Ati Harmonic Damper Killing Oil Pump !?

My tuner had 2 gtr this year where the oil pump failed on the dyno.. he blame the ATI harmonic damper. both had it. one was a rr32 if I'm not mistaken but the other was a r34 with the good collar. He then warned me to go back to stock.

Is it the oem pump problem or is it known that the ATI might not be as good of a solution as people think?

Honestly, I blame both engine beeing 10yr old and pushed more than 500whp, maybe hitted limiter too many times, oem pump.

Asking the guru at Aus.

Plenty use ATI without a problem, plenty use OEM without a problem.

Old age, bad treatment and 10-20years of work (depends if its a 34 --> 32 motor), combine that with limiter slapping as well on a tune that is hard on timing on the limiter.

It's all a recipe for a failure of some kind be that oil pump or something else.

      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
