Ok as title suggested, my r33gtst is starting to morph, into a dedicated track car, but I would like to drive it on the street every now and then, as I already have another street car.

The problem is,I'm looking at cusco diff, and which one would suit me better

The 1 or 1.5 or 2 way?

Track car? ideally you want a 1 way diff but if you have to 1.5 could do it. Leave the 2 way diffs to the drift wannabes.

skylines like most modern cars understeer into corners and the last thing you want is your rear wheels locked together encouraging the understeer and stopping turn in.

I used to have a tight 1 way in my 33 gtst and it was brilliant on the track :D

Oh, and if it is track only get it *really* tight, no such thing as too tight unless it is 1.5 or 2 way ;)

    • See my post here If you put the Haltech in, you won't have to worry about any of that. And, in case you're worrying about my lack of credentials in doing your exact swap, I put a Neo in an R32. There has never been a stock boost solenoid near my car and the Neo's ECU has never cared. Nor should it, because it is electronically impossible for it to care.
    • That's 100% wrong. Did you wire in the boost sensor? If you did not, then that is 101% your answer. Neo ECUs do suck a bit.
    • Hello, I'm trying to make this thread basically the thread with all the answers to common questions regarding specifically the RB20 DE NEO + T engine, that comes in the R34. Answers will and only should be provided by those who have done this conversion or actually have some relevant real life experience please. Please feel free to ask questions in the comments if you have any so other members can answer. I feel like this thread is really needed, especially with more Americans buying (unknowingly going to regret it too) rb20 neo r34s. My first question being - What do you guys use for tuning? I have purchased a haltech elite 2500 Plug and play kit for the rb25det NEO because the ecu plug is the same, but I am unsure if any of the pins would need to be repined to match. Second question that I see asked very often - After this conversion, did you install the boost solenoid/ actuator? I see many people doing a + T setup on their rb20 NEOs while running stock RB25DET NEO ECUs with no tune. I am wondering how they are going about doing that and consistently abusing the car because many of these people have had these untuned setups running for a very long time. That was my original plan, but my engine cuts out at 5 psi of boost using the stock ecu with no tune and no boost solenoid/actuator.
    • interesting. ive read and heard otherwise over the past year. ive been doing this +t conversion on a rb20 neo using all oem rb25det neo parts including the ECU, and im having engine cut out issues when I hit around 5 psi of boost. Everywhere/everyone ive asked has told me its because I never wired in a boost solenoid/actuator to the ecu, so the ecu isn't getting the right signal once it hits 5 psi of boost, causing the engine to get shut off.
