The engine is still a 3.0L, and I will get the compression ratio ASAP (I don't know off the top of my head what HG this has on it ). The bore/stroke should be: 86.0mm/71.5mm, the same as a stock 2JZ-GTE.
The head has had a 5-angle valve job with Toyota valve stem seals, Crower Stage 2 (272/272) cams, Crower titanium valve spring retainers, and Crower race springs.
If it matters for anything, the fuel system consists of dual Walbro fuel pumps and 850cc Siemens injectors.
The cams are 272/272, and have a duration of intake/exhaust: 229"/231".
I couldn't find a compressor map for you, but it is a 67mm DBB turbo.
