1986 300 Zx specs needed

[92rs25th]

I'm looking into buying a 86' turbo 3.0 v-6 datsun 300 Zx 5 - speed for 1500 and it's in almost perfect condition. I was wondering what some power specs are on the car and what are some pros and cons of the vehicle.

I'd appreciate the feedback , Thanks !

well im told through my research its about 200 hp at the fly wheel and 170 to the ground
and as for the 1\4 is about 15.4
and 0 to 60 is 7.4
the numbers arent exactly outragous but can be helped a bit with the right mods and

for a list of some of them just go to z31.com

and ive found a few tricks like an externally mounted spring instead of bleed off theres also another method where the bled off air goes into the charged side of ther pipe also but the springs is cheaper but anyway if you dont wanna mod it i dont wanna rave it

the stickies have all the information you'll ever need... if you can't find it in there or by searching the forums, try z31.com, and if you still can't find the answer, then ask...

Thanks for the info , I am selling my camaro and want a lighter - 5 speed - car and the fact it's a turbo was a bonus.

I plan on modding the living hell out of it but I don't know any performance parts for the Datsun , I've always been a camaro and prelude guy.

your on the right track. Plenty of guys here that can help you, and have lots of knowledge on the very car you interisted in.

yes we can im new to the 300zx but am learning and have learned some good mods to start out with

i recomand that you start w/ the intercooler.. it's really hard to find a cheap intercooler for z31. the cheapest is speraco intercooler. i got it from http://www.expressautoparts.com for $635. 7inch h, 20 inch w. 2.5 inch piping.
what i started w/ was the boostcontroller. that was really bad.
so no boost controller w/out intercooler or you will pay alot to fix this z31. z31 parst are soooooo expen$ive.
then you can get HKS exhaust system. it's really nice. good sound and will give you around 10 more HP. cost around $350.

buying intercooler kits, i've figured by now, is for chumps... buy the intercooler seperate... save yourself like $300 bucks and get the aluminum piping bent up by the local shop... as long as you can use a measuring tape and have half a brain, it'll work out just fine... hell you could even take out the plastic pieces and bring it into the shop with you...

you can save a whole lot of money just by researching something and doing it yourself.... anytime you buy something brand name or in a prepackaged kit... you're paying way more than you should be...

just my .02

well actually a intercooler is not a needed item unless you plan to exceed 8 psi i am told and if you get an aftermarket ball bearing turbo it raises that number higher
now the reason being that you lose a slight amount of boost andf the chargde is cooled only so much so the result is that you boost the turbo up more to get the same psi and as a result the turbo has to woirk harder so unless you go aboce 8 psi then start with the exaust then the intake then get a boost controller and go to 8 psi
if still not enough power get the intercooler and go to 10 i dontr recomend going past 10 without an intercooler at any time unless yopu have really high octane then you can hit 12 usually with little or no problems
good luck and is it electronic controlled suspention
and does it work if it is???
mine is and i love it just dont hit too many bumps at 110 and try and slow down aty the same time in firm lol and also dont try and switch the position iof the knob whil;e hiting bumpos it usually sets mine into fail safe mode (all lights blinking on the knob)

I wouldn't waist my money on a intercooler, unless one was already installed is not as efficient as water/alky injection. With a IC, when you run high boosts you have to retard the timing to help keep from detonation. With water/alky injection you can advance the timing and also run more boost. Advance timing=power.

Can I get a waste gate and a turbo timer for this car ? I heard just getting a turbo timer can give you anywhere from 5 - 15 Hp.

I also want my turbo to go woosh. =D

To my understanding , the guy that is selling it has done a few things to it I guess like a K&N intake or whatever and a kevlar 5 point clutch , adjustable suspension which was like 800.00 and thats about it.

I just want the 0-60 to drop down to abuot 6. - 6.5 seconds. 7.4 seconds is too high. I know it has like 200 hp and 227 ft lns torque but is it possible to push them up to 250 Hp and around 280 ft lbs of torque without having to touch the internals or do any ECM tweaking ?

I don't know anythign about these cars but i'm willing to put forth the effort and some money to try to get her down to 12 seconds .

yah.. that's what i said before" i don't want to waist my money on the intercooler" guess what. I paid more than the intercooler cost to fix my car because of the high boost. i was running my car w/ 12 boost and had alot of problems. paid almost $700 for parts and labor... get the intercooler if you think about higher boost. it's the first thing you should think about. i have 3 Zs. and I have ouned 7 Zs in my life... for z31.... you will have alot of problems and some parts are hard to find in good shap in junk yard..

[stephenp]

well z 31 . com will give you instructions on how to acheive that and as i said you can get the externally mounted spring in place of the boost controller and just pik up a boost gauge (liquid filled psi gauge going to atleast 15 psi (make sure you dont try and max it that will pop your motor in a sec but anyway

yes you can easily mod it to get 250 horse and the cost will be under 500 for those mods and it sur does make a snappy difference im not sure how acurate \his numbers are i did that amoungst others to mine and hmm sure is quick but i also did weight reduction also alot of it at that but you shouldnt be unhappy with your purchase

and for comparison my freind has an 89 camaro 305 5 speed that is actually about the best running 305 ive ever seen buit any way i smoked him in my 86 naturally asperated and my turbo made him look like a joke


and also to add to your list of mods get an electric fan in place of the mechanicle and ditch the ac and if you dont mind no pwr string that can go too but im the only person who seems tio feel that way everybody else says they prefer to keep it .... not me
and replacer the timing belt ...
do it by first taking off the valve covers and loosening the rocker arm shafts to prevent harmful spinning oif the cams causeing bent valves i found out the hard way and i still wannna cry but that was the na now i only need bearings for my turbo and im good to go

You didn't read my post. I said use a water/alky injection system. Better cooling and no restrictions. Been using it an my street Z and running 20+lbs boost and never had 1 minutes problem with it. Anyone that runs high boost without some sort of cooling will end up with problems.
