i dont like the gear ratio's in that box.
the z32 5 speed is a much better choice for my target rear end ratio.
to make the most of the z33 gear spread, you need the 3.545 or 3.69 rear.
VH45DE questions
also, the TT and NA z32 trans are internally identical.
the one and only difference is that the NA has the starter slightly closer to center due to the na's smaller flywheel. if you shim it out, theres no difference.
since you already found one, it doesnt make a difference. i was just pointing out that your not limited to the TT trannys.

the only issue is the backspacing [should require a disc the same thickness as the adaper ring], but thats cake. the bolt pattern and spacing is a match.
too bad ACT doesnt make a sprung hub 6 puck clutch that i know of. that disc, with an xtreme pressure plate, and a light fly would be excellent.
overkill maybe. a street disc and xtereme pressure plate would probably be better. and easier on the trans/rear

SPEC does. You can pick those up at http://www.nipponpower.com. I got one for my Maxima and it seems pretty good. There are a few problems that I've having however I think that is all due to my clutch hydraulic system.
However... I heard RPS makes awesome clutches and such. I guess some guy had one on a 3000GT VR-4 pulling something like 600 hp or so. He'd race this thing all of the time and then drive it home. Daily drove it as well. I guess something eventually blew and he took out the clutch. After 100 or more very hard launches there was still barely any material taken off. Also, the flywheels are kind of like Fidanzas in that you can replace the friction material. I believe Nippon Power carries these as well.

it uses a 3.58 rear.
the TT uses a 3.69 rear.
the tt trans with the Q45 rear would get you some awesome top end speed. with a 275/40-17 rear tire, in 5th gear at 7000 rpm, you would be going 200 mph. all you need is a ton of top end to pull you there.
with the 3.916 i was planning on [stock for J30] and the same tires, i would top out at 182 mph. in 5th gear at 80 mph, i would be at 3k rpm.
im thinking now that i might want a taller rear to drop the cruising rpm down a little. gotta think about that one.

oh yeah, i forgot to tell you.
i called JWT yesterday, and one of the techs said that they can provide a boost program tailored to specs[ injectors ect] and they program the ecu to use a ford svt lightning MAF sensor.
also, they can provide integrated [in ecu] N2O controllers, and integrated launch control. the launch control is great, so you dont have to watch the revs on launch. just floor it and dump the clutch. im pretty sure the launch rpm is user adjustable.
also, they can provide switchable maps. you can have a setting for pump gas, and a setting for race gas. at the flip of a switch.
i think i would still piggyback it. afterall, the tuning is probably real conservative, as to cover their asses.

hmm... that would be pretty cool. I could probably just use that ecu setup and piggy back with an s-afc or something similar. 200 mph would be sweet... only downside is the Z has terrible aerodynamics so I think the fasted any of them have been is in the 170's. At the time of production the gas embargo wasn't happening so they made it with looks over functionality. 
It would still be cool to say that I have the capability to go 200 mph, lol.

yeah, i think the piggyback is needed just to be able to fine tune the car. theres no way the chip will be exact, because they will not have the exact setup on a dyno, so the ability to fine tune would be great.
also, i love the way the greddy profec E-01 boost controller looks, and the greddy emanage specifically lists the VH45DE as a supported application.

Interesting about the e-manage...
What's cool about that thing is with the proper upgrades you could nearly have a stand alone ecu.
That greddy boost controller is awesome. If I remember correctly that's the one that comes with a button that you can set to up the boost a little bit to make it act kind of like a nitrous shot. Very bad ***.

yeah, having the lcd screen showing readings [boost, plus what ever else you can interface] instead of individual gauges messing up the clean look of the J's interior is a BIG plus.
on top of that, there are 3 boost settings [low, hi, and scramble] which you can interface with an external controller, or use the hand controller. i would rewire the cruise control buttons on the steering wheel to control boost settings. with the scramble boost setting, its like getting a shot of nitrous at the push of a button because you can set it [any of the boost settings, really] to hold the wastegate completely closed until you reach a certain boost level to maximize response.
with the JWT upgrades as a base map, and the emanage to fine tune, i think you would wind up with a much better setup than programming a stand alone from scratch.
the ecu will think that it came from the factory with boost.

that setup would be cheaper, better, and easier to setup than a standalone. you dont have to worry about blowing the motor up unless you do something stupid, because the base map in the ecu will be tuned for the setup. all that is needed is minor adjustments.
if stuff gets out of whack, you just set the emanage to 0 correction, and retune. no worrying about majorly screwing up the maps.
and you will have the cruising and part throttle behavior that the engineers worked so hard to achieve. no need to try to replicate it on a standalone. they already did all the work.
besides, who wants to spend money for hours of dyno time just to get the car to run right.
600 for the chip, 300 for the accessory controller [jwt]400 for the emanage, and like 400 for the E-01 [greddy]
thats about equal to a standalone and a few hours of dyno time.
not to mention the ability to just fire the car up when your done, and drive it.
no towing the car to the dyno shop to get it running.

While searching for some Q45 headlights I accidentally came across this post that really got me enthused. I really hope this guy isn't bs-ing because that would be awesome.
From http://www.automotivehelper.com/topic52633.htm
"The VH45 weighs 3 lbs less than an L28 engine.I am currently putting one in a 1970 240Z, I have twin turboed the engine and it was dynoed at 765bhp at the flywheel @ 18lbs(on pump gas), and 950bhp @ 26 lbs boost(on Avgas 130oct).
I picked up 4 engines for $500.00 each from a place in SunValley California.Don't pay $5000.00, or 2500.00, that is rediculus, unless you are going to leave it stock and need a warranty. The trick is request a motor from the wreckers that is a trade in, I asked for ones with blown head gaskets only, so they gave them to me for $500.00 each. I did not mind them because I knew I would be modifying the engines anyway.
Now for the manual Transmission, I used a Borg & Warner 5 speed with a custom made engine adapter and 9 pound flywheel made by a company here in California. PM me for the info if you are interested in using a manual transmission.
Motor mounts, and turbo headers where fabricated by Cunnigham Racing."

Re: (IvoryJ30t)
The VK45 is 27lbs heavier than the VG30...
Just move the battery to the boot that would be 35lbs moved back and you would have a lighter front end...
