well thats a logical explanation...hmmm interesting...

how does more injector latency change the amount of fuel they flow??? i thought latency changes the time the injectors fire in relation to the CAS signal and also spark timing??? if the injectors fire too late then there could be fuel atomising on the back of the valves as they close and waste fuel. with the normal settings for the nismo 555s i can always smell fuel a little around the car..particularly on idle. however with the new settings i smell less fuel...

i know what it should be..thats not hard to find... i am thinking that maybe the nismo 555s are not 555cc?!?!?!? i have found reports of this is a few places around the world... dont really feel like pulling them all out to get tested but i might have too... i think this is the begining of finding something with my car that has never been quite right...

sorry for thre lack on info... RB25DET - nismo 555cc injectors - power fc current setting are 50% correction and +0.40ms latency!!! has never idled so well and runs around 15 AFR on light load and drops nicely as it moves lower on the map... oh and on idle its slightly rich..around 14.2

does anyone know anything about setting up injector lag, beyond just inputing the numbers from the manufacturer? i've been mapping the car but having problems getting a good idle and mpg and the problem seems to be injector lag. i get the car setup ok, it drives ok, afr at idle 14.7 within a few points with no o2 sensor feedback. if i increase the lag a half point eg 0.18ms to 0.24ms my afr's go rich, remap the car and the car drives and idles better. i'm up to +0.28ms so far with the manufacturer saying it should be +0.19ms and the car is a lot better. does anyone know what the professionals do to setup injector lag? i'm thinking what's happening is the injector is being opened too late by the ecu because the setting is too low, thus spraying the back of the valve as it closes. this pool at the back of the valve doesn't burn on this ignition nor on the next, it's just wasted fuel (bad economy). the wideband doesn't pick this up because it cant sense unburnt fuel, spray the sensor with petrol and it doesn't read rich. so, the lag is made greater and the injector fires earlier, this time it gets more atomised fuel ito the chamber for the combustion and my afr's go up, readjust the injector duty and the whole thing is timed a lot better so the car runs better. does this sound ok? i'm wondering if this should be repeated until the lag adjustment causes it to go leaner rather than richer. seems logical to me. any input would be greatfully accepted, unless it's lies

oh yeah and how much for postage to sydney?

do you mind taking a couple of ead shots, like at the each flange please???

hey dude, where are you located?

where r u dude?

yes pics please, i am intertested...

i like that advice...thankyou mr rogue!

well mr rogue thats some impressive economy results! who tuned your car? and what engine managment are you using?

calculators you say...oh my!

ok further information on this for you... the part you have is the worng HPI part, its for an R32. i am pretty sure the R34 dual front pipe is the correct one. i just bought the R33 part from JustJap and its wrong. Does not fit at all, is short and is the wrong angle just like you said...

do you wanna sell any of this gear? mailnly the HPI Split front pipe??? assuming its for an R33 GTST

all i can say is the best kit on the market right now is the new tube and fin GT kit from hybrid. hands down this kit wins in every way posible!!! its around $550, its tube and fin, its very well made, fits perfect and is a lot lighter than the 'china' kits. im not 100% sure where they are made but the quality is leaps ahead of all the other cheap kits. i just put one in my car and was blown away but the quality and spot on fitment. i have nothing to do with hybrid or the guys that sell them... all i am saying is that for $550 you just will not do better and unless you are racing or being sponsored or just have money to waste and burn, then there is no other alternative... ie if you want quality on your car...

Hi guys, i just put one of these kits on my R33 Gtst, was replacing a JJR Bar and Plate kit. all i can say is wow. fits super perfect, better piping, cooler is fantastic, lighter and more efficient. flows much better, had to adjust boost controller as boost was over shooting now!!! for the money these kits are number 1!

ok so some buyers fell through...anyone else?

Hey guys, heading down to wakie tomorrow.... anyone else going by chance?

yeah i agree with you guys in the long run but a genuine greddy is now $1500-$1700... and well i havent seen a second hand on ebay or anywhere for a little while...

probably about to get one next week...

well its definetly the second option... comes on after 1000 rpm and switches off at 4700 rpm or whatever you have set in datalogit...

price please?

also do you loose midrange by going with this plenum??? i have heard that might happen....obviously you gain top end a little. my main purpose of doing this is to just neaten the engine bay and get more response... i love response!

hey guys! top write up by the way. i want to do this for my first big task for 2009. will probably get the kit from Just Jap. i want to keep my plum back BOV...how did anyone do the recirc piping???i will also keep the heating of the throttle body...will do extra piping for that. any other tips? how did you gouys do the piping through the side wall instead of moving the water container???
