I have not long had my 06 TBSTI Manual and am already wanting to do some work to her. I am wanting to do the following mods and would like some input from you peeps as to where I should be heading.... I am looking for power of around 220-240awkw.
Turbo - What should I be looking for here, brand, size etc ? Am wanting something which will pull through to redline (not that I will probably ever get there) and good mid range as well....
Are you wanting to stay twin-scroll or convert to single-scroll? You will find a bigger range of turbos with single.
Intercooler - It's the old story, TMIC vs FMIC, but what's best for the power I am chasing ? I would prefer a good TMIC to keep the stock look but will entertain the notion of the FMIC if the power gains over a TMIC are there.
Pretty controversial argument there.. Purely up to you, unless you're pushing 250kw+, TMIC should be just fine.
CAI - Do I really need one of these, and if so what type and brand should I be looking at ?
Not required, a new panel filter should do the job just fine, until you start pushing 220-250+, in which case full intake would be the trick.
Exhaust - Will be getting a 3" TBE but how the dump pipe will connect to the turbo will be the question depending on the turbo that I get.
Is your car manual or auto, I know the manual DP won't fit Auto, due to the larger box, therefore I assume auto would fit manual.
You will have to decide on your turbo before you get a DP.
Uppipe - Do I need a better one ? was gonna grab a MINES one from dr20t but that sold so am back to square one.
Not really required unless pushing decent power, in saying that, this decision will be swayed by if you stay twinscroll or not.
Injectors - Was looking at some ID1000's which I think will be more than enough, is this a good option ?
For 220-250kw I would imagine yeah
Tune - As I am in QLD I have no idea of who would be best to do this. I have heard good things about Godzilla Motorsport @ Wakerley and was gonna take my old Foz there but never got around to it. Don't really wanna take the car interstate either.
I have heard good things about Northside 4x4, they have done a lot of Subaru tuning, otherwise Chiptorque get a good rep too from what I've seen.
Will also be getting a Walbro pump in the near future.
After all of that, is there anything else I need ?
Am also wanting a different grille for the front as well, any recommendations here ?
You can go aftermarket, Corazon, zero/sports etc or can do a DIY mesh grill which looks the part, if you've got time/patience.
Would appreciate any feedback you can offer, have read a few of the members rides and the mods there but some of them are very long and would prefer just to pick people's brains.
Thanks
Brett.
Purely my oppinion, I am not a mechanic nor a Subaru expert.
Good luck.
Hi Zach,
Thanks for your input here, we will have to catch up sometime and compare notes
In regards to the points you make above.....
1. I would most likely convert to single scroll as I agree there's bigger range of turbos, especially the Garrett ones (and one of those I just missed out on, a GT2871). But would there be a good twin scroll turbo that would get me to the power figure I am looking for ?
2. In that case I would stick to the TMIC, what sizes or brands should I be looking for ? I noted there's an AVO one in the FS section, would this be a god option ?
3. Considering that I am looking for 220-240awkw, the full intake would be the go. What brands or designs should I be looking for here ? I had a 3" CAI from the inner guard on the old Foz, would this be a good starting point ?
4. The car's manual so wouldnt be an issue, but do agree that I should probably do the dump pipe when I decide on what turbo I go for. Will most likely do a 3" CBE to start.
5. Being that I will most likely go single scroll, should I invest in the uppipe ?
6. Will look for those injectors then for sure.
7. I will investigate Northside 4x4, have also heard some god stuff about them and are localish to me as well.
8. Where would I find a Corazon or Zero/Sports grille ?
Look forward to your responses.
Brett.
