Ok so I am posting this is the s4 forum too.

I currently own a 2000 B5 A4 and am thinking about buying a new Audi.

The problem is I can't decide. B5 S4 or B6 A4.

I definitely want to upgrade on performance and the S4 is the instant winner.

but everything considered what would be the "best" choice.

 

Heck there is a guy that drops 2.7TT into A4 and Passat for around 3,300. Also do you want that new car feeling? I posted the same question last night....just the S4 are very tight to work on. If a turbo goes they have to pull the motor out to replace...but then that just makes you want a Ko4 or garret 32 (sp?). What the budget look like and why do you want to trade in?

 

I was thinking anywhere between 15-20k.
My current A4 has almost 150,000 miles and so I just want to get rid of it while I can get something for it.
Plus you can never go wrong with an upgrade.
Who drops those engines and where?? Also how do they run??

 

Its a shop out of TX and they rebuild the 2.7T and install it. Thats with the wiring and program for the set-up too, Was thinking it, but not ready to play with all that yet (still want a house...lol.) This is my POV, but Keep the car! You can't beat having two and then you could play around with the old B5 and drive the new OEM and keep it that way.

You could drop a 2.7T or just get a nice APR K04 program too.

Also is it a 1.8T? thats not bad for that motor...you toke good care of it. If it is a V6 then keep it for the 2.8L has been known for 300K plus.

 

Bull. There is NO way thats even remotely feasible. Give me evidence considering this swap into a b6 a4 has been done ONCE on record and it was by ABT.

 

Never said B6....he has a B5 now. Yes it can, has and will be done for that (in a B5 frame and platform). I was thinking SC my 2.8L for around 4K, another member said don't waste an extra $$$ drop the 2.7T into. He gave me the name of the guy...but the post has been gone a few months ago. I have PM'ed him for the details for the member asking for the info.

Yes you could not in a B6...to different....getting the car to talk with each other would be a nightmare.

 

I just told you it can be done, it HAS been done. But certainly for for 3300 .

B5 swap is of cake it's the same car different harness and your golden. Having said that! Even a swap into a B5 is not feasible for 3300 IMO. The engine and tranny etc would be more than that. Maybe 3300 in labor but that can't include parts.

If it WAS 3300 for a complete swap then noone would bother going Big turbo on a B5 they'd simply do a s4 engine swap. It'd be WAY cheaper than BT with supporting mods at that point.

 

This is just for a stock 2.7T which you u can get it from shokan. unfortunately, i'm unsure of condition, though if it was being rebuilt, i would have all of the parts professionally inspected by a certifiable high quality machine shop (heads and case).
as for programming, finding the proper program would just be a pain in the *** after pain again, so i would run with a standalone engine monitor system that uses all of the engine's existing probes to monitor everything so there's not need for a massive revamp of the entire vehicle. plus, you can "chip" the car to whatever you want.
drop in a new turbo? no problem! just correct the maps!

i've really gone to an extensive length to plan this out.

and technically, under the EPA's engine swapping guidelines it would be feesable and legal to swap the 2.7tt engine into the B5 passat under the guidelines that the engine was certified for that chassis, and is the sistercar of the passat, similar to what ford Lincoln and mercury do.

this is really a good read as to engine swapping guidelines. though if you're a mechanic, you can likely get the sticker regardless.....

when i eventually do this, should i build the monetary backing, i have a mechanic, billy of dubsquared in Pittsburgh, who has gotten the standalone down to a perfected science. he's really a skilled guy, and knows what he's doing. he could get it working no doubt.

of course, all of the mechanic grunt work i would do myself, such as the rebuilding, and engine installation, the only thing i would have billy for would be as a proof-checker, to make sure that the engine is in all proper order so it doesn't grenade itself.

Can be had for around 3300..more if your modding the crap out of it, but stock setup yes.

 

I was wrong and dan is right....I forgot (it was a few moths ago) but it was 4K ish for the SC..but one could get the motor and parts for 3K ish and DIY...which is what I wanted. I posted above how I would do it and another guy out of texas started doing them on the side (he told me 3,300.00 if I drove down and helped). We talked about it for a while...but you shouldn't have to change the tranny?

 

of course you'd need a tranny too. A4 is 5spd manual, s4 is a 6spd manual. not to mention the gear ratio is completely different to cope with the diff power band.

Why bother going stand alone? Use the ECU of the car that the engine and wiring harness came out of and your problem is solved.
