Hi everyone i just throwing out a idea for you all maybe it will get done by me or one of you it is to install the VW Phaeton 6.0L W12 engine in a fiero as it is 20.1 inches long just about a inch longer than the Audi 4.2 V8 I installed so it should fit the engine has 444 horsepower . the engine is basically 2 VR6 engines put together i know if i get around to doing it it will have the 5hp19 automatic that i would rebuild and do the mods that are needed to strengthen it as it needs a clutch drum upgrade as one of them breaks . I hope this enthoses one of you to do this swap and you beat me to the punch

well i have been doing some homework on this and i feel physically installing the engine is not really any harder than the 4.2 Audi but the problems start when doing the engine management as they are using 2 ecus from what i can tell they are treating it as 2 VR6 engines with a common crankshaft so it will have to be figured out how exactly to do that with stand alone ecu's but i am sure it can be done just need to figure it all out

You're a do-er, Mark. You get a lot more done than 97% of people wanting to do swaps.

W8 Passat? pfft. You already know how I feel about it since trying to persuade you to spend your money instead of mine.

The questions that I have is what are you looking to achieve and why would you want a V12 engine? Even if you could fit it in, the engine management issues would be enormous.

Dennis i like the challenge of it more than anything because if it is easy i get bored with it fast and it is not a V12 as that would be to long it is like 2 VR6 engines with a common crank so it is much more compact

It's not an extreme project, IMO. It's worthy. Stretched or not. Once upon a time fuel injected engines were out of the realm of swappers and DIYers. It's an electronically managed engine, not so much different than others.
There's only one other swap that comes to mind as mind as interesting and it's the Tesla. Specifically the Tesla, not just an electric powered Fiero like others have done.

yesterday i started up the little brother to the W12 as i moved the passat with the W8 engine and i am hoping to pull that out of the car in the next few weeks but that engine is a easy install as it is so short at 16 inches long for a 8 cylinder and i will use a stock ecu it is just a matter if i do stick or automatic transmission i think the car will be a automatic as i do not plan on keeping it and selling it and automatics sell better

From what I understand, this is the same engine that's used in a Bentley. It's quite a mechanical marvel. Gear heads should enjoy this following video.

An aggressive project for sure. That is a very wide engine and when you add an adapter plate for the transmission it will probably be a tight fit in the engine compartment. If you get this swap to work, you deserve a prize!

This is what wrenching for car enthusiast is all about. When I started the 3.8sc swap in into my Porsche 911.. got some kickback but at the end of the day... they are just cars and we should have all the fun we can with them

A Longitudinal install changes the equation. I've seen the BMW V12 in an extended Fiero with a Lamboghinni body and it fit well.

well looks like the Olds 455 out of the jet boat might be sold for $1000 and i am sure the Passat W8 car will sell pretty fast so this project should have some funding soon and i have found a engine for $2300 all shipped

well i got hit with NH doing a kinda stay at home for 5 weeks only essential businesses can be open fortunately for me automotive repair is one that can stay open but i am not sure whose car i will be repairing since they won't be driving them as they are to stay home and very little will be open for them to go to so no breakage so i do not plan to have much going on so i must not spend money as i might need as i might not have enough cash flow to pay the bills
