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:

    • Well you could certainly buy or build an enclosure for a pod in that corner of the bay. It is absolutely vital that there is a nice big opening to let cold air in to it from the front or underside, otherwise it will just pull air in around the edges from the bay, and if that air is hot, you gain nothing from enclosing the pod. There is lots of good evidence around (including on here, see posts by @Kinkstaah for example) showing that pods pulling hot air from the bay is only a problem when you're static or slow in traffic, and that as soon as you get the car up and moving the air being grabbed by the pod cools down. Although that will obviously vary from car to car, whether there is a flow of cold air to the pod or if it all has to come through the radiator area, etc etc. Obviously, the whole exercise requires as much thought as anything else does. Doing the lazy thing will often end up being the dumb thing. The stock GTT airbox has a cold air snorkel to feed it from over the radiator. Shows that Nissan were thinking. The GT airbox is upside down compared to the turbo one, yeah? Inlet at the bottom, AFM/exit on the lid? That might make it harder to route the turbo inlet pipe using the GT airbox than a turbo one. That would probably be the main reason I'd consider not using it, not that it is too small and restrictive. I'm looking at a photo of one now and the inlet opening seems nice and large. Also seems to have the same type of snorkel that the turbo one has. Maybe all that's required is to make a less restrictive snorkel/cold air inlet, perhaps by punching down through the guard like I did.
    • Also seen this as an option 
    • I get you, we’ll see I’m aiming for 200ish kw now and hopefully 300rwkw down the line after some upgrades maybe like headstuds, E85 flex fuel etc  so trying to make it final for that now, I can get a GTT airbox for $280 so it’s not too bad but not sure if there’s better ways to spend that money. I seen online they say pod filter which isn’t enclosed isn’t good especially for a plus T.      hard to say what to do
    • Meh. How much power can you make from a +T anyway? I wouldn't have though it would be enough to challenge the airbox. It's not as if it's tiny compared with the turbo one. As to putting a pod in a stock airbox .... it's not the filter element that would be restrictive. It would be the air inlet to the box that would be the narrow point, which you could open up regardless of what element was inside. On my R32 I opened up the sort of triangular opening in the bottom front corner of the box, deformed (heated, moulded) some 4" stormwater pipe to fit to that opening and punched a 4" hole down through the inner guard to the spot where the stock intercooler used to be. This was purely in the search for a cold intake, but you could do something similar if you need to open up the inlet side of it. The AFM tube size is the same for both NA and turbo, so the outlet from the airbox is same same anyway. If you're going to do the right thing, then an aftermarket ECU won't care about the AFM (ie, you can get rid of it). But even if it was still there, people pull >300rwkW through them all day, and I suspect you won't be going there.
