hi everyone

i have blown my sr and instead of replacing it im putting a neo rb25 in it and i have purchased the motor already but it came with no wiring loom i have a r33 rb25 loom spare and im wonedring if i can use that loom i know a couple of plugs mite be differant but i have downloaded the loom diagram for both motors and they are the exact same. i was hoping to do the wiring myself because i have done it a few times and have a fair idea on what to do.

for the intercooler setup i know that i cant run the intercooler pipe imbetween the radiator and the front of the motor so i was going to purchase the greddy inlet mani but i heard that ( i think ) its the traction control setup on throttle body causes a bit of grief doing that.

and i heard that the rb20 yoke for the gearbox is the exact same as the s14 sr box so i was going to run an rb20 box because i had an r32 drift car before that that had a 25 that was making 279 kw and it only had a 20 box in it and never missed a beat it copped a thrashing and was perfect so i would rather blow 3 of those boxes than 1 25 gearbox

just wondering on what u guys think would be my best option to go about these problems

thanx heaps

I've got the bottom end or a wiring harness for a RB25 neo that was in an automatic Nissan Laurel if that helps any. It was chopped just before the ECU, so it should have most of the plugs you need.

      R34 GTT idle problem

      By Dose Pipe Sutututu · Posted

      Oh yeah forgot to also mention need to also unplug the IACV as well. Thanks for the reminder @MBS206 Unplugging the TPS takes it out of closed loop so you're able to screw down the IACV without the ECU trying to add/subtract timing to maintain the idle (not sure PowerFC can even do this, but Nistune and the OEM definitely does)

      Nissan Skyline R34 GT-T 1999

      For sale is my 1999 Nissan Skyline R34 GT-T, tuned to 234 kW / 313 hp. I've had the car for a few years as my daily driver. The car is original (as far as Skylines go), with only a few minor upgrades to enhance performance and driving experience, as typical for such a car of its age. Overall, it is in great condition with no body rust, thanks to its earlier import date. It features a top-notch security system (not literally, but it's great!) with remote start and still functional 4-wheel steering via HICAS. It comes with several performance and handling upgrades, including:     Hypergear 450HP Turbocharger running 17 PSI boost, installed mid-2021 by Jaustech     550cc injectors     Nistune ECU     Front-Mount Return-Flow Intercooler     X-Force Stainless Steel Exhaust     Upgraded engine mounts     Bottom end bearings replaced     BC Coilovers     Lenso DR1 rims     Bridgestone Potenza Adrenalin RE003 TL 245/40R18 97W tires, fitted early 2023 The interior is mostly stock, with a few additions:     Viper Satellite Tracking System with remote start     Bluetooth Double-Din Touchscreen Head Unit     Steering wheel cover Cons:     A few paint imperfections here and there     Driver’s seat shows more wear than the others. It's not torn at all, but I've added a seat cover to protect its condition. I also have a CarVX Vehicle History report available for serious buyers, so you don’t need to purchase it yourself. Price: $26,000 ONO.

      Troubleshooting - motor wont turn over

      By TurboTapin · Posted

      I've had two suzukis in the past have an extremely hard time turning over and not starting after sitting for a few weeks. Ended up the alternator would seize up causing the starter to force. Same issue both times.  Maybe they're sourcing their alternators from the same place...

      R34 GTT idle problem

      On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
