just spewing coz its got absolutely NO midrange

the hks2530 is known for its midrange torque so there definately must be something causing your turbos not to start pulling and spinning the wheels as soon as you stab on the throttle.

sorry hud let me clarifiy you need to keep the restrictor as it reduces the size of the hole the air has to travel through which increase the pressure holding the wastegate(act) closed ( think about a garden hose when u put your thumb over the end) Ive read that by altering the size of the hole in the restrictor you can change how the turbo ramps up on boost ie make it spool slightly earlier or later( hpi mag did a build up on a jap spec s15 which they did this on) if your missing the restrictor entirely by using pretty blue hosing instead you may get the problem you have as there is not enough pressure holding the wastegate(act) closed

damn so 1 bar @ 4,000rpm is resonsble..? i was looking at the hks line of turbos for my r32 (rb20) was thinking

- GT2835 pro S

- GT-RS

- GT2530 (KAI what the diff with KAI or not??)

was told GT-RS would be laggy get the 2835 pro and i guess there going to shit aswell so might be looking at 2530 now?? anyone have any ideas on what the other 2 would be like??

I remember reading in some post that the new 2530kai is rated higher than the old 2530 in terms of power...old 2530 was 320ps i think and the 2530kai is something like 350-360ps or something like that...try searching here...

    • 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.
