my very first q45a

hello everyone, just wanna introduce myself on the VSC forum...... just picked up my first '93 q45a.... been looking at the site for some time now and finally got to purchased the "G"..... can't wait to start on my build.....

be sure to do the maintenance first. no point in building a car thats going to blow an engine. don't want to scare you but the g50 is an exspenive car to maintain.
 
some things to check out:
timing chain guides
weak injectors
under plenum hoses
tranny cooler
 
check out nicoclub.com forums for more info, and don't mind the knuckle heads.

hahaha, thanks!!!! thats what my friends tells me.... but i got hella of a good deal on one that is MINT condition interior with a little (i mean LITTLE) flaw on the exterior.... 1,100 for an G50.... i think its a good deal.... 

timing belt, wtr pmp, thermosat, coolant flush, oil changed, plugs and wires will be the first......... thanks for the nicoclub.com site... i will do homework on that site and find out from there....

pics?

it's rare to see a Q45a.  now buy a data systems controller and dump that sucker.

what you think??? good deal???

im still new to this VIP game, what is the advantage of the "data systems controller" do and does to the car???? is that like an adjuster for the ride height?? whatever it is can you give me more info on this or lead me to the right direction.... much help appreciated..... thanks...... im still getting a kick out of what i got on this deal..... ehhehehehe.........

congrats on the G50, $1,100 is a good deal!  but wassup with that intake plenum?  is it me or does it look like it's corroding?

^ +1 what the heck is up with your valve cover being all narrrrrrsky? don't recall ever seeing crap like that... nice deal your Q how many miles... its CLEANNN i dream of that interior!

here's the story on the car... this guys bought this back in '00 for his parents, parents didn't like the car... he stored it in the garage 'til now.... from the title and the odometer reading... he only put 50 or so miles....... true or not thats what i was told..... just happy that this car wasn't misused in any way..... but i guess that intake turned out like from sitting too long.... gotta get my elbows dirty to polish that up.......  also\/\/\/\/

what is this "DATA SYSTEMS CONTROLLER"  ??????

very nice purchase, Ya I would definetly clean that plentum and fast.
Looks real nice and clean though, LET THE BUILD BEGIN
 
Take Care.

the Q45a is one of the rare infiniti's to come with factory air ride.  with the data systems controller you can adjust the height of your car

where can i find one?  how many positions can i change it to? can you lead me to the right directions??? much help appreciated autofashionG20

thanks,

[quote=activesuspensionsystems.com]Think of a cheetah zooming over some African veldt in pursuit of an antelope. At 60 mph, the elegant cat takes surface undulations of all kinds smoothly in stride -- dry stream beds, berms and mounds, the wallowing holes of big bovines -- and keeps its eyes leveled at its target with single-minded efficiency. The unfortunate prey swerves desperately, but the sleek feline extends the two legs on the outside of the turn, contracts those on the inside, and makes this sudden directional correction perfectly when you would expect it to tip over and roll from the centrifugal force of such fantastic velocity. If you were riding on its back during the chase (not a widely recommended pastime), you'd experience G forces during turns, but up-and-down movement would be gentle, almost the stately lift and fall of a ship over wide swells. Smooth moves
 
Now if you could only get a car to do that, actively compensating for bumps and curves rather than just dumbly reacting, you ought to really have something. And that's the active suspension concept, currently a hot topic in automotive circles. The basic idea is to use a computer, sensors, a pump, and hydraulic cylinders at each corner to get the car to do things never before possible, such as leaning into a curve like a motorcycle, compensating for the dive of braking and the squat of acceleration, and raising and lowering its wheels individually to make pavement imperfections seem to disappear. It's even been suggested that a single tire could be lifted off the road for changing.
 
Westinghouse did some early research on this back in the sixties, and Lotus, GM, Volvo and others have built prototypes, but Nissan was the first to actually put this profoundly different way of getting a car to interact with the road into production. A $4,000 option on the Infiniti Q45, it's been available in Japan for over a year now (Toyota soon followed with 300 Celicas that use a roughly similar system), and 90 percent of Q45 home-market buyers are ordering it. In the U.S., demand averaged 15 percent in 1991. While that doesn't make it exactly the most numerous thing out there, it indicates that a new techtrend is under way that you should know about.
 
I'd better mention here that although the company calls the set-up Full-Active Suspension, it's really a half-way approach because its actuators can only push. There's no power in the jounce direction.
 
Nissan states that driving fun and comfort are two of its main engineering goals. Unfortunately, where suspension is concerned they are opposing qualities -- what enhances one (firm, responsive handling) detracts from the other (soft, smooth ride). Suspension has always been a compromise because springs, stabilizer bars, and shocks are, well, dumb. But add computers, a 15 liter-per-minute oil pump, pressure control valves, accumulators, an actuator for each wheel, sensors for speed, Gs, and height and you get an integrated system that responds somewhat like a living organism. Animal anatomy analogy
 
Which brings me back to the cheetah illustration. The system's designers actually studied how wildlife moves, thus enlisting evolution into vehicular research. They make a very nice anatomical comparison between that big cat and their active suspension. The function of the animal's heart is duplicated by the oil pump, the leg muscles are imitated by the hydraulic actuators, the semicircular canals of the middle ear have an equivalent in the G sensors, and the brain's job is handled by the electronic controller. That's all very clever, but nobody's ever going to get a mechanical/electronic device to work as well as even the most rudimentary creature, much less the graceful cheetah. The best that can be said of this or any experimental active suspension system is that it aims in that general direction and crosses the line from dumb to smart. The force and the fluid
 
Mounted in tandem with the power steering pump is the prime mover of the operation, a cam-driven plunger pump with six cylinders arranged radially. The force required to drive the unit is about what you'd expect -- three horsepower at 30 mph. That's not enough to slow down the 278 hp, 274 c.i. DOHC aluminum V8 noticeably, but along with the 132 lb. weight penalty, it costs about one mpg (not so great considering that the car already carries the guzzler tax). The pressure produced, all 2,500 psi of it, exits through one-way check valves, and pulsations are damped by two gas-charged accumulators. Five liters of synthetic oil is the medium of power transmission.
 
Next comes the multivalve unit, which contains a filter and main check, main relief, flow control, pilot-controlled check, and fail-safe valves. The assembly function is basic system-wide pressure management. The multi-valve works to keep the operating pressure a fixed amount higher than that in each strut. This ensures the wheel pressure control valves have the same control sensitivity regardless of the load in the vehicle.
 
A free-piston gas-charged main accumulator is mounted at each end of the vehicle. It serves as a reservoir of pressurized oil, which provides extra flow when needed, and also maintains ride height when the engine's shut down.
 
One front and one rear pressure control unit (2 valve assemblies in each unit) meters fluid force to each individual wheel actuator. Responsive pilot-type proportional electromagnetic fluid valves containing solenoids, spools, and pintle valves handle the switching.
 
The muscles of the system are the hydraulic power cylinder actuators (MUCH beefier than ordinary strut cartridges), one at each of the four corners. Sub-accumulators and damping valves included in the actuator assemblies absorb the high frequency vibrations of the springs.
 
Springs? Well, Nissan's engineers have faith in the system, but they're not foolhardy. So, coil springs haven't been abandoned altogether. Each wheel gets one, albeit only half as strong as those you'd find in a conventional suspension. They lessen the load on the hydraulics and keep the car suspended above terra firma should the system experience a catastrophic blowout.

the active suspension system on the q45a is hydraulic not air.
 
i have read of 1 successful install of a data system controller on a g50, but it is less than ideal as far as a "slammable" suspension. according to my reading it only drops the car 2/3" max.
 
since you already have the the active suspension, and assuming you wish to slam it, you have a choice to make. do you want to invest into the active suspension system (possible rehab, maintanence, and modification) or do you want to replace the [I]system [/I](not springs/shocks the entire system must be removed and some non-suspension parts replaced) in favor of a conventional setup? either way it costs money.
 
check the vendors section for sourcing the data system controller if that is the route you choose.

thats not a 93......only the 94-96 came with the grill and that pattern on the leather.

i went with him to pick this car up... the pics of the interior don't do it justice. and the engine compartment is a ton cleaner now. we had to drain about 4 gallons of varnished gas and bleed the coolant system before he got this home. but it does look insanely good. just needs to do all the maintainance and exterior detail and it's good to go.
