great thread nice seeing a 1j in a 350z, needs something like this ideally the VG is a nice engine, ive just purchased my own 350z and immediately realised its begging for a whopping great turbo strapped to the side of it but trying to stay NA at the minute.
Id definately look into mounting the z33 box to the jz though none of the Toyota boxes are amazing, ive just mounted one of the boxes to my sr20 with a plate ive developed over the past year, it far exceeds the stock sr20 box and the ratios work very well with my 2.2 hks engine.
Nice to see the use of bulkhead fittings so on also, the electrics side of thing impressed me most though whats your background the canbus systems are a nightmare to play with but if im right toyota use a simular system on the altezza and soarer, o and great choice on the ecu i run a link G4 storm on my comp drift car, advanced ignition control, in built boost control (depending on what your running) sequencial injector firing and a range of input, and output controls great ecu, and so easy to use.
will keep an eye on this
