Seems like I have a friend of a friend of a... who is an engineer in the Gyor, Hungary Audi plant, where the 1.8T engines and TTs are being manufactured. Supposedly wrote his Masters' thesis about this thing. I asked him questions regarding the chipping, tuning, max safe performance of the 1.8T. He is asking for my engine number. Anyone knows where it is? Anyone able to explain so my wife could find it over the phone?<p>Anyways, if you have a question you wanted to know about the 1.8T, post it here. I will compile the questions, send it to him and post everything I find out.<p>I will not send him any more engine numbers, but will do everything to get ranges of engine numbers or manufacture dates regarding possible differences in the 1.8T.<p>Shoot!

1: Was the 1.8 developed as a 190hp engine?<br>1a: What is a safe level of boost? <br> (Are the internals up to the additional boost?)<p>2: If he were to upgrade an ECM, who's chip would he trust the most? :) <p>3: How closely related is the 20v turbo engine to the old, venerable 1.8 16v VW engine?

How long is the turbo designed to last? (miles/years?)<p>Tom<br>1.8TQMS

What is the max hp can the tiptronic handle?<br>Just want to make sure all the tip in A4,A6,A8 is it same?

all tuners (see hoppenmotorsport.com, for example) agree that 220 is the limit.

1. How safe is it (internally) to upgrade to the 235 hp kit.<br>2. Is it necessary to upgrade the exhaust after a 1.0 bar chip upgrade.<br>3. Is it a bad or good idea to get a P-flow?<p>Thanks,<br>Oscar<br>97.51.8TQM waiting to get chipped

Here it is:<p>- For a 200HP (chipped) car, do you have to upgrade the intercooler(s), especially if you go racing sometimes?<p>- I know it sounds silly, but is there any oil brand and weight that he personally likes?<p>Regards,<br>Andrei D.

1) What are the differences between the 180hp and 225hp engines?<br> (apart from the different turbo) supposedly there is a difference between<br> the pistons/valves/head or something like that.<p>2) What does the Motronic software on the TT's do differently/better in that<br> engine than the A4 1.8T engine?<p>4) Can the engine software (motronic X.X?) on the TT's be integrated into<br> the A4, if so how difficult is it, would it be a straight ECU swap?<p>5) How long is the 225hp 1.8t designed to last (mean time between failure I guess)<br> AND in particular what to keep an eye on, what's expected to "fail" first?<p><br>Terence<br>1.8TQMS<br>
