Version 9 upgrades n stuff

[optmspotts]

So we can disregard the thread about advice for Version 8 STI because I found myself a tidy as Version 9 etc etc etc GREAT ;D

The car currently is about as stock as it gets, save for a GFB Respons Hybrid Valve.

I\'m definitely going to get this thing tuned at Possum Bourne ASAP and while I\'m at it, I\'m looking at my (dwindling) budget for upgrades to do (pre tune) that require a tune.

I\'ve always had in mind to go turbo back exhaust to squeeze HP and also for dat exhaust sound. However, I don\'t want a car that screams "arrest me" from being too loud or having an aggro muffler protruding from the rear... One option isto put a front pipe (~$300) in and leave the rest of the system stock.. I don\'t know what sort of gains/sound difference this will make. One of the appealing factors about this is keeping the stock look from the outside.

Alternatively, there is the cheap Chinese exhaust system (~$600) or a full Rage exhaust system (~$900).

What would you recommend? Would it be worth putting in a full system, but keeping stock muffler on?

I was thinking about getting a K&N Typhoon short ram intake, but I\'ve pretty much 100% decided against that idea whilst typing this post.....

Also, DEFI boost gauge: anyone know a better/cheaper place to find them than eBay?

Under manifold intake pipe, airbox to under manifold pipe, removal of snorkel, but keep airbox and under bonnet air ducting. Divorced downpipe (front pipe) and a well silenced 3 inch cat back pipe to match the afforementioned front / downpipe. Fuel pump, new spark plugs, new air filter.

Tbh, you are better off getting an open source "stage one" map, and get someone to adjust the tune as you modify it. New swaybars, endlinks, sticky tyres and enjoy driving it before you increase power. As standard it\'s a bloody fast car, get used to it, the power delivery and it\'s cornering quirks before you chase more killerwasps....

I\'m... not familiar with this? Care to explain or provide link? Forgive n3wbie

I\'m assuming this means that a K&N panel filter counts as sufficient? Once again, forgive n3wb ;D

[newsuba]

You found one with the lightweight BBS wheels.

Nice !

agreed above

yea if u wana kep it looking a stockish then a front pipe and under manifold intake and desnorkle the thing keeping the stock box

possibly a walbro and good service and then get it tuned

if u can afford - a nice boost controller for that better top end and spool

pretty much will be a nice street car and easily in the 12\'s at drags

Like one of these? ;D

Also, this whole "under manifold intake" is all news to me, where to I find some sort of guide for this etc? ???

[Pappu1]

thats just a solenoid that replaces the stock unit (does provide better controll through the stock ecu apperently)

yea that would work as the possum ppl can tune the ecu with it in place

i was thinking more like a EBC unit like a stand alone controller like a HKS EVC4 amd also they come with a built in boost gauge so u wont have to isntall seperate

and the under manifold is a silicone unit

look at scarles/STA/luxury sport they have it

u can get the perrin ones from the states for a bit more $$ though

maybe better quality

on stock turbo the lcal ones should do fine tho

I have one of those and they are awesome! The best thing about it over a electronic boost controller is it still gives the ecu the ability to cut boost and run wastegate pressure if it picks up something out of place.

[Kiwi_Fozze]

I\'m looking at getting a 3 port, surely it can run from any stand alone ebc???

Sta parts are awesome, tell them you ade a clubsub member and they\'ll sort you out!!!!

wouldnt the solenoid that comes with the eboost be 3 port already

i dont know why anyone would fork out for an ebc when the factory ecu can do the boost control the same... but whatevs works i guess

above advice is right, free up intake / exhaust, reflash it, go nuts. the muffler is normally the biggest restriction on a suby, but theres plenty around which will open it up without having big volume

personally i reckon lowering it a bit would do wonders for the visuals too, set of springs alone wouldnt cost you too much

Buy my panel filter!

I\'m pretty sure it\'ll fit straight into your factory airbox.

As for mods... downpipe, a fairly subtle exhaust (Rage is LOUD and the chinesey ones are pretty noisy too)

REAR SWAY BAR. Get a 23mm. Hugely decreases the pant-browning tendency to understeer.

Under-manifold intake is a pretty enormous PITA to install and probably minimal gains unless you\'ve done a lot of other mods.

[Kiwi_Fozze]

Sooo true. Under manifold pipe means manifold removal.

[Pappu1]

not all intake needs manifold removal

some slide in with a bir of persuation

i know the scarles one fits in without removing the manifold

[Guest hate-evoz]

my M&H intake one fitted under mani prety well, did not remove inlet manifold on my V7.

[optmspotts]

Oooooooh...

stick with the factory intake, they are actually really good.

That\'s all the encouragement I need to save $400

[newsuba]

Save more money - stick with the factory filter.

Are they less restrictive on later models? The stock on one my V5 looked to be quite skinny in places.

[optmspotts]

Oh dear.. Finally got my internet uncapped and was able to look up videos of STI owners using aftermarket downpipes on the factory exhaust system...

Dont know what you guys think, but they seems pretty raspy (nasty) to me :-\

So now to go about finding a decent turbo-back exhaust arrangement that I won\'t need to sell my kidneys in order to fund . . .

[Scoobydoo]

Go to FortyOne Automotive and see if there\'s any specials on. It\'s a great time to buy from overseas, the Kiwi dollar is very high against both USD and YEN

[BINKZ]

Keep an eye on http://www.subaruspeed.co.nz/ also.

although maybe wont have much for V9 given its alot newer....

just a suggestion

[optmspotts]

Anyone know good exhaust vendors in Auckland and/or how much it would cost to get one made?

Bingo! .... Although I don\'t know whether the turbo on my car is twin- or single-scroll ???
