Even if the engines themselves are mostly the same, they will almost always use different turbos and belt-driven accessories. These two changes are done for packaging reasons the A4 and Passat are larger vehicles overall, so they have more space under the hood. On the Mk4 VW Golf, GTI, Jetta, New Beetle and Audi TT, the engine is mounted transverse, meaning the cylinders are in line between the strut towers. The Audi A4 and VW Passat are mounded longitudinal, meaning the cylinders are in line between the firewall and the radiator. The biggest difference depends on if the engine in your vehicle is mounded longitudinal (north-south in your engine bay) or transverse (east-west). There are many variants of the 1.8T with slight revisions over the course of several years, and each variant has its own 3-digit engine code, which can be find either on a label on the timing cover or stamped onto the engine itself. It was also the first vehicle to use the 20v 1.8T engine, which soon found its way to the rest of the VW/Audi line, and created a tuning platform that’s still popular today. Right? I'm done suffering over cars.What’s the last time you saw an Audi on the road older than a first-generation A4? The B5-chassis A4 was a turning point for the brand, and it’s probably the reason Audi is still around today. But, yeah, big power with none of the installation headaches and searching for just the right fitting, or waiting for it to be mailed at the last moment at great expense, etc, is what we all want. I understand your offering is not a rework, but I also suspect it doesn't bolt up to completely stock oil and coolant lines. The stock compressor housing also won't take a wheel with an inducer any bigger than, what, 50mm at best? Reworks are nice, but the tiny turbine wheel is a limiting factor, clipped or not. Maybe a K26 or K27 hybrid, if the fittings are the same. What I want, and I'm sure plenty of other people would like to see, is a turbo that bolts up exactly like stock but has bigger wheels on both ends and a bigger, stronger shaft in a BB CHRA. Also, is it an actual Garrett CHRA? Is it ball bearing? If so, isn't it essentially like the ATP GT2871R? Wouldn't a Garrett CHRA mean it would be the same PITA as the ATP to adapt to the stock fittings? I'm enjoying seeing another option on the market, but I have a few questions and comments.Ĭan you be more specific on what the specs on each stage turbo is? Like the turbine and compressor wheel specs, as well as the compressor housing A/R.
