I'm considering this turbo or rebuilding my hi-flow. How much shaft play ? I don't want to have to rebuild it after I put it in. 240kw seems low, and a bit worried would have to screw 20lbs into it to get the numbers. Want 250kws. Very hard finding a VG 30 housing for a good price for my R33.

skylinecouple - my engine is based on the rb20 and the fact it is low comp, means it requires more boost than a standard engine to make the required power.

shaft play isn't abnormal, it is minimal, the wheel spins freely and doesn't blow any smoke.

also because my engine is rb20 based (standard head as far as i know etc) it flows differently to rb25. The rb25 would be able to obtain the same reading on lower boost because of the compression difference. Another thing to take into account is that i could easily of made 280rwkw at a different dyno hence why i added dyno is renowned for reading lower than most.

krzysiu - thanks for the post :cool: good to give feedback on the potential of these. for how easy they fit and the performance they deliver its good to get feedback from others that have fitted them.

cheers

-Matt

    • 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.
