Did you check your sparkplug Wires.. sometimes hot or cold they will ground out. Sometimes you cant even see it on the outside of the rubber. Easy way take a spray bottle with Water and spray while car is running this wil also find shorts in engine bay =-).. just a thought sometimes its the simple things

Uhm do the N/A 300zx ECU Swap or Maxima ECU same stuff someone on the S130 Posted how to do it on N/A I did it on my Turbo So far so good other than I need the Damn different O2 for my 1987 300zxt ECU lol but thats no biggie! on the good run I did have the friggin car flew!! till I fouled plugs cause im running PIG RICH without that O2!! lol but for people who say it makes no difference.. pfft They need to try it first..
-
Well thats why they were there I mean its all Metric so the guy was like "Fug this Crap" and tossed it down there lol
-
yeah from what I see the Center B wire goes to 24 Pin and looks to be a ground shares other commons along way to Pin 24. Yellow wire goes to Pin 115 and G/W I think it says connects not only to Air regulator Power but Pin 34 So I Imagine I would just wire it like this..
Black (middle wire) to pin 24
Yellow (right wire) to pin 115
G/W (left wire) to pin 34
and I should be good..

Hey for your "was there a system that used a smaller turbo to spin a bigger" Yes I believe so. When I was building up my 1992 Eagle Talon TSi there was an article in one of the Tuner Mags that showed umm *looks through mags* ah here it is AMS was building a 4G63 obviously hvy mod'd but it had a built Sequential turbo system that used a smaller turbo to obviously speed up the larger. Without the small turbo the engine produced just over 1000HP but it was for a build competition so they didnt have time to really get all the specs in for the smaller turbo but they have a Mounted pic of it it Modified Mag where they won the overall challenge and beat out all the Nissan Engines and Hot rodder ones. So yeah they are out there for Gasoline. This one ran 35psi on the larger turbo alone.
Also! Didnt an older 280zxt used by some racer use TT on a L6 cause I see you can buy Manifolds for the TT version of a L6 still

<-- (engine front) E II E I EE I E II E
Put wrench on Crank pulley bolt. Turn till #1 cylinder valves closed.
Cam lobes will be pointing up when closed.
#1: Adjust only 1,3,7,8,9, and 11
using feeler guage measure the clearence between the cam lobe and the valve rocker. Valve clearance should be (hot) intake--(3,8,11) 0.010in or 0.25mm), exhaust --(1,7,9) 0.012 (0.30mm)
If its not to spec loosen locking nut and turn pivot nut till the guage starts to move and its slightly crimped. By that I mean like not binded in so you cant get it out lol.
#2: turn crankshaft again so #1 lobe points down. and adjust 2,4,5,6,10 and 12. As you did with first set of valves.
#3: reinstall Cover and boom start her up!
err then check your compression again...
-
Valves arent bad to set up at all. two nuts start at front work your way back crank a it do the next. I can send the specific way to do it if you want. dosent take much time valve cover off easy liek 5 mins set TDC and go! TDC just turn crank by hand well socket on crank and a nice long breaker bar =-)
what is it again like .035 or somethign guys? I'll look send me a PM if you need info
-
I was thinking that only cause when like you gas it and it actually gets to good RPM obviously the plugs are hotter and shedding some of that newly formed buildup you knwo and then when they cool down again they arent fireing proper cause its building up again. So yeah I'll get that O2 anyway but also do you know anything about how you would Wire up the 3 pin O2.. I think I posted wiring diags on my Album of 300zxt but from what I can see it looks liek they just get looped into the black wire near ecu but before any pins?
-
So the fuel pump is one when the car is off? Dose your Battery Die. Its not the Power attenna trying to go up or down? Get a NEW ONE ANYWAY!!! newer is better
-
Looks pretty nice, nice big turbo. pretty kewl Mod
-
hey might seem dumb but how'd you get your pics on this page I tried just shows a damn X!! lol

OK so trying to mess with TPS I get great throttle responce now. Everythign I expected maybe could have 5% more juice but this happens.. When I come to a stop say a red light. I go to drive again and its liek putputputputput and blows a bit of black smoke out back liek totally unburnt fuel for about 8 seconds then starts to go but cough and sputters the whole way about a block then starts to drive normal again.. Whats happening..
like how dose that happen after 5 mins of perfect stop and go.. is it because I unhook O2, or am I not getting enough Air? if so why? Also If I turn it off and then back on its liek that never happened lol
I have pics of my entire Setup on my album.
heres a list of converted parts.
1987 Turbo 300zxt ECU
1987 Turbo 300zxt
1986 TPS 300zx N/A
1985 VG30 MAF (6 pin ABCDEF all hooked up proper)
1991 60mm Throttle Body (bored intake to 65mm totally sealed to TB)
1982 Turbo 280zxt intake Manifold (ported to gasket to head & head port 32.5mm)
1987 DIZZY
1982 Stock Downpipe with stock O2 sensor in (tried disconnecting and connecting same issue happens)
Again I followed Afshins post to the T so from my knowledge im running extremely rich obviously causing the "Bog" effect right? which would be that black puffs coming from exhaust.
If I wide open it after a couple seconds I get my throttle back but it still coughs and sputters sooo is it just the TPS not exactly where it needs to be or whats my next course of action.
I know that I need the different O2 sensor Bernarrd said I could run without which is fine either way I trust the word of Bernarrd sooo if he sees this what do you think man!
also should I rotate the Distrubutor cap am I firing to late?
Only other thing I can think of is when I disconnected the Injector pigtails I misplaced where they go but on wiring Diagram it says :
#1: is Green with White strip
then 2 and 3 and green with black strips
then 456 are the green with yellow stripes. so possibly ones not in the right order? I have 1 on 1 and the two black strips in 2 and 3 and the yellows on the 456. now will it matter where they are if 456 are all yellow? will I have to trace it back to ECU (GAWD PLEASE NO!!)
Cause I idle just fine so not sure whats up.. Cause if injectors were on in wrong spot wouldnt it not idle properly
Any info or things to do next let me know
Also as I should should I turn the Distributor I'm thinking Buy a timing light tomorrow LOL advice please cause as I said I got awesome responce huge gogo for like 5-10 mins then all of a sudden its liek piiiig rich

yeah I mean the hoses should hold it there no prob less your rally caring or something

eww... took a grouses (small chicken like wild bird) head off with that same car going to the parents cabin left a small triangular dent in the body kit lol...

The above post or. Take off wheel so you have a bit more room support engine with a jack underneith or a long Metal bar with a chain around engine. move the brake and fuel lines away from frame take a Grinder wheel with a couple discs. Cut it out completely so it never rust again and take some good thick sheet metal cut a similar have U and tack weld it on or if you have no welder place U piece there and take SHeet metal Bolts and run em through (pilot hole with a drill bit first but smaller of course so sheet metal screws hold) then cover with fiberglass then anti rust then paint then ROCKGUARD!! hehe
-
I have mine kicking around cause I just swapped to MAF 300zxt ECU but you'll have to pay shipping from Canada hehe
-
Oh this could turn into what you found in your car....
So My first Z my 1981 280zx N/A in the back driver fender inbetween the panels I noticed rust forming. When I cut it open I found a Tshirt with Japanese writing!!!. I figure the guy got hot put his shirt down then it was permanently sealed within the two panels!! Causing rust... hey I should give that to Nissan and say hey you owe me a New CAR!!!!
-
theres a Post I think on here or Zdriver that shows a Bracket that can be made even a Machinist can make the bracket and it works. I have one sitting my my backyard 1991 z32tt but am going to use my stock n/a 225mm 5 speed 280zx one. for Now! hehe. Look around you can find one
-
Well that AFM dosent look liek stock for one but yeah theres a Retainer that goes over that that is supposed to have 3 holes in AFM for three small bolts that hold it to that part you have in Pic one.

ok kewl ty again very much. I got the other TPS today off a 300zx n/a that was in the junkyard with one connector so hooked that up.. Ran awesome for a bit then kinda sputtered so I figure I should set it again or yeah the timing thing. blowing a bit of black smoke RAW fuel so.... hehe.. more adjustments obviously yes?
-
Awesome TY for Reply.
Weird thing when I used the other Pigtail that hangs to the side of the tps (300zxtt 1991) I got wicked accelleration but then after about 3 seconds it would go pop and die to idle and do a accell decell accell decell unless you just barely pressed the gas. so Im looking at wiring diag again.. But I think Ill just go grab another TPS off a VG30 tomorrow that dosent have that extra pigtail. easiest bet
again ty much for reply
oh also!
I dont have a timing light as Im waiting to go into schoo now for Mechanics so im not at my shop.. anyway to set it without or should I just leave where it is now? I think it has to be reset to 24btc? for the z31ecu? no?

Listed of changed items:
3" exhaust pipe to 3"in out Magnaflow Exhaust
K&N filter cone
1985 Maxima VG30 MAF (6pin)
300zxtt TPS 1992
60MM Throttle Body (custom cable throttle)
Ported intake on Manifold and Head as well as 60mm port for TB adaption
1987 300zxt Turbo
1987 300zxt ECU
Stock 280zxt O2Sensor (which I hear needs to be replaced for this conversion)
Stock Jpipe for now waiting on intercooler
Stock Turbo 280zxt injectors
stock fuel pump
ok so I set TPS to be 0ohms at closed TB and at about half it dose its infinity thing so if I am correct that means it is working. So if I just use about say 20% throttle its great its got a sweatspot at about 65% to 75% throttle but if I JAM ON IT! I get not much accel it feels the same as 75% throttle if not more laggy. Sounds like tons of air is going in but no GOGO..
Now at 75% throttle I can hit 140kmh and still climbing and at 100% it still accelerates but its not liek it was before using stock ecu.
so What could be the issue?
the 1985 Maxima MAF? is it set for lower air ratio?
is it the 280zxt O2 sensor with 1 wire and it needs the 3 wire 300zxt O2 to read higher TPS and intake readings?
I cant figure it out.
turbo is nice and loud sucking tons of exhaust and pushig tons of air so the turbo isnt screwed from the sounds of it.. there was only minimal shaft play like MINIMAL. soooo not sure whats up. Pics on my album.. maybe you guys can help me out ty I have gotten no replaies in the S130 section for days
-
OK so tested the TPS seems good. at all the way back its 0ohms and as you move it forward it goes to infinate ohms. I beleive thats correct
now.. I did the 300zxecu swap. everything seems fine so Im thinking it might be the MAF is reading to much air? heres what I have so far.
60mm Throttle Body
K&N filter
1985 Maxima MAF from a VG30 non turbo
Customed a Throttle Cable
Idle set at 850-900rpm
Stock turbo injectors
3" straight exhaust pipe to Magnaflow performance Muffler 3"in 3" out
Stock 280zxt O2 sensor (waiting on 300zxt sensor with 3 pins)
no intercooler as of yet its on its way VIA snail Mail
Stock Jpipe
1987 300zxt Turbo *wastegate end* modified to fit stock 280zxt Jpipe (longer bolts)
1987 Turbo 300zxt ECU
wiring done correctly.
Now when I punch it its slow to get up to speed then gradually gets there but its like I hear tons of turbo raming air in but no GOGO..
so could the K&N filter be to close to MAF? its in my photo album I took the filter put it right onto MAF the the Stock pipe to turbo. so Am I getting to much airflow? Not Enough Fuel?
Idles awesome revs in idle awesome. Figured I set TPS right (through its siet to maximum back) but thats how I got it to rev the highest. Now if I go 75% throttle its great smooth accel but 100% and its like stays at 75% boost hits 8psi but nothing liek it was when it was stock ECU280zxt so I figure either the 85MAF maxim cant read turbo'D airflow or hwtas your guys take on it?

If you want I can show you my Cable throttle linkage it was so friggin easy to build. I used the Stock armature at the firewall and just made a loop with Moutainbike Brake Cable and used a Wire crimp to hold loop together then ran "X" amount of inches to the throttle body to which I added a Maxima throttle cable holder thingy lol witha nut and lock washer used the TB springs for tension and vwala throttle cable suppper easy and the test pound of the brake cable was liek 160Pounds which I doubt I'll ever step on the gas with all my weight LOL I just use ankle pressure and its max'd
