what the FACK?! i missed your thread dammit haha

but damn that's sick that your swap is done as for the bumper, you should sand it down and use some "bulldog paint adhesive" for plastic surfaces. It makes the paint stick to our urethane bumpers. Just a quickie sand, 2-3 coats of bulldog and some white paint should make it look a ton better for now.

again, congrats on the swap..when i get my 14 back within a few weeks to a month I'll go and check it out

congrats on getting the swap done! i've been saving up for mine. only problem should be labor costs for me... i only know of two people i trust doing it. both very reliable. one wants $2500 for labor and i'm not sure about the other.

how do you work on these motors tho? changing a water pump or an exhaust gasket looks like a b**** and a half

water pump is easy its towards the front changing exhaust gasket would need removal of engine all in all their not that much a pain to work on just a liil more time consuming

and time is money. its not that bad if you do things yourself but if you're not mechanically inclined the car is a b**** and parts are expensive even if you do know how to fix things yourself.

UPDATE: ok so now that the whole "omg i have a tt" excitement is starting to wear off a bit i have a few questions. i want to raise the boost a bit but alex was telling me not to touch anything untill i get a wideband. now does anyone know if there is a wideband and afc combined into one? i'm trying to avoid buying 2 things dedicated to the same task, i dont want just a gauge to tell me what my air fuel ratio is i want something that can tell me what it is and allow me to adjust it. does anyone know if they have somthing like this? also low end torque is a b**** on this car does anyone know how i can improve this? also my throttle response is kind of laggy could this be due to a bad tps? and my idle fluctuates alot it bounces up and down and nearly dies sometimes what is that about?

The Idle jumping and slow response sounds like it could be the TPS, check the unplug her and adjust it to like 500, then plug her back in and she should jump to around 750 or 8, thats what was happening to mine.

as far as I know there isn't anything that is a wideband and a gauge in one. People get a AFC NEO and then use the wideband on the dyno(sticking the sniffer down your pipe) and dyno tune it. The wideband guages are nice cuz you can always monitor your AFR's when you're driving so you have an idea if your engine is gonna blow....if you see AFR's in the 16's on full boost then you know you have to back the f*** up or you're gonna blow something.

mike how much boost are you running?

stock boost, my car is slower than yours for sure if thats what you're wondering. i dont have a boost controller so i cant adjust it and even if i did, i need that afc and wideband before i touch the boost.

stock is what, 7 psi? How does your car compare to louis's car when he was at stock boost?

You have a boost gauge right? How is the spool? check all your intercooler connections, maybe you have a boost leak.

get the boost gauge hooked up and see how it spools. If the car is really laggy and slow it sounds like you have a boost leak

problem is when mines tuned the ecu they put a chip in it and put jb weld over it so whatever they did cant be removed so i'd have to program over that program and i don't know that you can do that. also you cant adjust boost jets can you? and i dont want to run 14 psi all of the time.

lol i hihgly doubt its jb weld ive seen what your talkin about looks like some nasty goop sh*t dont bother f-ing with it if you can find a good core send it in to z1 or ztuner to get programmed for oyur set up, plus if you go wide band you need two bc you have 2 o2's, if your goin to do things right get a good electronic boost controller and ecu tune even if you have boost jets thats not bad for the mean time till your able to afford better upgrades your mines should be tuned for up to 15psi which honestly is the hihgest you prob want to go right now since all we have is 91 octane so boost jets for the mean time is what you should consider

btw erratic idle usually means vaccum leak.. also you should already know stock boost level is 9.5psi so check that on your aftermarket boost gauge

time is money for the ones that dont want to work on their cars, parts arent to bad price wise we dont have honda civic's so nothing is cheap, turbo cars can be alot to maintain especially are's alot of us knew this jumping into the z32 otherwise this is not the car for the 20g a year person.. we have to be realistic about what we can afford sometimes as much as we want the cool car

oh man! i didnt know i'd need 2 wide bands! f***, do i actually need those because i dont want to spend that kind of money twice! isnt it safe to say that both sides will act the same so i can just read off of one side? but yeah i know its not jb weld i'm just saying it looked like it is some wierd s*** but i guess i'll have to have someone chip it or something. but how do i get boost jets i dont understand what those are or how they work....

I don't htink you need two widebands, usually just one works upstream from your o2's. You keep the o2's and put a bung for a wideband

to get an accurate read you need two as far as i know, and if you put an bung upstream for one wideband thats still like running off one bc whats calculating the a/f mix on the other 02?? considering our exhaust are seperated

boost jets are simplehow to:http://s95014253.onlinehome.us/63104/204583.html

where to buy:http://www.z1motorsports.com/p...=3082

or you can go to kragen and get welding tips with .38 orifice or somewhere around that size and stick them in might be cheaper then Z1

if you have upgraded your ecu or have nistune you can run boost jets. I just installed mine. All you have to do it go to a welding supply store and buy welding tips. I used tested .035, .040, .045. with .035 i was doing 17-18 psi (detonation). with .040 i was doing 15-16psi (detonation). with .045 i am doin 14-15psi rarely going to 15 (PERFECT). i would recommend .045. if you have upgraded intercoolers you might be able to get away with .040 but every car is different and every car is setup differently. get a boost gauge so you have an accurate reading. when putting them in spay some pb blaster, wd40, something to lube the hole so they go in easier.

im sure your running 93 octane correct z32twinz? anyways we only have 91 in CA so 15 is tops i would go, you can run 15 with single pop and catback exhaust if you have more then that yippie but still wouldnt boost hihger then 15 bc of our fuel (91) if you get 93 or higher you can do like 18 i beleive since you got 550cc injects, 18 is what i think max you should do on stock turbos and ecu tune matters also, all in all just keep at 15

yes we have 93 octane here in texas. even though he is running 555cc injectors doesn't mean he can boost 18psi. 1 you need upgraded turbos, 2 upgraded intercoolers, and 3 a good tune. the stock turbos get sooo hot when boosting over 15psi that the air explodes in the engine before it even sparks (detonation). i was detonating at 16psi on 93 octane.
