text: This motor was produced for use in the Skylines, Patrols and rights bought by Holden because the Holden 202 (3.3 L) powering the Holden Commodore could no longer satisfy tightening emissions requirements, and with all new cars required to run on unleaded petrol by 1986 a quick replacement was needed. Nissan Motor Co. sold the RB30E to Holden for the VL Commodore. Holden would give the engine the name 'Powertech 6Ei' and 'Powertech 6EiT' (for turbocharged applications), although these names would only appear in official videos and brochures, seldom being used outside of Holden content. The radiator being a cross flow design and is fitted lower in relation to the engine in the VL, there is an increased likelihood of air locks forming in the (alloy) cylinder head if the correct bleeding procedure isn't followed, causing this to overheat and warp. This was very unlikely in comparison to the R31 Skyline as the radiator is mounted higher. The engine proved to be very reliable apart from this issue. The RB30S was found in some Middle Eastern R31 Skylines and some GQ Nissan Patrols. The RB30E was found in R31 Skylines and VL Commodores in Australia as well as in South African R31 Skylines (with  at 5,000 rpm and  at 3,500 rpm)
