I see 20psi on my EVoIII 16G by 3400 rpms. You don't really need much better spool than that.

For some, like with a 2.5l a 10cm 16g might be a good option. It's also 1200 dollars.

I bought my pnp hot side vf52 late last summer from 6speed and finally got around to installing it in my 2008wrx. I bought this turbo from their stock and was delayed because they never had some gaskets needed for rebuild. They too sent me a Perrin turbo blanket because of the delay. My butt dyno says it's a lot faster and virtual dyno show nice upgrades but haven't actually protuned it yet. Currently running Torqued Performance stage 3.52 map with all supporting mods. (Process west top mount, 3 port and turbo). Also have tomei eql headers and up pipe, Cobbs downpipe, aem intake and invidia q300.

I am currently dealing with a strange boost issue which I hope is a leaky bpv. I hit max boost of 20psi but it doesn't hold.

Here's the virtual dyno graph

I have been running Eric's stage 2 map on the my td04 since last November. I have only been running the new map for the vf52 for about a week and am on revision number 3. I'm sure the tune is not the boost issue or the turbo. I don't even see how the turbo could be to blame for the boost issue. I have an aftermarket bpv lined up and if this doesn't correct and hold steady boost, I'll look at pressure testing system at shop.

Chuck that plastic pos.
Does the turbo smart have differnet springs?

Either way that should help with holding the boost. Just dont use rtv on any connecting surface.

Previous owner is including the spring that comes with bpv and a softer one he bought afterward. Hopefully this corrects issue and my 6 speed review can be a little more complete. I don't plan on using silicone rtv. The stock gasket that comes with bpv is paper. Previous owner made a cork gasket. I'll probably do the same.

I hope you get your boost issue sorted to get good data for comparison. I have similar mods (AEM CAI, Tomei ELH and UP, GS EBCS, CNT catted DP, but still stock CBE and unmodified VF52) and I'm at 20 psi at around 3300 RPM in 3rd gear. Eric is still doing fine tuning on my map.

^^^ those numbers are kinda low with those bolt ons and @20psi
Is the tune conservative ?
I'm at 300/320 at 17.6psi no EBCS yet
Only intake , FMIC and catless DP

I'll be getting another tune soon tho ... I just added a bunch of bolt ons
Hoping for 315/335

I'm still going through an e-tune process. My road dynos have ranged from 300/315 to what you see in the graph. Assuming knock doesn't become an issue with some timing advance, I should see slightly higher numbers in the next few revisions. I am looking for a conservative tune as I track my car a couple times per year.

The numbers are low because its street tuned vice dyno. Either way numbers are just numbers.
All i have for mods om my 08 are tbe, 3port ebcs, intake, recirc bov, fuel pump, and the VF52.

I ran a PnP 6-Star VF39 on my STi with an EWG for a while and I was really impressed with the quality of work and performance on the turbo.

I would be curious how this would do on the setup I will have after my motor is finished on my 05 STi.
  • 99.5mm CP Pistons
  • ACL Race Bearings
  • One Step Colder NGKs
  • Grimmspeed uppipe
  • Tial 38mm MV-S
  • Grimmspeed EBCS
  • Invidia EL race headers
  • Invidia dp with Cobb cb
  • DW300 fp
  • DW850 injectors
  • AMR hardinlet
  • TGV deletes
  • K&N intake
  • E85

I'll still probably go with a Morrocco88 pipe set-up and a Borg Warner S200SX-56. Interesting idea though.

Pics of PnP VF39 from SixStarSpeed next to Greddy 18G. Been busy working but soon should have time to get the VF39 installed in my WRX along with a few other mods. Might go EWG still debating, at minimum I'm gonna install EWG uppipe and blank if off for future.
