Gti-r turbo on a bluebird Atessa

[Craazy]

you might wanna spend that cash on the fuel system and nistune before doing the turbo...... the turbo will only make matters worse for you........

[S1NN3R]

yeah im not going to put it on straight away..i just dont want to pass up a good deal.will go on the same time as the fuel upgrades and nistune etc.
but yeah $700 sounds pretty good to me. hope it all works out:D

[S1NN3R]

if i was to take the tube that connects to the aftermarket bov,would that disable it? cause i hate the highpitched sound and i dont wnat to take it off as its a pain

[S1NN3R]

?

[Kranzy]

Should be fine as long as you plumb up the hose.

[S1NN3R]

yeah tahts what i was going to do:) also,the lil bit that that hose go's into,should i be blocking that off,would air leak of it if i didnt block that bit off?

[S1NN3R]

i have noticed my car is hesistating at low revs..is this cause of the pod filter? never used to do it..feels a bit rough now lol.
also,when the car is idling,what should my boost gauge be reading? i think its on -25 . i swear it used to be a lil bit more? or maybe im just being paranoid lol. hrrmmm

[lgee]

that is not to bad my mate sold his one like that for $900.00 offer him 6 hundie for it, tell him you have to muck around a bit to get it to fit, gonna cost you a few xtra dollars to get it on.

[S1NN3R]

well it was origanlly being sold for $1000..i dont think i can get it down anymore lol.. im not sure if im going to get it or not just yet..on working a casual job..depends on the shifts:(
time for a new job i think..these turbo cars are expsensive:P:P
since i have had the pod filter on..it seems to be going through even more petrol.. a full tank JUSt got me 300 kms..and that was before the pod was put on lol

[Craazy]

you should be getting 400km's +....... get that fuel system looked at. change your fuel filter, put 2 bottles of injector cleaner through, then a fuel pump and if no difference then fuel reg, if still no go then it needs a tuned computer or possibly new injectors. get it looked at or you'll end up loosing a piston

[S1NN3R]

yeah i think its best i get it checked professionally. just dont know where to take it. i recon i would only just get 200 kms to a full tank atm with the pod on there..rediculous. also smells of petrol after driving it

[Craazy]

try status tuning in dandy, they are getting a good name and they'll do a nistune board for you aswell

[lgee]

yes they are good, i was round there tonight talkin to Kat and Trent, but they dont have a 4wd dyno nor does Dr Drift, they can do ur nistune and make it run better but doing a fine dyno tune they cant do, but they can sure sort your car out.

[S1NN3R]

you'll probably find that the car will drop off in power more frequently now you have a pod on it, with opening up the exhaust and intake the bluey SR20 only really likes the exhaust done, you will need to get the AFR's looked at straight away, then determine fuel pump or fuel reg, and spend the $250 on the Nistune board for your car. more than worth it

Where can i find the nistune board for $250 :O

[Jono]

I just read the last 3 pages of this thread...

Removing/blocking the vacuum line to your BOV will allow it to leak. You need to remove it altogether and block all the pipes and flanges to it. This could cause higher fuel consumption and rough running on boost.

[S1NN3R]

yeah i noticed it ran really shit with the tube off the bov disconnected( i did put a screw in the tube ) so i connected it back straight away:) i just tightened the bov so it doesnt make the noise at low boost..instead it makes a lil bit of a flutter sound:)

[Craazy]

what jono means is you need to remove it completely coz it will leak under any boost without the vacuum line attached to stop it from opening, thats how they work.

i got my nistune stuff from nistune, two boards and software for 500 and its less for just the boards without software, since you probably wont need it just get a board pre-loaded with the U13 maps then just get it tuned by someone like status. really easy and cheap

[S1NN3R]

i just went to drive my car..and it wouldnt start:S i drove it 2 hours earlier and started fine..also made a beeping noise thats its never done before..some sort of immobilser maybe?

[S1NN3R]

have any of you guys had any experience with a IHI pe1420 turbo? what sort of power could it make? i hear its very responsive.hrrmm

[S1NN3R]

ok so this may sound retarded..but i just got a consult cable..where bouts is the consult port on the car? lol

[S1NN3R]

ok well it was easy to find lol..i did a data log of my car if anyone is interested.
not quite sure how to post it up though.its a notepad file..anyways,is it normal for the 02 sensor to go crazy? lol it kept moving up and down..also had a fault code 34..( i think it was that? either way it was knock sensor error)
hrrmm

[Craazy]

yeah the O2 sensor goes crazy at idle, its meant too, and will generally stay stable during normal driving conditions. if it doesnt do that then it is stuffed and could be one of the causes of your problem.

be warned they are hard to find new apart from nissan and they charge an arm and a leg for them.

with the knock sensor issue, this will be why your car will drive like a gutless wonder, 1: the knock sensor if its faulty will put your car into limp home mode (or low octane fuel maps). 2: with the mods you have the car is running lean and causing it to detonate (ping) its ass off and the knock sensor is doing the same as No 1 without being buggered.

turn your boost down to stock, ie. 7 psi, until you either fix the fuelling issue or get the car to a tuner to get it looked at in depth.

it will cost you alot more than just a couple of fiddly parts will if it keeps detonating.

good luck with it mate

[S1NN3R]

yeah i think the knock sensor was from the car pinging. it hasnt been doing that all lately though.. its on 13-14 psi. on the consult software it would say it was running rich when not at full load..then it would say occasionally say lean.

Also here is some of the info from the data log, i didnt know how to attach the notepad document so i just pasted a lil snippet of it

what you guys make of that? looks confusing to me:)
also does anyone have a IHI pe1420 turbo on the bluey or know of anyone that has one? i hear they are super responsive and i can get one for $750 ( wont go on untill fuel is sorted and nistune etc.)
just wondering how much power they would put out..im hoping for over 180 kws at the wheels atleast:)

[Luke]

If you uty cycle is in percent, looks like you might be maxing out your injectors. The other values look like voltages, if they are, also looks like the AFM is maxed, same value all the way. And is 27 degrees of timing maybe a bit much? I don't think my car goes that far, and I have dropped the Compression ratio to 8.0.

[Craazy]

by those figures you have maxed out your AFM and your injectors......

i have seen similar figures from mine when i did some data logging before i fixed the fueling issues.
but still drop your boost down and you will find it wont hit those values when you do data logging again, even try it with a range of different boost settings

[Vithy]

is that normal for someone to be maxing out both the afm and injectors on a stock turbo sr running around double stock boost?

i would of thought it would take a lot more to max out a afm? :S

[Kranzy]

I'm only running 10psi boost and get very close to maxing out the injectors. Afm I can't remeber how close it got but it's very possible. 

[S1NN3R]

i should try it out with the stock air box on there..but i cant be bothered lol..im getting a nistune daughter board and z32 afm soon..aswell as bigger injectors and fuel pump:) its weird cause sometimes the car pulls really hard..then other times it feels very average..im guessing thats to do with the timing aswell?
oh yeah,im guessing the bluebird as a speed limiter or something..and its around 200 right? will the nistune daughter board remove this ? or do i have to get something else,not that i want to go over 200..but its annoying

[Kranzy]

You can remove that in nistune. Aswell as edit rev limiters etc...

[S1NN3R]

mmm not sure if i would change the rev limit..i feel bad enough whenever i rev it out to 7000..which is rare lol...what do most of u guys with the nistune or whatever else have yours set at? would 7500 be safe? cause im thinking of going that largest of the gt2871r. hrrmmm..so many options lol
