Is the current engine a single cam rb30 with that gear on?  That may make it harder, the inlet and exhaust manifolds may have different bolt patterns because of the different head.  If someone doesn't know for sure you can always look at an rb30 vs rb25 inlet and exhaust gasket, that will tell you if the mating surfaces and stud locations are the same. Injectors you would have to check if original rb30 ran side feeds in the same size as rb25

I don't know the microtech but again generally the ECU follows the head because that's where all the sensors are; you may well have to change this or at least the engine wiring loom as well

Ecu would need to be partial rewired and reprogramed to suit the differnt cas sensor, and coils and so on, yet can work. The injectors themselfs will work however the manifolds won't and the fuel rail.wont. Depending on if the injectors are hose tail like the original rb 30 or are proper top feed they may even just slot into the neo fuel rail as is.

    • Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf
    • Don't worry about. Just don't try to drive hard enough to make boost and you'll be fine.
    • Yes. This has already been said. It is a loop of hardline in front of the radiator. Because.... the pump is on the LHS and the steering rack hydraulic connections are where they always are on a RHD steering rack....on the RHS. The high pressure line goes down under the engine, along the crossmember, like it does on all Skylines. Don't just throw expensive braided hoses/other kits at it. Work out what is wrong and fix that.
    • Still got the afm on the intake, clamps are shut tight, only loose hose is the one that goes from the j pipe towards the IACV, since it's next to impossible to find a factory hose and the barbs are different sizes (I'm still using clamps on this hose to try and help it seal on the iacv side) I've ordered parts to make up the hotside of the intercooler pipes, I'll plumb it in and see what happens in a few days I suppose The turbo's internally gated, can I just unscrew the tension rod to let the gate open?
    • Did this ever go further ? Would love some updated info
