Stigan New Turbocharger

Thank you for your inquiry. The standard turbo should be about 150hp in comparison to the high performance, which can produce up to 225hp.

Thank you for your inquiry. The turbocharger on this listing does not include gaskets. We do carry the turbocharger as part of a kit including the gaskets, which you can find by clicking on this link.

Thank you for your inquiry. The turbocharger on this listing derives from OEM and will have the same specifications as the unit originally installed on the following applications:

1996-2006 Audi A4 1.8L Engine
1998-2005 Volkswagen Passat 1.8L Engine

If you are wanting a unit with higher HP than OEM we recommend purchasing the Stigan high performance option within the same listing. The Stigan high performance is rated at 225hp.

We do stock the KO4 from Borg Warner but it is not listed on our website. Please contact our sales department at 888-907-7225 for a quote.

Yes this turbo is a K04.

Thanks for your question Mike. I can confirm that the mounting bolts and locking nuts do come with this Stigan turbocharger. If you would like to view them you can scroll through the images on the top of the page.

Yes, this fits all US-spec 1997-2006 A4 and 1998-2005 Passat 1.8T.

No, this turbo (40-30002) is for 1997-2006 Audi A4 and VW Passat 1.8T. We have the correct turbo for a 2006 GTI available here:

You don't necessarily need the syringe, but you do need to inject some oil into the center bearing of the turbo before you install it, and the syringe makes it a lot easier.

No, this is only for Audi A4 & VW Passat 1.8T models, which were turbocharged from the factory. If you're looking to add a turbo to your vehicle, you would also need an exhaust manifold, all the intake components (including the intercooler and vacuum parts), likely some larger fuel injectors, and a custom tune to make it all work reliably. This will also affect your vehicle's reliability, fuel economy and ability to pass any emissions testing. Flyin' Miata and Goodwin Racing both make turbo and supercharger kits for Miatas that are very well-regarded; that might be a good place to start your search.

Not at all; this is for models that were turbocharged from the factory. If you're looking to add a turbo to your vehicle, you would also need an exhaust manifold, all the intake components (including the intercooler and vacuum parts), likely some larger fuel injectors, and a custom tune to make it all work reliably. This will also affect your vehicle's reliability, fuel economy and ability to pass any emissions testing. If you'd like a faster car, it would be much easier and probably less expensive overall to simply trade in your vehicle for something faster.

The turbo and intercooler are two different parts, not a single assembly, but every vehicle that this turbo fits is also equipped with an intercooler, usually tucked right behind the bumper.

This turbo (40-30002 SG) is a stock replacement that's going to fit and function just like OEM. If you have a few other bolt-on mods, it shouldn't be an issue with this turbo, but we also have a K04 upgrade available here:

The K04 has a slightly larger compressor housing that can flow more air and create more power, while still retaining a response close to the OEM K03; none of the lag traditionally associated with a big turbo. If you need to replace your turbo anyway, it's not a huge price increase, and it's much better suited for the higher dyno numbers you're trying to get.

No, this turbo (40-30002) only fits the A4 and Passat 1.8T; the engine mounting is completely different in the Golf, Jetta, New Beetle and TT. Which engine code is your 1.8T? For model year 2003, the options are AUM, AWP, BEK, AGU or AUQ, and they each use a different turbocharger.
