Man if its only temporary, i'd suggest an APEXI SAFC.....Yes yes i know they are old tech but they work very well for stock/mild cars and are mega cheap these days. $100 for an SAFC and $150 to tune it you could run your highflow and even up the boost a tad, then when you get some extra cash you can always get your money back for the SAFC. Just a thought.

This could be read as it is safe to run 22psi on the stock ecu with a highflow, which is very wrong.

Please fix your post so we keep everything accurate.

What is the correct maximum amount of boost you have safely run on a stock ECU with a highflow?

yep thats how i read it

how would the car perform with the highflow turbo and no tune?

I will post a photo of my turbo for more understanding haha

why highlow, just get rebuilt turbo....with wheels that dont self destruct

Old turbo died and took out motor... coin spent on new motor, ideally wants more power, but doesnt want to spend more money... hmmmmmmm

I would rather spend $900 on a cheap nistune + tune than getting a different turbo for "reliability".

This sounds like good advice.

no nistune option is cheap for an r33....if you dont know this already you do now, so you can stop giving crappy advice :P

SAFC can only bend the AFRs, however it does not change timing.. if you look at the stock R33 map, timing values are around 22 on noise, which is heaps if you decent to add in more boost.

Like I said, best option is a Toshi remap.. happy days pump nearly 1 bar into motor no knock, and happy AFRs

oh ok. thought it'd just be like a daughter board or something... pulsar ftw

The SAFC doesn't bend AFR's, it bends the Airflow meter signal, which in turn causes the ECU to reference different cells(Fuel AND Timing) than it would without the AFC.....plus i only recommended it as a cheap alternative till he sorts out a proper ECU ;)

Yeah I know what you mean, I just said AFR because bending the AFM signals causes the AFRs to change.

However you do realise that will cause the ECU to reference cells with less load = more timing right?

Ofcourse, however in the last few 33's i've installed these into drive great and do not ping at 11-12PSI(11.5-ish AFR)

its all good! going R + R is good motivation to get the ECU upgraded.

I admit making an mistake quoting the maximum boost level safe to run on stock ecu earlier. Been corrected and that it should be no higher then 10psi.

Reason of having the high flow, as cost wise is similar or cheaper then to rebuild, similar drive ability working with factory ecu, making good power when other supporting mods are present, and proven by time to last.

For a budget ECU upgrade you can get Toshi to remap based on factory injectors and AFM. I've personally sent few customers that direction and worked well.

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By R34_GT to Turbo · Posted

      Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks

      R32 GTS (RB20DE) Injectors Replacement

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
