Hi

So I've searched and cant find a repository of all questions relating to modifying an auto skyline(closest thing is auto performance thread which hardly anyone ever replies to and is mostly about figures and specs)

I think it would be helpful for all auto skyline owners to have all their questions answered in one thread...

The usual questions :

- Can someone post their standard setup in an r33 s2 auto - computer management , injector size , fuel pump type, transmission cooler type , high flow turbo , valve body mods other mods etc. and power output

- How much can a decent condition auto box usually handle before it goes boom?

- Is a transcooler is all that is needed to ensure longevity for a car running below 250rwkw?

- Recommended workshop in Sydney to work on Skyline auto tranny's?

- Recommend a transcooler that did the job , good quality and easy installation

- What size injectors are usually used/needed with BPU ( fmic,exhaust, high flow turbo, fuel pump). Will there be any issues with tuning if going to large (would 550cc Nismo's suffice?disdvantages going with 1000cc's?)

- What computer management can we auto guys use? I know standalone is out of the question , is the eManage adequate? What about the SAFC2?

- Am I better of going with an eManage as opposed to getting the ecu tuned my Toshi

My Goal is to get a reliable 240rwkw at about 16psi on a high flowed r33 turbo with intake/exhaust, injectors , fuel pump and emanage.

With a shift kit and trans cooler you should be good for around 300kw, other than that the normal supporting mods apply, but you will need to aim a little high, the auto will suck 10% or more of your power output when compared to a manual.

Considering you would need to buy an Emanage Ultimate, plug in or universal loom, map sensor, wire it in then get it tuned, I think Toshi might be your best bet.

No idea, I am in Melbourne. I could suggest a few good places down here, but obviously you will need to search around Sydney for a suitable trans specialist, or simply fit an MV valve body yourself.

Trans cooler- any large (V8) cooler from Autobarn that fits, and has the same barbed connections, 8mm I think.

The other questions are better answered by your tuner, or Toshi in this case. There may be limitations to the stock ecu. Other than that, Bosch 1000's are cheaper than Nismo injectors. (and there are plenty of fake Nismo injectors getting about.)

Pump, get a Walbro 460L at $200.

I destroyed a MV auto box in about 10,000kms. However this was a n/a box that was built up, not the turbo version. They said this is the same but it is not. (For the r34).

I have an aftermarket transmission ecu and a haltech ps2000 for the engine.

Dunno anyone in Sydney - I sent my entire transmission on a pallet to SA for it to go bang when it came back ;). MV can send the items to you or a mechanic though. The actual assembly of the auto transmission is 'easy' - any transmission shop can assemble it and the MV guys are easy to talk to.

I recently installed a Davies Craig Hydra Cool Transmission Cooler (Part No: 678), read more here: Auto Trans Cooler Upgrade

Easy install (although you'll need to remove your front mount first) and seems to work well.

ended up buying this for $139 at supercheap

Got my rocker cover gasket kit from kudo motosports (lol all the usual r33 failings have befallen me - coils went - replaced with splitfires , exhaust manifold studs snapped - replaced with uprated toyota ones ....and now my cam covers are leaking....)

Also got a walboro gs342 pump from kudo with kit.

Going get a service , coolant flush and replace the plugs , should be good enough for Toshi should tune after all of the above is installed.

Does anyone know that if i would also need to get the rocker cover washer set as well for $99 as the fix for the usual cam cover leakage that the rb25 suffers?

Everything toyota is better lol, higher quality materials used. My nissanhead engine builder mate even agrees. Broken exhaust studs not common on toyotas but seems expected on nissans after a while.

*easy to replace

Why are the Toyota studs better? The nissan ones lasted a fair while!

I wouldn't worry about the rocket cover washers. worse car scenario they are ready to replace at a later date.

The toyota ones are rated as much stronger, the Nissan ones did last a fair while but the ones I put in will last the life of the car. Well Id prefer all oil leaks to be fixed before I do any sort of tune.

  • 3 weeks later...

Ok guys , need some advice....

Should I :

1. Go with the Toshi's road and dyno tune (just with a front mount , pod filter , fuel pump and boost controller) for engine reponse

OR

2. Buy a high flow turbo , buy z32 afm and buy 550cc injectors and then get Toshi to tune.

Would it be better for me to buy these parts first and then get Toshi to tune a bit later on or to not buy injectors or afm and just do normal tune with him?

Disadvantage with the second option is that I would have to wait another month or two longer to recoup funds but at least then I dont have to tune twice!

Don't do something that needs a tune, then drive around while you save up. Save up what you need for the physical work AND the tune then do it all together.

Oh yeah , id never do that. I did that with my last car...biggest noob mistake ever. Built engine - TRD cams, honed bored , MHG etc and then ran the stock ecu like an idiot. Spun a bearing in under 1000km

More importantly, best tuning options? Want to go above 220rwkw so Safc is not an option and to use emanage you have to remap the ecu first- so have to remap ecu - buy emanage and then tune emanage - quite an expensive exercise

Toshi only has manual ecu's left....he seems like he knows hes stuff though so I'll be buying all the parts and hold of installing it until I can figure out what kind of tune to do with him.

    • 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"
