Hey all. My first post on this forum, but i have been involved with cars, and forums, for a while. I live in the USA and only recently have Skyline R32's become legal to import. I purchased a 91 GTS4, but its auto and i would like to convert it to 5 speed.

From the info i gathered, I know the GTR box will go straight in. I just want to verify my parts list. I have yet to find a definitive "YES THATS IT" list anywhere verified by someone with experience.

GTR Box

Shift boot

Clutch/brake pedals

Clutch master cylinder

Clutch slave and lines

Clutch/flywheel/flywheel bolts

Manual Spigot bush

Manual Sandwich Plate

I have a few questions.

Are the RB20 manual sandwich plates different on the gtst and gts4/gtr? Also, what is this thing? Im going to assume it gets sandwiched between the engine and tranny. Correct if wrong.

The cross member is the same? (R32 GTR tranny going in if it matters)

Provided i connect the needed wires in order to start the car, the auto gts4 ecu will work.

Also if i missed anything please tell me.

Hi, I Have a 1993 A31 Cefiro SE4, i have done the Conversion, Your Gts4 and my SE4 are the same, So i can give you some pointers, The R33 GTR gearbox has better gearing, your original sandw plate will be fine, The only difference is the standerd plate does not have the half shaft cut out,The gtr half shaft is a bit bigger than yours. your auto drive shaft should or will bolt straight back on, mine did, The Oil feed lines will bolt straight back on to the gtr box, Change all the oil for the whole 4 wheel drive system so let the rear feed line drain, it will empty the pump on top of ya rear diff and ya oil container, mine is in the boot on the right side,Also the front diff and clutch plate OIl. Leave the speed sensor disconnected, you can connect the reversing light switch i think its the same, I think there was a bit of modification on the rear gearbox mount, Sorry i cant remember that one, Use a 10in Clutch and pressure plate, I USE THE PULL STYLE CLUTCH, Stranded gtr , Its has been good, It has let me down twice on super fast take offs ive spun it but its all in the way you let it go with the throttle, i dun the spins in the first 6mths after the conversion , have dun that for 4 years or so, I also change all my gearing to 4.1 as i want more mid n top end for the open road,250ks check my listing to see the other mods i have done, Oh yeh when you re oil the pump and lines to.to the rear of the g/box is were you bleed it from, Mine took ages to get pressure again but it kinda the norm, Mine has been working perfectly since, but that oil is 20 odd years old, e this burble will help you, Jamind

    • I was using the wiring diagram I have So 12.74V is coming into the rear Fuel Pump relay as I measured.  When I turn the key to ON im getting 0.6V to the Fuel Pump plug; which i assume is backfeed voltage and doesnt include the 12V from ignition power.  The rear relay is working and being triggered.  From the diagram I clearly see the rear relay 80 = Rear Relay going into the Body/H loom (R-27) 27 = Fuel Pump plug going into the Body/H loom (T-20) 40 = Short Connector (R-27) I'm reading 12.74V on the blue/black wire which is the power for the Fuel Pump   From this diagram I can see the Ignition relay goes into the front and up to the ignition  2 = Fuel Pump Relay <1M> (R-27) 37 = ING Relay <1M> I started from the pump using this reference Which the way I read it (referencing Nissan wiring color codes) is: Pin Wire Color Function 1 B/P (Black/Pink) Ground 2 L/W (Blue/White)        ECU Trigger 3 SB (Sky Blue) Fuel Pump 5 L/B (Blue/Black) 12V Constant Tested SB to SB on Fuel Pump for continuity - confirmed Tested negative on Fuel Pump to 12V battery and L/B - confirmed 12V Pulled the relay putting 12V between Pin 1 & 2 and testing continuity on Pin 3 & 4 - confirmed relay   So that has me looking at this part of the circuit to understand whats happening here...and im still confused. From best I can tell; the disconnect is back to my previous diagram; between Ignition Relay and Fuel Pump Relay...which yet again; afaik is where the immobiliser should.    Thats what I was trying to explain to GTSboy; im not trying to fix it myself; yet I seem to have to get a Masters in Electrical Engineering (while im busy doing my actual job of DevOps & Cloud Engineering) somehow.  I just wanted more expert opinions; or more so that what I tested is correct and proves it to something around that area; to go back to the alarm tech (for a 3rd time) that he needs to fix it. He keeps telling me its not the alarm. He lives on the complete other side of the city so i understand not wanting to make a trip but as I said before if its the alarm it should be up to him to fix it. But he's adament its not; even though I pointed out the FP was immobilised through the original alarm. To my mind; it seems that the ECU is sending the signal; but the ignition is not getting 12V down the line.       
    • Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.
    • I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?
    • So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you  
    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'
