I'm trying to keep to some sort of budget so was just trying to weigh up my options. Biggest problem will be the triggers for the ECU. (without making a custom chopper plate or putting a VQ25 flexplate behind the VQ30. If that's possible.)
I've managed to track down a Y34 wiring diagram that was in Japanese that I have converted to English - Im hoping l'll be able to get the Y33 ECU to run the engine without too many troubles. The idea of fly by wire Nissan have incorporated in the Y34 is horrible.
To answer your questions -
We have mocked up the GTX35R to fit on the standard T3 manifold with modifications to the engine mount, worst case it will be tucked down near the gearbox but this will require a scavenge pump. Will be hanging the waste gate off the rear housing.
The automatic trans is current internally stock, just running a large PWR cooler with its own Fan and Penrite oil. Have been researching shift kits but still not confident on what will work.
The diff is from a R34 GTST - Shimmed LSD
I've been on Zeitakuvip but there wasn't much technical information, was hoping some of the VQ25 boys might have more insight.
