On the topic of rb25 turbos. Is there a difference between the s1 and s2 turbos? i was at an importer today having a look and there was 2 'rb25' turbos there. One looked smaller that the other. The other one looked to have a larger rear housing...

Oh dear. Search is your friend. Type in "r33+ S1+ S2+ turbo+"

S2 and S1 are the same except that the S2 have a lighter impeller wheel than S1 (slightly faster spooling)

.. only the 34 neo turbs have bigger housings i'm pretty sure (vg30 rear)

r34 neo turbos use a plastic or nylon wheel ... the turbo is fundermentally the same as the r33 turbo no larger housing

R33 series 2 and R34 GTT have Plastic compressor wheel (front of the turbo) and ceramic exhaust wheel (back of the turbo)

R33 series 1 has steel compressor wheel and ceramic exhaust wheel)

R33 series 1 and 2 have exactly the same size housings/wheels.

R34 GTT has a LARGER exhaust housing and exhaust wheel

Rebuild of a blown R33 gtst turbo (series 1 or 2) will start around $1000 for a non ball bearing, steel wheels on both ends, hiflow and go up to just over $2K for the same job using Ball bearing cartridge.

so how much boost can ur high-flow take? turbo dave.....

do u no its limit?

and are restricted to 15psi?

or is becoz of ur e-mange u can boost higher than a 1bar???

i tht u would get a bit more power than that outa a high-flow..

sorry turbo dave

ive only FMIC, CAT-BACK HKS dragger, spiltfires with re-gapped ngk plugs to 0.8, apexi neo afc, bleed valve

and i make 190rwkw...at 13psi

mayb u need standalone mangement....

im after power fc, after fuel pump, and z32 afm...

but im hoping to pull bigger numbers than that, wit a high-flow....

:(

Mine is an auto so they drag about 25-30rwkw I have been told, so if it was manual it would be around 250-260rwkw which is as far as want to go with a stock engine.

If you are wanting more from a stock engine then I think the longevity of your engine and turbo will suffer.

I was also told by the guy who HiFlowed my turbo that 15psi is the sweet spot for that turbo.

Hope you get what you are aiming for from your HiFlow but the kw number isnt of much importance to me, as long as it drives good and Im happy with the power then thats all I want.

No offence but the 190rwkw you have wouldnt feel anything like a 235rwkw Hiflow.

Also the midrange pull from my car now is unreal, my stock turbo wasnt even close to being in the same race.

I am no expert but these are my opinions from what I have experienced and read about so far.

i recon wit a power fc and z32 afm, and a new fuel pump, i will be pushin close to those numbers...

my mid-range is crap now..lol

but dont forget im still on the stock computer, wit just a piggy-back...

so thats my main problem...

but wit a pfc, that should be solved...

and i recon ur e-mange fix'd ur mid-range issue too...

but how does ur e-mange handle wit the high-flow?

why not go wit standalone???

and im unsure about how much an auto/manual rb25det engine can take?

i tht it would b around the 300rwkw mark? but thats me..

dont forget every turbo and engine is different..

so yeah,

oh, by the way dave..urs is a series 2 rit?

Yeah Series2, 300rwkw is way more than I have seen a hiflow pull from what I have read on here in the rb25 results thread, safely anyway.

The stock exhaust housing runs out before then I think so thats when the VG30 rear housing comes into it along with a little more lagg.

But yeah, I was told 260rwkw limit on the stock engine if I want it to last so thats about 235rwkw with an auto like I said before.

From my understanding the Emanage Ultimate is very adjustable and doesnt hinder power output due to being a piggyback, I went for the Piggyback as they are more compatible when running an electronic auto.

Look through any of the major threads relating to ECU's and new engine management systems... IT should show you that the end result between the EMU and PFC are pretty much the same... It just depends on what your tuner is good at tuning etc...

Both are great units... and will net the same result in the end for you provided you have a competent tuner.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By GTSBoy · Posted

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      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!

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      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...
