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.

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
