IHI VF30 upgrade

1. Ok, I know everyone here says for a bigger turbo you need:

Upgraded TMIC/FMIC
Fuel Injectors - 565cc
Fuel Rail
Fuel Pump
Turbo Back
Catless Up-pipe
and Engine Management

2. Well my turbo just went out the window the other day, was leaking coolant and well... fins dug into the housing real bad. So now I need a new Turbo, well I got a VF30 from a local shop I know for cheap. I'm broke so I'm trying not to spend money so the guys at the shop said they can put a utech on and tune the car so the turbo will be safe to run on what I have.

3. I already own a Cobb AP. Well Cobb makes a map for the VF30 that only requires a Turbo Back Exhaust and STi Injectors. Cobb says it'll put out 320hp and 295lb-ft. Obviously this route peaks my interest due to the low cost factor, that is relative to my other options. I contacted Cobb for more info but they seem to be uninterested in return my e-mail, so I'm asking you guys. Here is a link to the specifics on the Cobb AP Map.

4. I already have:
New motor: EJ20, Stock 04 WRX motor (now about 1,800 miles on it)
Invidia WRX Racing Cat Back Exhaust Type R
Kartboy WRX STI Exhaust Hangers Standard Length
Cobb Tuning SF Intake System Black WRX STI
STi Subaru Hood Scoop 2004 - 2005
Cobb 5-Speed Shifter Bushings
Cobb Double Adjustable 5-Speed Shifter
Greddy Subaru WRX Counterweight Shift Knob 5-Speed
Carbign Craft Subaru 04-07 WRX / STI Carbon Fiber Exhaust Heat Shield
STI WRX 5MT Transmission GroupN Mount
Power Enterpise WRX/STi Timing Belt
Beatrush WRX/STi Forged Pitching Stopper
STI WRX Stainless Steel Braided Clutch Line
ACT WRX Street Clutch/Prolite Flywheel Combo
Samco WRX STi Radiator Coolant Hose Kit
NGK WRX One Step Colder Spark Plugs

Thanks a lot for any info!

The reason I'm staying away from used is because I have already spent the money on the spanking new block and heads. I'm planning on a new set of gears in the late summer/early fall. I got the VF30 for less then $695, but if I had known I could get a stock turbo new for that I would have done that, but now I have made the investment in the VF30.

Also I already have the VF30, and I scraped up the money for DW 565cc Injectors, Invidia Downpipe and Up-Pipe(catless), and the Walbro 255lph Fuel Pump Kit. I'm just waiting to order that because I would like to know if it'll be safe for my baby if I use the Cobb with this set up. When I talked to the shop they wanted to sell me the utech, they told me the AP couldn't do anything for me. It just felt like they were trying to get $1,500 of business out of me.

Thanks for the input guys!

It's actually Lebanon, PA. Right off Route 72. Small little building, it's amazing the rep that place has for such a small place.

The Cobb map should be safe for what you want to run. Do not switch to a UTEC. If nothing else you can by a custom map for your AP for about $150.

If you already have an AP then there is no reason to switch to the UTEC. The shop is full of carp.

Sorry I have another quick question, would the APS TMIC be too big for this set up? should I stay with my stocker? or maybe just the STi TMIC?

You need something bigger than stock. The STi TMIC would probably work if you're just using a cobb base map but the APS unit is more than twice as big, it would be ideal.

I don't know why you're ONLY getting a VF30...

Yea I like the APS TMIC, I just didn't know how big would have been too big. I got the vf30 cause the shop had it laying around and it was next to nothing, and my turbo fins thought the housing looked tasty so they took a bite. Well had a feast really.

Thanks a lot!

Well, it's a TMIC so it's not going to be as laggy as even a tiny FMIC just due to the shorter piping. It's safe to say there's really nothing bolt on that's "too big" in terms of TMIC. Maybe bigger than you can exploit with a small turbo, but not a negative.
