What to UPGRADE NEXT!??

So I just bought a R34 Skyline GTT 1998 AUTOMATIC sadly.

I DON'T PLAN TO TRACK IT ! Just for Daily drive with a bit more Power & Torque :) 
so not planning on spending Millions of dollars LOL just a decent upgrade since it has some Performance already.

It features
- Full Apexi Exhaust 3" all the way to Turbo front pipe with High Flow Cat
- Blitz Pod Filter
- HKS Turbo Timer
- Brand new Tyres
- AfterMarket Coilovers

I also did a Full Major service including 
- CoilPacks (SplitFire), Spark Plugs (PFR6A-11), Water Pump (Genuine), All V Belts (Gates),
-Rocket cover Gasket (Permaseal), All Turbo Gaskets (PermaSeal), Timing Belt Kit (Gates)
Radiator Flush & Oil Change with Filter with Castrol & New Battery (Century)

Car is running Great but being in other cars especially them "Hondas" and also my N/A R34
it feels weak and lack of power so therefore I'm seeking in upgrading bit by bit

I don't want to spend a lot all up because I'm now officially broke LOL


Just want to get opinions on what to Upgrade next

Ideas : Bigger Turbo (Direct Fit prefered), Injectors, Fuel Pump, ECU, Cams, BOV etc
Tell me what brands for the part too if you could please :) 

I heard finding a ECU for Automatic is hard or not recommended, or is it possible and if so what brand ?

How tough are the automatics in these? Really don't hear much about them.

Most basic autos with some miles don't seem to like a bunch of power added and start to slip. However a skyline auto is likely much tougher than the auto's I've had experience with.

Well I looked up and said that the Auto gear box can take up to 200kw which is as good a guess as any other number and it could shit itself with more or less than that, anything above I will have to upgrade the gear box for more performance. It's a trip tonic so it's really no different to any previous Jatco slushbox that you could change by moving the lever and which is the quickest way to wear them out anyway.

Fixed your post.

That is correct, I had 200rwkw wit my R34 auto and it was fine. At 257rwkw it wasn't and started slipping bad plus the bigger turbo was off the boil for most of the time so very laggy and s--t drivability. I converted the car to manual and it's night and day with the same turbo, currently at 275rwkw.

My recommendation is to install Nistune, a boost controller and supporting mods and tune the car for the max boost the stock turbo can make. This makes a drivable 200rwkw that is responsive and still fun in the auto.

Beyond that you need to build the box plus probably high stall or go manual conversion. Gets expensive quickly.

200rwkw can be a more fun that 275rwkw if it's more accessible.

My 3 rules of upgrade:

1. Make it STOP. Maybe fit some braided brake lines, slotted rotors, decent pads

2. Make it HANDLE. Swaybars first, then decent shock absorbers, then heavy duty springs

3. Make it go. However, if 1 & 2 are successful, you probably don't really need 3, especially if you aren't taking it on the track

lol!! but hey they have paddle shifters on the steering wheel man...paddle shifters!!!

but yeah as a auto-skyline driver myself, OP here's what you should do. Don't research any more, don't listen to anyone else, just take my words as gospel.

Get a hypergear hiflow turbo. If you hit R&R/fuel cut then, an SAFC neo or nistune, to avoid this pain. Get a shift kit to make the most of your tiptronic. Get a cheap return flow FMIC, eg Cooling Pro from justjap. Get an electronic boost controller, not some gizmo ebay shit that you can't figure out wtf is happening with it or the buttons are so sketchy you can't even set the damn thing. I suggest greddy profec b.

Spend the rest on a brake upgrade, some chassis stiffening, and every suspension arm/upgrade available.

From there if you decide to chase serious power and spend $$ on the car, then you haven't spent toooo much on power upgrades you're now going to supersede, and still have a sorted chassis/suspension setup.

^^^ Good shopping list. That said, what's that all up, 3-4k + labour + tune?

So with all new parts + workshop labour & workshop tune you're looking at not far off the going price for an older automatic R34 GTT.

Not sure how that'll work if you're broke, ain't a cheap game...

If you're saving up for an R35, I'd avoid spending money on your current car.

Put an automatic transmission cooler on to increase its lifespan.

Off topic, what's worse than automatic "triptonic" paddle shifters? CVT simulated gears (defeats the whole purpose of CVTs, unless you're engine braking downhill I suppose).

Golf GTi with basic basic mods would destroy a mild GTt GTSt on the straight, around corners and even at picking up the slarts...

Yes Golf R over the GTI, but I did say price ascending order lol.

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
