Probably...I didn't go that far yet. Wanted to make sure first. So all I should have to do is drill the pill...the oil return was said to work (how can you tell from the picture?)...so I should be good.

The picture shows the oil return line. Just double check making coolant lines are tight and the oil return line is tight on the turbo. Drill the pill and your good to go.
I have a vf39 swap on my WRX. I hit perfect target boost

Yes. Cobb has a map for the VF39 that can be used until you get to your tuner.

you could also search on modding your stock injectors if your going for cheapest route possible.

adn as said ^^^ your current reflash won't work with the vf39 and neither will any of Cobb's shelf maps. The only year cobb has shelf maps for the vf39 is the 06-07 wrx.
I hate people who give out bad information. According to Cobb (I spoke to them yesterday), you don't need a pump for their maps.

That's why I always take things people on this forum say with a grain of salt. Half of them don't know their ahole from a hole in the ground.

I bought mine off ebay for 350, but it has a hair line crack. I am not worried about that because I have read where it does not affect to performance. Aslo the max I think I would push is 21 psi and that is not going to be at that for a daily driver, but to get a 1 pull on the track to see what it can do. It will also be equiped with a water sprayer.

Well I can't find any on eBay for a good price since I got outbid. I am contemplating buying a 16G from Spun instead.

Check the forums here and on iwsti.com. I got mine for $300 shipped at iwsti back when I had a vf39 (about 6 months ago)

^^ They are getting more popular and you will have to be patient. They go for varying prices, but be patient.

Yea, I'm working it. Now that they are coming with VF43s it seems that the VF39s are becoming more rare.

Yeah..its stock :)

Default Great thread

One question I have. My only mod so far is a 3" catback. What could I expect(if possible at all) if I only run a Vf39 with all else being stock? 07wrx.

If I drill the pill and just swap the TD04 with a Vf39, will this cause any problems? Could I still run a OTS map or should I leave it stock? I assume I would not be making target boost.

I guess in short.. What is the minimum to run a vf39? And what would the result be?

Thanx

I have heard where guys have run the stock boost on the VF39 on the stock pump and stock injectors and they do feel the difference. That swap could up you about 20 horses. But I am a bit skeptical about doing that.

yeah..no EM. I would think that by running stock boost on the VF39 the stock ECU should be able to compensate by adjusting parameters. This setup should yield better topend results.

Just a thought. I am looking to do this becasue I only want a little better pull from 4500 to redline.


Any ideas here? could this be possible?

cheers

I wouldn't do it but that's just me. I'm not sure the specifics but I am guessing the ECU wouldn't automatically know if you were using a VF39 or TD04 and 15PSI on one is not the same on the other for example.

Terrible idea, but it's your car. The ol/cl delays on a stock car will mess you up and the fuel and timing tables aren't scaled to the loads that your car will see with a vf39. Don't do it.

Default vf-39 on 2006 wrx

I just did a vf39 swap on my 06 wrx. what a huge difference from stage 2. on a mustang dyno it was 280hp but we found that it had a leak at the uppipe so I think it will dyno higher..... getting a pro-tune this week and will post results after the pro tune.

Almost forgot to do an update. I finally got the turbo upgraded installed and oh man does boost in like a punch from Mike Tyson. I ended up dynoing @ 280HP/330TQ. It was on a Land & Sea Dyno.
Mods are just in case anybody is wondering, Gruppe-S headers, Gruppe-s lightweight crank pulley, Injen CAI, ERZ downpipe, SPT catback, STi tmic and VF-39.

I was expecting higher HP but the car feels awesome either way especially with all that torque. The difference between stock and Stage 2 is nothing compared to Stage 2 and the VF39 upgrade. I managed to hit 120,130, 140 with so much ease (had some open road like at 3am this weekend). You also notice alot more power above 5k rpms unlike when I had the car at stage 2.

One of my buddies installed his VF turbo without EM just to drive it to the shop 3 miles down the road and blew one of his cylinders, . But in regards to getting more power til redline definatley a good choice for little money.

yea same here..... I was execting round 290 but 280 still is way better than stage 2. I'm running a cobb up-pipe, hks dp, borla xr-1 all catless. also k&n typhoon intake. I want to do the borla header soon and a lightweight pulley set also. what a huge difference from stage 2! can't wait for the protune and another run on the dyno.

That is just crazy.
He was begging for trouble, and I am sure he never took his time.
