ADM,

Are you the bloke that Andrew is doing a price up on?

The RB25 head has hydraulic followers so from what I've been told everything is fine with the 2 oil feeds. Only time you are required to block on off is with the GTR head which is solid.

The SOHC has a few draw backs.

1. Fuel efficiency.

2. Lack of rev's.

3. It does make less power for the same setup of boost etc.

4. requires less static comp ratio as the sohc head is more common to detonation

5. requires more boost to be run to make the same power.

6. they seem to bit a little more peaky with narrower power band (lack of rev's)

+ to go the SOHC head I would have to change ecu etc as it isn't a straight bolt in.

I guess its like saying why go a RB30DET when a worked 5.7ltr will make the same power. :)

Im BAAACCCKK!!

PC shat it, so i let dialup expire, but im back now with BROADBAND!!!

Details of car to come with list of items for sale.

engine just needs manifolds bolted on, twin plate, and rb25 gearbox then vrmmmm - down to see Shaun at Boost Worx :P

    • 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.
