Just Ordered My Garrett -9's, What Else Should I Do?

[Booki]

Hey all.

Just ordered a set of Garret -9's + Gasket Kit from Street to Track!

I will be installing them myself, as far as i know of the gasket kit i ordered is only for the turbo's, i take it i need another set for the dumps/exhaust? (Garrett branded gasket set)

Now while i will have everything out and about, do you guys recommend I change anything else to get my desired power out of of 300-350rwkw? (give or take)

Should i change my dumps, intercooler, EBC (the greddy profspec II is $350?) or anything else?

Car specs are as follows;

1995 R33 GTR

HKS Pods

Ganador Exhaust

Hiflow cat

Everything else is standard.

At this stage, I am hoping to get 300-350~rwkw (give or take, ,pref give) but keeping it responsive as the car is my daily driver.

I also believe my car will NEED to be tuned after i have put the turbo's on. Thinking of going the used apexi power fc route. From the reading i have done, its a safe bet to get a tune done at Racepace (im in melbourne, northern suburbs) if anybody knows any more local tuners please let me know.

Any input appreciated on what mods to do while the turbo's are out (And where to purchase the additional gaskets/studs/stuff you guys recommend), or any tips/tricks you guys have found while installing them will be awesome!

You should get a few ideas from these threads.

I myself had -9's on a stock 26, 300 kw at 20 psi.

For up to 280-300WKW most were pushing stock everything, just exhaust highflow metal cat exhaust and tune.

If aiming for over 300WKW, nismo afms, 550cc injectors, maybe a fresh fuel pump, probably get a stock airbox and snorkel setup as it won't suck hot eng bay air.... Also some decent adjustable actuators for the turbo's. 22 or so psi on bp 98 and see how you go

Eng wise, stock cams, but adustable cam gears, stock dumps are fine up to 350RWKW, stock intercooler is fine also. Some sort of catch can setup would help too to stop blowby oil going into turbo intake and intercooler.

[Booki]

Cheers sean, Ill have a read!

When you say we are pushing most of the stock parts, is it safe and reliable to do so?

As the car is my daily, I want to try and avoid things breaking down.

Do brands matter on the adjustable cam gears? Or are they all the same? Just had a quick search on eBay

[paulR32gtr]

I think Kudos motorsport do an installation kit ... might be worth a look. I know the HKS GT-SS (-9s) with its full installation kit was worth every penny at the time.

[paulR32gtr]

Also - I would drop the HKS pod filters and go back to the stock airbox if I were you unless you have proper isolation from the engine bay. Keeps air intake temps lower for longer. Not sure about the R33 GTR ones but also open up the bit in the airbox that draws air from the guard.

Edit: Ahh just read your post Sean - on the money!

[Booki]

Unfortunately I bought the car with the HKS pods on it, no stock airbox was included.

I might have to look at making something up the draw in cold air, otherwise I am not sure if its worth going back to the stock airbox when the $$$ could be put towards other mods?

Is it worth setting up a EBC while everything will be out?

Good to know the stock intercooler and dumps are ok.

Any recommended cam gears? I would assume its best to avoid the pretty cheap looking ones on eBay...can apply that theory to soo many different situations....

[paulR32gtr]

Don't bother with EBC. Speak to Racepace - get the higher pressure actuators and get Racepace to modify them and the wastegates, and put in their boost control setup.

Tomei cam gears, or Racepace can modify your standard ones to be adjustable.

[GTRsean]

As above, with the right actuators you won't need a boost controller.

Stock engine will be fine at 300+ or so at the wheels, as long as you look after it, good tune, serviced properly etc.(and it's in good nick to start off with)

[Hadouken]

yo yo

Good flowing exhaust,

strong clutch because it will slip,

fuel pump,

injectors,

most likely coil packs,

catch can,

No one has said aftermarket computer

There you go

[Booki]

Street to track said the -9 turbo's he is selling me come with actuators, though i am not sure what type.

Question: if i were to go the boost controller route and keep the actuators provided (assuming that is ok), from my understanding i can adjust my boost in the car while driving. Would lowering my boost improve my fuel economy? Or would the car just run stupidly rich due to running less boost? thus pretty much making a boost controller fairly pointless..? Little confused now about running a EBC vs not having one. Btw i am not running any boost gauges, figured the EBC would also serve as one.

So at this stage, i am looking at needing

More gaskets/studs if required

Injectors - ???

fuel pump - which one?

coil packs - yellow jacket, split fires?

catchcan - wow they are expensive, 700 big ones!

aftermarket computer

Tune

Re the tune, does it matter if i put the injectors, fuel pump, coil packs in after the tune?

[GTRsean]

Well I assumed a power fc was what he was planning on getting....

555cc injectors or similar, I got 288RWKW on the stock 440cc injectors and fuel pump and afms.

Stock fuel pump is okay, but how old is it now?? Nismo pump if you can swallow the cost (great thing is that there are a straight fit) or 044.

I'd only change coil packs if it is showning signs of missfiring, splitfires are one of the best besides brand new oem.

Depends on what catchcan you get, eg just jap one is a lot less than 700, nismo oil/air separator kit is exy...

power fc is the most cost effective, but of course there is better $$$$

500-800 for a tune depending on where you go.

RE: Retune,

It will matter with injectors, and maybe pump as it will need a tune again to get the air fuel ratios right again.

If you are handy with a die grinder you can also port match the exhaust manifolds to the turbo exhaust inlets.....

Tune

Re the tune, does it matter if i put the injectors, fuel pump, coil packs in after the tune?

Injectors id1000s they are awesome plus plenty of room to move if you want to go flex fuel/e85

Fuel pump, Nismo worth the money

Coil packs, like Sean said, only if they need replacing, I went spitfires never been happier

Catch can, I went the Nismo set up route, is an awesome bit of kit, race pace do one too

Computer, can go trustee power fc or go vipec

If you want more then 300kw you will need new AFMs either go Z32s or Nismos

Clutch will need to be looked at too

[Hadouken]

If you want more than 300 then just piss off the afm's. I am spewing that I didnt go a MAP based ecu from the start.

ID 1000's like Nick said, are the bomb

You have a lot of choices for fuel pump, Bosch 044, Nismo, Walbro, deutschwerks etc

I recommend Link ecu, as your looking at close to the same amount of money as buying a powerfc and z32 ecu's.

Also look at the just jap autech style catch can. Few guys have run them, love them. Mine is going in tomorrow.

[Booki]

Just to confirm. Its not actually possible to tune the standard ecu is it? I have read about nistune upgrades but they only apply to r32 ecu's.

Is the bosc 040 no good? Thats a direct fitment isn't it?

Will have to see whats involved installing the 044.

I was looking at the SRI Alloy catch can tank, mainly because it looks like installation would be easy, just goes where the washer bottle is.

Although the autech is cheaper, hmmm

[Hadouken]

I feel you have much to learn. You need to do some serious reading.

044 drops in, Im running it and she's fine. Once again, gives room to breath.

No the ecu cannot be tuned. Yes you can get a 32 ecu and one pin needs to be rewired due some temp sensor difference and then you can get that new 32 ecu nistuned

[Piggaz]

I recommend Link ecu, as your looking at close to the same amount of money as buying a powerfc and z32 ecu's.

AND without the headache of re plugging this and that.

[Booki]

I thought the 044 needs modifications to the stock cradle to fit in the tank? There is a diy On the forum was reading it before....

And your not wrong, I've got a bucket load more reading ahead on top of everything I have already read. Just never ends! Expect more Noob questions to follow...!!

My friend before you do anything, the best advice i can give you is, keep your gtr stock - so you can drive it around and your not car-less, and save up and stock up all the parts whilst reading and researching along the way.

Alot of the fellas have given really good advice

[KiwiRS4T]

You can't turn your boost down below what the actuators are set at but you don't need to - you can keep boost down by moderating your right foot.

Hoping that one week will be plenty of time to get stuff organised, installed and setup !
