There is no manual transmission that bolts directly to the VH45 IIRC.

You, me, & about half the Q45 owners out there.

450zxtt put a VH45DE in his 300zx & made an adapter to bolt his 300zx transmission up.

Don't know his name, but a Z owner made an adapter to fit a T56 to his VH45DE. (For an early Z car if I'm not mistaken)

There is someone with an S12, (I think), that dropped a VH45DE in but I'm unsure what transmission they used. (Was it you?)

I'm currently working on an adapter for a KA24DE transmission to bolt up to my VH45DE, but it'll be well into January before I'm done.

Use the search button up top & you can find a little info on hybridz.org in the "Other V8's" section.

Nothing bolts, but anything can be made to work.

Because it is big, heavy, electronic, weak and will slip with 600 rwhp and then break!

Sounds like a good reason to upgrade the transmission to me.

Omega Motive is in the process of fabricating bell housing and flywheel adapters for the R30a 5spd 300zx transmission.

Are these the guys that sell on ebay? I contacted them about this a while back.

RB motoring out here in CA is also (supposedly) building an adapter for the 6-speed 350z transmission.

But I don't really want one of those, because they're weak.

I think the race is on to see who will have a 3-pedal G50 first!

With a T-56?

I still like Sijoko's suggestion for the 6 speed GM automatic.

Worked great in my 68 GS. 400 rwhp and a beefed-up PowerGlide was fun as hell.

Wanna see a Corvette owner wet his pants? Pull up next to one at 50mph, drop it into 1st gear and leave his a$$.

I'll agree to that. For straight line racing you CANNOT beat a properly built PG with a custom TC & manual valve body...

I've even seen them used on roundy-round cars with a coupler in place of the TC.

I have a friend with a GN T-type with a PG. He builds like 20psi of boost against the converter on the line, shifts once and does hi 10s allllllll day long.

The Z guys at HybridZ.org sometimes put q45 motors in their old Z cars to keep it all Datsun/Nissan. One guy there builds adapters for the vh45.

I am pretty sure that the guy that you are referring to is Slim. He is the one that put the VH45DE in to the Z32.

The last I remember, there wasn't enough interest in the adapter for him to make a batch.

I am not too crazy about the gearing in the Z32 trans anyway. You would get better acceleration but your cruising rpms would be too high.

That's the reason that I had posted the topic on the 6l80e. To me, a six-speed auto might be the best compromise.

You won't have to deal with figuring out how to get the pedal assembly in the car nor deal with shifter location issues. You would have to use an aftermarket controller to run the trans. Of course, you have to work out the bellhousing situation but that is a given for any trans swap.

GM is coming out with a heavier duty version of the same trans, called the 6L90E. This is supposed to go on their bigger trucks. It is supposed to be the same size as the 6L80E which they are currently using in the Cadillac STS-V and in the new Escalade and Yukon.

I don't care if my Q45 has a GM trans, since the stock trans is not made by Nissan anyway. If the 6L80E trannies are reliable, then it would be a good candidate for a swap.

Interesting points.... the difference in RPM is only about 8% different.. (.75/.69=1.08). So at 60MPH youll be going about 160RPM faster (2000x1.08=2160... hardly noticeable.. Plus, youll be dropping weight, and the clutch is more effecient that a torque converter, especially a high stall converter..... In theory youll be turning more RPM but i think real world highway cruising will be a wash....

I wonder if you could swap in a lower 5th gear, like .55 or something. thatd be nice

I think the 5 speed in the Q isnt gonna be that hard, really. I think the first half of the Q45 driveshaft and Z32 driveshaft (TT) are the same length... Which means, in theory you could take the 2nd half of the Q45 driveshaft and mount it to the 1st half of the Z32... It may work, it may not...

I did the calculations for the shifter, and the shifter is gonna be DAMN close to the stock location.. Its about 29in from the bellhoursing to the shifter, and thats roughly where the shifter is currently is on the Q (from the firewall).. I think it will be really really close..

The Z32 pedals can be utilized. Youll have to relocate the cruise control servo but you can get a MC in there... Thats where it is on the Z32.. If the Z32 is too big you can use a maxima one too, those are a lot shorter...

The stock E brake needs to come out and the stock Z32 pedal can go right in there (clutch pedal)...

I've spent a lot of time looking inot this, I'm not pulling this out of a hat.
