83turbo280zx

im in the long and tedious process of cleaning up under the hood of my car, and instead of polishing the stock fuel rail, how can i make a custom one? is there any certain measurements and specifications, or can i just get a fuel rail with 6 fuel outputs to go to the injectors? anyone have pics of their custom rail?

would anyone be willing to e-mail me the factory service manual for the 82zx? ive tried to download it numberous times, and once i unzip it with winzip, every file is @ 0kb, wtf? nothing!! lol anyone wanna e-mail it to me? sk84life1122@sbcglobal.net it would be very helpful!! thanks!!

pretty soon im going to be adjusting the timing on my ignition, and my cam timing as well. what is the best timing for 10psi of boost? soon to boost to 12 when i get an intercooler and better downpipe? any suggestions? btw its an 83 Turbo ZX

ok so here is my current situation, i LOVE my car dont get me wrong, its an 83 turbo zx, and i have nothing but happy moments when im in the car, but there is something definately going on @ low end so i thought i would come here for advice. when im below the boost threshold (under 2300 rpms) my car is deathly slow, my moms mini van has better low end than my car, but once the boost hits im gone. im just wondering what could possibly be causing this? my current guesses are *air flow meter needs to be adjusted *need a new throttle position sensor *need to adjust the timing and valves so this is where i stand right now, ive gone through the basics in the car, plugs, fuel filter, air filter, oil change, cap & rotor, most of the vacuum lines, my gauge shows no vacuum leak, hollow cat, (was clogged) i haven't changed the wires yet, but i seriously doubt that wires would make this big of a difference in my low end power and acceleration, and my egr valve is functioning correctly as well, to my knowledge any ideas?

yes, i know that is how the stock set up is, im trying to put an intercooler in, and would like to place the afm inline with the turbo outlet and throttle body, so im trying to get all the details i can on doing this

ok, as far as my automotive knowledge goes, this should still be ok to route your afm like this, i want to put an intercooler and run the pipes through there the stock airbox was, and in turn put a high flow filter on the turbo, and route the afm inline with the turbo, and the BOV before the afm, so unmetered air escapes rather than metered air like welding a bov to the stock J pipe, see attached diagram for what i mean im sure it will run, but i just want to know all possible pro's and con's and what should i expect, thanks!! btw its an 83 zxt, with the afm on the suction side of the turbo heres the link to the diagram http://www.zcar.com/forums/read/1/1929400

this is probably going to sound like a really stupid question, but i better ask so i dont screw something up, i have no clue what a boost solenoid is, i have a stock 83 zx-t and i have a mbc that i plan on putting on after i adjust my valves correctly, as far as i know, all i need to do is put it inline with the compressor and wastegate actuator, i dont know about removing any boost solenoids or anything, oh and another thing, for the lower nipple on my greddy type s bov, couldn't i T off from that line going from the compressor to the boost controller and put it there, i read somewhere thats what the lower nipple is for, to get a signal for under the diaphram? and you can get it from the line on the turbo compressor or wastegate actuator? please fill me in, lol

to raise the boost before i adjust my valves? or should i do a valve adjust before i raise the boost beyond stock level, i only plan on running 8psi until i can get a better fuel pump, then im going to bump it up to 10psi, but should i re-adjust my valves first? they're ticking pretty bad, to where im running a tad bit rich from idle to about 3k when the turbo kicks in

as far as i know the 2jz and rb26 engines employ the basic same 6 speed getrag transmission, with the only acception of nissan's being AWD, well in that case, is it possible (within a limited budget) to mate an rb26 to a supra getrag tranny into an 83 280zx, or am i better off just putting up with the rb25 5-spd? if its possible, i wanna know because i would love to have a 6-spd behind an rb26

ok sweet, thanks a lot guys, now i read a forum for a 240z turbo, and they suggested getting an adjustable fuel pressure regulator, from my understanding my 83 has a rising rate fpr, so would i need to replace it, or would that fpr be good enough for 10 psi?

hey guys, im raising the boost on my 83 zx-t, how much should i do w/o an intercooler and stock ecu? i hear 10psi is safe on stock injectors and no intercooler, and i do have a greddy type S bov, so i wont have to worry about compressor surge, i also have a 3" full exhaust on the way, what should i do for the pop off valve? should i just take it off and plug it off w/ something from home depot?

hey guys, im looking to replace my boost gauge since im turning up the boost in my 83 zxt and the stock boost gauge doesnt read psi worth a ♥♥♥♥, anyone know what the in dash gauge sizes are so i can make sure and get the closest to correct size boost gauge?

you cant put a BOV after the throttle body on the intake manifold, it defeats the purpose of it being a BOV, the reason a blow off valve is there is to vent the pressurized air elsewhere when your throttle plate closes, if you dont have a BOV inline between ur turbo and throttle body, then the air is gonna bounce right back to your turbo

well the engine has a stock pop off valve, which is not the same thing, the pop off valve is on the back of the intake manifold, close to the egr valve, its only purpose is to keep the engine from over boosting incase say your hose on your wastegate came undone, it would let all the potential pressure from ur turbo get into the engine, and 14 psi is dangerous w/o an intercooler or blow off valve, so it opens to let the excess pressure out. a blow off valve is inline between the throttle body and the air outlet of your turbo, i.e. your intake piping. when the throttle closes, the turbo is still spinning, thus still producing air, when the throttle plate closes that air has nowhere to go, so it rebounds back to the turbo, causing it to slow, or in extreme cases stop or spin backwards, very bad for it, and the more psi you have the more risk you have of damaging your turbo this way, so the blow off valve lets that excess air out so it doesn't damage anything, and keeps your turbo spooled up

oh, well i have a pop off valve and a blow off valve, 2 different things, the pop off valve is on my intake manifold and opens up after a certain amount of boost to keep from overboosting, i'll have to search around and find what i can, thanks for the page about the mbc!!

thanks a lot man!! do you know if i need to do anything with my pop off valve and boost sensor?

well doesn't even have to be home depot, just where ever? lol you know anything?

anyone know what i need to make a boost controller for my 83 turbo 280zx? i wanna push my boost to 10psi and i need to know if anyone knows what i can use from home depot to do it, will i need to do something with my pop off valve? and will i need some kind of boost sensor bypass or adaptor that will trick it so i wont have my fuel cut off? -83 280ZX-T 73K original miles greddy type s BOV, Sony XPlode 1200watts w/ 2 Visonik 12's, NGK Spark Plugs
