I have a 2.slow 2001 beetle and was wondering if I could buy a wrecked Audi TT and part it out and install everything into my bug. If there are things that wouldn't fit, what would they be?

Front end is doable: Audi TT-VW Golf R32 spindle and lower control arm conversion-mk4 | VW TDI forum, Audi, Porsche, and Chevy Cruze diesel forum

As for the AWD/Halidex system; it has been done before but is a major undertaking. These guys have done a full RSi conversion with a twin turbo VR6; pretty amazing stuff.

HPA Motorsports, Inc. | Proven Performance Parts for Volkswagen and Audi

As for cost; I would just save your money and sell your 2.0L and buy a Turbo S New Beetle (1.8 Turbo 180 HP and 02M six speed transmission). We have been seeing some sell; for as cheap as $3k/$2500 lately. This would be the best platform; to start building a performance New Beetle; in its stock form, it is a pretty quick car and tuning is easy, parts are plentiful.

At the end of the day; I question, spending all the time and effort on a 2.0L New Beetle. Buying another one with 1.8T; is the way to go and so many are being sold for dirt cheap right now, its pretty amazing.

As far as the 2.0 that's what i have(1998 NB) and i think its pretty quick now. If you want nothing but nose bleed performance, gut the whole thing, add a tube chassis, and drop in a V8 and have at it.

Well the cost isn't really a problem for me. My bug is yellow and the city I live in is full of prepared cars and I was to have the whole sleeper thing going on. The v8 seems a bit extreme at the moment but I'll look into the Audi TT parts for sure. Thanks!

Depending on the year of TT you use, you may as well just put in a 1.8T from a beetle and get a tune for it. If you use a new TT well then that's just a crap shoot, it's probably safe to say that most things wouldn't cross over. But of course you could get an engine in with enough fabrication.

Or any other mk4. Find an AWP 1.8T, which has 180hp and you'll be pretty set. Plus, with a tune, its a nice setup. Its what I have in my GTI and I'm on Stage 2 Unitronic for a tune. Its plenty peppy to say the least

True, any MkIV will do :goodjob: If you don't go 1.8T throw in a VR6

I just did a VR6 swap on a '99 NB, and honestly, it really wasn't that big of a job. It took me two weeks of time... and all that was after working 8-5 every day. I started with a running/driving 2000 Jetta, and a running/driving '99 Beetle.

The biggest time consumer was waiting to get my ECU back from the tuner who disabled the immobilizer! And the gas pedal install was a pain because the Beetle had a mechanical throttle cable, and the Jetta was throttle by wire... the gas pedal mounts are different, but I didn't feel like removing all of the pedals/dash support and stuff so I just drilled the spot welds out of the pedal mount from the Jetta and put it in the Beetle (plus throttle pedal wiring.)

The Audi TT swap is definitely doable. Many people have done it, and there is some evidence of it on the internet. No one has come forward with a full write up yet, but it is possible. The AWD system from the TT will fit, provided you swap out the spare tire wells and the gas tank. I'm pretty sure that the Mk-IV Bug and first gen TTs even have the same wheelbase and width. You have to remember that a TT is basically a MK-IV car (99-04 only). Its a more expensive, all wheel drive beetle essentially if you really look at it. The engines, while having different codes and slightly different internals, are the same between the NB and the TT. Same with the transmissions. If you manage to get an entire TT driveline and you are decent with a welder, this is definitely something you can do yourself. I have done a lot of research on this, as it is something I have planned for my bug, and I know for a fact it is doable to the person who is willing to put the effort forth. My hang up is tuning the darn thing, however. Do I use the TT ECU or go standalone? Thats the only area I am uncertain about. I've never been good with programming computers or anything like that, so thats my shady area of expertise.

Perhaps if you do it/I do it wwe could work together to write the first DIY on this topic. I know a lot of people have looked for it, and the people who have done it have been tight lipped on how they did it.

Bandi, I had a couple of questions for you about your VR6 swap:

1. the 2000 Jetta - VR6 2.8 12V I assume?
2. You used the engine wire harness from the Jetta?
3. All of your Beetle gauges, etc still work as normal?
4. The immobilizer I assume is part that comes with the Jetta?
5. I have seen replacement VR6 mounts for Jetta/Beetle, I presume you just got something like that or used the Jetta donor car ones?
6. Other than the gas pedal, any other custom fab work, or was the rest bolt-in?

Thank you, I am still trying to get my arms around the VR6 swap issue. I'm an engineer, so I am trying to get all the little details worked out before I even start looking for parts.
