Default Upgrading the Turbo 06 wrx

Hey all,

Looking to upgrade my stock turbo, a friend has a vf39 in his, and recommended it, but ive been reading that they are prone to cracking and that there are other models out there that are a better choice. I dont want to get into building the internals as Im not looking for 400whp or any of that fancy stuff. I just want a bit more top-end. I dont mind a few supportive mods if necessary, but trying to keep this as simple an upgrade as possible to get a few extra PSI.


Anyhow, here is my mod list:

•Cobb SF intake +box
•STI intercooler
•Invida Catless DP
•3" Catback

I do have a Cobb AP as well, and will take it to a pro tuner if necessary.


Any suggestions?

The crack on the vf39 doesn't have any effect on the performance of the turbo. Mine is cracked and has been like that since I got it. I would recommend a walbro pump to go a long with the setup.

You have done zero searching here which means the odds of you blowing up your motor are about 2:1.

1. Find a tuner in your area or one that does internet tunes. If you need help, reach out in the SCIC forum.
2. Open a line of discussion with them as to what suits your needs.
3. Read the sticky threads at the top of this forum for background information.

Thats very helpful. thanks for the input. Im leaning towards the vf39 because they are fairly easy to find. and appear to be a direct bolt-up.

Actually. I have done quite a bit of research, however I still prefer to ask when there is no direct answer available. Unfortunately I am not blessed with hours upon hours to read hundreds of threads to find the bits of information that I need. Also, I fail to see a correlation between my search habits and the health of an engine. I'm not exactly new to cars or turbos.

Sorry for asking a question on a forum, I didnt realize that wasnt the entire purpose of this website.


Besides that, I have contacted a few tuners, but I much prefer to discuss my options on a forum with thousands of voices and members, than talk to a shop of 2-3 people. Not that I doubt their voice, but in my experience, shops tend to be biased towards products and services that they sell rather than finding the best suited solution to my needs.

Thousands of voices that are more prone to being wrong or misinformed? You realize many many many posters are just like you, and simply say what they have heard. Your tuner will give you a no BS answer to your question. Will he try to sell you something? Maybe, but you can say no. Your random average user will simply tell you what you want to hear. (I'm not being biased or calling any members idiots, simply saying there is a LOT of regurgitated info on here)

good point. your better off digging up the info than asking for opinions.

but to answer directly that is a fine turbo to upgrade. they are plenty and affordable and will give you the results you are looking for.

if you really want top end you will need an even bigger turbo but thats a lot more $ and mods you clearly dont want a part of.

if you have the budget id reccommend an 18g over a vf39 but for the cost the vf39 is tough to beat

Valid point. I guess I am a bit naive in expecting that people would be truthful and helpful on the internet.


Thanks for your help guys.

I wouldn't say naive. Just expect people that have no idea to comment, so take everything with a grain of salt. (Unless you background test everyone )
