I am still ongoing with my build and am still going at this Hypertune V2 manifold plumbing. This manifold replaces the entire coolant block that normally bolts to the head and routes the hot coolant to the radiator. Instead of this cast piece, you get (4) lower AN fitting ports and (3) upper air bleed AN ports.

The lower ports are:

(3) -10 AN fitting (starting from rear coming forward)

(1) -6 AN fitting (at the front of the manifold near the water inlet neck)

The upper ports are:

(3) -4 AN fittings (which I'm pretty sure I'll be replacing with standard barbs).

I am having FITS trying to locate a position for all of these hoses to go while making room for fuel lines and dodging my oil cooler plumbing. Also keep in mind I'm trying to ensure that this unit is serviceable (IE-can still remove the manifold without pulling engine). It's been a trying task to say the least, but I think I have a workable solution.

I have attached a design that I'm going to build this weekend. I still plan on using the stock ECU coolant temp and Gauge coolant temp sensors and they will be contained in this manifold as well.

So the things this manifold will collect:

(3) -10 AN lines from hypertune manifold

(1) -6 AN line from hypertune manifold

(1) ECU coolant temp sensor

(1) Gauge coolant temp sensor

Turbocharger water return line

Main outlet to radiator

I'm using a piece of aluminum stock that is 1.290" OD x 1.050" ID

The fittings are -10 AN weld fittings from Summit racing and -6 AN weld fittings from them as well

The Tapped bungs will be just cut to diameter, drilled, tapped, and welded on.

The (3) -4 AN fittings for the vent will all be collected to a small swirl pot which will be located near the firewall (brake booster) area and the lower end of this swirl pot returned to the coolant inlet into the block (will get pictures of that later).

I plan to support the rear of it from the strut brace since the engine may vibrate more than the radiator + strut brace.

Tell me if you think I'm missing something before I start the fabrication?! Forgive the mocked up rusty steel pipe, it fit well into the stock radiator and helped visualize / measure.

Thanks,

Patrick

Well this is what I have. Not the prettiest as we did it on the MIG machine, but it looks like it should work fine. The -10 AN hoses wrap around the intake manifold and collect into this header. I also zip-tied the swirl pot in the rear. I'll be running the 3x small fittings from the top of the V2 manifold (vapor bleeds) to the swirl pot, as well as running the radiator overflow (with no pressure cap on it) to the swirl pot which will then be run to the back of the water pump (constant bleeding during circulation).

Big hurdle here. This should be offered with the Hypertune V2 manifold.

Not a bad setup. Im actually having the same issue with my hypertune manifold. What if i was to put the coolant sensor on the radiator breather? Just not sure if it would give correct reading.

    • Um. No. Since Matt introduced the TIM it has become a lot easier to deal with the consequences of changing K for AFM and injector swaps. Then, tuning is a f**king doddle. No-one needs to know or care how many grams of air are flowing or any other bullshit. Need more fuel in a cell? Add more fuel. Need more timing in a cell. Add more timing. Need to adjust any of the other tables for warm up and so on? No harder than anything else. Sure - it's not an ECU system for starting from scratch on an arbitrary engine. But then.....it was never supposed to be, not recommended for, and almost never used that way. So.... On your engine, in particular, Nistune/Nissan OEM is about as sophisticated and difficult as banging 2 rocks together. Those ECUs are primitive and simple. There is nothing difficult there. I learnt Nistune from scratch, created new maps with extended axes, interpolated/extrapolated the original maps onto them and tuned my RB20 (basically the same ECU as your 26 ECU) all by myself, more than 20 years ago. And that was long before even TIM.
    • Set of knee pads for a R34. Will fit every model I think. Comes with everything except the rubber covers for the bolt holes. Still in great condition. You will need to drill holes to mount these or use double sided tape. I can do free shipping and will be shipping from the Netherlands with tracking.
    • Nistune needs something like an entire excel spreadsheet in which you build an abstraction layer that converts everything from real units you can actually measure into all of the various tables. The number of unexpected dependencies hiding in how the Nissan ECUs do math is a pretty impressive optimization trick for 8-bit MCUs but good god is it awful to actually work with in practice.
