Modding A Gts-4

[Kozeyekan]

I've been noticing that there are quite a few gts-4's on the forum, and was just wondering what sort of plans people had for them.

I'm particularly interested in what suspension people have tried, and any upgrades they found suprisingly good or bad.

For myself, I'm aiming it as a traction machine, and so I've got on my list:

Better tyres on 18's (Michi pilots)

coil overs (I was looking at tien, but after some reviews have reconsidered, and am now back at square one on what I would like)

bigger brakes (unsure here too. Have heard mixed reactions to changing to GTR rotors and calipers.)

and maybe some minor power mods. (Already have pod, 3' turbo back, adj cam gears)

Anyone have any stories?

get a 4wd controller, look in the for sale section for them so u can choose between rwd and 4wd

get a spark cut rev limiter (bee *R or a gizmo one)

get a remapped ecu or stand alone

get a pineapple kit for the rear (prevent axle tramp if u have any)

get a castor and camber kit (prevent uneven wear and maximize traction under load so the tyres sit flat and dont sag in)

[AWDMAT]

konis and king springs

i had coilovers, now run that setup

they are a matched set built for gtrs

height and dampness adjustment, and much better traction on twistys

i used to bounce coming into corners

now i power al the way through

i havent heard much on these, is there any threads or web pages that has more info on these?>

Would love to find out more.

I have one sitting in my room, never got a chance to fit it though.

Will probably kill ceramic wheel turbos

With the Bee*R spark cut rev limiter, I think you aren't supposed to have a cat in your exhaust system, otherwise it cooks it. Im not 100% sure on this though

same with the gizzmo

or any other ignition cut rev limiter for that matter

[paulr33]

get rid of the ceramic exhaust wheel too before u use it

Why did you recomend the ignition cut system Paul?

It doesn't add performance does it?

I would love to shoot flames though!!!

launching with 1.5bar built up is fun

suspension? -> get this: http://www.skylinesaustralia.com/forums/in...showtopic=87521

sydneykid has the best prices on this stuff your gonna see anywhere...

i have the shocks/springs and camber/castor kit and the handling transforms the car plus as AWDMAT said, you get more traction and a softer ride compared to Tein coilovers

suspension wise... i wreckon gtr suspension with king springs and strut bars is awesome.. .thats what ive got in my gts 4 and it handles like a dream... 235 17inch rims at rears 215 and front... not much traction... power wise... good boost controller, intercooler, exhaust, fuel pump/injectors and u will be rocking it...

Why are you running different width tyres?

You will wear out the clutch packs in the 4wd system...

Also, king springs good for handling? lol

[Interloper]

yep, diff tyres will stuff your transfer case. Has your 4wd dash light come on yet?

[zero'sR32]

4wd light only comes on when i take out fuse for the 4wd system to make it rwd... otherwise it doesnt turn on... wheels are that width thru the rims ive got... rear rims have an extra lip... work equip 17"s

[R31Nismoid]

you should run even tyres, screws with the atessa otherwise

[blind_elk]

Any suspension stuff, simply get GT-R stuff. I'm running Bilsteins and Kings lowered springs, with Whiteline GT-R HD rear swaybar.

The best improvement of all - RB25DET. Torque to burn. Next best thing to a GT-R.

I'm running a GRID daughterboard on my factory ECU, a GTR fuel pump, HKS2530 on 12PSI (using the wastegate actuator... the Apexi EBC stopped working properly, so just removed it), Tanabe GTR shocks and springs, a switch that I tapped into the fusebox (under steering wheel) to control ATTESA on/off, ARC FMIC, blitz pod, Apexi exhaust, cusco swaybars front and back, GTR wheels front and back (mmmm 7.5kg factory wheels).

It did have an oldschool Apexi AFC and EBC in it, but I've taken them out and am in the process of putting a Jaycar DFA and EBC in it to control things.

Goes nice, altho it does need a bit of a tune as its running at around 12 AFR throughout the rev range.

As for the wheels you can run staggered wheels, as long as the rolling diameter (so that's not just the diameter of the wheels, but the diameter at the contact point on the tyre) is the same on both front and back. so technically you can run 8's on the front and 13's on the back, as long as they're the same rolling diameter. However it's less likely to detect a loss in traction and therefore put power to the front if you run a wider wheel at the back... a small difference shouldn't matter. Conversely if you run a wider wheel at the front it'll detect traction loss more easily... tried it with mine, but the novelty value runs out pretty quick
