New A4 Owner, need lots of help (also in general tech)
About a month ago I bought a 1999.5 A4 Avant quattro 1.8t 5-speed. I know plenty about cars and have been working on cars since before I could drive, but I know nothing about Audis and this is my first turbo engine (ok, I did own a 2001.5 Passat turbo, but I never did any work to that car and traded it in in less than a year). I understand how turbos work, and have researched them a lot (thought about boosting a couple cars I use to own).
Anyway, my A4 came modded, and from the owner I got this:
So first off I have questions about my mods. A friend of mine who did service writing for 2 Audi dealerships confirmed that there was some well thought out work done to the car, but I know nothing about this stuff.
So please, some comments/explanations on the items/work stated above would be great. Pros and cons.
Also the car came with some work needing to be done, here's what the seller offered:
The car does run cold, I don't think I've seen the temperature gauge reach the mid point. Should I replace the thermostat? Do they offer different temperature thermostats? Where is the stat and how much trouble is it to change?
Someone is giving me a front mount intercooler, will this block the radiator enough that I might appreciate the cooler temperature? Is there anything special about the "race products" side mount on the car?
I feel the throttle cut on the car, but it only seems to happen when the car is boosting slower, when I really get on the car, I don't experience the throttle cut. I don't know what a throttle cut defender is, I think I heard it was cheaper and easier to install than a manual boost controller. Can someone explain this?
Those issues came with the car, I've made my own issues since I got it.
The driver side wiper quit working, the passenger side still works. I've checked the the wiper arm is tight on the shaft, but you can move the wiper freely by hand (shaft turns too). Is there a linkage from the passenger side that could have come loose? A parts guy told me that the linkage assembly is part of the motor assembly and not available separately. Of course I haven't even opened up the cowl to see what happened yet. Any ideas?
I broke my hood latch release (behind grille). I didn't realize that the latch needed lubricant and it was tight, I pulled the little latch that comes out of the grille and broke the plastic piece off the end of it. I can still get my hood open, but I'd like to replace the latch, does anyone have one for sale? I can get a whole new latch from a parts guy for about $40-$44, but that's the type thing I figure I could find a lot cheaper off a hood someone is parting out.
Guys, any help on this stuff would be greatly appreciated! TIA
BTW- Forgot a couple things. I have a boost leak, I can hear it when driving in boost. How can I hear it (and therefore find it) with the car running parked?
A friend gave me a new ApexI turbo timer, any install tips would be great.
Anyway, my A4 came modded, and from the owner I got this:
Mika tuned GT 25 software
RS2 - green top injectors
K24 sport turbo
Race Products intercooler ( side mount )
ECS race N75 valve
new spark plugs
VR6 Mass Airflow housing with open air element
MTM cast exhaust manifold (costs $2000+)
URS4 external wastegate
Audi TT 225 hp by-pass valve
Custom fabricated 3" exhaust ( cat delete ) - ( NO Check Engine light )
APR Snub mount
Eibach sport lower springs
RS2 - green top injectors
K24 sport turbo
Race Products intercooler ( side mount )
ECS race N75 valve
new spark plugs
VR6 Mass Airflow housing with open air element
MTM cast exhaust manifold (costs $2000+)
URS4 external wastegate

So please, some comments/explanations on the items/work stated above would be great. Pros and cons.
Also the car came with some work needing to be done, here's what the seller offered:
Timing belt, water pump, seals, thermostat just done along with MAF/throttle body cleaning, new plugs.
Could use some additional tuning. Runs cold (about 40%), probably needs a thermostat, replaced it once, maybe got a bad one. Runs rich, probably related to the engine temp, cat delete, intake piping (MAF) or chip programming. Experiencing some throttle cut on boost, possibly solved by a manual boost controller or throttle cut defender, adjustment of wastegate or new diverter valve. In any case, all fairly easily addressed issues. Very fast and fun, probably running at 250-300hp.

what do you mean block the radiator? it cools the hot air coming from the turbo before it gets to the cylinders. but yes a front mount will typically work better than a smic depending on the density of the core. i've never heard of that smic you have

pour soapy water on the engine, smoke test it, or http://audizine.com/forum/showthread.php?t=104080 or http://audizine.com/forum/showthread.php?t=64411

Your picture helps, I heard the thermostat was easy, so I'll tackle this soon.

Any recommendations on tuning, keeping in mind I'm cheap?
Any recommendations on tuning, keeping in mind I'm cheap?
I have heard from people before that have added a FMIC that it physically blocked some air flow to the radiator, and they had to upgrade their cooling system, I guess I'll worry about that when I install the intercooler.
Thanks for the advice, very helpful. I have some work to do, but the car is great, very dependable, very quick. I just have a lot of learning, which is typical with me and any car I get, you never forget though. When I was 17 I got into 5.0 Mustangs, had a couple, learned everything there was to know about those cars, still know them. In college I started looking into off-roading with Suzuki Samurais, got one, still have it, have replaced everything and know them inside and out, top side and bottom side, even when the bottom side is not on the bottom anymore. Oops. I got into Hondas in my 20s, had a CRX with JDM DOHC ZC, learned alot, studied turbo systems thinking of boosting it, still know a lot of Honda stuff. Needed a back seat and tired of FWD I bought a 240SX (before the drift craze) and learned all about those cars, it was a good one. Now in my 30s, I figure I'd go Audi. Give me time.

dont know since i've never heard of the turbo either. i would try emailing, GIAC, Unitronics, and TappAuto (Eurodyne), to see if they have tuning available for your setup.

Here's afew pictures:
Should there be a vaccuum line on that wastegate? What is that blocked off tube from the top back side of the turbo pipe?
This is the XS Engineering FMIC I have for sale. (lamb not included)

The previous owner said the turbo is an S4 turbo, K24? I'm pretty sure that's what he said. Said the computer was for a K25. Helpful?

im trying to figure out that little clusterfvck you got going on there lol the wastegate is throwin me off, i've never seen it setup like that. where is that pipe coming off the wastegate going? does it fuse into the downpipe?
the fmic looks good tho

It mentions K24/K26/K27 turbos... what are these turbos? Audi? Aftermarket?
