Hi Mate

i have 2 cars now for a while. a auto r32 gts4 and a old rusted out but modified r32 GTR. the gtr is very rusted so i scraped it for parts. i took the motor out for a s14 silvia swap. But looking closely i noticed a lot of similarities with my gts4 auto and gtr drive train set up. today as we speak i have the GTR gear box installed in my gts4 it fits like it was meant to be there.lol all the drive shafts lined up like the original ones do. i just had to cut the floor open for the gear sick to fit. in the morning i will move the peddles brake and clutch from the gtr to install them in the gts4. the slave and clutch master of course and see how it goes.

Seeing that the front and rear diffs are stock gts4 will i need to use the gtr's??? or will this be ok.

also can someone help me with the attessa system how do i bleed it up??? the reservoir is empty.

thank mate

There's a reason it all looks the same and fits. They're basically the same chassis. Only the panels are really different.

Keep the GTS4 diffs. People with GTRs actually want them to transplant into their cars because the ratios are shorter.

I can't help you with the bleed procedure, but I'm dead sure that it has been written up. Use google to search this site (and other sites obviously). If you use the tag

site:performanceforums.com in a google search along with the terms you are looking for you will only get results from that site. Works better than most forum search engines.

I've also posted the procedure before and am too lazy to find it again....but basically put the car in the air, out of gear, turn engine on, open the bleeder at the rear of the gearbox until the fluid runs without bubbles. Pretty easy. If you still get a 4wd light there is another bleeder above the rear driveshaft that you might also have to bleed.

thanks so much mate i will look for the links you mentioned. its funny cause i couldn't even sleep well knowing that it can work. lol

why do people look to run gts4 diffs that's funny. Do you mean that it makes for better et's in the quarter mile. (short gears)?????

well my friend you seem to be right cause all the dash look the same.lol my gts4 has a auto light built in the cluster do you think the gtr cluster will work as well.???? looking even closer it looks like if i change the truck lid and bumper the gtr rear lights would fit as well. i find this so funny.

its to bad i cant find a power fc for this rb2odet motor. i have made ok power years ago using a afc with hot wiring a z32 AFM with steel wheel tubro on a rb25det motor excluding other small mods. i cant wait to launch this car and feel the difference from auto to stick. lol.

I'm sure it will be nothing like my r33 GTR that smokes all 4's lol.

thank you for your time and consideration.

I'm not sure exactly what you mean about the instrument cluster.....they are basically the same across all the R32s. The GTSt didn't have a torque meter in the cluster, but the GTR cars did. I can't remember whether the GTS4 followed the GTR or the GTSt in that regard....I suspect they follow the GTSt....but it doesn't really matter. The tacho and speedo are all the same stuff. Same with the other gauges. The auto trans indicator is a separate thing. When I did a manual conversion into my R32 I just changed the cluster surround to a manual one to get rid of it.

Also not sure what you mean by the bootlid, bumper and lights. Is your GTS4 a 4 door? Because the coupes were all the same stuff up the back regardless of whether they were GTSt, GTS4 or GTR.

As to the question of engine management. Don't waste your time looking for a PowerFC. Visit nistune.com and buy a board for your factory ECU. Get it installed (Matt from Nistune here in Australia should be able to point you to a dealer/installer in the US) and you're away with fully programmable management in the original ECU.

interesting stuff guys. well i can conform that the the cluster is different, and that the auto indicator is in a different location. that was my bad guy's i just forgot where it was. well today i finished it up by installing the peddles and all. i noticed that the gtr has a clutch master booster and the fire wall was different with an indentation to accommodate it, but the gts4 didn't, so i ended up using a r33 gtst clutch master cylinder to get it all working. i understand now about the shorter ratios, and thanks niZmo_Man.

the gtr cluster is different. well i mean i can see it working but i would need to move around some wires cause when i put on the signal lights to the left direction the hicas light flashes, and the rpm's don't work on the gtr cluster. the physical dimensions fit. now all thats left is the transmission transfer case oil filling, and the attessa filling and bleeding procedure. oh and about the trunk lid. i was say that just the shape looks to be different on my 4 door gts4. but i'm thinking if i use the gtr rear bumper and trunk lid the lights would fit cause the only difference seems to be the inner parts of the tail lights are round, and the gtr's trunk lid and bumper looks like to would accommodate this difference. i thinking that the front bumper from the gtr could work to. i will look into the nisstune as I've always wondered about it. can anyone link me to a very good dealer in the us.?????? thanks again mate.

GTR front bumper goes on to the other Skylines easily enough. Google up someone's story. I'm sure some kid has documented it. It's not difficult.

There are plenty of 4 doors out there with 2 door style taillights too. So that can't be impossible.

Contact Nistune here in Oz direct. Matt will tell you who to talk to in the US.

its done. after driving the car. i noticed that the 4wd light comes on. any ideas. i bleed-ed the atessa system right and getting no air out now. i noticed that one of the front tires are different. its the same tire size but different height. one is 91h and the other is 89v.

One time i drove the car for a while and i noticed it stayed off and only came back in after i stopped and cut the key off to have a conversion with a friend. well i really think it's the tires. let me explain the rear ones are the same, but the two front ones are different names but the same size 205/50/16. would this cause the light to come on???? now when i get up i will change all the tires to the same size and brand (new ones), I'm just hoping that it would be the fix before i do the buy. i plan on using the r32 gtr rims they are wider, and with tires they feel way lighter, oh that's the factory rims I'm talking about. plus plus it looks so much better. I also went with the gtr fuel tank cause it plastic i noticed. witch i found interesting. i plan on installing the coil overs i got from the gtr alone some other items. like greedy boost gauge, HKS D Dragger muffler, seeing how the car is a 4 door i will need to lengthen the piping. oh and a FMIC, and Blitz BOV vented back in.

i would really like that 4wd light to go off and work right. is there a way to pull codes to see what the 4wd module is saying?? what if one day a speed sensor goes bad??? i would need to know how to retrieve codes from the module.

ok i just replaced all the tires using the gtr oem rims. the sizes are 225/50/R16 all round. but i drove it today and the light came on after about an hour of driving. i would cut the key off and restart the car and the light would go off, then after like 1 minute it comes back on. i would really like to know what approach to take to address this problem.

Now it may be the pump cause the car was converted to rear wheel drive and the pump ran for a while dry with no oil before the fuse was pulled. now i can just replace it with the gtr's pump. any ideas would help mate.

91h and 89v are the load ratings, not tyre height. Your two different front tyres may have been the same size, but just might have been different enough in rolling diameter to cause the fault.....even the same tyre, one new and one worn is enough difference. But as it turns out, that's not the problem, seeing as you get it with new tyres also.

ATTESSA computer under the parcel shelf has a flashing led for fault codes, or you can read them out through the Consult port with a decent scan tool.

GTSBoy thanks mate. i will look at the computer to get the codes. at least the parts that i may need would be right on that r32 gtr. i really did this swap to use the 4wd system so any help would be appreciated. i must say with the gtr's RS-R coil overs and fresh rotors along with the new tires made a world of difference with the car. i Love the way it drives. dropping the diff and changing the pump is no problem for me as well mate. that sounds like a 4 hour job.

to me i have the time as i'm not working right now lol. thanks again mate you the only one helping me out really.

The way you said the light came on after an hour of driving, then stop, key off/on and all good again sounds to me like the steering angle sensor.

Have you got an aftermarket steering wheel? That's the most common cause with the boss incorrectly aligned.

Car thinks you're turning a huge diameter circle and then after a while it throws a fault.

Most often seen when highway driving. (straight ahead)

As for the ecu, you've swapped over everything else from a GTR, may as well go for the Rb26 PFc too.

They're pretty cheap 2nd hand.

Mate go put the gts4 metal tank back in. It has a swirlpot inside the tank where the pump sits. Also get an s14 snub nose clutch master cylinder because you will want a 30 in that thing soon and will need to do this anyway. Also with the awd light coming on and off check the resevior in the boot on the right side and make sure the levels are right and also make sure you bleed the rear nipple properly. Also check that the piston in the gearbox for the clutch packs is engaging properly and make sure to check the 4wd fuse in the box under the bonnet of the lefthand side in front of the strut tower is in correctly and not corroding. The exhaust will be about 150mm shorter of the rear bumper then normal. Your auto cluster is different from a manual gts4 manual gts4 is the same as gtr. With the diff ratios yes bang on the gts4 is 4.33 and are very strong. Many have seen over 800hp through them. The tail lights from gtr will go straight in the just have a little over hanging corner. Also nistune is awesome forget power fc. The capabilities and system retention of things like knock are very important and when/if you go rb30 it can be straight up retuned for that too.

Hi there again. Well i ended up damaging the rb20. Lol. But i just finished installing the rb26 in my gst4. I remembered to use the gts4 front diff insted of the gtr's. I changed all the harness under the hood all the way back to the fuse box by the drivers feet. Two plugs were different so i swaped out the pins and only noticed that one wire out of the two plugs were different but i placed it in the same location.

The fuse box and the whole harness in the engine bay was changed over. Im now waiting on my top mount manifold to reach so i can finish up the intercooler piping and down pipe. Im also looking for a clear insructions on how to install my power FC D jetro map sensors. I think looking from the japanese instructions that i have to tap into number 3 and 4 cylinder throttle body with a little air fitting on both sides. Them mount the map sensors with the smallest hose possible. am i on the right path here. Then i have to hook up the signal from the maps to number 1 and 2 amf inputs on the ecu main plug. Is this right.

Thanks mate.

Sorry man but just use the stock rb26 ecu with the loom and get a nistunr installed. Lot less fking round and retains knock and is capable of over 400awkw. Pretty cheap too and constantly upgrading the hard and software vs dejetro which is becoming out dated. Just my experience and 2c worth from it.

    • 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.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
