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.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
