Do i really need all those expensive parts to lower the Z? i was just thinking about buying the KYB adustable shocks since i already have the eibac springs. the car hops alot in the bumps and feels like its going to brake apart in some small holes but even worst The car is bounds alot when i past over 110 mph and that really scared me once since these highway in NYC have several pot holes and you never know when you going to fall in one. So my question is will i be alright if i Just buy the KYB shocks and use it with my eibac springs or should i buy somthing else?

sounds like shes a little stiff, and has unmatched shocks to those springs(or just whore out) and sounds like you want somebody to reassure you that this wont happen so all i have to say is good luck and not familiar with the z 32 to be specific so i dont know what would be intailled in creating a safe high speed car is it na is it tt how many mioles what has already been replaced ? all input helps

i dont know exactly what has been replaced. I bought the car a year ago and havent really taken a good look at my suspention. All i was able to see id that it has the eibac srpings but the shocks i couldnt recognize. The car is a 91 2+2 with 130000 miles in it. Im sure i need new shocks all i want to know if ust putting the Kyb there will be a good buy or while i replace the shocks is there anything not too expensive i can add to the suspension to make it hadle atleast like the original setup. All i want is to leave her low to the ground like she is right now.

First off you need to understand the Z. It's a hi-performance car. Meaning the engine and suspension are tuned to a higher level than a normal car.
By changing the ride hight of the car changes the geometry of the suspension, both front and rear, as it's a 4wheel independent suspended auto.
Your handling problems is due to improper geometry.
To correct it you'll need to install the parts that can correct this, and while at it would be a good time to install hi-performance bushings. Then you'll have one of the best handling cars on the road or track.
Best way to check the car is at speed. Speed amplifies incorrect geometry, but it can also get your ass in trouble. Meaning if you get into a high speed fishtail or wabble and your not experianced in such things, you could end up bending you nice car or your ass.
Do it right and you'll have a great car.

lile zgringo was saying...you need a compensation kit to reconfigure your cars "geometry" back into stock specs. check out the Z resources sticky. there should be a couple sites on there that sell it...

and to answer your queston about the shocks...yes, your in need of new shocks, i guarantee it. and yes adjustable KYB's are a very good choice.

droppin the science like bill nye the science guy! :lol: Im learnin bout that right now in school, SLA and Mcphearson, leaf springs, doublewishboned suspension, all that jazz.

Good, then you can correct me if I'm wrong, better yet, start answering some of these questions. Bill Nye was my 1st grade teacher.j/k:grinno:

Speaking of suspensions I have a quick question for you Albert.

A TTs rear swaybar is thicker than the NAs rear bar right? Then if I were to swap the swaybar on the rear of the car to a TTs swaybar I would dial some of the understeer out of my car correct?

where you going to school at BlackBettyZ..

yah i learned about all taht in school but i kinda forgot some of it lol

I think your right but I don't know how much as the TT has that 3 degree steering rearend.

would it even mount up??? and anybody try and drift with it yet? lol

drift with the 3 degree steering rearend that is lol no any body ever try drift with a oversized sway bar lol it helps a bity lol but with the rear steer?? hows it work out good or bad??

New england technical institute. I got 15 more months of school, then i want to go into the field for 2 years, then get a master technition degree, at UTI maybe specialize in Benz, Porshe, BMW, Audi..

Well BBZ, let me tell you about the UTI grad programs. 1- dont even think about Porche if you missed 1 single day of school in that 15 month period and you are carring a 4.0GPA and have about 18months experiance in the field first. Benz is a lot easier to get into but they are becomeing flooded with techs no one is hiring them in alot of areas. Same for BMW and Audi. VW and Volvo on the other hand are screeming for techs, they need them they want them and they are willing to do anything for them. Not to sound kinda mean but with alot of the forign manufacturers they dont care if you have a Master cert ASE they want to know do you know how to work on THEIR cars THEIR way. Volvo for example doesnt pay extra for ASEs but they pay more for Volvo certs. I have quite a few of those. But I still havent found a place to hire me yet becuase of location and scheduling conflicts. Then you have to take into account if you go to any of the grad programs at UTI you have to work for that manufacturer for a min of 1 year or pay back however much tuition was for that program. They get pretty lofty let me tell you. I am speeking from experiance I am a Volvo SAFE grad, I have freinds who are Benz, BWM and Audi grads. 1 of them had to pay back the 9K tuition for BMW becuase he went to work for Nissan instead and loves it there.

Shit im paying $30,000 in tuition right now to get my technition certification. You went to UTI? for the Volvo SAFE program? how long was the course? and how much was it 9k? You just shotdown my dreams of workin on 911s.. :(

drift with the 3 degree steering rearend that is lol no any body ever try drift with a oversized sway bar lol it helps a bity lol but with the rear steer?? hows it work out good or bad??

Why is it lol? Some of the best Porsches had it. lol. Escore in Japan drifted with a Z32TT and won the nationals. lol. you have any idea what a away bar does? lol. It isn't worth shit for drag racing, but for cornering, does a pretty fair job. lol. I don't think Nissan engineered it into the Z32TT cause it was bad. lol. But I don't think Nissan had drifting in mind when they designed the 300ZX. lol.

i cant imagine drifting with the HICAS system enabled...that would kinda defeat the purpose.

they make HICAS eliminator kits which im sure anyone who wants to drift a Z32TT would want to invest in...

But I don't think Nissan had drifting in mind when they designed the 300ZX. lol.

Your so right K3. You'd be better off just swaping the whole sub frame for a N/A. Besides better gearing. Anyone need some good HICAS systems I have 4 laying around. I figure they'll make a good boat anchor.

hey alpha, i live on li... where in nyc can you do 110??? not till you get out by me... i haven't read too much of the post yet, but i'm sure i'll edit it soon!

hmm i can get up to 110 pretty quick ....


yah so my car doesnt idle worth a damn now it doesnt matter what temperatur the ambient temp is and im thinking its my MAF or TPS sucks i gotta keep it throttled at stops and shyt lol and on the sidenote i have that freakin loud exhaust leak on the left bank its getting worse but i supose when the $$ comes itll get fixed lol ...


yah so i finally got my a/c compressor out of my car and the lines which the compressor was a biznitch took the downpipe off and got to it easier and took out the inlet pipe to the turbo also made it easier...

110 well any highway stretch at all will work
considering in my z31 i get 104 or so in 3rd and speaking of that i hit 7000 rpm in a clutch dumping show off poiwer burn
shouldnt my cut off rev limiter and such taken over before that???

i dont think the Z31 has one...your not gonna want to over rev your engine. thats why they put a redline there, it means stop!!!

lol yah well nolonger have that idle crappy job anymore it was a massive vacuum leak on downtube goin to sumn else it was unhooked ...


but it doesnt wanna idle in gear and it is dependednt on ambient air temp so when its warm outside it idles fine in gear but the cooler it ius it wont idle in gear its just fine in park and neutral so i was thinking maybe it was my MAF if im not mmistaken the z31's had the hotwire type maf..

anyone else with a z31 had this problem ,if so what did you find??

well here in NYC we have several highways that have good straights. For example the bruckner coming from City island going to manhattan we have a good straight in there some where. Honestly i have done 130 but that was a while ago then i did like 135 on the sheridan coming from manhattan and going towards 180 street Boston road there is a nice straight there and even better is going down hill. And most of the time i have done it is during nights at around 1 or 3 am when there is almost no traffic. I now i can do more than that but i always stop at those speeds since im not too experience driving at those speeds plus the straight end and i have to be prepared to stop. IF you live close come over and i will show you this aint no bull shit if you know anything about the highways im talking about and the locations i pointed out you know those speeds are possibles. they have more than a two mile straight and coming at about 80 or 90 before hitting them you know is possible.
