RB25Neo/30

A bit stuck, done a search but just confusing the f**k out of me. 

Got an RB25Neo/30 in my R32. Using the rb20 loom, got a coil conversion loom and rewired the injectors. 

When it comes to the ECU, what can I actually run? From what I have worked out there is a GTRLink that I can use as it's the same ecu plug. 

Found a Vipec V88 for a neo, that won't plug in though will it? How do I get around this as it's a good price.

 

cheers.

Hi mate

you only have 2 sort of easy choices here.

1. Remove the loom, and install a RB25 NEO loom to run with the Neo Vipec.
2. Get a GTRLink / Vipec. These fit all GTR models, and the R32 and R33 GTS-T. 

Any other way will only be a huge bitch.

You could get yourself a brand new wiring specialties Neo harness. Would cost about $1k but then you have a new loom. 

Personally, since later model Neos have fairly new looms in then, just grab a factory one of those nice and cheap

When you say get a GTRLink/Vipec which Vipec is this that will work?

Vipec and Link are the same thing / same hardware. Vipec is actually gone now, absorbed back into Link. 

Vipec "V" series = Link G4
Vipec "i" series = Link G4+

You want the model of vipec or link that fits the GTR. It also fits the RB20. (It's a one ECU fits all)

The GTRLink / GTRVipec fits everything except for the Neo as that has a different plug.

Damn this one fits a neo, that's a no go.

 

Thanks heaps mate.

There is no RB25 Nistune so if you have an RB20 Nistune that will work although it will not control your VCT.

If you get a Neo ecu and loom you can get a GTT  LinkECU to put inside the Neo case which would be ideal...it can control your VCT and with a solenoid better control boost.

I have the same dilemma with a rb20de cefiro. It's auto and I want to keep it auto. Can I use a link rb26rb20 plugin? Do they have a built-in map sensor to do away with afm?

I don't know where the auto ecu is on your cefiro. If it is in the main engine ecu then no you will not be able to use the GTR Link. Why don't you get a wire in Link instead and yes you can use a map sensor with it.

Do you know how to find out? Will it be in the same location behind kick panel where main ecu is? 

I have an rb25 det manual loom and ECU, should I fit that and get a manual valve body for the auto to do away with the auto electrics? Then I could fit a plugin ECU .

I'm running a 2530 neo in my r32 gts4, basically had to do a small amount of soldering for tps and idle valve and coil harness. Add in a wire for vct
Can use pretty much any plug in ecu for r33 r32 gtst or gtr. Some need an injector pin swaped around and if using GTr or 32 gtst ecu need a way to control vct, so rpm window switch or if using an r32 gtst nistune then use the feature pack and it let's you control it like stock
I use an adaptronic select on mine personally.

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      Ticking Sound On Idle - Rb25

      By GTSBoy · Posted

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?

      Sorry for reviving an old post, but I'm having the same hot idle tick issue. Did anyone ever find out what it was?  I have checked/ replaced Injectors Coils checked Lifter clerance (is at zero) Checked Cam lobes Replaced exhaust gasket and studs Would appreciate any advice this is driving me nuts

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
