Where to begin modding? HELP!

[Sobo]

Hey, I just recently acquired a 2001 Audi A4 Avant!

It's a 1.8T(red T), 5 speed, Quattro.

I've owned a modded car before, but this will be the first one I'm doing from the ground up. I need some advice!

1. I know to start with a chip. So far, the chips with the best performance I've seen are GIAC and APR. I plan on running 93 octane in my car, so which chip choice will give me the largest gain in Horse power at the wheels?

2. There are some other funky mods I've seen, such as the "green" coolant temp sensor. Should this also be upgraded? What exactly does this do? Are there any other minor parts I should upgrade that will help with boosting my horse and torque up?

3. What are some other mods I should do besides the obvious(Cat-back, HFC, intake, chip) to get my car running at about 245 horse? I'm not looking to go BT or increasing displacement. I'm not that mechanically inclined yet.

Thanks!

best stuff to do is chip, diverter, HFC with a 2.5 or 3" cat back, upgrade the turbo inlet pipe and boost gaude so you can keep an eye on things. intake is more for sound on the 1.8.

all the above is if you dont wana touch the turbo

[ILoveT]

But he is shooting for 245 HP... A chip won't quite get you there.

What they said....plus ebc, tt, exhaust manifold, injectors,....the list is endless. Once my setup is running I will try to dyno it. Im hoping 265HP with all my mods.

[Sobo]

A little less that 245 is fine....

I really don't want to be getting into changing the turbo. Not right away...

It's really not that big of a deal. Couple bolts here and there. A couple sprits of PB Blaster and you've got a new car. It's really not like going BT. Don't be scared.

i have Revo tune stage 1 on my 01 A4 and i am very happy, power comes in very smooth, more torque than Giac or APR.....first mods i did to my car was upgrade DV valve and FMI.
A good size FMI will give you noticeable gain specially in the heat

You have an 01, no need to go k04. It would be a waste as you our base hp is 170 compared to other B5 models which come 150 stock. If you get the GIAC-X chip, you would probably have ~15 less hp that if you go K04. But if you want that extra 15 or so horsepower with the k04, by all means go ahead. I just don't know if that extra 15 hp is justified for the extra $1500. Here is a good start to learn what you would like to do with your car.

And Dahlback is the best chip for the 01. Either that or GIAC X chip. Do a chip, HFC, and exhaust and you would maybe be around 230 hp (assumption).

[Sobo]

What FMIC do you have?

And How much does a K04 run?

[Squarrl]

I would and am just going GTRS eliminator with 550cc injectors and revo tune instead of k04.

http://www.awe-tuning.com/pages/shar...s&IL=GIACChips
GIAC 1.3bar Chip alone ~210chp

http://www.awe-tuning.com/pages/shar...rain&IL=AWEK04
K04 with moderate GIAC tune on stock smic ~235chp
K04 with GIAC Hammer File (FMIC required) should put you around the chp as the PC19 for the nDBW

The K04-15 turbo will not tamper boost off as quick as the palm sized K03s. The torque achieved from the k04 is immense.

You have an 01. If you are going to get a bigger turbo, then at least get a GT28r. It will be the same set up as the k04 and even still uses your stock exhaust manifold. And with the rising prices of the k04, the GT28r will be around the same price. Some places will even sell garrett GT2560 for less than the KKK k04. I have seen the GT28r sell for $900 at places while the k04 sell for $1,100. But still, expect to pay at least $900 for a k04 brand new.

[legionvr6]

k04 is around 800 new if i remember right

[Sobo]

Okay. Where can i get a Giac-X chip?

Also whats the difference between a flashloader and a normal ECU upgrade?

How can I tell if I own a 2001 or 2001.5?

[Squarrl]

I would check the ecu for a number

[Seerlah]

They can be found for $800, if you are lucky. But as I stated, here ya go. The prices of the k04 went up maybe 2 months ago and are in back order in many places.

One of the first things I learned with my car is a k04 is pointless (this referrs to only the 01 model). If you want 245 hp, get this and call it a day. It would cost you the same as the k04 and will yield you greater hp.

[Seerlah]

I think the M box is 2000 and the CH box is 2001.5 (don't quote me on this). But they are interchangable, unless chipped.

-You can run an M box ECU in a car that came with CH
-You can run a CH box ECU in a car that came with M
-You can run a CH chip in an M box ECU

-I was NOT able to run a M chip in a CH box ECU (limp mode)

1. I know to start with a chip. So far, the chips with the best performance I've seen are GIAC and Unitronic. I plan on running 93 octane in my car, so which chip choice will give me the largest gain in Horse power at the wheels?

Fixed Unitronic has Stage 1+ and Stage 2 tunes for 93 oct. I've been really happy with my Stg1+ on my 98.5.

Other than that, the basics are great, HFC/TP, Cat-back, clutch, FMIC, brakes,.... there's always options

and dont get the gt2x if you go bigger than a k04 then atleast go with a gtrs!! the gt2x is only oil cooled and gives you no room to improve! and a k04 just sucks its a waste of money ..

Watch yo self!



Dont say a ko4 sucks.

[baboom]

wow.. sorry i was chugging down some haterade before i posted.. im saying he wants 250 to the wheel and he woln't get that with a k04

[VTAudiA4]

Haha...I just gotta back up my sig. lol

But anyways.......
250HP = Yes
250WHP = No

on a K04. Then a GTRS like you said will get him to those numbers.

[biketsai]

The ECU box has nothing to do with the 2001 or 2001.5 dispute. Do you have the sport package?
Dont waste your time on a chip and just get a K04 for the power you are looking for.

I really just posted that kit to compare prices of a k04 to a Garrett fot the HP he is looking for with direct bolt on. If he gets the GTRS, then he will have to upgrade manifold also. Then he is stepping into BT territory. Which of course is the better route .

[baboom]

hey woln't have to upgrade the manifold if he goes with the gt28r.. but he will if he would go with the gt28rs..

maybe the k04 will do him just fine. there torquey as hell though

[djwimbo]

hey woln't have to upgrade the manifold if he goes with the gt28r.. but he will if he would go with the gt28rs..

any Non-Eliminator or K0x turbo will require the use of a different manifold.
The GT28R is basically a non-water cooled GT28RS. There's some minor differences. IIRC the 28R isn't ball bearing either.
Both turbos would need a T25 flanged manifold to be used either way.

[baboom]

o i thought we were talking elim, sorry.. just go with an elim.. good bang for the buck and easy as hell to install. i ripped everything out of my car in a night and finished the next morning.. and if money is a hassle then scope out the classified's..
