Default Turbo Opinions

Hey everyone!

I really would appreciate some opinions. I need some unbiased and clear headed opinions. haha unlike the advice from some of my hp hungry friends...no offense guys. haha

So I just noticed that the flange on my turbo broke off. Im not sure if it was due to rust, bad seals, too much pressure etc... I honestly had no idea anything was wrong until a friend pointed it out. Im taking it to my mechanic tomorrow to have him look at it. There is a SMALL leak in result to the broken flange so I know a new turbo is in my future.

All my friends are telling me "get a bigger turbo" "more power" blah blah blah, But honestly I just want something reliable. Im not one for racing or autocross, I just love driving my subaru around town. haha! I have a bone stock engine and the only mods i have are a downpipe and exhaust. If I really wanted to build my car, I most likely would have done it by now. Its my daily driver so I dont want to get too crazy, and I know having a 12 year old car is always going to need repair every now and then, but I don't want to have to keep replacing the same parts all the time.

So here is my question:

Should I just get another TD04l? And say I were to upgrade my turbo to a VF34 or 22 (which are the ones i have been browsing at) What kind of other upgrades will I be getting myself into due to the turbo upgrade?

Like I said, I really would prefer something reliable and cost efficient, but if it happens to give me more power i wont object. haha I just want my car to run forever with minimal issues.

I just want some opinions from people who have experiences all different types of routes when it comes to turbos so i can consider my options. thanks guys.

I would stay stock in your case. A new turbo and supporting mods/tune will chew you up $ wise.

Seem like you don't want to go crazy. Keep it simple with another TD04.

The more power your engine makes, the more stress is placed on it and the quicker it will wear out.

Stock turbo.

Just find yourself a stock turbo for sale used on the forums and call it a day. Anything else your gonna spend a bunch of money on after buying supporting mods and a tune. If you upgrade in anyway you will have to do more then just slap a new turbo on. Also you will decrease reliablity always when modding.

I would definitely recommend sticking with a TD04. It's cheap, reliable and works great on the 2.0. My favorite turbo for a 205 is the HTA68 but I think it's way more than what you need.

Stock STI turbo or one of the basic bolt-on 16G turbos.
Taking a leap here assuming you have some sort of engine management to go along with that downpipe.

She doesn't need it. It would be a good bang for the buck if she wanted it but either way.

A VF39/43, STi TMIC, injectors and a tune would be a nice upgrade. You should be able to source all that for <$1000 easily. If not, just buy a replacement td04.

I would go with a used STI Turbo if you could find one. If not, yes stay with stock turbo if you are looking to not spend much money. If you have money, then build your motor and put a nice big turbo on. Big Turbo + built motor = reliable. I have a gt 30/ 76 R rotated turbo kit and I love the power. However I also have cp Pistons, eagle rods, arp head studs and etc. My motor was built right and then I added the big turbo and etc.. Im pushing about 365WHP conservatively and very reliable. Yes I can bump up the boost and change my tune to get a **** load more power out of it but I would rather have a fast reliable car. So it all deepens on how much money you want to spend buddy.

$150 for a stock td04 that might still work. How long would that last then?

Better dollar per hp sense to buy a used STI turbo without a cracked housing. Drop in a $20 used sti fuel pump or spend 80 on a walbro. Then mod her injectors or a set of used factory injectors to match like 08+ sti injectors.

Btw I spent way less than that made up $20k on a setup that makes more power than a 30R. More like 6k including act hd clutch and fw. Tack on another 3500 or so for built short block and figure x for tune costs.

So a td04 is junk because it's $150? I have three laying around that are all in great shape.

Not everyone wants to go bigger. Either way a well done 30r set up costs money. The majority of the population doesn't do their own work either, so tack on labor charges and it gets up there. I've got about twelve grand or so into my 2.0 set up, if I had to pay labor it would be up between 15-20k. Hence my "made up" $20k figure. Sure you can do it cheaper, I don't like cheap things.

Stick with the TD-04, switch to a cat less uppipe when you replace it. Buy 1 with a flex joint. You'll get faster spool, gain a few ponies, and not have to worry about that old cat breaking apart and eating your turbo and motor.

Don't like cheap but you recommend the cheapest turbo available lol Regardless I never said the mighty td04 is junk. It is a very capable hair dryer and I'll leave it at that.

I recommend one of the most reliable bang for your buck replacements for someone who just wants their car back up and running. Not someone who wants to dump money into their car for power they're not looking for.

After doing a little research I see where a little bit of the discretion is here... You're coming from building a 2008 STi. Have you ever built a GD WRX up to that kind of power level reliably? It's a completely different ball game.

Td04 would be most economical option.

Any sort of upgrade and you'll get yourself into buying a new fuel pump, injectors, engine management + tune, upgraded intercooler yada yada.

Even used you'd be hard pressed to source just the parts for under 1k. It'll turn into a money pit before you know it.

Even the smallest turbo upgrade is going to cost you a few thousand dollars. Once you factor in the aftermarket exhaust w/ uppipe, used turbo (which I wouldn't recommend), higher flowing injectors, larger TMIC (optional but optimal), used unmarried AccessPort and custom tune...yeah you'll be in it a little deep but the car would be a blast to drive!

Also, if you don't want to go the used turbo route and don't want to pony up the cash for a new one I'd give a call to Pure Turbos out in CA. They just rebuilt my ball bearing GT35R and did a GREAT job with it!

Prior to this car I had an 02 wrx bought new in 02 before any sort of budget friendly aftermarket in the US. I know a few things about them. Especially the earliest ones that came with the red light ring around the ignition switch lol

I'm not suggesting op upgrade to an 18G or anything. Just something more efficient and better paired for the ej20. Cheapest route obviously stock replacement.

Go with the stock td04. You seem to like where your car is. If you go larger, as others have said, you get into a pricier game. You need engine management, turbo back exhaust, potentially upgraded fuel system (depending on the size of turbo of course). Not to mention the car is an 02. Keep up with maintenance and enjoy it for years to come.

If you start throwing power at it you may get a less reliable car and could have transmission problems in your future too.

I guess it could but there is no need for it to. What I posted above is all she would need.

Used DP: $100
Used VF: $4-500 at the most.
Used STi/2.5WRX injectors: $200 at most
Used STi TMIC: $2-300 depending on condition
Taxtrix cable and OTS e-tune: $200ish
