is the 20det good for up to 300hp? They are about $1k. Like I said, don't intend to thrash it.

Hi mate I’m just about to do this to my r32 using the 08 d22 nav box (yd25ddti box)with an r32 rb26 bell housing gearbox was $900 and the bell housing was $400. But it is shorter by about 30mm so driveshaft needs some work but for a $4500 gearbox it’s good money spent to get a big box and something that is just over 12 years old. 20det boxes are over priced for used 30year old parts but will let you now how it all goes as I’m doing it.

cheers

Hi, Do you know what you have to do for this to work. Like do you have to disassemble the whole gearbox, to get the input shaft out and machine it?

Just Jap, JDM garage etc. The boxes from somewhere like Amayama or Nengun are way under $3k AUD new but you gotta ship it and duty, taxes. If I were to be getting a new one I'd be talking to Darron at Just Jap.

Forget the RB20 box idea

So I heeded your advise and hunted down the only new one I could find. That was at Alpha Omega Racing. R34 RB25DET Gearbox Price: $3,376.00 I have to admit that it is not a terrible price. But I was quoted $1,326 to ship to NZ. Total of $4,702. I only paid $3,000 for the car, so yeah.

You can look where I told you look and it'll probably be $500 - $1000 cheaper delivered. Nengun is under $3k. More to the point is why do you feel you need another box again ? You have an RB20DET box yeah ?

I am an idiot. I thought I had checked Nengun. Thanks for the reminder. You know when you have like 50 tabs open.

They are much cheaper. NZD $ 2,502 for the box about there is an option for $795 shipping. Now I am seriously looking at this. The best I can find locally is a RWD converted R33 GTR gearbox for $3,000. That is what I mean by stupid prices.

My next question, which I have asked of Nengun, is what other parts do I need to add it. I think it comes with a pull fork and thrust bearing. No speed sensor, clutch, slave, shifter. Looking at the pic on the site the part number 32010-AA520. 

https://www.nengun.com/oem/nissan/32010-aa520

It looks like I need to source the brackets and hoses etc. 

I am doing an auto conversion. I was looking at putting in a 20DET GB, but it seems that is only going to end in pain.

I ended up buying this one.

https://www.rhdjapan.com/nissan-oem-5-speed-manual-transmission-er34-rb25det.html

I have just taken delivery of it. With the current exchange rates, shipping, and GST, it came to about $4k NZD. Shipping took only 14 days once they had it in stock. Delivered to my door. But I did have to wait about two months for it be in stock. It was fine, as that was roughly the date specified when I ordered. What you see on the website is exactly what you get, pull clutch setup. OEM parts to convert come to about $330 NZD. But I got a Nismo pull clutch to go with it (on top of the $4k)

    • VCAM requires a special intake cam in order to be able to actuate the cam phaser. So you are limited in your selection there, usually you want to match your intake and exhaust cams to some extent. Turbo engines are not the same as naturally aspirated engines. Once the engine is on boost it matters less if your VE is tailing off when you can just increase the boost solenoid duty cycle to compensate. Most turbos also have significant backpressure which can favor less valve overlap than you'd expect at high RPM compared to an NA engine as the pulse tuning effect of exhaust runner length is competing with the exhaust backpressure causing internal EGR. It's likely that these effects are why the factory exhaust cam is said to be lower duration and lower lift than the intake cam. I would love for there to be public data comparing the effect of staggering cams in either direction (more duration on intake vs exhaust and vice versa) for the RB26. As far as I can tell nobody has done it.
    • 👍 I've got the conversion the Estonian guys on ebay, I guess there are other ways to contact them but all roads probably lead to the same people. I was a bit dubious about sending that much but they were quick and it works perfectly, the only thing I'm not impressed with is the english buttons they supply aren't a great match colourwise to the stock ones I did the install based on the US MY51 Q70 2013 manual, close enough to work out how to pull the console apart without breaking anything and the unit is direct plug in. Some functions are lost like the passenger parking camera and the japanese lady yelling to tell you how to parallel park. Frankly, the frustration for us with the jp menus was since Kel and I share the car, memorising the path to connect audio and then phone every time we change drivers was a pain. I've got a thread on my fuga here:   
    • Duncan that worked! Thankyou!    I pressed the (google translated) button of ‘current location’ then ‘TV-AUX ‘ and it worked. Wondering who did your conversion?
    • So you've found a bunch of info, or you found nothing? You're not being clear. It seems like you have a lot of reading and searching left to do. You need to ask specific questions for people to help you. If you haven't found answers to your questions, then it's likely that no one else has done it and you'll be a pioneer.
    • Drill holes in the muffler or put spacers between the joints for similar effect.
