2007 s-GT impreza Mods

[jackvmaggie]

Hey guys,

 

Really value your input regarding best bang for buck S-GT modifications for more power without compromising significantly on reliability?

 

Cheers

New turbo downpipe and re-tune.

 

A new air intake isn’t a performance mod until you’re pushing higher power with a bigger turbo but you can replace the stock panel filter with reusable higher flow one which will be your best bang for buck.

 

 Catback exhaust is mainly just for sound and not really a restriction near factory power level, so if you’re on a budget you can leave this out - the new downpipe will make your car louder anyway

 

Power wise, that’s all you really need.

 

For better handling you can’t go wrong with a larger sway bar kit, don’t bother with a front strut bar but get a rear if you have the money for one - makes a little bit of a difference.

 

 

just to confuse the situation even more, a tune will cost you around $1000 and is a must for reliability and hp gain from mods which improve air flow through the car so if you’re going to get a tune with a downpipe (the biggest hp gain mod on these cars) then you have to consider if there are any other mods you may want to do which would also require tuning (new air intake for example) so you don’t have to keep retuning and burning money.

Awesome comprehensive response - thank you.

 

Could I grab your recommendation for a tuner in Auckland?

 

Based off my research on ClubSub, I am hearing that Torque Performance is the most reliable/professional but highest spend, Possum is relatively expensive and reliable and autoupgrades is the cheapest but a few members have seen issues with the tune down the line.

I’ve only heard about PBMS and Torque in Auckland when considering a tune for Subaru’s, ST Hitec is also a well known tuner for Japanese cars in general. I would stay away from cheaper / unknown tuners. Unless they specialise in Subaru or know how to tune them well.

Thanks for the inisight! How about Subtech? they have quoted me $969, they take a copy from my ECU and send it to the UK

Eww...
So they are charging you the cost of a full tune but get someone in the UK to try modify it right and send back? Sounds like an expensive e-tune to me

Downpipe and PBMS tune is easy. It’s what I started with.

Sub tech are great for mechanical work and they've done all my pre-purchase checks for me (about 6 in total now), but if they aren't doing in house dyno or road tuning then I would look elsewhere. As Andymac pointed out, they're offering a mail order / etune for the price of a dyno tune.

 

The difference with a real world tune (dyno / road tune) is that your car is programmed with your cars running gear at running temperature / humidity / AFR / air temp etc etc for your stock ECU to work with.

 

An e-tune is essentially a basic recipe that's been made from data they've gathered from various other cars like yours and combined to make a map that's close to what they think works based on previous tunes for the same car.

 

Sort of like an "off the shelf" map that Cobb accessport has in the USA - its close but not exact, works but not the best.

Subtech are fine for mechanical work. My car has been there a few times. 

They are not a tuner

 

cobb is a tactrix cable and ECUedit software replacement after that’s it’s still a e-tune. That helps them sell their own parts. 

 

I got about 15% more power from downpipe and tune.

Best bang for buck on sgt :

decat downpipe and catback exhaust

remap

fuel pump be a good option as well

front mount if the budgets allow

 

Have a look at CCT for Subaru specific tunes:

Any reviews for CCT? they do reputable tunes?

I have a 2008 S-GT and I'm thinking of changing my turbo from the stock one. I have a Garrett T04E that I had bought several years ago for a project build and never used it. Can the ej20 manage that turbo? If yes, what if anything will i have to change? I already upgraded my exhaust to a cat back system and switched my top mount intercooler for a front mounted one and i also upgraded my fuel pump.
