GT4 Zed

I guess the only question remaining then is can these spacers make any of the cylinders run lean? Surely if all cylinders are getting equal (enough) air flow, and the various sensors are working correctly, the ECU will set the AF ratio correctly and you shouldnt get any cylinders running lean?

 

depends on the level of mods to the car

 

by the time you fit an exhaust, cats/test pipes, spacer, intake, etc it really is time for a tune, as the car can certainly run rich

Spot on as always Adrian

hey am back. was but managed a good one after 3 takes

67, 65 and 72 mind you my limiter is set for 7.5K yep i love revs

I thought you were joking

 

So you got 72 when bouncing off the redline i suppose?

 

What engine do you have?

 

edit: I just read MrLizard has the Rev up engine so thats okay.

i have the rev up GT4 stock engine

i have been busy trying to get info on the Zed and found the following of interest:

first;

Gear 6spd MT 5spd Auto

1st 3.794 3.540

2nd 2.324 2.264

3rd 1.624 1.471

4th 1.271 1.000

5th 1.000 0.0834

6th .794 ----

Reverse 3.446 2.370

Final Drive 3.538 3.357

Secondly using the above ratio from nissan and the formulae below:

-TireSidewallHeight = 2*(TireWidth/25.4)*AspectRatio/100

-TireDiameter = TireSidewallHeight+WheelDiameter

-MilesPerHour = RPM*TireDiameter*PI*60/(GearRatio*63360)

And assuming rear tire size 245/45/18 the theoritical corresponding speeds will be:

gear redline @ 7500 redline @ 7000

1st 44mph 41mph

2nd 72mph 68mph

3rd 104mph 97mph

4th 132mph 124mph

5th 168mph 157mph

6th 212mph 198mph

Abviously if frictional loses are factored in aerodynamic drag, the limiter etc real life figures are less than above stated especially in the higher speeds/rpms.

hope this puts our minds at ease That said i do see 65-70+ all the time and i can surmise that your rev limit is at 6500 as from factory and you are running 19" wheels which puts you about 63-66 mph in 2nd

fantastic job fella!

what was the damage?

or rather what would i expect for my Zed to have similar TLC?!

i'll let you know ASAP if i can't hook up a launch properly. too wet these days and so much wheel spin:lol::lol:

i am a junior cardiothoracic surgeon. i spend most of my time cracking chests open for heart bypass or lung surgery i don't know why i do it because it leaves me so little time to play with my Zed or anything else

clean specimen

welcome to the club

Hey nurrish me thinks we could do this! you supply the expertise and i will be happy to put in start up cash and advertisement

what do you say 70:30 split on markup hihihihihihihihi!

No seriously we would talk about this on friday

A note to take with these though, i member bigphil telling me these can and do fade, sometimes and look a bit dull, hence why i went for the tommy k badge, just a bit of advice !

you are right m8. i think Envy discontinued their supply due to fading issues however i got the black pearl on ebay from Assad (worcester based) who is a member here and they just fine sofar 2 months on

Con-Grats Bud on your buy, missed out

Thanks m8

was that you at 340. you scared me s...less

i will convince nurrish to start making these for the forum and beyond once i see him this weekend

I know its not meant to but increasing the capicity of the plenum increases air supply/flow to all cylinders. im going to run the car for a while and check the plugs again, then if there normal or white should determine whether the plenum is causing the problem or not.

 

It doesn't increase the flow, it evens the flow out. You get the same total air going through, just more equitably delivered.

And if my logic serves right, if its providing more flow to the front 2 cylinders, then the rear ones will be getting less air, and will be running richer.

I don't think so. i do agree with Toon chris though. There is equitable flow to all cylinders after plenum spacing so all cylinders will be optimised.

There is a net increase flow in the first two cylinders and therefore a small increase in overall flow which is dictated by intake and exhaust expulsion restrictions/temperatures.

Moreso the ECU will compensate for the improve flow and run an appropriate mix.

i think we need to objectively determine if the rear banks are running lean at all and identify/correct the problem rather than anecdotal evidence

For the general interest of anyone contemplating plenum upgrading i have added this link for comparisons.

Hi everyone!

 

Just found this Forum...looks great

 

Had my JDM blade coupe for 10 months now, i have considered selling her and reverting back to a BMW but i just cant do it! The most exciting car i have owned!

 

Anyway, just wanted to say hi, i am in Bromley, Kent. I may even be able to attend the Brands meet tomorrow night...

 

Pics coming soon!

Hello & welcome bud,

I don't blame you for the dilemma

I have been there myself. Had an E46 alpina B3 cabrio and E46 M3 coupe back to back before the first Zed. both very nice cars but it is a very different buzz with the Zed.

Stick with the Zed

Hello everyone,

Just drumming up some interest before i put it on Fleabay.

I had this unit on my blade silver 350z GT which i sold last year for my Kuro GT4

Had it removed the GT only to find out the GT4 had Tracker monitor fitted

I was going to keep it and use it on my next car (usually swap every year ) but i know i will keep the Zed for longer

It is now boxed and ready to go with all documentation if anyone is interested.

The main plus points are

1- rebate on your insurance premium

2- peace of mind especially in Europe

2- the subscription is valid till October 2009 transferable!( subscriptions are £132 a year currently)

Professional fitting for the Zed cost £60 at my local (<2hrs labour) but could be more for other cars.

This is what RAC trackstar has to say about the unit:

Trackstar Plus is an insurance approved Thatcham Q rated vehicle Tracker with an average recovery time of less than one hour! Trackstar is a monitored GPS Vehicle tracker which means that your vehicle is tracked to street level accuracy as soon as it triggers as stolen.

The Trackstar Plus is one of the few tracker systems which can be removed and refitted if you change cars. Trackstar can be fitted to all modern 12 and 24 volt vehicles. It is also suitable for caravans, a wide range of plant machinery and some trailers.

Price of £399.00 includes delivery, VAT and Nationwide Installation!

plus subscriptions

I want £250 ONO for this and would be prepared for any desirable Zed bits as PX and cash either way

PM for phone details if you have futher querries.

Oi Dave you be me to it!

i am happy it got

i was impressed when i saw it in flesh and it has more capabilities than OEM.

can't wait for it to be installed now thanks Dave

I think if you make these you would have a market without a doubt

Bennett

Tried dental floss after warming the old badges with dryer and it was still a pain....floss kept snapping

Used 12lb fishing line and sooo easy.

soaked the residual old glue with white spirit and it literally desolves the goo leaving the paint unaffected

It is a good idea to gently warm the recipient areas before apply the new embles/badges

i've seen them in flesh and they look .

BTW nurrish thanks for letting me see the nav setup

Know this is a month old but do you happen to still have the BT?

?New ?Used

Cheers

Welcome

Let me guess......you would be looking for an azure coupe with nismo body kit right!

Welcome

Eitherway i am very interested

Just the motivation needed to pay a visit to my sis in S.ockendon

i keep my eyes open for a consensus

+1

could do with a chrome lip on your wheels IMO. Looks good though

 

Better to leave them without the lip. Theres not enough dish to pull it off & all black keeps it looking stealth

That's what i thought Ian

P15ULT: you have pm

Only seen this stunning shoot now.

maybe azure is THE color after all

nice one Stew and everyone involved with this
