First off, if this should be moved to the tech section I apologize. This is a long story, so if you don't want to read it all, I'll include a summary at the end. The point of this thread will be for me to pick the heck out of your brains 
My background:
My very first "fun" car was a 95 Talon ESi. I learned that thing inside and out, and ended up building a turbo kit for it. Once I blew it up I fully built the motor. I learned the majority of my wrenching skills on that car, and don't regret owning it for a second. I've also own an 04 WRX, 03 Mustang, and a few other toys here and there...so I'm not completely helpless when it comes to turning a wrench!
That being said, my knowledge is limited to the 4g63 platform. I hesitantly left Indiana yesterday with a 92 Talon TSi AWD (I live in Wisconsin), and boy is this thing in need of some TLC. The kid who sold it advertised it as CLEAN, with a great looking mod list and low miles. And the asking price was $3800 - Which seemed fair for a clean 22 year old car. He sent me a bunch of low-res pics, nothing that showed how dinged up the body really was. Bent lips on 2 wheels, scratches and dings all over, windows don't work for crap, interior is okay except for panels missing screws and for some reason the seat belts were in the back seat. Head unit isn't even mounted in the dash, Hurst shifter wasn't attached right (idk how you screw that up), and much more. He answered all of my questions with lies.
The second I got out of my truck to look at this thing my jaw dropped. "Clean" is the last word I'd use to describe it. I was pissed, and I let the guy know he wasted my entire Sunday. I left with the car, talk about buyer's remorse. But now I'm starting to have a little hope - It would be such a fun Winter car, even with its beat up body. I paid what I thought it was worth, which was much less than his asking price, and limped the thing 500 miles home. It runs like crap. I haven't had a chance to look at it much yet, but will after work today. Right off the bat I noticed an open vacuum line hanging off the throttle body, which might attribute to why it idles high and like crap. But also, the car supposedly has 550cc injectors and a 16g turbo, which it definitely can't be tuned for. There is soot all over the back bumper and it bogs down like crazy throughout the whole RPM band - particularly at 6k.
He said the previous owner said it had DSMLink v2, but I only see an Eprom ECU that isn't socketed (attached picture). It has a 16g of some sort, I can't quite see the numbers in the picture I took this morning so I'll have to look when I'm home from work. It idles very high, at like 1500rpm, and is rough. It fluctuates, and somtimes dies. I think this might be due to the Fidanza flywheel and vacuum leaks.
So where the eff would you guys start? I'd like to get this thing back to a simple running state. Put in stock injectors? Take out the manual boost controller? It peaks around 15psi right now. Also, I'm sure after 500 miles of highway driving under rich conditions the spark plugs are fouled. So I'm going to pick up a set of NGK BPR6ES on my way home tonight and put those in. Also going to trace down all the vacuum leaks I can, and do a boot leak test if I can find my tester. CEL is on for supposedly a coolant temp sensor, maybe I'll knock that out right away.
TLDR? Cliff notes:
Picked up a neglected 1g. Here's the claimed mod-list:
-Built TRE stage 2.5 trans with lsd, double synchro first and second, evo 1st and 5th
-4 spider center diff
-New head as of last November
-ARP head studs, Cometic head gasket
-16g turbo
-Balance shaft delete kit
-Slowboy racing front mount
-Lsd read end
-550cc blue maxx injectors
-Dsm link v2.5 *turns out it's just an EPROM Ecu, no Link*
-Fidanza aluminum flywheel
-Centerforce dual friction clutch
Car runs like poo, want to get it back to a simple running state. Right now boost is turned up to 15psi via MBC, and the bigger injectors/turbo are not tuned for. Here is an album with a few quick engine bay shots and a pic of the ECU- http://s52.photobucket.com/user/tec_41/library/1g TSi AWD
Where the heck would the 4g63 experts start?[DOUBLEPOST=1413832516][/DOUBLEPOST]The Eprom ecu I appear to have (MD145903) is from a 1990 supposedly. And since mine is a 92, I read I'd have to swap pins 6 and 14. Anyone know the reason for this?
