I just got off the phone with both TEC and Autothority, they BOTH tell me everything will work.
The turbo I'm considering is the (TEC) TE-350K ($850) which they claim will make approx. 340rwhp @ 14-18 psi boost, and will work with the stock MAF, injectors, fuel pressure regulator and fuel pump. (all very important to me) All they say is needed is to have the chips re-mapped and according to Autothority, they can do this no problem for $100.
This sounds to be EXACTLY what I was shooting for, I'm just curious if anyone else has done it and if so, what were the results.

Doc, they said for a $100 they would burn chips for you for that turbo? I called them up and they said $400 minus trade in of $200 if you give them your stage 2 chips. Where do you get that turbo?

RAD The turbo is from<a href="http://www.turboengineering.com" target="_blank">TEC</a> talk to Jason. Their turbo is considered to be a bolt-on with the exception of modifying the water inlet to clear the housing.
I spoke with the sales manager (Ali) at Autothority (703-323-6000 x405) and explianed I have the Stage II chips and wanted to upgrad my turbo to a Garrett. He said, "no problem" send the old chips in with the details of the mods I've made and for $100 they would "re-map" them for me.

Is that so you can stay in class E?

340RWHP on stock injectors??
Uhhh...I didn't think that was possible...
Too bad I sold my autothority chips...looks like I'd have $100 or at least $200 custom chips otherwise....
Maybe I'll ask TT or aka951
who's TT btw?

I made 281rwhp on my car using stock injectors @ 100% duty, 3 bar fuel pressure.

Jason... while I must admit, the thought had crossed my mind, I would never be satisfied with any wins I might get.
Frankly I've been winning or at the very least, placing in the top three in my class for a while now in the PRC, but I must admit there's not much competition in that class. I'd rather finish further up in the pack over all in a higher class. (Most likely GT2)
It's acutally more of a financial matter than anything.
I'm in the midst of a rebuild that is likely to run me around $7000 which I frankly cant afford to begin with. I just cant see spending that kind of money and having the engine out without "taking care" of a few other things while I'm at it, getting some better performing in the process.
While a new MAF, injectors, fuel pressure regulator, engine managment system producing 400+rwhp would be sweet, I just cant do it right now.
Not to mention there IS something cool about having a 350rwhp car that looks almost stock under the hood.

I ran a K26/8 with a modded compressor and APE stage 2's @ 18psi and had a hell of a time tuning it in. Add in exhaust, FPR, and a MAF, and it was on the verge of being too lean. Midrange gets rich, top end leans out. As stated, the stage 2's have a map that expects dropping boost, and starts to limot fuel.
I had my ARC-2 in full rich, and higher fuel pressure and still could not get it just right. I am sure some dyno time could have made a diffrence, but it would not be just right.

Russ,
Pardon my ignorance, but what exactly are 55 #/hr injectors and what's the difference between them and stock? (or ARE they stock?)
Also, will injectors for another Porsche fix the problem, i.e. 928s etc?

Injectors are rated by their capacity to flow fuel either in cc's/minute or pounds/hour at a given test pressure (usually around 40psi). Our stock injectors are rated around 390 cc/min. and 55 lb/hr injectors are around 577 cc/min.
Horsepower is directly related to the lbs. of fuel burned and 340 rwhp requires more lbs. of fuel than your injectors can deliver at acheivable fuel pressures.

I don't know. Our cars were the highest hp for the fewest cylinders (in other words, probably the biggest injectors spec'ed by Porsche). Maybe somebody with broader experience might chime in?

Doc it really depends on the car. most 944 turbos injectors are good for 310-320 wrhp, however I heard of some 944 turbo that got up to 370 wrhp on stock injectors 
I believe Konstantin mention that you can upgrade to 993tt injectors. If you were to purchase new injectors with would run about $350.

Ken,
You comment certainly has my attention. Do you know of any sources or discussions I could referrence?
For the record I asked about factory injectors because I have access to much better deals on them than aftermarket. Let's face it, I'm not too thrilled about having to spend $550+ on injectors added on to my already $850 turbo and $100 re-mapped chips.
