Ryan!

Checked over everything ! no boost leak how ever i got a message from a fellow sau member and i think he's right, the turbo boost sensor is not connected/ i don't have one D:

Hey Everyone I have just put a standard RB25DET NEO into a R32 Gtst. Engine was out of an Auto r34 GTT rb25det neo) Ecu and loom is from a manual Stagea (rb25det neo) It ran perfect after i connected everything, took it for a spin and went great through all of the gears ! running 10psi now on my way back from testing i went to give it to it a bit and all it did was bog/misfire under load, so i thought maybe coilpacks/ spark plugs/ afm etc, Okay so i changed all that, bought new platinum spark plugs new conditioned afm, and another set of coilpacks, went for another drive, and again went good, THEN on the way back same thing its like as if the ecu reads something wrong and it goes into limp/safety mode??? also like to mention runs really rich too. OKAY now i have worked out when i disconnect the afm and put it back in its like as if it resets everything and when i go for a drive i get about 10 seconds of running good then it goes back to bogging/ misfiring under load. Is there something im missing that needs to be connected to the ecu ? what is causing this to happen? Also I dont have a diagnosis plug haha and wanted to also ask if i buy a power FC with hand held and connect that to a computer will that tell me what is wrong, and a friend of mine told me a power fc ecu does not have limp/safety mode so will run normal with one, is this true? Thanks kindly !!

Hmmm okay looks like ill get a nistune after i get it started and see how that goes. but yeah im wanting to cut the plugs off the R32 gtst loom and use them on the NEO loom, if you do find any information on how to do it please lemme know. and Josh, did you find any photos ???? thanks

Hey so where is the actual walk-through ?? haha

Sweet, ill send him a PM But if you can get some more information/ photos that will be good! and i will search on the how to guide as well ! thanks

Hey guys So basically i have put a RB25DET NEO into a R32 GTST Everything mechanical is done. I have used the RB25det NEO Loom and ECU I basically need a guide/help on wiring the Rb25det Neo engine loom to the R32 gtst body loom and to basically get this thing started and running. Now i have searched everywhere for days found little bits and pieces like this : The internal wiring is the only hard part. You need to place the wires from the 34 loom into the factory 32 internal loom. This is easy if you know what every wire from the 32 and 34 ecu’s is and what thus each wire in each plug in the 32 and 34 kick panel is. It is easiest (in my opinion) to cut the internal loom plugs off the 34 loom and off the 32 loom where it went onto the main ecu loom, and attach the 32 plugs onto the 34 ecu loom. This way, if you crash your 32 or whatever and want to put the neo into a new 32 all your wiring is done basically. If you do it the other way, you will also need all the corresponding 34 internal plugs from the internal loom. I say do it the first way. It’s your choice. The only point to really note and emphasise here is this: The r32 is basic. The 34 had TCS and ABS. Each system in the 34 has it’s own computer ie for the 1. Engine 2. TCS 3. ABS Each computer works both independently, receiving the signals it needs to and consequently processing them, and together. They all talk to each other. If you remove the ABS computer (or in the 32’s case, it was never there to start with) the engine computer does not see a signal from the ABS computer, so it thinks the car has no brakes. And it won’t go. So you need to trick the ECU into thinking that the TCS and ABS computers are their, functioning properly, and sending a signal so the ecu thinks you have never locked up braking or lost traction whilst driving. The information on how to do this, along with spreadsheets of what every wire in the 32 and 34 kick panels is, the plug layouts, ecu pinouts etc is all available via application in writing Now it says what to do but not how TO DO IT ?!?! does anyone have a guide or write up for this? OR know how to do it Thanks kindly Ryan

Hey guys sorry to bring this up but i have just put a RB25det NEO into my R32 gtst, everything mechanical is done, now I'm up to the wiring, i am using the NEO loom and ecu, basically the body wiring of the 32gtst into the NEO loom is what im wanting to do. does anyone have a write up or guide for this ?
