Will it take it?

[01svtL]

hey guys
I'm looking at a 2001.5 A4 that has had an upgraded clutch (supposed to be good for 400 hp) and brand new cylinder head (stock Audi) and gasket done within the last 5k miles. It currently has a stage 1 chip in it. I was wondering what was involved w/ a stage 2 and if the car will handle this power without a problem. (Stage 3 requires changing turbos and whatnot right?) The stage 1 is pretty quick, but I'd still like to have a little more if it won't hurt the car, especially if it's already set up to handle the power.

[01svtL]

By the way, it has been upgraded to KO4 turbo.

[Militant-Grunt]

A stock motor can comfortably handle around 300awhp. After that you start to worry about shooting rods out the side of your motor. A k04 wont come anywhere near maxing out the motor, if you go with something bigger such as a GT2871, then you'd need rods.

[01svtL]

OK good.

Then what I really want to know is what can be done to add a little more hp without going crazy like changing the turbos and whatnot. This will be my daily driver, but I still want to have no problems passing on the highway or anything.

I just went back and looked, it's an APR stage 1 chip for 93 octane, and the clutch is a Stage 2 (which he believes to be good for 400 hp). It was a decenlty stiff clutch. It felt comparable to the stock clutch in my 2004 Mach 1.

if it has a k04 turbo, than the first thing youll want to do is switch from the apr software(its for a k03) to the GIAC k04 file, since its an 01.5, doing the hammerfile with all the goodies should net you some nice results

[01svtL]

what are all the goodies? just tweaks in the tune? or are you talking things like fuel upgrades etc...

in case you can't tell, i'm new to turbos. i'm used to n/a and supercharged motors (fixing to sell my second Lightning)

For the K04 turbo, you have a option of two software flashes.

K05 file - Standard non aggressive setup, requires a 5 bar fuel pressure regulator

And for 2001.5, the aggressive file is the Hammer file, requires a front mount intercooler, larger injectors and a free flowing exhaust. (Stainless steel after market exhaust or custom setup with high flow mufflers, if you don't have a cat its even better.)

^ Thats not for 2001 models.

2001 and 2001.5 cars use the GIAC Hammer file. Since you have a K04 and a better clutch, you're pretty much all set to run 250 hp (crank) which is pretty decent. You live in Texas so you will need a larger intercooler. Contact GIAC or a GIAC dealer and they will tell you w/e you need for parts to go Stage 2.

[01svtL]

How much do the intercoolers and the GIAC tune normally run?

tune is $500 and the intercooler is $200 to $700

[01svtL]

tune is $500 and the intercooler is $200 to $700

haha jesus, that's quite a broad price range! are there differences to justify the $200 over the $700, or does it just depend on where you get it?

how much is the Hammer tune? About the same?

By the way biketsai: I sent you a message about your car yesterday...

[Nebone]

The intercooler price range is an ebay intercooler DIY (very good and cheap) or a ready made quality branded intercooler where $700 is actually cheap (normal price is around $1000)

[01svtL]

Oh ok. You have to buy extra parts to make the Ebay IC work or something? I'm assuming there's a writeup with pictures somewhere on here showing how to do it?

[Nebone]

Use the Search button and you will find anything your mod desease desires.

[biketsai]

I have replied to your email with pictures. Did you get it?

[01svtL]

I didn't get it. Please resend to [email protected]. thanks man!

Thought 2000 was hammer. Guess its the other way around.

[biketsai]

two emails sent

[2001A4QUATTRO]

2000 = J31

[VTAudiA4]

Or you can just go GTRS....(Says the guy with a K04)
350CHP but you would need all the supporting mods.

How much for one replacement with all the supporting mods? Runs about $4k I'm assuming?

What would be the best way to get it to 250-275 hp? I don't really want to drop several thousand dollars on a car like this if I don't plan on going all out with it, and I don't. 250hp seems about right for a daily driver though. I need it to get out of its own damn way haha.

Buy my car! haha.
It already has a new T28 with ALL supporting mods and makes around 325hp. I get 23-24mpg (all city) on my drive to work everyday with some spirited driving inbetween, but never abused.

[01svtL]

I like your car alot man, but I don't want to spend that much right now. I sold my Lightning tonight so I can get some bills from college paid off and put a little money in the bank. Your asking price is about $3k more than I'm in the market for. Sucks, I know. If you decide to come down quite a bit within, like, the next 3 days, let me know haha.

Lol, I doubt I will be going down that much, but if you DO decide to upgrade in the future with whatever setup you have, a turbo upgrade alone will cost you $2000+ with minimal supporting mods.

2001 is Hammer file, 2000 has the K05 and J31 files.


01svtL - for a bolt on FMIC kit the Racetec would work for the power your looking to make and cost around $800 + shipping.


To get 250-275hp your cheapest choice would be to do a GTRS elim kit on your stock manifold, 550cc injectors and REVO GTRS tune for that setup.

And that's flywheel or awhp? I would be looking for stock s4 power levels, which is what, 270?

[01svtL]

Or I guess even a little less would be fine sine the A4 probably weighs less being that the motor is smaller...

[onemoremile]

The S4 is 250 stock and 310 chipped. You still can't compare the power based on peak horsepower since the delivery from the twin turbo v6 is completely different. The weight difference is about 300-400 pounds. Because of it's torque I've found that an S4, especially a modified one, feels lighter when accelerating than a 1.8t.

[01svtL]

Hmmm. This is becoming a tougher choice by the minute. The A4 I am looking at is setup very well. Forgot to mention earlier that it also has a Borla catback, so could I potentially get more hp with a different (more agressive) tune than the APR stage 1?

The s4 I am looking at is a good deal too, but it needs some paint work on the rear bumper, and I don't know if I want to fork over the extra $2k for the car. I'm sure you guys think it would be worth it...

True but only when the cars are starting at low rpms, but if the car is being launched or going thru more then 1-2 gears that low rpm tq band is no longer being used. So the only people that would actually use it are those that worry about being below 3500 rpms. A Gt28rs or larger A4 is going to pull much harder from mid to high rpm then a modded K03 S4.

That's fine, I like low-end power better anyway!
