rsx84: I haven't bolted the cusco down properly yet, but it looks like sweet f***all! :D

Don't know about r33 calipers fitting, im not sure if the mounts are the same, and they are bigger also. Also be aware that most wheels dont fit on after this conversion, i have 20mm bolt on spacers

I have a vg30 on the rb20, and i have a vg30 turbo on my rb25 in the r33 i had, they work a treat, only a small difference on the rb25 tho :)

hmmm no go on the sensor thing...thinking the timing is out

hoping anyways....

anyone got a workshop manual for an rb20?

oh and anyone wanna buy a vg30 turbo....?

how convenient, im looking for one at the moment. hows the condition on that

sucker? and what you askin?

crimmo: try InjectMaz for wiring. i know he's done a 30 to rb20 before and he can often beat or match prices but the best thing, he can come to you if you ask nice. pretty cheap for cash too...

also, im still in the dark with these calipers... should i get em and try, i mean if they dont fit, they can be made to fit without too much hassle, so it wont be a total waste? oh yeah, crimmo, what discs you using at the back?

anyone know the size of dr30 rear discs, the DBA thing lists something like 258 but apparaently thats wrong...

Initially, an RB20DET/HR31 gearbox and final drive 4.1:1 R200 Mechanical LSD with Cusco centre, approx 70/75 lb pre load, mainly due to having the Jenesis 260 kph Speedo.

If it doesn't handle the power, which I am expecting to be the case, I have an R33 GTS 25t gearbox as backup, but with this gearbox comes a couple of minor problems, the most primary being it's speedo drive; IT'S ELECTRONIC and am yet to work out how I can convert the electronic drive to an analogue speedo. If it can't be done I will get an electronic dash cluster assembly and sell off the 260 Jenesis Speedo.

DR rear are same as Z31. 290 x 10, but you will need DR rear trailing arms for them to be bolt on.

As for the front calliper mounts, I was told by mates in Adelaide that MR are about 88 mm spacings, mount bolts centre to centre, where DR's are 100 mm centres.

Mike, send me an email or private message and I will put you in touch with a guy in Adelaide that has done it already, or at least looked at it.

if you use the speedo cable from the gtr its not electronic and has been used by a few r31 boys with the same problem!!

I got your drift!

Bit slow today.

You mean use the drive assembly from the GTR, to convert back to cable.

I try.

looking at 3 hundy for the vg30 turbo.

bought it looking for big power....no just want to get my shitbox going so need the cash

nothing wrong with it, even went to the trouble of buying new banjo bolts for it.

i mounted it up to my manifold, fitted like a franger, didnt have the right outlet elbow tho

pm me if anyone is interested.

as for the workshop manual its ok im going to buy one to sort it all out, thanks tho.

Anything is possible. Just that DR30 not HR31 struts would make it a whole lot easier.

A fair bit of fabrication is needed otherwise.

Hi guys-thought I may be able to assist a bit.As you know,the DR30 has bigger brakes than the HR30,so diferent mounting holes,etc.I've had no experiance with MR30's,but believe them to be close(or same) as HR30.

DR30's have the 100mm mount hole spacing.HR31's(Japanese Skyline) also have 100mm spacing.

R31's(ausie) have smaller spacing,same as HR/MR30's.

R31(aussie) GTS have same struts/mounts as HR31's.

Type m and GTR 4 pot calipers have 100mm spacing.

Hope this helps (somewhat) :thumbsup:

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
