Guest MARKTURBO Posted June 6, 2007 Share Posted June 6, 2007 Hi guys, What 5 speed manual gearbox can I use to run a VQ30DET in rear wheel drive. What vehicle would the donor be from? Are adapter plates required? Any comment would be great. Thanks Quote Link to comment Share on other sites More sharing options...
nismopu Posted June 7, 2007 Share Posted June 7, 2007 why not get a 6 speed from a 350z? Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 7, 2007 Share Posted June 7, 2007 That I know of, there was never any 5-speed offered with the VQ30DET. It would definitely be nice as the 5-speed would match a boosted VQ a little better than the 6-speed... but, the 6-speed would be your only option unless you go with an adapter plate.

Guest Flintstone Charlie Posted May 11, 2008 Share Posted May 11, 2008 Good Morning All, I'm exploring the concept of a VQ30 swap into a Roadster. The engine should be a reasonably easy fit. The challenge will be the transmission. The Z 6-Speed will have an interference issue with the frame. For those of you not aquainted with the roadsers, they are built on full X-frame rather than being a unibody car. So, the transmission fitment concern isn't so much a length issue as the transmission width at the tail. Of course, steel is negotiable and I could modify the X portion of the frame to provide the needed clearance. However, a more logical route might be to work out a 5-Speed setup via an adaptor. So, what might be the simplest transmission to adapt? How is the bellhousing pattern of the VQ different than the VG or L engine? What does it take to adapt the transmission? As I understand it the Z 6-Speed is the only RWD transmission that will bolt up. Correct? Obviously the Pathfinder has RWD. Is transfer case seperate from the transmission or is there a 2WD confguration? I'm guessing not since I haven't found anything anywhere that seems to offer it as an option. Does anyone know if there may be a frankenstein transmission option? Something like a Pathfinder front case half bolted to a RWD version of the same tramsmission? They do SR 20 swaps on these cars without a great deal of modification and in some ways the VQ looks like it might fit a little better. Thanks in advance for any ideas. Obviously, since I'm contemplating putting a VQ in a roadster I'm willing to enertain even crazy ideas.... Charlie Quote Link to comment Share on other sites More sharing options...

260DET Posted May 12, 2008 Share Posted May 12, 2008 The obvious box to look at would be the Z32 5 speed. Its strong and still available new. Alternatively a Tremac? Quote Link to comment Share on other sites More sharing options...

That would be sweet... brand new gear box. I'm sure the rb25det box is still avail new if the Z32 is...?? The million dollar question is.... how much??

260DET Posted May 13, 2008 Share Posted May 13, 2008 US$1850 for the Z32 box according to this http://www.aus300zx.com/forum/showthread.php?p=666412#poststop Quote Link to comment Share on other sites More sharing options...
