I wouldn't recommend it.

I was looking on COBB forums and everything I saw pointed to no. The main difference between the 39 and 43 is the size of the wastegate and exhaust housing IIRC. Even so, I'd wait till you can get a protune.

thanx dude. i guess i'll focus on the vf34/39 and 16g
The VF43 is good, just not without a protune.

The Cobb forums point to no to the Stg 2 VF39 map with a VF43, except maybe to limp to a protuner...

I'm looking to go the same route (either VF39, VF43, FP18G). Maybe add a fuel pump. I've read that the 06-07 WRX injectors are fine for these turbos.
