Long time reader, finally decided to make a account and ask something, now I have searched and searched but can't seem to find a definitive answer.

Which is the better turbo for response, I know they are similar but is a general preference in which one to run? Both are similar but is there a overall "better" turbo?

Have a look at the RB26 Dyno thread and it becomes quiet evident. The -7's are pretty outdated now (basically N1 equivelants), not to say there is anything wrong with them for a street car but if I had the choice between -7 and -9 I would go the -9's without any thought.

The -9's have virtually identical response with a higher top end. Only downside is that they dont come with actuators and are in turn slightly more expensive when coupled with a set of adjustable actuators (couple of hundred $$$ difference). Aside for that -9's all the way :thumbsup:

    • 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.
