just wondering what turbo would be best on a auto r33 25t

i would like a turbo that kicks in the low rpm towards close to redline

because auto wont even let me rev it close to redline

it just changes gear on its own

any auto SAU's that has had experience with this problem?

i was more looking into a HKS 2530? kicks in at 35k rpm

I have a 2535 on my Auto R33, its a great turbo, peaks around 6500 with

tons of midrange, only a few hundred RPM more lag than standard turbo, you can barely feel it

I have that same problem atm though, sometimes after a few runs, the auto gearbox just shifts earlier and earlier. I have no idea why. So I get a great first run but it just gets worse after.

yea I have a transcooler and valvebody upgrade

didnt solve anything, during the install changed the fluid, and filter

problem still there, Im trying to install oil temp gauge to keep tabs on the auto box temperature, but having problems finding fittings for it

I cant imagine what your new RB30DET is going to be like with the 2535,tow a road train.

Recommend a highflow, There are two types, GCG do one with a BB cartridge, retails for around $1650, The other is a new bush bearing cartridge, Retails for around $1350. You retain standard plumbing & ducting.

Have done this upgrade on a couple of customer cars and they retain similar boost threshhold but pull right through revrange. your auto issues probably warrant a full manual valve body. Do the turbo upgrade fist, and go from there.

i have a r33 turbo on my auto 32gtst. + SAFC

no problem pulling to redline.

the problem was it wasnt changing quick enough before redline and therefore just hit the limiter.

this problem will be solved very soon as my g/box is being rebuilt much much stronger

at what rev does the gcg hi flowed turbo's kick in?

is there any site to help me on this?

i was more thinking on hi flowing but last thing i want is a laggy turbo that goes off for a bit then my car changes gear... no benefit at all

aquariuz6 - you have posted a number of threads in the past month.

In each one you are asking something totally different, or very similar questions

You need to set a goal and stick to it

Then read the RB25 Dyno Sticky and see what works for you.

If you then compare the turbos yourself, and plug that against the goal that you end up deciding on.

Im not trying to be rude or anything, but we cant really help you, if you cant decide and then stick to it.

As RB Power said, you have an auto, if you get the right convertor you wont loose bottom end as much

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
