Mods advice for newbie on 07 GT
 

Hi folks, been enjoying reading the forums. Can't understand much of what's written (noobies) but picking up more every day. Hope we get to meet some of you soon?

Have had the (stock) 07GT for a few weeks now and really love the feel and look of the vehicle inside and out but rather 'underwhelmed' by the performance side of things. That's ok as we always planned to save up and do some mods such as an exhaust and proper tune but that's where our technical knowledge ends. Can the folks on here advise approx how much an exhaust and tune would be and what you would recommend the next few mods should be assuming you agree exhaust and tune would be first? Thanks in advance.

Anywhere between $2-4k for TBE/tune depending on where you go.

Cheers.

Wow, awesome looking car but then again I'm a little biased. So given that I can't do all that at once, what order should I go about it in?

There are a few ways that you could go about modifying the car, for example...
[LIST][*]wider lightweight rims, better rubber[*]coilovers, aftermarket struts/springs[*]upgraded pads, rotors, calipers[*]tmic, fuel pump, exhaust, bcs, tune[/LIST]
Have a look at some of the workshops in this [URL="http://www.perth-wrx.com/vb/mechanicals/6775-perth-workshops.html"]thread[/URL] and have a chat with them.
They would have knowledge on what would be the best way to achieve the outcome you would like.

I'm still on the stock exhaust/engine, but have done mods elsewhere and increased the performance of the car (well at least it feels like I have ;)).

Happy modding :D

Cheers Soksta. W have been talking to one of those shops but being such a noobie I can't help being worried. The shop that we want to work with has a good rep so should be fine there. Should probably have been more specific but we are interested in getting your recommendations on what to do engine performance-wise along with exhaust and tune. We might be able to stretch the budget for another one or two things depending on cost but we have no idea what should come after an exhaust and tune on a liberty GT. Basically I just want it to have more power because its kinda lame right now. Even Camrys and the like hold steady with us :(

Quite a few people here have started off with just a new exhaust system, boost control solenoid, maybe a fuel pump (can be cheap insurance) and get a tune.
Depending on what top mount you have, it might be an idea to look around at upgrading.

I would say $2k would be a healthy estimate of what would be needed to meet you requirements, or perhaps just over.

$2K for all of that? I was told the exhaust alone would be over that amount and with a tune it was going to be around 4K. Can you explain what a boost cs is and does?

$2k plus for a Norm Butler TBE ...

Would start at $2k at least.
It depends on where you get your parts from, if you source them yourself and get the workshop to install them, you would save some money that can be spent else where.

Tuning and labour is where I would expect a fair bit of the price to come from.

Some information on the bcs can be found [URL="http://en.wikipedia.org/wiki/Boost_controller"]here[/URL].

If you want to have a look at sourcing your own parts, you can look at this [URL="http://www.perth-wrx.com/vb/general-subaru-discussion/51749-wrx-part-vendors.html"]thread[/URL].

Thanks for info so far. Def not going to be sourcing own parts or doing any work ourselves. Keep hearing about Norm Butler, does he work from a performance shop? Why is his exhausts better than others?

Butler Built exhausts are top quality but as a result are more expensive than others. I was quoted $1995 for a custom designed exhaust for my 06 WRX just to give you an idea on costs. I sourced my own cat back exhaust from Wolf Racing Products and had it fitted for under $100. Will do the same when I buy the down pipe. I highly recommend them (they are a vendor on here too) Free shipping and great prices, plus if they don't have the product you want he (Rhys) will try to get for you.

Norm is not set up for retail sales. It is possible to deal directly if you get him on a good day but he prefers you deal with a shop that retails his products so he doesn't have to deal directly with the public. Doesn't usually cost any more to do that. Most of the workshops mentioned on the 'workshops' page have access to his products and can offer you advice on what suits best. etc.

I own a Liberty GT-B (wagon) MY08 and have a Butler exhaust on it. It is quite loud, may not be everyone's cup of tea.

Other mods on mine are King -25mm springs on the original Bilstein shocks.
That may not be a viable option on yours if it's not a spec 'B' ?
If yours is only a GT spec, I have a spare set of Bilsteins I could sell you to upgrade it.

Mine also has STi Brembo brake upgrade, STi strut brace, STi front lip, EcuTek tune, Prodrive wheels. I can't remember the exact dyno number but I recall it ran a low 13 second 1/4 years ago when I first did it.

dtrally thanks a bunch for your info. I'm really interested to know what you thought of the power upgrade. I think I will be going down a similar path. I can't afford suspension/brake mods just yet and the lack of power really irks me.

My motivation for the retune was to sharpen the electronic throttle response. The delay shit me no end. The brakes was purely to look the goods, I have no intention of ever racing this wagon and the stock brakes were more than adequate.

The power increase was adequate. I have no need for bigger turbo/intercooler/injectors or anything like that on this car. I enjoy that it's 100% usable and reliable. Still goes really well, looks good, sounds good.

The power increase was adequate. [/QUOTE]

About how much of an increase did you feel? Any idea of percentage and was it really noticeable/worthwhile?

[URL="http://www.perth-wrx.com/vb/741649-post505.html"]2008 liberty GT Spec B[/URL]

Top graph is new billet TD05-18G turbo, TMIC and associated minor mods & tune. Lower graph is original VF4x series turbo and Subaru tune (thin line) and same turbo retuned (thick line).

All of the above tunes have high quality 3" dump pipe ceramic coated onto OEM cat back. Add approx 5% on figures above assuming full 3" turbo back.

Best mods are suspension first. Sways, decent springs. Strut bar top n lower control arm. Learn to drive it with some power. Short shifter makes things easier.

Then start on the "how long is a piece of string" power quest ... The above runs 13.7 but I'm sure if Dougie was driving (he launches cars better) it be <13.5 seconds on the 1/4.

GTB that is fantastic! Certainly plan to follow a similar path.

[/QUOTE]About how much of an increase did you feel? Any idea of percentage and was it really noticeable/worthwhile?[/QUOTE]

I would describe the difference as the jolt you feel between (I) mode to (S) mode to (S#) mode then one more on top. In other words, I mode stayed the same, S and S# both took a step up.

So, yes. noticeable.

Hi guys, just wondering if someone can tell me whether or not I-drive is still fully functional after a tune & also will I need a tune if I only put a cat back system on?
Car in question is a 2007 STI Liberty.

Cheers!

@GTB Liberty I'd love to know more about your Lib, what you have done, where you got it done, thoughts etc. Can you answer the above question? I'm keen to know the answer too and judging by your car you've been down this path already.

A cat-back exhaust will not adversely affect the tune. All the restriction is at the first join on the back of the turbo.

i mode is fully functional after a tune if you use a reputable tuner.
