I've got it in and it pulls hard up top but a couple of things have happenned.

Firstly it runs 15psi at low boost

and secondly,in first and sometimes second it hits what seems to be a fuel cut.

Is that what it is?

Whats my nexts step?

Do any of you with high flows or bigger turbos run that much boost as soon as its in or hit a boost or fuel cut?

I think I need aFuel cut defender and regulator for more boost.

I'm not that rich at the moment even though my fuel mixture is.

Heres the old jigger.

Hey Rick, how are things?

Did you get that off Kaos Racing?

Dude, I thought that Jeremy's Skyline was tuff enuff, but that turbo looks awesome!

:);) ;)

Yes he did, and yes it is :P

Jeremy is not content with 'only' 12 second passes... nuff said.

Well, I can understand that as 12 seconds is REALLY slow......:P

I suppose I will have to get a 3037 or a GT30 or something then....

Reckon that would be enough to keep up?

:shake:

Make sure you let us know how you go. Pop your dyno run on here for a looksie. You will probably at least need a Fuel Cut Defender to get the most out of the turbo. Besides having fuel run out maybe. I have a FCD they are quite fiddly the more boost you allow the more the fuel leans out. Good to a certain extent as our cars inherently run rich. Other people have used fuel bleed valves to lean out fuel.

I'll get a pic of the curve soon.I got 266hp at the wheels with next to no difference at 15,16 or 17 psi.It was still running rich but we didn't risk another psi.The curve flatened at about 240 hp then jumped up and flatened on 266.Not bad concidering I have done nothing but change the fuel pump.

    • 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.
