R33 Hypergear Highflow - What Boost To Run?

Ok, before peoples panties get twisted into oblivion, hear me out. The Hypergear turbo thread currently has 10953 REPLIES and 548 pages and so its a bit much to ask for me to read through them all to find my answer. It would take weeks.

Here it goes.

I have a Rb25det R33 with FMIC, oil cooler, full exhaust and a new highflow Hypergear turbo. I'm later planning to get fuel pump, Z32 AFM and nistune upgrades, but until then I'll be driving it around as is. Im currently on standard boost as Im not sure what's safe to run (and yes, for best results I should take it to a dyno, I know).

My very simple questions for those who have trodden the same path is, what boost can I run this combo of parts SAFELY before I run out of air and or fuel and damage my engine?

Help from those who have done this is much appreciated.

Thanks

you need injectors and afm, nistune are great (we are one of their biggest customers) but not on r33, go powerfc. We pull 2 or 3 nistunes out of r33 a month that have been tuned elsewhere that just dont perform right. The dont work properley as you have to retro fit another ecu from R32 or Z32 into the r33, there are certain background trims that can play havoc that are not adjustable.

Nistune is the worst thing you could do. I've run out of fingers to count the number of 33's in the pits not working because of 'something' wrong with the car running nistune.

I's get a pfc asap and get it tuned. It's not if, but when the engine will let go when it's underload and on boost.

I know someone that's running one on 12psi and pulling hard too, no problems but don't know how long that will last, yes I know pretty silly and ive told them too, it has a mines ecu which is probably running very rich, its a rocket though!!

So Status, Power FC would be the best for an R33? As its a street car keeping everything working smoothly for day to day use would be my priority, with a good, safe tune being a very close second.

I knew that R33s required a different approach with nistune, but if its going to be an unreliable solution, then sure, best to avoid.

The turbo has the OEM wastegate still on it and I recon, with what people are saying, I'm going to keep it at stock boost. Damn, my shopping list for parts is growing tho.

Ahh, cars....

nistune is fine if you use a Z32 or R32 ecu and is probably cheaper than a PFC if you're looking 2nd hand

beware with the R32 ECU you will need an external switch for VCT as the R32 RB20det and RB25de didn't have VCT

I'm pretty sure the nistune update has allowed vct to be controlled by either the led light output or air con output with a 32 ecu.

Emailed Stao after getting and fitting the turbo and never got a reply. I also think its best to get some real world information before approaching a tuner, hence asking for all your opinions.

And on that, do we think that Power FC is the best/ a good approach for tuning an R33 to be a reliable street car (with all the various needs and functions of a street car; cold start etc etc) or are there other popular brands/models to consider?

I dont think i have received your email.

I can supply adaptronic plug in at a special price if interested. If u r in Melbourne goto see chequred tuning.

Make sure u have fuel mods, 3 inches metal induction pipe, pod, good fmic, 3inches free flow tubo back exhaust and a good clutch before going for tuning.

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

      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!

      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...
