Hey SAU.

Before you flame me you might like to know that I have spent an entire day searching google, and I even went through every single DIY on this forum and found nada.

For a R33 GTR

All I would like to know is, can I buy a aftermarket boost gauge and use the stock hardware and then mount it in the stock position?

If this is possible what gauge would I need to utilize? i.e defi, blitz and is the gauge 52mm?

Thank you all

I don't see why not...

Many ppl have replaced the stock Boost Gauge with an aftermarket one in the stock position.

I assume it is just a matter of removing the stock one out and connecting up the aftermarket one and putting it back in.

Just measure the diametre of the stock gauge and find an aftermarket one with the same / similar measurements.

I have an aftermarket boost gauge, but is mounted behind the steering wheel.

And all there is, is just an air hose (to read boost pressure) and a electronic wire to tap in to the wiring / light electronics so when I switch on my lights, the boost gauge lights up aswell.

You would be able to mount it in the stock position for sure, but I don't know about using the stock wiring and sensor if that's what you're asking? I doubt the stock wiring harness will plug into any aftermarket gauges, and the stock sensor is notoriously inaccurate. Wiring is very easy anyway, why use 15 year old wiring and sensors when you can get brand new stuff with the gauge you buy? Takes an hour to install neatly.

    • Oh, also, forgot to add these photos I believe.
    • Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !
    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
