R33 Hypergear Highflow - What Boost To Run?

[ausdrift]

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

No boost is the safest option...

Run out of air?

[STATUS]

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 ran that turbo on the standard ecu until I had it tuned. It ran like shit on 10psi with an r32 actuator so I fitted the standard actuator and it was fine. Not great to drive though

[AngryRB]

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!!

Run the lowest as possible, install the OEM wastegate if you can - at least the car will be drivable and not hit TP Load cut aka R&R.

[ausdrift]

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.

[Blackkers]

awesome. and apparently they've added flex fuel to a few models too

[Dose Pipe Sutututu]

& launch, reading on the forum it's ignition cut too for the bang bang

still buggy.

Why ask a forum

You should be asking your Tuner/Stao

[ausdrift]

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?

many of us have been in this situation before

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.

[ausdrift]

ok thanks Stao, will keep in mind

[Dose Pipe Sutututu]

^ and I have a map you can use with your stock injectors, and a hypergear turbo which is good up to 1 bar (maxes out injectors) lol
