Thinking oof buying a modded STi
I am thinking about buying another STi and found a pretty decent looking one with some mods that include a front mounted intercooler, suspension work and some other goodies. I went to check the car out in person yesterday and the guy who owns it is a wholesale auto dealer that buys cars and sells to auctions.
I was in a rush (in between sales calls) yesterday when I checked the car out and showed up to his dealership unannounced. His dealership is located in an industrial office park and all of the cars are inside the building which is basically a warehouse (reminded me of the Gone in 60 seconds shop but cleaner).
When I got there I asked him to fire up the car and it started without a problem and sounded fine. Not that I had any plans on test driving but he said that he needed a check in hand or serious offer before he would allow a test drive which I thought was odd as I rolled up in an 07 Porsche. He is firm in his price of $22.9K but I am sure I could get the car for less with a cash deal.
My question is this. Would the mods that are on this car have any significant drawbacks that you would be concerned with? I would post to the STI forums but I don't want to tip them off and potentially lose the deal.

I would want to know owner history before getting a used STI or EVO.
You never know how it was driven or taken care of. I know a lot of STI ex-owners who got rid of their car because they knew they drove it like they stole it everyday.
Good luck!

Engine management. That is the most important factor when looking at a modded STI. If it has much more than a turbo-back exhaust (looks like it does!), then custom tuning is really a must for these cars. Find out who did the tune, then find out if that tuner is well thought of.
Bad mods for subaru turbos:
intakes (Stock intake is generally thought to be good for all but the most beastly cars). That being said, front mount cars usually have a short ram intake for space reasons.
blow-off valves (Stock is a bypass valve that vents the pressure back into the intake, the ECU cannot be reporgrammed to account for this so it runs rich. Stand-alone engine management can take care of this, but it is rare). Front mount cars almost always have a BOV, and it looks like this one does. It can make the car run rich between shifts.
The STI (they dropped the lowercase "i" last year) six speed is a very robust transmission--shouldn't be any problem there.
The VF39 turbo can have issues with boost creep when coupled with aftermarket downpipes. Try to do a nice long third gear pull and pay attention to the boost gauge. I would venture to say this car has a bigger turbo, maybe an 18G or 20G.
Speaking of gauges, a boost gauge and a EGT is pretty much mandatory for modded turbo cars. If there is no EGT, then I would be wary of the car. A good wideband O2 sensor is an alternative. If there is a EGT, make sure the temperatures are good (~1200, less than 1600 for sure) after a long pull at full boost. I saw only one gauge in the pictures, but a another one may be mounted up higher.

Looks like a sweet ride. brizey, as this particular STI has an FMIC do you think an Impreza 2.5i hood could clear the intake piping? (Just curious)

He said he is ok with me taking it to a Subby dealership to check it out but with all the mods I wonder how helpful they would be. I need to find a good tuner in the metro-atlanta area.

The pictures don't do that engine bay justice. When I saw it yesterday everything was polished, neat and clean. I bought my previous 04 Sti for $23,000 and it only had 14,000 miles on it. Won an auction on Ebay from a Ford Dealership in Macon, ga. To this day I think they thought it was a regular Impreza.

There are plenty of STi owners who have gone FMIC and gotten a RS hood.

If you own a 2007 Porsche, then you should be able to afford this one with no problem. Having that said, now just leaves you the headache part

I would be shocked if he had a FMIC and no TBE. STI's usually use the stock up-pipe because it has no cat. Headers are rare in subaru-land. FMIC usually goes with a bigger turbo, hence my comment above.
Typical subaru power mod path:
EM (engine management)
UP/TBE (up-pipe/turboback exhaust)
Turbo (pre-2007 USDM STi has an IFI VF-39, upgrades are usually Mitsu 18g or 20G)
FMIC (Front mount intercooler)
EWG (External wastegate)
Tumbler valve delete
Internal/block/cams etc.
Check your regional forum on NASIOC to see if you can find out who owned the car. Anyone with that many mods is probably a regular there.

The car might have had a turbo upgrade which might've been taken off the car prior to the sale. Hence the bigger intercooler. Or it may just be there for some sort of bling factor

People use RS hoods. People also buy aftermarket hoods as well. Some leave the stock hood on for stealth reasons. There are also inserts around that replace teh scoop.
