normally carry some changeovers in stock, but just waiting on new batch, should be here any day. Can also modify your actual ecu if preferred but takes a few days as I don''t have the smd work station yet. Normally looking around 2-3 hours drive in drive out for thorough tune with basic mods, obviously cam timing etc can take longer...

Sorry to bring up and old thread, but I was wondering if you are putting a z32 ecu into an rb25 and u get the 16 bit version you need a daughterboard that I know and then would u need two chips in order to run the tune? Cause thats what I have to do caus eI got the z32 ecu that is 16 bit so they told me I need two chips in oder to run it.

You should be able to use a 16 bit Z32 daughterboard to run an RB25 still since the ECU pinouts are the same, Nissan upgraded to a different processor (probably because of the Motorola/Hitachi lawsuit stopped them using the HD6303 MCU midway through production of Z32)

I would lean towards the 8 bit Z32 because more VVT control parameters have been defined if you wish to tune those. However I went through the 16 bit Z32 ROM last month and identified some more parameters to adjust since a few owners run nistune with these

hey im in the middle of doing the rb20 ecu with a rb25 tune chip on a rb25 but ive connected the computer and the car runs fine but no tacho just wondering if you need to change the tacho wiring on the ecu from pin 7 to pin 5 to suit the rb20 ecu

Maybe not that cheap @ approx $2000. :laugh:

should be half that, as of late have been doing the Z32 remps for $800 drive in drive out if you supply the z32 ecu ( or $950 if i supply it, as they are $150 at any wreckers)

there quite a bit of mis-information about exactly what needs dong but it is actually very simple and only requires simple pin swaps and the addition of a 02 sensor wire.

IIRC I was thinking that that the 2K would include wideband etc etc.

Sure only requires a few pin swaps easy as.

EXCEPT the fuel temp sensor which needs a resistor wired to chassis ground. If this isn't done you get rich idle afr's and code 42.

Oh and cut wire at pin 33 or your exhaust temp light will come on with your air con.

Cheers.

Guys I'm a little lost here , are you saying that a modded R33 GTS25T computer can be made programmable and tuned via the Consult port just like any after market computer ?

I was under the impression that ROM chips had to be burnt and erased and reburnt time after time .

If all is now good is the software available for anyone to use ?

Cheers A .

Sure there are daughterboards out there that allow you to use nistune boards in the r33 ecu it's just that they're a liitle exy.

      "Cheap" bolt on turbo on RB25DET NEO

      The fab work can be as simple as a couple of silicon hoses and clamps to the factory piping.

      Just sounds like either way you need to do some fab work to get everything to fit, so why limit yourself at that point? If the GCG high flow option is zero effort in and out swap though I'd probably do that. It's almost certainly lowest risk, lowest cost, etc. The HKS GTIII-RS option that Kapr mentioned is laughably expensive for what it is, they charge the exact same for two turbos on the RB26 so their margins are off the charts on that thing.

      Intake manifold is not a part of the issue. The turbo bolts to the exhaust manifold. That is easy. But close your eyes and picture the physical situation. That is a T3 flange on the manifold and a T3 flange on the turbo. As long as any new turbo has a T3 flange on the exhaust housing, that exhaust housing will bolt to the exhaust manifold. This places the exhaust housing in the same place as the stock one. But now move your mental attention a little further forward. The location of the compressor housing is set by the length of the turbo's core. The stock turbo had a long core. Let's say that it is..... 100mm long. So that would place the compressor housing 100mm forward of the exhaust housing. But a highflow, might well have a centre core that is shorter. Let's say that it is only 70mm long. Now the compressor housing will be 30mm further back in the engine bay than the stock one. This DOES move the turbo's compressor outlet backwards. It also moves the compressor's inlet backwards. You will very likely have to do some work to both the inlet and outlet piping to make everything connect again. I am not say this to make it out to be a bigger deal than it is. I am just pointing out that "bolt on" is sometimes not quite bolt on. The highflow from GCG that Murray linked above (https://gcg.com.au/turbo-charger-upgrade-skyline-gtst-2iu-xtrgts-s1.html ) uses a core that is the same length as the stock core, and so does not require this extra work. It will look very much like the stock turbo. No-one uses GTR turbos of any flavour (stock, or aftermarket) in a single turbo application on RB20/25. It's not a thing. Yes, people have been putting on GT3076, GTX3076 (and bigger and smaller versions of those) and G30s (of various sizes) onto RB20/25 since forever. But these are not "bolt on". Everything except the 4 bolts to the exhaust manifold change with these. And genuine Garretts are expensive. Non-gen, like Pulsar, etc, are cheaper, variously as good or nearly as good. But still not bolt on. No-one in the right mind would pay for an HKS turbo. Not in this modern day and age. Well, yes, the GCG highflow. You could ask HG what he can do to make the compressor housing sit in the original location. There are surely others doing highflows around the world. And some of the eBay/Temu ones (as reported by Dose) work and don't die. Bit of a lottery though. I would send your turbo to GCG (here in Oz) to be highflowed if you want a trivial no-extra-work option. But seriously, the work required to change inlet and outlet piping is not that hard. That's a boost control problem, not a turbo problem.

      Thank you all for the replys 🙂 I know that intake would be different but that is one pipe at it is not that hard to get(custom one). I meant mainly bolt to the stock manifold and the turbo elbow. I looked and many sites/forums but they are just "old" with some old HKS turbos from GT-R i guess? What about some Garrets?  Or any other turbo? Is there even a turbo which i can just bolt on? 😄 And yeah i know about that new HKS but that is like 2000k USD without taxes/shipping in here   Iam getting a touch up tune but my "problem" is that on the "not" hot day iam getting peaks around 0,9 bar...and when it was around 15 Celsious i saw peak around 1 bar which is just too much for stock turbo. And of course turbo is old and i like to get some new one for a piece of mind 🙂

      I'm working on the assumption that our friend Jasmine here is a Russian (or, possibly Ukrainian) spammer/spambot, based purely on the number of such that I have been having to neuter in the last few weeks. IP address for the OP above was in WA. But that could have been via VPN. Posting at quarter to 4 in the morning is a good sign of being from somewhere in Europe. The last Jasmine that I kicked in the cooch was IP addressed in Ukraine. Even that could have been via VPN, and the bitchbot could have been from Russia, Serbia, China or anywhere. Regardless, was a spambot, so I killed it with fire. The fact that our new friend Jasmine here did not respond in any way to my tart query strongly suggests to me that this OP was just the establishment phase of a user able to be activated for spamming in a week, or 3 or 10.
