So you want to build your engine… A Complete Newb Writeup

http://www.audizine.com/forum/showthread.php?t=187836

With the Audi community slowly catching up to the VW community in terms of building engines and BT, I thought a good writeup would really help.

So you want to build your engine eh? That world of bigger turbos then the GTRS will be opened and the real fun times will begin. But where do you start? This will be a guide to what you will need from start to finish to have everything done right.

We will start out with the simple qestion, “I want to do rods, where do I start?”

Well, before ordering anything you need to know what type of rods you want. If you want to do just drop in rods with your stock pistons, with the 19mm wristpin (which is less safe than a 20mm wristpin, but can still take a beating), you have…

- Integrated Engineering Rods ($350)
- Pauter Rods ($800)

Now, if your ready to change your pistons out for bigger 20mm wristpin, you have a few more options.

- Carillo ($850-$1500)
- Scat ($350)
- Pauter ($750)
- IE ($330)
- Eurospec ($700)

Now, for those of you that decided to get pistons for this job way to go, you have a few options here as well.

- JE Pistons ($600)
- Mahle ($600)
- Wiseco ($600)
- OEM AEB Pistons (these come out of the 97-2000 A4s and have 20mm wristpins) ($100-$200)

Now, your rods (and pistons possibly) came in the mail and your all happy, however, youll need some more things to complete the transaction.

- rod bearings
- rear seal
- head bolts (or studs depending if you want to step up)
- head gasket
- timing belt kit
- pan sealant
- assembly lube
- pistons with rings or OEM rings if using stock pistons

Cool, your all set. Now, you want to make sure you have the tools for the whole job. Tools you will need are

- Torx Set
- Hex Set
- Metric Socket set
- Torque Wrench
- Ring Compressor
- Ring filers

——————————————————————————————————————————–

So F that 1.8T stuff man, your moving on to bigger and better things. You’re tired of this 1.8 stuff and your doing something about it. This is when the B5/B6 split becomes more apparent.

We will start off with the difference between the B5 and B6 1.8T engines.

In 1997, Audi introduced the AEB 1.8T, arguably the best 1.8T ever made. It had a free flowing head and strong bottom end (20mm wristpin) with forged internals. In the year 2000 this free flowing head was replaced with a small port head but kept the strong bottom end until it was replaced in 2001 by the weaker bottom end. In 2002, Audi came out with the AMB, basically a different block design altogether but with the same weaker bottom end and small port head.

Earlier Block Model – 058
Later Block Number – 06A

I will be using 058 and 06A a lot so stay focused here.

Now onto actual displacements. Engine builders round up quite often, which you will see here. Things to note here is that the stock bore is 81mm and the stock stroke is 86.4mm

86.4mm stroke = Stock 1.8T Cranks
92.8mm stroke = AEG/ABA Cranks
95.5mm stroke = TDI Crank

81mm bore x 86.4mm stroke = 1781cc
83mm bore x 86.4mm stroke = 1870cc
83.5mm bore x 86.4mm stroke = 1892.7cc
81mm bore x 92.8mm stroke = 1913cc
83mm bore x 92.8mm stroke = 2008cc
83.5mm bore x 92.8mm stroke = 2033cc
83mm bore x 95.5mm stroke = 2066cc

It is possible to do more but if your going that big you need more info then this thread…

Now, for your custom pistons for this job, you have a few options here as well, just make sure you order them in time they usually take a month to make! Also, you can get many different Compression Ratios, I went with a 9:1 but talk to them about what you want, everyone’s needs are different.

- JE Pistons
- Supertech
- Wiseco

——————————————————————————————————————————–

If you have an 058 block, I’m going to assume your doing the bold route (2008cc) because it is easiest. Now, your basically pulling your whole engine apart to do this so it is much more detailed. Basically you just need one more part, the crank, so now you have

- Pistons
- Rods
- Crank (058 guys use the ABA crank for 2.0 builds)

“You will need to shave the walls on the inside of the block to make the 92.8mm crank with Scat rods work. Cyl #1 has to be shaved the most, then shave the inner reinforcement of #3 and the lower reinforcement of #3. No need to shave the wall on 4th cyl wall but the piston will hit the oil squirter. Answer: Run a copper shim to move the squirter up so it’ll clear the piston squirt.” – Paul@BF

A machined intermediate shaft is needed for everything to fit also. Check Paul’s thread for more info (listed at the bottom)

If you have an 06A block, I’m going to assume your doing the bold route (2008cc) because it is easiest (and even easier then 058 guys). Now, your basically pulling your whole engine apart to do this so it is much more detailed. Basically you just need one more part, the crank, so now you have

- Pistons
- Rods
- Crank (06A guys use the AEG crank a crank out of the new 2.0T FSI motors)

Now, because your motor is comming completely apart, you will most likely have more things to replace, keep in mind some of these may not be needed for you and some may be. Its all up to you. I would get some more opinions with your milage and such.

- crank bolt
- main bolts
- main bearings
- rod bearings
- rear seal
- head bolts (or studs depending on what you want to do)
- head gasket
- timing belt kit
- pan sealant
- assembly lube
- oil pump

Now, for the main bearings, there is a big controversy of which color is best. There are colors on the top bearings (the ones that sit on the top of the crank) that determine their crush factor apparently. Anyway, on the bottom of your block it should have letters, 5 of them, in a row. They should tell you what color your bearings are. Keep in mind that the letters are in German. Mine were Red (Rosen in German) so my block looked like this – RRRRR.

——————————————————————————————————————————–

Ok so you’ve gotten all your parts (although you know youll be at the dealer for those last minute things you break!), good. Now your off to find a machine shop.

WARNING

by this point I would assume that your ready to tear apart your motor. I would get a spare 06A block for myself (they float around Vortex a lot) and build that. My car was down for way too long and it sucked I could have saved myself a lot of trouble by having a spare block!

Ok so for the machine shop, you need to make sure they have done 1.8Ts that work before. Seriously make sure you have talked to someone with a running engine from their shop. Bring at the least your pistons to them, your going to want a

- 83mm Bore/Hone
- Hottank

and you can get whatever other options you want but its all up to you. I got the block decked also and the assembly balanced, but it doesnt matter because I think I mixed up 2 bearings, o well shit happens.

I paid $400 in all (crazy good deal) but the pricing gets way up there depending on the shop/amount of work

——————————————————————————————————————————–

Well, I cant really help you out on this part, it would be the assembly. Make sure if you dont know what your doing that you have someone help you who does or you leave it to professionals. Basically the hardest parts are torquing everything down, ring gapping (I snapped one of my rings in the process ), and getting timing right once the head is on.

Hope you all enjoyed this thread, let me know if you want to add anything else.

Thermostat Replacement B5 AWM Engine Code

Could relate to other model years but do at your own risk!

First off this is not a very difficult job if I had to rate in on a scale of 1-10 I’d give it a 6 only because you are working in a tight spot with not a lot of light.Tools:

10mm Socket
13mm Socket

T40 Socket
T30 Socket
6MM Hex Socket

Swivel Head
Extensions
Flathead Screwdriver
Pliers
Flashlight

and your best friend a Craftsman magnet pen.

First I drained the coolant from the radiator, on the driverside there is a little red plastic screw you can use a philipshead screwdriver to loosen it up. (you don’t have to do this, I need a coolant flush so that is why I did it)

Next I removed the coolant reservoir. pretty easy there is three screws holding it down and one sensor on the bottom. You will need to undo the hoses as well.

Next take off the throttle body and intake hose

After the throttle body is off and out of the way you will find this engine brace. Take it off unless you can contort your arms and hands and work around it

your engine bay should look like this

This is the guy you are looking for. Now it is a little tricky but you can work around the alternator. You may want to disconnect the ground wire on the back to make it a little easier, just wrap the wire in electrical tape so you don’t make sparks…like I did.

The bolts holding the t-stat housing are circle in red and the ground wire is circled in green. If you can work around the ground wire do it. For me it was easier to remove it.

After you get the housing off just pop out the t-stat. BE CAREFUL! make sure you have a bucket or something under your car coolant will come out like a waterfall! I made the mistake of putting the rubber o-ring on first then the t-stat. when I closed everything back up she was leaking like crazy. So I had to pull everything off and put the t-stat in first then the o-ring. You will see that the t-stat should sit inside the engine block and not move. The way I had it the first time made it difficult to put the housing back on, I don’t even know how I got it on the first time.

Heather Lutze pours out her knowledge of how to be found on the Internet in the book The Findability Formula. This unique formula is Lutze’s guide to search engine marketing. Heather has ten years of management experience in the field and is the owner of Lutze Consulting. The findability Formula is a step-by-step guide to how to maximize a company’s pay-per-click marketing. It also is a guide to search engine optimization.

In the first part of the book Lutze starts out with the basic aspects of search engine optimization. She explains some basic definitions like what exactly findability is. Then Heather goes into what search engines are and how they operate. The difference between a natural search and paid placement is gone over in detail. She wants to make sure that the reader really knows what the difference between the two is. Google, Yahoo!, and MSN are all covered as well.

The next couple of chapters dive into what exactly a person needs to do before they start their online marketing. Good clicks and bad clicks are differentiated. Then the meat of what Lutze’s book is hit. How people search and what they search for is laid out. She explains what her take on the average persons “buying cycle’ is. And it is pretty basic and makes perfect since. There are three stages according to Heather and they are the information, shopping and purchasing stages.

In the fourth chapter Lutze gets into the finer aspects of what she means. She starts off with the “keyword trail”. In this chapter, like the book, she has the reader think in the big picture and then narrows it down. She wants the reader to think about what they would type into a search engine to find their product. If the reader sells Nike Air Jordans then they don’t want to pay for bees wax as a keyword. Shoes are even too broad for Lutze. Heather explains that the keywords get more expensive the broader the keyword and with less turnover rate. She suggests using the keyword Nike Air Jordans, because it is narrow and will cost less with a bonus of a high turnover rate.

Throughout the chapters Lutze is constantly tying her three stages of purchasing into the book. The three stages of information, shopping and purchasing require three very different ways to go about the keywords. The information stage is the stage where broad words are needed. This stage is where the customer is just gathering information about what product they want and the perks and flaws it has. The shopping stage is where the customer will use about three words and it is a little more specific, like Nike Air Jordans. The customer knows what they want and are just looking around for the best price or service. Then in the purchasing stage the customer has their credit card out and is just looking for exactly what they want, at what price and what service they want with it.

Lutze goes into a lot of detail about what exactly the reader can do to get the most out of the three stages. She dives into geographic modifiers, time restraints, how to get the most out the keywords and what to do after the marketing is up and going. Heather even goes into step-by-step ways of how to do things on her favorite web site.

I thought that this book was a great starter. Lutze goes into great detail and takes the reader through the whole process. It was nice that she didn’t assume that the reader knew anything. She also did a great job of explaining exactly why she is telling you to do something. Her main goal is to let the reader have a good overview so they can do it themselves or at least have a good idea so that they can have input into their search engine campaign. Lutze also emphasizes knowing your customer and what they are going through.

The only downside of the book is that it is a little repetitious. She will explain things over and over a bit to remind you how the aspect is relevant to the new subject. But this is the pain that is minimal and bearable to learn Lutze’s style. But all and all a good book that I recommend for beginners.
