About me. I am a total newbie who just got his first Subaru. I have a 2004 forester xt with a blown wrx turbo in it and I am looking for a replacement turbo. the car is stock for now so there is no mods or tuning done. My goal is to drive it this year as a daily driver and work out any/all kinks I find with it. once I have it running well and the suspension and brakes are setup I will being engine mods. The goal for this car is to be a fun car for the weekends with the family and camping and biking trips or car show/club meets.



My question is what is a good stock wrx turbo that I can put in to replace the current one? and where can I get a good deal on a new one?



thanks for all the help in advance.


You definitely have options.

You could always replace the turbo you have with a TD04HL. Itíll be a little bigger and be close enough so you wouldnít really need a tune.

However you could always do the famous, VF39,43,48 STI turbo swap. You can make great power with supporting mods. But it should be able to run on your stock engine fine with a proper tune.

So you can do a little more power or you can do decent power with tune.

Getting one isnít terrible.

Classifieds on here will have them, Craigslist from time to time, ebay will have used ones, car-part.com, heck even the dealerships, youíll pay a pretty penny though.

I've recently been given the go-ahead by the Missus to upgrade my MY08 Forester XT's turbo and with the multitude of threads i come across I find myself overwhelmed. I was looking for suggestions on what would be the best options to preserve daily drivability whilst giving me the power I lust for. I'd prefer to have more power with similar profile with bigger numbers ( I plan to create a sleeper to compliment my muscle car.) If anyone would be able to recommend a few ideas on a turbo that would not be too crazy, I'd appreciate a place to start.

Thanks in advance.

Seems like Iím the only active guy on this thread lol.

Iíd start with a STI turbo, VF39, VF43, or even a VF48.

With supporting mods you can put down some surprising numbers.

Full exhaust, STI injectors or after market injectors, intercooler, headers, uppipe, good set of spark plugs, maybe a fuel pump. Thatíll get you started. You can research other swaps people did and get a feel for the numbers. You can also build up the sti turbo while itís out of the car and thatíll help too.

You have quite a few options but I think what I mentioned would be a great starting point.

Posted above is one option. However, I wouldnít swap anything less than a 20g on it (Fmic, 1000cc injectors, 255fp, full tbe, intake) and bigger if you go built block.

Thatíd give you 300-400whp depending on how much you want to turn it up and fuel used.

Hey all,

Total noob to turbos here. I've been reading the turbo faq thread, but obviously have tons to learn. I was hoping to get some direction from you folks with suggestions on my best options.

Car: 2016 sti
mods: FMIC, intake, killer b headers, perrin exhaust, grimmspeed boost control, 320 fuel pump, perrin fuel pressure regulator, 1000cc injectors, AOS. Don't think I'm missing anything else major.

I'd like to get more overall power, but would primarily like more power at the front end and faster spool. Not sure if it's possible to get both in one turbo. I'm not super concerned with power at the top end, but obviously would like more if possible, but my focus is more at lower gears.

I'm curious to see what you all think would be my best option here.
Thanks!

Hmmm looks like you have all the ingredients.

I would look into a twin scroll turbo. You get constant boost. Starting from low rpms to high.

Only downside is youíll probably have to switch your header, uppipe, and down pipe to make it work. Could be worth it though.

Kinugawa offers a 20g twin scroll that is a beefed up vf37 I believe. Overall ratings for it seem rather nice.

Other than that youíll be looking for a turbo with a lot of spool and quick. Ball bearing would be a good idea to consider as well. There are tons of turbo options for ball bearing turbos that can make any turbo spool fast for more acceleration.

I can do some digging on that kinugawa one. They have a lot of twin scroll options.

I had looked into twin scroll a little bit, but I'm really hesitant as I'm not convinced it's worth the money. Also because I would then need new headers as well (the killer b are maybe six months old).

At this point I think I'd rather do a regular stock placement turbo upgrade since I can keep my headers, killer b does a trade in program so that I can trade in my killer b uppipe for an uppipe for the ewg, and my cost will be much lower overall

Look into atp turbos for the ability to retain your up pipe, and still be able to go ewg. I have a gt3076r. The wastegate is mounted right off of the hot side. Very easy to remove and service.
Although ball bearing, it does push power to the right for better mid to top end at the cost of some low end torque. Just the price you pay for a bigger turbo, but something youíll get used to quickly.

I have VF37 in my 04 Forester STI (2.5L) and the spool is awesome. Starts to build boost at around 1600rpm and full boost is achieved at ca 2400rpm.
At 6000rpm it holds 1 bar (14psi) very well. The response is immediate.
The acceleration is very linear and very N/A-like.
