a 3076 will bolt up to a standard manifold, but you may need some oil fittings.

as for the ecu, any aftermarket ecu will do the trick. you are best of asking the person who is going to tune it what they prefer. by using what they know the best you will get the best tune from them. if u get something they aren't familiar with you won't get as good of a result.

and i think a 3076 might be a bit big for a rb20 unless you are chasing big power. it will partly depend on what housing size you get.

but i don't know that much about what turbo is suitable for rb20's.

It does fit on the standard manifold...but by about 2mm you are best off getting a spacer made up to give the compressor a bit more clearence, apart from that you may need new oil and water lines and the intake will need to be jigged slightly

actually the spacer you need is about an inch thick. i installed a 3076 on a mates 33. and you will need a new intake pipe as the compressor housing needs a 4" intake , and you need to make a few mods to the 'hot' cooler pipe.

a good bolt up replacement is a highflowed r33 turbo from gcg. they are a 100% factory fit, but as your turbo isn't standard some of the oil and water lines may have been altered, but a trip to a local hose place should sort you out.

ya an inch thick is what mine was too! i was saying it did 'fit' straight on to my manifold by 2mm but it was deemed more clearence would be wise ha ha

Im gonna be unoriginal and say that a GTRS or garret equivalent would be good on a RB20, cause the 3076 on my car felt a little laggy and that was with a 25

      R34 RB20DE NEO + T ONLY

      By Sxnjeet · Posted

      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.

      Something strange is happening. I didn't touch the car since we last spoke on the forums. Yesterday was the first day of good weather, so i took it out for about 2 hours. It started up on first crank every time about 5 times total. I literally didn't do anything to do the car.

      I purchased this one. Very well priced and works great. I was rough with it to see if it will last and had no issues.  Teslong Two-Way Articulating Borescope with Light, Industrial Endoscope Inspection Camera with Articulated Probe, Flexible Mechanic Fiber Optic Snake Scope Cam for Wall Automotive Engine Inspect-5FT : Amazon.ca: Industrial & Scientific
