Timbos 85ZXT and 87ZXTHowdyIve had her for about 3 years now,mods include: 86 Turbo ecu T3/T4 hiflow turbo Early 90s Maxima engine Intercooler King low springs Thats bout it,got another auto in the shed im gonna rebuild and mod so it can handle the power.Old one is making some scary noises...Heres some pics 
The one with the higher lower output is from the old setup,a T28 from a skyline,no intercooler.The 118hp graph is stock standard,bout 2 years ago.The current setup makes 177rwkw.The video down the bottom shows the making 
Yeh,u get the idea.. 
The top photo is the day i picked up the car,the bottom one is the current stup 
And this is the old setup with the T28 I also got a video on youtube,ill grab the link in a bit.Its got more pictures and the latest dyno run at the end. |

Bit of fun in the rain,quality is kinda gay tho..I put my phone between the headrest and the seat and recorded on my way to work one day  ...

Bit of an update,pulled the old auto out prematurely coz it was wrecked and was going to replace it with another auto..I decided to bite the bullet and throw in a manual while its out.Ever tried replacing an auto when the cars on stands?Its not fun..Hope it will be done in about 2 weeks. | ||
| Timbo_021 |
Soon to become "Timbos 87ZXT"

| Slade |
Looks like I am leaving it in good hands too. Make sure you keep posting updates, I wanna see what you can do with this car. This 87 would look awesome in black by the way. | ||
| Timbo_021 |
Yeh,for sure..Got lots of plans for it.Ill post up everything i do so u can see how it goes.Wish i still had the number for the people i bought the 85 from,they would love it.. | ||
| Timbo_021 |
The day she arrived at her new home.. Fixed the drivers door not locking,central locking now works and enabled the alarm noise box again.Gonna start taking out the injectors tomorrow night,looking into ordering new fog light covers because the ones on there are melted :S and started putting my stereo in there too.Ill get more pics up soon |
||
| s2k12 |
wow, looks like you got an awesome buy! | ||
| Timbo_021 |
Yeh,i think i was very lucky..Tonite,going to clean up all the ground points on the car,put in new bonnet struts and start removing the injectrs. | ||
| Timbo_021 |
Cleaned up most the grounds,put in my turbosmart boost controller,fixed a few vacuum leaks (have to replace all the lines) went to the car wash..Still randomly misfires.I have traced it down to a voltage problem.When driving in the dark with headlights on,if i turn on the fan or demister the headlights will dim,dash lights dim,tacho drops and engine misfires more.Im thinkin maybe battery is buggered and the alternator has to cover for it,hence the dim because of the delay for the voltage regulator to pick up on it...Gonna try another battery tommorow.
|
||
| s2k12 |
ahh nice. along with a few other cars ive seen lately, this is motivating me to do the little things on mine to get it working between now and rebuild time. | ||
| Timbo_021 |
Howdy
Bit of an update..Replaced nearly all the vacuum lines under the bonnet.Doesn't blow permanent hot air now,vents all work and the cruise works now too.The vacuum line that was on there slipped off the nipple so thats why it would activate and all but not do anything..New injectors are in,doesnt stink like fuel anymore and now zero chance of an engine fire,thank christ..Never want a repeat of that.So now,im gonna install the stereo on the weekend,all new wires run to the speakers and everything,bit of time involved there im sure..Then,next weekend im going to attack the rear main.Its leaking pretty savage,must have come loose im thinking and got torn to bits..Took like 4 hours to swap the stupid injectors,dang theres alot of crap crammed into that engine bay! |
||
| s2k12 |
How much did they cost you, and from where? Are they the same as vlt ones like ive heard? |
||
| Timbo_021 |
Yep,80 bucks each from Bresciani Racing.I got told that they were going up in price very soon when i bought them about 6 months ago. | ||
| s2k12 |
Ahh ok thanks. I guess if more than half the injectors in my parts car are fucked I'll just look for a set of vlt ones second hand then.. Unless I can afford gtr injectors or something. | ||
| Timbo_021 |
Do not get 2nd hand injectors under any circumstance.I got a set,got them tested and they were fine.Put them in the car and the bastards leaked.Getting them tested isnt enough,they dont go through the same conditions as on an engine.Just get brand newies or rebuilt ones..Please?lol.. | ||
| s2k12 |
Haha really? Hmm.. Might compromise and get a set second hand from an importer with a warranty lol. | ||
| Timbo_021 |
Put the stereo in,sounds pretty dam good.This Z i found has alot more sound deadening than the old one so that helps a bit.The old stereo was done professionaly so it wasnt too hard to put in the new headunit.Id say mine looks more professional than the old one,what do u reckon?Put Alpines in the rear and Pioneers in the front,think they are 200W speakers.Sony sub in the boot,gotta get a smaller box coz it looks like crap..Pyle Driver amp.2000W max and 1000W RMS.Headunit is a Blaupunkt,changed the color of the display to match the rest of the car.Took an entire day to put it all in,new wires to all the speakers..Glad its done tho.Ill get pics soon,just uploading them now. | ||
| Timbo_021 |
Old wiring,messy lookin.. 
New wiring,nice and neat. 
RCA cables done 
Installed,sorry bout the blurryness 
The amp,seats still fold up.The sub sits right behind it. 
Rear speakers,the original speaker covers still fit over so hides them nicely 
And the fronts. |
||
| Timbo_021 |
Put in most of the Prothane bushes.Only ones left are front lower control arm and rear control arm bushes.I lack gas for my oxy so im just gonna do it at work this weekend along with the rear main.Mite also do the camber mod that i found too as i dont think its been done yet.Drives awsomely tho,ill whack up a picture or 2.. | ||
| s2k12 |
Cool, let me know if the Prothane bushes are any good, I'm close to buying some. | ||
| Timbo_021 |
Only thing im not so sure about is the rear swaybar bushes.Seem to be too big,swaybar measured 22mm,pack said 22mm but they are too big.Doesnt thump around or anything tho...AND,us Aussies got skimped again with our cars having 22mm swaybars front and rear and no lsd...Rigged!! | ||
| Timbo_021 |
Front passenger swaybar mounts.These are snug as against the swaybar,unlike the back.. 
Front passenger strut arm,they all it on the pack.I call it a caster bar.. 
Rear looks pretty hey..The old bushes werent so bad,i dont think they were originals. |
||
| s2k12 |
Nice, nice.
Hmm.. Something I never really thought about, I spose a thicker swaybar would come with its own bushes then yeah? I was going to get msa 25.4mm (1") swaybars and put them in at the same time as the prothane stuff, after the respray.. |
||
| Timbo_021 |
If you order the whole Prothane kit,all the bushes should come supplied.I got 22mm,23mm and 25mm,26mm bushes..Just round it off i spose and put that bush on.Unless they make custom ones? | ||
| s2k12 |
Ahh ok cool, so you got all of the different swaybar sizes with the kit?
Where'd you get the kit from? I was looking on ebay usa.. |
||
| Timbo_021 |
Came with the car,would have to ask Slade where it came from.I think the US but not sure..Box is outside,ill hav a look when i can. | ||
| s2k12 |
ahh ok cool, cheers. | ||
| Timbo_021 |
Yay,doing the rear main tomorrow and hopefully install the rest of those bushes..Also,does anyone have the power to rename the topic?Id like to add "and 87ZXT"..
Thanks |
||
| s2k12 |
Haha yep, me and you can both do it. I'll do it for ya tho 
|
||
| Timbo_021 |
haha,awsome as!!Gotta show me your bag of tricks one day | ||
| s2k12 |
Haha click edit on the first post, and you can change the title there.
Oh yeah, I can make people say anything lol
|
||
| Timbo_021 |
Well,pulled the gearbox out today..Wasnt even the rear main leaking..Grr..Was the sump leaking between the gasket and the block right underneath the crank..So whacked a heap of sealent around there and done up the bolts which were like finger tight,seems to have fixed it..Its also got an Exedy clutch disk in it,looks pretty new.Standard pressure plate though which has seen better days.The extra flywheel i got with the car is also different to the one on there,little smaller, so binned that one,gotta find another replacement soon because this ones got a crack through the ring gear.. | ||
| s2k12 |
could either go z32 items and get them machined to fit, or z31 items which would need to be bought in from america. remember that s3 turbos have a 250mm clutch & flywheel, which is 10mm larger than all na's and s1/2 turbos.. on international models atleast, who knows what they did to aussie ones lol.
i wish my car had a clutch lol. |

| Slade |
Looks like you've been busy Tim. I am glad it is getting the attention it deserves. 4 hrs to change the injectors, that sounds more like it. I knew something was up when you said you took your old ones off in 30min. Have you put your turbo or the intercooler in yet?
The prothane kit I bought online from http://www.thezstore.com/store/merchant.mvc? the online store for motorsport auto. I think I got it for $140US? If you guys ever need parts for the Z, check this site or even courtesy nissan. I found it alot cheaper to import parts from the US. I even got some parts from ebay, such as a crank angle sensor for about $40. It was an aftermarket piece but it was brand new. I started getting parts like this after going to a local Nissan dealer and being quoted $600 for radiator and heater hoses. I ended up buying them from the z store in the US, and got them for about $200. When I opened them, they had a made in Australia sticker on them. Tim, have you adjusted the timing belt yet? If you haven't done it, you might want to consider putting in the cam gears from your old car. I remember the hole for the pin in the cam gears were a little worn. Also are you sure its not an LSD? I remember you asked me if it had a viscous LSD, that was only on the US SS (or Shiro) model. As far as I knew, it was a clutch type LSD. If it no longer works as an LSD, maybe the clutch is worn. Strange that we go smaller sway bars here too. I am still looking for a supra, but I am going overseas soon and probably won't get one until I get back. I am moving back to Brisbane then, so that should make it easier. Its a bit hard trying to get around Australia to look at cars when I'm stuck in Tasmania. Good work with the car, keep posting on your updates. |

| hts31z |
...hey dude, good job looks like u have been pretty busy with it, your new Z looks great tho, umm i was just wondering how much boost u are running, and did u dissconnect the boost sensor or what do u do there??? |
||
| Timbo_021 |
Boost sensor?dunno what drugs ur on man...lol.Boost is on 4mmhg or whatever the stock boost gauge language is with a manual controller...
Slade,havnt put my turbo or anything on it yet because im going to register it first and all that crap..Then i can go do all that,dont wanna do all the work and then not get roadworthied for whatever reason..lol.Registration will hopefully happen this week,pending on if i need to install a muffler on the exhaust or not. Ill have to take off the diff cover and have a look in there,if its an open diff i mite try putting in a 180sx lsd again.Didnt work last time because i had the wrong halfshafts..Should have kept the damn thing.. Timing belt i havnt done yet,the timing gears are going with the other car because im leaving the engine in there.Only reason i was going to keep it was incase the engine in this car was a little sick but its perfect so dont need a spare..Ill make a trip to the wreckers and get a set of gears.I designed an adjustable cam timing system a while ago in CAD that i might try to get done at the same time. But yeh,ill keep you up to date on whats going on. |
||
| hts31z |
little black rectangle box on passanger side inbetween the headlight n the strut, has a plug and a vaccum line to it
(says boost sensor on it) |
||
| Slade |
Yeah, disconnect that and your car will run exactly the same except the boost gauge won't work.
Stock boost on an Australian z31 is about 7psi (about 360mmHg). To increase boost, you need to remove the pop off valve (POV, not to be confused with a BOV, z31's don't have those), and install a manual/electronic boost controller. 12psi is considered a safe boost level by most, higher than that and there is a risk of detonation unless an intercooler is used. I think it is around 14.5psi when the injectors reach maximum duty, which means you will run lean and increase the risk of detonation further. |
||
| hts31z |
arr thanks, im not running the standard boost guage so thats all good, i have an intercooler, and have plugged the POV, n put in a bov..
looks like ill be runnin 12-13psi, cheers |
||
| Timbo_021 |
Done!!
Well,bout 90% done.Need to weld on a bung for the idle control and one for a breather and bam,complete.Come up alrite,what you reckon Slade,look like something you had planned? 
|

Theres the making of link. |

Bit of a vid also |
||
| s2k12 |
Looks awesome dude!
Now we need to see vids of it on the road and/or track
|
||
| Timbo_021 |
Ha,was gonna record my drive before but got too excited and 4got..lol.Dose sounds mean,i mite try do something tomorrow night with the phone and gaffa tape.. | ||
| s2k12 |
Haha cool. | ||
| Slade |
Hey Tim,
That looks like how I had it planned. Have you considered plating over the idle controls, or venting the breather to atmoshere? Might save a bit of welding anyway. I think there are actually 2 idle control devices, one on each side of the intake plenum, so you will need to weld 2 bungs. I can't quite remember the reason why it uses 2, seems strange to me. I think the passenger side one allows the regular idle speed to be adjusted and the other one controls the higher idle speed from cold start up. The one on the drivers side is fed by an air hose that runs around the back of the engine through the larger of the steel pipes. There is no real good reason to get rid of idle control, but it does clear up the engine bay a bit. Did your old car have a BOV that you can put in? Have you loosened that timing belt yet? Sounds a bit tight in the video. So I guess you got that electrical problem sorted out. How did you fix that? I just got back to Australia last Thursday, and will be living in Brisbane again. I will continue looking for a supra soon, and probably visit an importer next weekend to get something shipped in. Private sales have just been a pain in the arse so far. If you got any stories or pictures from targa Tasmania, send me an email sladewormington@hotmail.com |
||
| mr camouflage |
What sort of supra you looking for? A mate of mine is selling one. | ||
| Timbo_021 |
Yeh,timing belt still needs to be loosened off a little.Ill do that tomorrow beacuse the cooler pipes have to come off anyway to get to it..Other car didnt have a BOV, but i like the sound of the dose so i might keep it.Grabs alot of attention down the main street..lol..Wouldnt really expect it from a 20 year old car.Targa was freakin shithouse,boring as hell it is down there.How did you survive that long?lol..We came 22nd outright in a CV8 monaro.Was 300 competitors so not too shabby.. | ||
| Timbo_021 |
Loosened the timing belt tonite.Was fairly tight..Reassembly was halted due to me painting a couple things to bling up the engine bay a bit..
Also Slade,you wont believe how close you were to fixing the electrical problem..Was the harness going from the CAS to the engine loom.Its playing up a little when cold but only just recently so im gonna have to look into it again.Hopefully on the weekend ill be able to chuck it on the dyno and see what happens
|
||
| Timbo_021 |
Hitting the dyno in a few hours.Fingers crossed for around 200rwkw.Wish me luck
|
||
| Timbo_021 |
Righto,output is 174rwkw at 9psi.Thats 2 psi lower than the other Z.Still has plenty of headroom,reason that we didnt wind the wick up is because it spikes pretty bad to 13psi and runs a bit lean down low.So gonna get another wastegate actuator and a fuel pressure reg and the dyno man reckons we could get around 220 at the wheels. | ||
| s2k12 |
Nice one dude! | ||
| Slade |
I can't believe that was all it was. I saw the ECU doing some funny things too so I thought it must be a power supply problem. I think I even tried to get a new CAS harness from Nissan but I can't remember what happened. I never got a CAS code either. Errr, how much will you sell the car back for now?
174rwkw is pretty good. What exhaust have you got on it now? This is with the stock turbo right? I would be really interested to know how much power this car was making when the idiot owner before me put the bleed valve on the wrong way (the waste gate wasn't opening at all . . . . 22psi?). I'm glad I corrected that. it was fun and all but I don't know what strange law of science was stopping detonation. Its insane really, stock fuel supply leans out at 12psi, and there was no intercooler! As for surviving in Tasmania, take your car next time! The roads there are awesome to have some fun on, and great scenery. A guy I work with had Simmons Plains for the whole day last Friday. Drove his twin turbo Z32 until there was no break pads left. Apparently, it cost about $120 for the whole day, but I don't know if that was mates rates or what. |
||
| Timbo_021 |
Ha,thats freakin mad bout simmons..Yeh,after doing Targa i saw alot of real good roads and scenery around Tassie.Ill have go on a bit of a trip one day with my mates..Sorry man,still got a bit i wanna do before i sell it..lol.Stock turbo is still on there,its not really struggling so ill leave it till i get bigger injectors,fuel pump,fpr and a nistune on there.Exhaust is still the same but with a straight through muffler on the back.Thinking the gearbox needs to be looked at soon,makes some concerning noises when its cold.
But yeh,it is really wierd that it didnt detonate with no wastegate action,lol..Im looking at a few autometer gauges at the moment,oil temp and pressure in the middle and boost on the a-pillar.The stock one is innacurate as hell so that can go to the tip :p |
||
| Timbo_021 |
Also,got new tint put on on saturday which they fucked up...bubbles in it already..But other than that,put all the urethane bushes on that i could,fixed up the foggies and doing my best to keep the bastard clean.Its either raining and muddy or hot and dusty so cant win..lol | ||
| Slade |
Show us a photo of the blinged up engine bay and the foggies. | ||
| Timbo_021 |
http://s25.photobucket.com/albums/c91/Timbo_021/
Theres a crapload of photos there i took,have a browse through if u want.I have to take the more recent pictures,gimme a day or so and ill put them up. |
