Mods to a GTST

[Milo]

Ok i got a 94 GTS25T.

I wanna start doing it up a bit (its standard).

I thought about doing up the stereo first but that sorta stuff aint my bag. So what can i do without doing heavy work. I e no change of turbo/motor/etc etc.

What i am probably looking for are ideas for cold air intakes and other stuff I dont know about? Any ideas?

TA

[Soulja]

Air-filter (Air-Pod)

Exhuast

aftermark intercooler

Aftermark Chip (always a good idea 2 do first)

[rs73]

Regarding aftermarket ECU, which one more worth it, PowerFC + optional boost control kit or PowerFC + separate elec boost control like AVC-R?

The price difference could be up to $300-400 which can be put into other mods. This is to consider that I don't fancy going to drag racing, so application is for normal street driving.

[Col-GTSX]

Yeah loads of stuff to do.....

I went in the deep end and have personally blown 3 motors...

Do it right.... Get the safty stuff first....

1. Fire ext

2. Fire Blanket

3. Water to put on a fire

Just kidding

Serious

1. FMIC

2. Exhaust

3. POD

4. Chip

Then go stupid.....

If you get these bits first then you will be able to do almost anything and still be safe... well i mean the engine will be safe...

[Col-GTSX]

Now when i say the engine will be safe i mean .....

If you treat it with respect no like i have done in the past....

Learn from my mistakes.

1. Dont put on big turbos on stock coolers

2. When someting goes wrong with the motor and you are still not sure after 24hours... Then buy a front cut... It will be cheaper trust me... ($800 AFM, $2400 gearbox/clutch, $2600 new motor)

In limited knowledge i'd be doing:

* Full 3" Exhaust (front/dump/cat/cat-back/muffler)

* Pod Filter (with cold air feed)

* FMIC (keep things running cool)

* Pineapples (better rear end squat)

* Quality set of tyres (no point having power if u cant put it to the ground)

* 2 stage boost controller

* Ex Cam Gear

Should be 165+ rwkw from that and will give you a nice kick in the pants for a month or 2.

They both contain mods that cost very little and will keep the car driving smoothly and with excellent response.

Pods are a waste of money unless you like the loud noises they make. Just buy a K&N panel element and stick it in the stock airbox. Air filters provide very little performance gains by the way so keep it cheap.

Avoid the aftermarket intercooler if you are keeping the stock turbo, they cost alot. Bottom line is too much cost for very little gain.

1 out of 4 suggestions being correct isn't bad for someone who doesn't own a skyline

[Soulja]

thanks rev210 i try but it also depends of which way u look at it

Air-Filter is always a cheap mod

Exhuast It always help, no point running a mod car on stock one :uh-huh:

Aftermarket Chip = good idea

Aftermark intercooler (i like the look of a front one )

By the way rev210 might be getting myself a R_34 GTS-T 2 go wit the vette

[rob77]

Its quite hard to chip an r33, the chip that stores the maps is also the microprocessor for the ecu. My suggestion's would be:

full turbo back exhaust

bleed valve set to around 10-12psi

powerfc or wolf3d ecu

That would have you up and around 250-270hp, depending on the dyno which would make for an entertaining ride. A bonus of the wolf3d over the powerfc is that it has boost control built in, so you can do it more reliably than the bleed valve.

[Guest MFX_R33]

Yes Rob is right. It is very hard to chip an RB25, but if you are only looking at mid mods, you don't "need" to go to the expense of a full aftermarket ECU. A SAFC would do you for mild mods (and a shit load cheaper). I would also recommend just getting a very cheap bleed valve for the boost control which does the job without a problem. You can go for a "Turbosmart" unit or alike (around $100), or just go down to you local auto parts store and you can buy youself a T-Piece some hose and a ball valve (about $20) which does the same thing. I have even gone further putting in a 2 stage, fully adjustable boost control using a fuel solonoid (cost me around $70).

Milo, I'm pretty much in the same boat as you, I've had my R33 a couple of months and am contemplating mods.

If I was you i'd look at getting a 3" exhaust/hiflow cat/dump, air pod+partition wall, dual stage boost controller, FMIC (not to big) and an APEXi S-AFC II or full blown chip like a powerfc if you have the cash.

Susupension and handling wise, maybe some front and rear strut bars, pineapples and adjustable suspension.

[king_kw13]

Like Milo I am a noob. Few qs

If u wind the boost to around 10-12psi, would it be safer to get a FMIC? Or would getting a cheaper intercooler like a GTR one be a better bet?

with mild mods would getting an e-manage be sufficient? Or would the power fc be a better bet (cos once u feel the boost, u wanna mod more and more)

Great post keep the suggestions coming

[benm]

No point getting any type of management system until you have done all the basics:

Full 3" Exhaust

Pod

FMIC

Boost Controller

= ~$3000

Otherwise you'll spend just as much getting your PowerFC (~$1500 + Tuning) re-tuned after each mod as you did buying the PowerFC.

Besides some cars dont require any management systems to get good power especially in the early stages. If your talking in rwkw (which is the only measurement i sorta understand) then...

Stock Exhaust -> Full Turbo-back 3" Exhaust = ~15rwkw

7psi -> 12psi = ~15rwkw

Pod filter = ~5rwkw

[BOOSTD]

I would definately be getting a front mount intercooler and bigger fuel pump, if you want to keep ur engine from detenating. Which should be no 1. My intakes temp dropped from over 40 degrees above ambient to a max of 6 degrees above. Pwr increased by 20rwkw with no extra boost. My pinging levels dropped by half when I installed the Bosch Motorsport pump, which can be put down to more stable fuel pressures. I can't stress these two mods enough.

[rob77]

we have a car running a stock intercooler with a powerfc making 260+ hp on a dyno dynamics with no detonation. from a budget point of view the fmic is a myth unless you intend on changing the turbo or want to do track work.

[Guest MFX_R33]

I have got a reliable 205rwkw with the standard fuel pump, and no sign of detonation. But I think I have just been lucky on the fuel supply side.

[king_kw13]

Lots if differing opinions definitely.

- FMIC sounds like it is not worth it for mild mods. But isnt it worth it if u get such a good drop in intake temps? Will u get temperature problems if u run a GTST on higher boost on hot days?

- Can u really get ~5rwkw just by putting a CAI + Pod filter on??

- Does upgrading a fuel pump mean u need to get a SAFC or get a management system for it?

BoostD - r u running any other mods to require the fuel pump? Turbos?

[BOOSTD]

fuel pump requires no mods as fuel pressure remains the same.

[95GTST]

My 2 cents; I too am new to Skylines, and am currenlty contemplating mods. Full turbo-back exhaust, Apexi S-AFC II, FMIC and fuel pump will be my first mods. You really can't go past the FMIC! Pods are a waste of money (my opinion), and remember you're only allowed 1 intake mod, or else the boys in blue will give you a nice piece of paper:)
