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.

    • Thanks Dose.....    I appreciate it!!
    • I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.
    • I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.   
    • Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head. (me)
    • Ha ha ha, so they stopped the bearings spinning on the one you want, but then decided the crank hub should slip instead 😛   Stick to RB, at least you can work on it yourself. And now it doesn't smell of vapour   Also I still believe there's a chance your new flap doesn't "pop", as even though the engine might breath hard, it has a direct path with no restriction to the inlet, which when on boost should pull a bit of suction for you. If you do get pressure in the catch can id be very intrigued. Time to put a boost gauge on it, and a session at the track, then solid cover your vent and do another session
