I have spent a bit of time on VG engines.

I had a maxima with a VG30DE and nitrous oxide. + tuning. It put out 264FWHP It was a great engine and they rev very freely. also quite strong.

I currently have a VG20det in my gloria and it is a fantastic engine. it responds to mods very well and revs to 8 freely.

cant say anything bad about the VG series at all. but trust me, you dont want to rebuild one!!!

I have seen/been in a VG30det in a Cima putting out 304 rwkw with a bigger turbo and injectors exhaust and cooler.

It sounded tough and had enough torque to snap your neck!

i've heard stories that they can blow head gaskets with extra boost?

this is the list of mods for this car:

*VG30DET - (STANDARD flywheel figure as quoted by Nissan Japan = 190kw @ 6000rpm & 343NM @ 3200rpm - using no intercooler)

*Custom heavy-duty engine mounts to suit

*VG30DETT 5 speed - Z32 300ZX, VERY strong gearbox, similar to R33 RB25DET gearbox internally

*Exedy Single Plate Brass Button Clutch

*Custom balanced 2-piece tailshaft for high RPM/High Speed durability

*APC (Advanced Performance Centre @ Underwood) Replacement intercooler - good for 600HP

*BMC Pod Filter - these filters are standard equipment for Ferrari with outstanding flow qualities and quality

*Cleaned and flow checked fuel injectors

*Malpassi fuel pressure regulator

*Turbosmart "Supersonic" BOV

*Cypher Industries Oil/Air Separator

*4" into 3" turbo dump pipe

*3" exhaust system with high flow cat

*EMS-QI-4 with version 7 upgrade including Lambda control, data logging, laptop programming with all software and **HAND CONTROLLER WITH FULL DISPLAY**

I'd be interested to know how this was done.....the VG30DETT 5-speed has some design features that make it _very_ difficult to fit to any vehicle other than a Z32. For example the starter motor mount is unique and would definately require considerable massageing of an R31 firewall and trans tunnel to make it fit. Not saying it can't be done, just curious to know how.

the very first line of info on the car from the forsale thread was,

"over $11,000 spent on engine conversion alone (not including parts)" so i assume that means alot of time and fabracition....

    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks  
    • Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
    • I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
