Turbo Replacement Without A Turbo

[Dose Pipe Sutututu]

Toshi sockets & installed a remapped rom into your ECU

and is about half the price of a Nistune.

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

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

yeah its a daughter board and a z32 ecu and a separate VCT switch and just a whole lotta assing about in general...

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.
