My Goal

[s4dc3]

im starting with 00 1.8 a4 Q manual @ 119k miles in very good condition, i am putting on a custom exhaust in a few days and according to my boost gauge my car is also chipped.

I would like to make about 300hp, and also have a decent amount of torque, i have read that a Ko4 would make good torque but isn't good for top end. what turbo along with supporting components would get me to my goal without breaking the bank and without damaging my car?? thanks in advance

Im assuming you are talking 300hp at the crank?
the k04-015 wont get there, the options are the gt2x, the new one uses water cooling now so its a prity good turbo, the frankenturbo f4h has just been dynoed on a b6 at 230awhp and 260ft/lbs on the uni stage 2+ tune and meth epic 45pg thread if you want a good read in the b6 forum, or the gtrs elim will easy get you there plus some.
if you meant 300awhp then its a another story, you are in the danger zone for rods, some get away with it some dont. a full frame gt2860r will do it, a gtrs might get there on a custom tune, a gt2871 or 2871 elim will get there on a tapp tune maybe on some of the uni ones. there are also 50trims etc that use journal bearings which are slightly kinder on the rods but spool a bit slower, or bullseye will build you prity much anything you want, a s256 will do it with some left over. the last option is the most expensive but really cool, forced performance will take a gt2860r or gt2871r and put a 68mm alloy compressor wheel on it along with some machine work and you get something that has gtrs spool with 2871 flow.

i dont know what the difference is between hp and awhp. i will be using the car most every weekend however it won't be my DD (4runner is for that). if possible i would like to stay away from rods but again i dont wana sacrifice my car.

[vortexjunkie]

you cant have your cake and eat it too.... you need to decide.. rods or no rods then you will know what kinda turbo market you are in...so that is where you start

well there are 2 (well more than but we will stick with the common ones) 'chp' is crank horse power, it is measured at the crank or the flywheel when the motor is being run in a lab. this is what is usually listed by car companies and some tuners like APR. it is not what is on the dyno plots you will see around here, here we go to a dyno and put our cars on it and run them usually for a full pull through 3rd gear. This is the 'awhp' or all wheel horse power. it is around 22% less than what is at the crank on our quattro cars. This awhp is lower due to 'drive train loss' eg friction etc in the drive train which must be overcome to tern the wheels but not the crank when it is not attached to anything (like chp) this can be effected by things like flywheel weight wheel weight etc. what gear you are in on the dyno will also effect it that is one of the reasons why it is standard to use 3rd. There is also 'fwhp' sometimes on here, this is front wheel hp, the front wheel drives have less drive train loss than the awds so they get about 7% more to the ground than the awd cars (I think its 7% more, someone correct me if im wrong) be careful looking at dynos and make sure it was on a awd if you have an awd to get an idea of what power it is putting down.
For a comparason of speeds:
Andrew puts down 250awhp to the ground on an APR stage 3 kit +some of his goodys (similar to a gtrs). he is a fairly good driver with a stage 4 southblend clutch and makes it to 60mph in 4.9 sec
as a general rule
k03s will make it in 7-8 sec
k04s in 6 ish
gtrs in 5ish
something like a gt2x or f4h with a good clutch and an OK driver (not a drag racer or anything just someone what knows how launch, change etc) should be mid 5 to 6sec to 60mph
stock the american b5 s4 was claimed to do it in 5.7 sec and the rs4 in 4.9 from memory (might be off by a couple 10ths)
hope that helps, have a look on here and audi/qauttro world for some peoples dynos then have a look at the vids of them on youtube to get an idea of how fast they are, remember things look slower in vids, getting to 60 in 5 might not look like much on a vid but you will still be in the back of you seat when you put your foot down. it is all comparative though, the BAT guys would probably laugh at that statement, its not fast compared to a stage 3 s4 but compeered to stock it is a big step up

I would go the APR stage 3 route. Seems to be very reliable and will put you in the ballpark of your HP rating.

i thought there was 12% drivetrain loss in the Quattro system... i could be wrong

OP: Don't expect 300AWHP without doing rods.
and to reach 300hp its going to cost you at least 3k if you do it right and buy new parts...you need a new turbo, exhaust, fmic, MAF, Injectors, Tune, etc.(I never trust used parts)

[MrPibb]

I'm pretty sure it's a 22% drivetrain loss for quattro. Atleast that's what I was told, one of the reasons it's so difficult to make huge horse power without reinforcing your drivetrain or upgrading it.

[pipe7284]

for quattro is 22% loss

[s4dc3]

lets say i am trying to obtain awhp and will eventually have to do the rods. would it be best to buy the supporting components like maf, fmic, injectors and what not before getting the turbo and rods? i will most likely not buy allll the parts at one time.

[MrPibb]

You can always upgrade your FMIC, injectors and other supporting mods without a bigger turbo, however there wont be really noticable diffrence till you drop a huge snail in there. Otherwise i mean that would be the way to go if you can't afford everything at once.
I mean unless you prefer your BT on the floor of your garage rather then under you bonet.

[s4dc3]

what about mounts and stabilizers? will i need to get all new ones as well?

[Dynamite]

300awhp will cost a lot more than 3k. Gaberossi was meaning 300chp, that will be around 3k
I think apr have a sale on atm for $4050 for there kit, that will get about 250awhp with some tweaking. apr is expensive though. you will also need a clutch, fx400 should do it, especially with a 240mm flywheel ($1000-1200 with the flywheel). if you want 300awhp then the best way to do it will be a full frame gt2871r on a 630cc of the shelf tune.
If it was me I would buy the mounts, rods, clutch, cambelt etc that is much easier to do with the engine out and do all of them, break the engine and clutch in on the k03 and then get the tune, injectors, bigger turbo etc later. If you dont want to risk blowing a rod through the block then you really should be doing them.

Did the 00 use the AEB rods or the awm ones? i cant remember
awm ones really wont put up with 300awhp

talk to jeff en psi
www.psiconcepts.com
He is working on some kits with TDO5 16G turbo and his manifold. I am actually purchasing this kit..
You should get the around the Hp and torque that you are looking for

[Dynamite]

Hmmm interesting, if you dont mind me asking, whats he charging for the kit? and whats it come with?
his 3071 kit for the b6 looks really good

[Papa Stone]

Dynamite, to be fair, I am a Beta version, I am one of his dealers, and is a hardware kit. I already bought injectors and they will be GIAC programing via Flashloader through your giac dealer. We will be developing the software in the next few months. Kind of letting the cat out of the bag.. but I am too exited to keep it quiet any longer..

SORRY for the thread hijack..

Ok fasho. seeing as how i do not have an extra $4,000 how many mounts do i need to replace?

[Gaberossi]

damn that much loss...hey at least im fwd on these flat roads ;)
