Pretty sure I know the answer but thought it was worth a question none the less ... is anybody aware of options to turn the VQ37 into a rear sump ? I know that on the VQ35 the pathfinder sump is an option and looking for similar for the 37 to avoid a lot of drama with my swap project. Don't think there are even any aftermarket options for a new upper + lower oil pan to transform into rear sump ?

Awesome thanks Trevor !! Watched your video and like the look of the CJ kit for regulator implementation without altering the fuel rails so I think this method will suit me very well also. Did you make the solution yourself or do they provide this as a kit ? This looks like the tap fitting, at that point its hose and fittings + reg I guess !! https://cj-motorsports.com/products/fuel-tap-npt-2-bolt

This will be on a stock ECU, hence need to replicate stock (370GT) car.

Hiya ... I'm swapping a VQ37 into a BMW and am curious about the fuel system design from factory. I understand its a return-less system with regulator in the tank with the pump set to 51psi. Does this have a vacuum reference running all the way back from the motor / inlet manifold to the regulator or is it set statically ? Is the fuel pump always on or modulated on/off or voltage changed by the ECU ? In the USDM 370Z / G37 service manuals i can see a line running from engine to regulator in tank but it does not go into what this is. I'll be looking to convert to a return system (as the BMW is) with filter and regulator in the engine bay but want to know if I need to vacuum reference it or not and if the fuel pump can be wired 'traditionally' so it will be always running via the return system. Will also need to add the fuel temp sensor which is used on the VQ also it seems.

That was the original intention however its really quite expensive due to the VVEL and to a lesser extent dual throttles / DBW. The cheapest option is the Haltech Elite 2500 which does VVEL via the OEM controller over CAN integration but does not support dual DBW so need a secondary controller (Torque Rush x2). On top of this would ideally want to make a new harness then there is wide bands and tuning ... other options from there are the likes of Motec M150 and Syvecs S7-Plus but the VVEL control becomes more exotic (direct and not via OEM controller) and tuning quite specialised. So it gets very expensive very quickly unfortunately ... hence wanting to go OEM for now if it will work without too much drama. Apparently the ECU is actually reasonably tunable so if it all hangs together I may look at a new harness once its running in order to eliminate all the crap thats not needed.

Yuuuur I do have to concede this is wishful thinking but thought its worth asking in order to save some money as its $500 NZD for the NATS removal as best I can tell.

I'm looking to find out how exactly the NATS system prevents starting on a VQ37 (from 370GT) as I'm doing an engine swap into a BMW chassis and will only be using the ECU + VVEL module. From the wiring diagrams it looks like the signal to the starter motor relay comes from the IPDM which is integrated via CAN to the BCM etc. I'm hoping that NATS simply prevents cranking via this system and by rigging the starter to fire directly off the key it will get fuel / ignition ? Hope somebody can provide clarification so I can avoid NATS removal $$

Hey all ... I'm doing a VQ37 swap into an E46 BMW. Based in New Zealand my motor and related wiring / ECU are from a JDM 370GT. Currently basing my planning work on the Infiniti G37 service manual but it appears that the wiring is slightly different to the JDM car. What a PITA !!!! My concerns are validated when comparing against the 370Z service manual which again, has slight differences in pins populated and locations. Have yet to look at it in detail but I may be able to work it out as the wire colours seem to be consistent even if the pinouts are not. However ... does anyone have the EC / engine control section (or ideally all of the FSM) of a JDM 370GT ??? It would make life so much easier.
