how quick is the z31 turbo supossed to spool

mine begins to be + boost if i let it sit at 1500 and wack the throttle by the time i hit 2000 rpm i got 3 psi ????

before i put new head gaskets on i had to hit like 2500 rpm while under a load (as in driving) i would get boost no sooner

now i sit at 1500 and zap i got boost???

did i get a visit from the magical boost fairy????

or was there a bad exaust gasket before???

anybody else have this or is it me and my tuning :naughty:
yeah i dont think so :grinno:
`but if so any body else need a boost fairy visit lol :rofl:
wow smilies :iceslolan
lol never used them before :rolleyes:
ok now im a :loser:

any input would be nice

you said you also changed your exhaust to 3".. that probably helped quite a bit.. any sort of leaky exhaust gasket would probably affect your spool time a bit... but then again, any sort of breathing upgrade helps spool time...

yeah tru true that may be it you dont miss a beat i dint think it would make soo significant of a difference though

then again 3" exaust 3" cone filter all heat wrapped everything really good oil and a nitch of 93 with octasne booster lol still gotta try the xylol trik in small doeses

you should get a filter like mine :D it really does look better than the regular filters... fills out that front area better

i love my stainless steel and in the future im gonna put my oil cooler mounted next to it with chrome screening in front of both opened to the front with molding

what kinda filter you got though?

and what do you mean by stainless steel anyway?

hey delirious wheres the prv valve located at ??

my what? pressure release valve?

sorry i meant PCV?

uhh, on the other side isn't it?

i dont know i was lookin for it but didnt see it is there one one each bank or just one

itsd there in the center of his valve cover goin to his intake right ?
and by stainless steel im talkin like all the 3" cones you see only instead of it being like a cotton mesh its stainless steel, you can actually see through it if you hold it to the light
and id get one of those filters but in the future i wana get the oil cooler mounted there
and you still have your baffle box thingy?
lol i got rid of mine first thing
i want all the response i can get lol
and all that does is try and help hush it up a bit isnt it?
and i see your na i had one of those and its pretty snappy for what it is
i also see your still running mechanicle fan
you know you can free up something like 5 hore off that right?

and for the pcv i got the same as him on one side and a little baby cone filter on the other side but im thinking of switchinmg sides due to im turbo and when boost builds itll blow through instead of suck damn damn damn is that whast happened to go wroung sugar thinmk i should have gotten my head milled during gasket rep[lacement though im gonna go see if it chugs off a load though sounds gret but when i fired it up 1st time smoke poured out the valve cover dontr know if iuts burn off or not hmm ill see this weekend after i run it down the road boy the neibors are gonna love me lol 3" straights loud pipes save lives lol

to answer the PCV valve question of its where-a-bouts...

in reference to delerious's picture above:

there is a thick hose (1" in diameter and about 6 inches long) leading from the valve cover to the upper plenum...it is on the passenger side of the engine bay, right in the middle of the valve cover. if you follow that hose to where it goes into the upper plenum...that hose is your PCV hose and it is connected to your PCV valve.

if you havent replaced it, you should because on the Z31, i read it tends to get gummed up more than your average car. when i changed mine, it was so gummy it was ridiculoous if anything could even move through it.

yeah, i just haven't bothered to get rid of it yet... haven't been able to get out to the muffler shop to pick up some pipe for it... yes it's just an intake resonator... not much point to it really, i don't even know why they put it in stock, especially on cars like ours.

as for the fan, it's more like 10-15hp... also haven't gotten around to that... haven't found a suitable kit that fits in the fan shroud correctly.. it'd be nice to get rid of it but it's not at the top of my priority list right now...

i'll look into replacing that hose i think tho.... is it just the hose or does it screw into something... maybe i could just clean it out with a wire cleaner or something..

yah i found it earlier today and replaced it along with my fuel filter and my air filter so im good now complete tuneup done lol

the pcv screws into the intake and i wouldnt recomend cleaning it unless you remove it and solvent dipp it for like a year then put it in boiling alcohol and then blow it out with air then clean it again with solvent
dobnt really just buy a new one

tast what i did went ad boughta new one only costed like $3.99 so now i gotta do a couple things like chec myMAF or TPS totae care of my stumbling problem i have it narrowed down so im happy
