bobby, is john going to make a support for the turbo/manifold?

is he expecting any problems form the manifold warping?

Hi,

No need to support the manifold at all.

Well once the manifold is on the car and running i doubt if we have any problems his engineered it well enough to keep away from any problems.

The head is at Wilkins engineering to drill the holes. This will help remove air locks above the combustion chamber in the head. Once its done i will port some pics of the work.

I have done some wiring on the car, i have installed pressure and temp sensors before and after cooler using 4 core tefzel wire.

Hey Bobby, are you going to come to SAU Nationals and bring along that Z-Tune of yours? Im sure everyone would love to see it there.

Hey Ian, Sorry just have to much work on atm. You are more then welcome to see John on the way back as we are 5 min off the freeway.

So who is doing the head porting and assembly Bobby?

Cleaning of the ports have been already done, no porting required, and i have posted pics of ports. This was done by John Skola.

Motor assembly will be done by Trevor ( Johns Close friend) . I sent the head to Wilkin's engineering to drill the head to relief airlocks, and he also linished the throttle body shafts. Ill be picking it up tomorrow so ill post some new pics.

Graeme Wilkins and John Skola worked together many years ago on race cars. This is why John gave me the green light for Graeme to do some work for me as John does not know many people that are capable of doing the job correctly. Graeme is based in Seven hill on Stanton rd www.wilkinsengineering.com.au.

The head needed the holes drilled to relief air locks above the combustion chamber, the holes drilled are 3.5mm using a Mill and making sure you dont go drilling into the port or the headbolt holes.

While the head was there, Graeme has noted down many measurements of the work that John has carried out on the head. ie port shape port cleaning and final port size. So if you wanted your RB26 head ported in the same manner as mine (as i now john dont have the time to do it) you can always go and see Graeme to get the job done.

Also Graeme has milled the throttle body shafts, gave him one that John did and he copied them to all three. This will help increase the area in the throttle when opened fully for increased air flow.

Did you get the head on a flow bench?

+1 to Wilkins doing great work on heads

Yes the head has been flowed and sorry i dont have the figures as john has the file somewhere, once i find the file i will list it with the rest fo the calculations he has done. File is worth a mint !!!!!!!!!!!!!!!!: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.
