Which 1.8t do i have

Watch the video below for more information on how to identify you 1. Like most other VAG 4 cylinder engines, the 1. There are 4 outer main caps and one center main cap that contains crankshaft thrust bearings also commonly called thrust washers. The stock main caps are cast iron and can be upgraded to IE's billet steel versions as power output increases. All 1. Cranks found in the 06A can be found forged or cast iron. Most crankshafts are cast iron. The timing belt drive gear and crankshaft damper is attached via a 4 bolt interface.

Also on the crankshaft is the trigger wheel which is used in part with the crank sensor to determine engine RPM. With the common measurements out of the way, that leaves the wrist pin size, which vary depending on engine codes.

Most 06A 1. Some 1. Some engine codes did have forged pistons but they are not designed for high power levels, and still not as robust as forged aftermarket pistons. All stock 1. This section will be separated by different horsepower levels.

Our goal is to point you in the right direction and make your build a success. This proven combination works fine as long as the piston skirts and cylinder walls are in good shape. In high mileage or worn blocks, larger bore aftermarket pistons should be used so piston-to-wall clearances can be set correctly. It is fairly common knowledge at this point that 1. Two main factory connecting rod weaknesses:.

Very narrow beam design that leads to bent rods under increased torque. There are two possible solutions if you are planning on using upgraded rods with stock pistons connecting rod options: 06A blocks will typically require x19mm connecting rods that have a tapered wrist pin with the exception of hp engines. Rifle drilling is an oiling hole that travels the length of the connecting rod beam from the big end to the small end of the connecting rod.

Additional pin oiling has been shown to greatly extend bushing life on daily driven or high mileage applications. At these power levels the stock hardware, such as main bolts, are adequate. One important fact that enthusiasts often overlook however is that many stock bolts are stretch bolts and thus are one-time use only. Common OE bottom end hardware that are one time use and should be replaced are:. To ensure reliable operation at power levels exceeding HP upgrading to aftermarket pistons and rods is absolutely necessary.

Explore pistons JE pistons- a great option for street or track use, uses a tough alloy piston forging, with tons of compression ratios and bore sizes available. Explore pistons Wiseco pistons- a great option for street or track use, affordable yet good quality, uses a tough alloy piston forging. The 1. The most common failure point is the timing gear located on the snout of the crankshaft. As a solution, we have developed a crankshaft timing gear that is far stronger than the original unit and also an ARP crank bolt that increases the amount of force holding the gear on.

We highly recommend using a performance main bearing and rod bearing as power levels increase. The main advantage of performance bearings is due to a tri-metal composition they are able to withstand added bearing loads and are better suited to withstand crankshaft flex. At this power level, the stock hardware is typically sufficient as long as it is never reused. AEB: On the very back of the head, you'll find the cam chain tensioner.

If it has a solenoid with an electrical connector, it is an AWM. Here is a picture of the tensioner with VVT for the hp AWM notice the black cylinder with the electrical connector : Here it is installed on the car in the yellow box, you can see the electrical connector on the very end of the black solenoid : Here is a close-up in the yellow box, notice the black cylinder : Here is a pic of the non-VVT tensioner for the hp AEB and ATW: And here it is installed on the car notice the lack of the black cylinder : Both of the AWM and ATW engines are drive-by-wire no throttle cable.

If it has a throttle cable, it is the hp AEB. The above picture shows the throttle cable circled in red - making that an AEB engine. There is a bunch of other differences. I have a beautiful 99 a4 1. Probably the easiest way to tell is the cam chain tensioner on the back of the head You can check without removing any covers.

My Photo Gallery: Originally Posted by ghost BTW there is a difference between early and late model AEB engines, the way to tell is the early block has an intermediate shaft to drive the oil pump and the later 06A block doesnt.

Looking for the VVT solenoid just requires popping the hood. Also, if the engine has been replaced, the head code may not necessarily match up. Could be using a VW head or something. I agree, its not much work to pull off the cover, but the OP did ask for something even easier. My Photo Gallery: 2. Like i said not a big thing just curious is all as i wont be modding for a few months due to school debt and i don't know why i put ive done enough research to know that.

Anyways learning a lot and hope to have my own build thread up here soon enough. Originally Posted by CrtchRktRcr.

Michael Ghia , Nov 4, Lee-GTi , Nov 12, Thanks Lee, I'll look into the inlet manifold idea Seizure, I've just crossed referenced the AMK pistons and head with the BAM and they are the same so I'm presuming that the compression ratio will also be the same at 9.

Thanks for that. Michael Ghia , Nov 12, Mouse, thanks for the pics. How's the spreadsheet coming Michael? Chris H , Nov 15, Michael Ghia , Nov 16, Here's the latest list. I have had a quick look at Etos and it'll take a while to get used to.

Its very different to Etka! Michael Ghia , Nov 17, You must log in or sign up to reply here. Show Ignored Content. Share This Page Tweet. Your name or email address: Do you already have an account? No, create an account now.
