Currently an owner of two 1JZ-GTE both with single turbo. One 1JZ-GTE swapped in Rx-7 with R154 gear and exedy twin plate. Turbo Holset HX-40 almost equivalent to GT40R. 650CC injectors, HKS Fuel Cut Defender, Piggybacked with Apexi Vafc 2, Apexi AVCR boost Controller, running 1.8Bar on stock internals. Please don't ask for dyno reports as we don't have any dyno here in Pakistan :(. Another is Nissan Cedric old car currently going through swap with 1JZ-GTE W58 gear. Turbo Holset HX-35. 550CC injectors, HKS Fuel Cut Defender, Piggybacked with Apexi Safc 1, Turbo smart manual boost controller, will also run 1.8Bar on stock internal. And yes 1JZ-GTE can support 1.8Bar on stock internal. For drag races also tested 2.2Bar on stock internal. Then back to 1.8Bar, and engine is still safe and sound.

Here is the video of my RX-7 with an AFR of 10 something. Running 1.2Bar boost. Had to hit rev limits because of traction issues. I was using normal street tyres.
