Default 05 sti turbo replacement/set up

Ok so I gotta ask for y'alls opinion. About a week ago my turbo took a dump. The entire exhaust side just fell apart. I've done a once over and engine seems to be fine. With that said, a new turbo possible minor upgrade will happen. So I've looked into (per friends advice) getting a 16g. I've looked around on a tight budget and have read mixed reviews on a GSP 16g and 20g. Any feedback? Also, going to install new walbro 255 fuel pump, new down pipe and installing a Cobb AP V2. Also considered a bov with it all. What do y'all think? On a budget, not trying to make mad hp, just back near stock with a little bit of extra hp.

Skip the BOV, unless you just want it for the sound. Also, a 16g isn't really an upgrade over a VF turbo. You will need to get retuned for it. The only reason why I can see going with a 16g over a VF would be cost.

Cost was a big thing. I'll ditch the bov after what I've read a recirc is the way to go. The 16g with a Cobb tune and new fuel pump seems to be a very minor upgrade. 20g more worth it? Looking to possibly get a little more whp and wtq

The fuel pump isn't even needed. And anything besides the VF39 will require a protune. If money is tight, buy a replacement VF39 and be done.

You can run anything you want with a Cobb AP. But you have to get protuned if they don't have OTS maps that EXACTLY match what you have on the car.

A used VF39 in good condition can be had for $350

Protune=professionally tuned.

At this point, you would really want to consider getting a stock replacement (used to save money, there are plenty of good used ones) and take the mean time to read up on the car and everything about it. This will benefit you in the long run, and give you time to save money for any upgrades.
