its good for a whole hell of a lot more than that... If i had that turbo and only made 340, i would kill myself.
Also, 4grand is not going to even buy the required components to run a gt35... let alone if you are paying for the labor, forget about it. I'm not trying to discourage you, but its just not possible. maybe an elim kit is better for you... when you say "330hp", does that mean you want 330crank or awhp?

Yeah actually I'm set on the garret GTRS eliminator kit. I have the 225Hp tt injectors but they have an $800 fuel injector/software package. Anybody know how many cc's the injectors are? I also noticed they have a gt2871r upgrade option. You guys have any clue as to how much more powerful this option is and how much slower it will spool than the GTRS? When I order my exhaust it should bolt right up to the eliminator series turbo,....right? Lastly, the GTRS(shown here-->) http://www.atpturbo.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ATP-VVW-151&Category_Code=VVWTK
is said to produce "up to 350Hp" Are better numbers easier to obtain and how would the gt2871r fare against the gtrs? Also would an after market intercooler be necessary or would the stock SMIC be sufficient?

K04- easiest and most reliable replacement turbo. It is a direct bolt on replacement. You don't need to replace anything but it is strongly recommended that you get new programming. The most popular is GIAC and with it you will also need a 5 bar FPR. GIAC also offers 3 aggressive files PC-16 for Pre '00, J31 for '00, and Hammer for '01. They are each different but all require an adjustable FPR, bigger injectors, fmic, and you will most likely need a new clutch soon after. If you have a B6 or B7 A4 the k04 is a pointless upgrade. You will only gain a 5-10 hp because of the k03s. It has a 1mm bigger wheel shaft, and more aggressively angled fins on the compressor wheel so it can hold more boost more efficiently. A big injector file for the k03 will put out almost the same numbers as a k04 setup. k04 will max out around 250hp
Elims- The cheapest and easiest BT setups, but produce the least power. They eliminate the need for a new exhaust manifold and testpipe like full turbo setups require. The gt2x is only oil-cooled and has a not so good reputation, but it is the cheapest. The gtrs is a good choice. Lots more power than a k03/k04 yet has very little lag. Another choice is the 71r Elim. It has the same housing as the gtrs but a larger comressor wheel. Because of this it has slightly more lag but produces a little more power in mid-range but will get choked out in the higher rpms due to the small exhaust housing. If i were gona get an elim I would get the gtrs. With each of the elims you will need bigger injectors, software, fmic or water/meth, and a clutch would be a good idea too. It's also recommended you get a braided oil return line cause the stock one is a pain to get it. GTRS will max out around 300hp. 2871r elim will max out between 350-400hp.
GT28RS- You will need to get a new exhaust manifold due to the different flange, the stock one would most likely crack and rob it horsepower anyways. You also need a new testpipe/cat or you could just get a new flange welded on. You will also need a 3" VR6 MAF, custom intake, 3" turbo inlet pipe, 2.75"-3" exhaust, FMIC, bigger injectors (660 or 440 usually depending on the software), walboro 225lph fuel pump, stage 3 or higher clutch, adjustable fpr, and oil and coolant lines. And new mounts (all of them engine, tranny, differential, snub),a bigger oil cooler, new suspension, and bigger brakes are good ideas as well but not required. Cost will vary depending on what you have done to your car already. For a stock A4 expect a shop to charge you 7 grand, if you can do it yourself it'll cost around 4 grand for everything. It will max out around 350hp.
T3S60- This turbo is very simular to the gt28rs but unlike the rs, it is a journal bearing turbo. It spools a little slower than the 28rs while making simular numbers. The cost of this turbo is also about 1/2 of the 28rs
GT2871R- Pretty much the same as the GT28RS only bigger. .64 A/R is the faster spooling one. It should be fully spooled ~3600RPM. The .86 A/R has a bit more lag, full boost right around 4KRPM, but it produces more top end power. With the .86 A/R you will need the same mods as the gt28rs, but with the .64 A/R you will need that plus new forged connecting rods if your planning on running it past 20psi. Most AEB guys go with Scat rods, and all others use Integrated Engineering rods w/ 19mm wrist pins (unless you swap in 20mm pistons). Some people dispute whether or not you need new rods with the .86 A/R but there are some guys using stock rods and haven't run into a problem...yet. And you'll also want a stage 4 clutch. 2871r will max out around 500hp
GT3071R- Bigger turbine than the 2871r. The .63 A/R spools ~4KRPM and produces more power than the 2871r .86 A/R. There is also a .82 A/R on the 3071r which hit full boost around 4500RPM. You'll want a stage 4 or 5 clutch and new rods for both these turbos. It will max out around 600hp.
GT3076R- Uses the gt30 turbine wheel and a 76mm compressor wheel and spools the same as a 3071 maybe 100rpms later. Also where the 3071r tops out at just over 400whp, this turbo is efficent enough to reach 500whp with a proper tune and upgrades. On pump and low boost (22-24psi), expect to see just ~400whp and mid 300tq depending on mods. Popular with guys who bore their engine out to 2.0L to put down sick numbers.
GT3082R/GT3040r- A combination of the gt30 turbine wheel and the same 82mm compressor wheel found on the gt35r and gt40r. It is a decent turbo that is capable of high 500whp and will spool between the 3076 and gt35r.
GT3582R- The big daddy turbo. Good for 700hp+ and 10 sec 1/4 miles. Spool is expected about 47-4800 on a .63. This turbo is known to surge on stock displacement so a anti surge housing is a good idea along with a AEB head and/or stroker engine.
T3/T4- Turbo's that use a t3 turbine and a t4 compressor. These come in so many sizes and variations its ridiculous. They can produce anywhere from 300 to 700+ hp depending on the turbo and your setup. The only one that really should be used is the 50trim. It is the most effient of the 50,57 and 60 trim turbos. Unlike the gt turbos, these use old technology with journal bearings. This gives the turbo slower spool but is more gradual. This also makes it easier on the rods to where higher hp numbers can be achieved on a stock engine. The only other drawback is that the turbo doesnt respool as fast as a dbb turbo. But on the brighter side, these turbos can be had for a mear $575-625 depending on where you shop. Also the lag can be decreased by using a .48 housing or a .63 housing for more top end. A 50trim will spool just past 4k and is capable of making 350whp on pump and over 400whp on race gas and proper mods.

Yes I have thourally inspected the newbie guide.........again and again. Ive done many hours of reasearch and the gt2871r elim. seems to be the most efficient and versatile turbo for the money, yet I think I will be looking for more once installed. Any suggestions for kits or the necessary components for the T3/t4 50trim, and/or the Gt2871r Elim? Since you don't recommend the ATP tuning who should I have flash my ECU? I already have the APR stage1+ chip, will this save me some money or will whoever I go with have to use their chip? I'm looking at $1600 for the Gt2871r Elim. kit, which also requires the high flow injectors for $250, and tuning for another $500 since none of the other companies I've called will use the APR chip that is already installed. If you have anly links for me to go to and buy the t3, or the 2871r in a kit, or at least a reasonable price? Also I like the more conservative exhaust you mentioned in the newbie guide. Who would you recommend I purchase my exhaust from since you are runing the techtonics system I'm interested in? To sum it up, I want my car to smoke srt-4's, s2000's, most mildly modified tuners and modified v-8s, yet it is still a lightly driven daily driver. You seem to know your ****, so tell me what to buy and ill get it.

i would never get a 71r elim. its a 400hp turbo with a 250hp flange on it. it doesn't flow correctly and you will have hella lag and a small powerband. so while technically you can push upwards of 350hp you will only ever see those numbers high in the rpms. the only elim worth getting IMO is the gtrs. it has little lag yet produces decent numbers, and isn't choking because of the flange. but that turbo isn't gona produce the numbers you want. for the numbers you want, your gona need to go to a full setup, not just an elim setup. you can choose either a t3t4 turbo which is a journal bearing, or a gt28rs, which is a ball bearing. the ball bearing turbo's spool faster but t3t4's are much cheaper and the lag isn't bad at all. just curious, but have you driven or ridin in a 1.8t with an elim kit on it? and compared it to a car with a full t25 garrett turbo on it? just checking, cause i have, and i don't quite agree with some of your points
both setups will be very similar. just look under gt28rs in the newbie guide for the complete parts list. as for software i would recommend unitronics. you meant REVO. this is B6 country![]()
