    R33 Gts-t Auto Vs Manual

    in Forced Induction Performance

    Posted

    i love this thread when i want a bit of fun i put the switch into power mode and drive the auto like a manual have left many a manual sitting at the lights doing this

    Thats cause most people cannot launch...i'd like to see an std auto beat a std manual off the lights if the manual car has a good driver...i highly doubt the auto would have a chance

    Ok i think i may have gotten wrong iridiums originally & when i re-gapped i think i might have damaged the tips so i have a new set on the way which are already 0.8mm & i also have a new NTK o2 sensor on the way as it prob has never been changed (Thanks Kudos Motorsport) so will throw in new sensor & plugs when i receive & hopefully problem is solved....

    if not i wont know what the hell it as i would have changed coilpacks, plugs, o2 sensor & would only really leave AFM or CAS in the equation

    try changing the plugs to a set of copper ones (bcpr6es) and see if that makes a difference (they are only about $4 a plug, so won't break the bank). it also depends on if the o2 sensor was even changed when it was supposed to.

    try disconnecting it and see if alters your fuel economy.

    cheers

    what gap? the std 1.05mm or gap down to 0.8mm?

    not if it was stuffed when you got the car. the hotter plugs you were running got to their self clean temp easier so they could burn the extra fuel easier.

    and how many kms old are the plugs? not age sorry.

    pull them out and have a look and have a look and see if they are fouled up (all black and sooty). if they are then it is running rich and it would be worth testing your o2 sensor.

    ahh i see & does make sense

    plugs done about 2000-3000k max

    I heard o2 sensor should be changed at 60,000 anyhow? that true? if so im due for one as i just have passed 70,000

    regardless i should change plugs yea?

    THANKS

    you have said that they are 0.8mm gap but how old are the plugs? and what sort are they?

    NGK Iridiums & they are only 3months old

    you shouldn't have to run the smaller gap with splitfires.

    thats what i though hence why i am stumped

    i would also suggest not running too much boost with the stock exhaust. it is a bit restrictive and will keep more heat in the turbo.

    yea thats why im at 8.5psi & not 10-12psi

    the reason why it goes away if you fang it is that the plugs are fouling. your o2 sensor may be a bit stuffed and causing you to run rich at low load which is fouling the plugs. then when you fang it the plugs are cleaning themselves.

    but i get my usual km out of a tank? if o2 sensor was stuffed wouldn't that affect my kms per tank?

    Ok here is the story & YES i have read all the threads i could find on topic

    I have a 97 s2 Gts-T

    Mods are:

    8.5psi (Turbotech)

    R34SMIC

    Pod

    EVERYTHING else including exhaust is std

    When i got car always had a slight pop on idle but never missed through rev range....anyway as i had changed g/box & diff oils, all filters etc since i go car i though id change the plugs as god knows how long they had been in there...got a set of iridiums heat range 6 (originals were 5) & threw them in...straight away it started to hesitate/miss at 4500-5000rpm so i did some research on here & regapped to 0.8mm & it made a hug difference but miss was still there on idle & in cold it would hesitate occasionally but i lived with it...then it started getting worse so i thought time for splitfires

    whacked them in & presto miss gone on idle & no hestitation...but first time i drove it in colder weather at night its back???

    Then I noticed when i give it a good kaning it tends to go away (as it does in the warmer weather) so im starting to think maybe going from a heat range 6 plug from 5 might be the whole problem as it seems when its cold they do not fire properly but when its warmer or after i drive it hard it seems to be fine

    Maybe i should go back to a heat range 5 & my car is not modded enough to benefit from a heat range 6 plug & infact running worse

    Any thoughts as im stumped?

    I've already tried install the set of NEW SPLITFIRE'S but it's not helped :D

    same problem...threw in a set of splitfires sat & prob went away over weekend but now its back but only sometimes & notice worse when cold...i have ngk iridium's heat range 6 gapped at 0.8mm splitfires & running 8.5psi with r34 SMIC & pod...everything else is std...what could it be? afm? o2 sensor? i was thinking maybe try going back to heat range 5 plugs as before i swapped to the iridiums it was fine?

    any thoughts?

    Just pull em out and go down to your local hardware store.

    I'd be highly surprised if they couldnt match you something

    Yea will mostl likey do that...just thought id see if i could get some from Nissan first to save getting wrong ones

    Cheers

    I have a set of splitfires on order for my S2 R33 GTS-T

    I also need/want to get a new set of bolts for these...where can i get a hold of them? Nissan Spares at Blacktown told me they dont have them??? (which i found odd) & suggested boltmaster in Penrith

    Thanks Guys
