S4 4.2 V8-engine in A4

**martins** · 08-08-2005 10:33 AM

Hi...

Does anyone know if it's possible to put the 4.2 V8-engine from the S4 (B6) in an A4 (1.8T Quattro)?

Thanks,
Martin.

yeah not too long ago a guy posted pics of that motor he bought for 10 grand, and Im pretty sure he was putting it in his B6

why not trade up for an S4? by the time you procure a motor, and pay labor to get it installed, i can't imagine an S4 would be much more money

**madrussian** · 08-08-2005 10:48 AM

yes, its possible.

a great shop that does it is called the audi dealership.

should cost you about 50k, comes w/ other goodies too!!! ;)

**xonetruthcrewx** · 08-08-2005 10:49 AM

Yeah, unless you get a really good deal on the S4 motor. tranny, ecu and all that shit i would say just trade in for an S4. There are so many more things to an S4 than just the motor.

not worth it . . .

**400HPA4** · 08-08-2005 10:55 AM

Kinda pointless...you can make more power and torque with a 1.8t.

The 10-12 grand it would cost you could build an incredible 1.8t.

A new S4 here in Denmark costs about $ 215.000,- (we have alomst 200% tax on cars

)

If the engine fits in my car we'll install it ourself.

I have 300bhp in my 1.8T now (150bhp standard) . I keep upgrading stuff that breakes all the time.

I can get a allmost new (3.700 km) s4 engine with everything needed for $7.000,-

**pandaxprss** · 08-08-2005 12:43 PM

very point less if u want to do that i say sell your A4 and buy a S4

read.

Denmark has almost 200% tax on cars.

**duffS4** · 08-08-2005 01:11 PM

how about dropping a 2.7t in there?

**angryswede** · 08-08-2005 01:16 PM

how about dropping a porsche GT3 engine in there?

that's my ulitimate plan.

**Feeesh** · 08-08-2005 01:19 PM

i'd take a gt2 engine over the gt3.

I like the V8 more...

**Itchy Foot** · 08-08-2005 01:36 PM

how about the new 2.0T?

I would swap in the B5 S4 engine...

**nadroj81** · 08-08-2005 01:39 PM

i bet it could be done. prolly just have to replace all the electronics as well. new ecu/dash cluster ect. Might need the help of a friendly audi dealer to reset/code some stuff? I am not sure.

**giago** · 08-08-2005 02:01 PM

I would get a 2.7TT also.

**HoRnYTuRbO** · 08-08-2005 02:23 PM

bore and stroke the v8 and add twin turbos

**400HPA4** · 08-08-2005 02:33 PM

I'm pretty sure you can make mad power on the 4.2 with Schrick cams, programming, and a free flowing exhaust. It is a shame the car weighs 3700 pounds.

I concur, well said, I think it's a waste of time and $ to transplant. I think the S4 actually weighs more like 3900 lbs.?

**AudiGuy666** · 08-08-2005 02:45 PM

UHH.
All Quattro's weigh too much ..

Actually the new RS4 weighs around 3600, not too shabby.

**400HPA4** · 08-08-2005 03:18 PM

Gotta love the Aluminum roof skin, hood and decklid

**German Driver** · 08-08-2005 03:25 PM

Hey Greg you got PM

**|Sandman|** · 08-08-2005 04:30 PM

I´d go with a 2.7TT also, thats my dream..

That was me, didn't mean to mislead anyone into thinking I was that ambitious!

**Mark** · 08-08-2005 04:50 PM

I'd go with a 5 cylinder 2.2T and a UrS4 or Rs2 6 speed tranny if I were to do an engine swap.

**chrissurfr** · 08-08-2005 06:24 PM

Good man! the 2.2T engine rocks...this car's got about 400 crank HP:

and it has a modified RS2 6-speed...good deal!

he already said that theres nearly 200% tax on cars in denmark, it would be exponentially cheaper to do an engine swap in his case, and i know they can do it because they've done quite a bit of crazy stuff to his car in the past from what i remember.

**roccocurci** · 08-08-2005 09:43 PM

man im not sure about engine swap... that shit would be so complicated with the electronics, and not to mention all the BS with quattro and shit, the car would never drive the way it's supposed to.

heres what you do

give eip tuning a call.... buy this

http://www.eiptuning.com/eip/18t20vcompleteengines.html

then have them build you the 2.1 motor with a gt2871r or gt3071r, run some probably 580cc injectors or so, and have somebody make custom software for it, giac, revo, etc. and you will be at a minimum of 400 wheel horsepower... and it wouldnt be all laggy as hell like if you just slapped a huge turbo on the 1.8 liter... and the pricetag... probably a total of 10grand....

to swap the S4 motor in would cost atleast 15k because its gonna be a lot more than just the motor you need to swap... plus the S4 motor would not have near as much horsepower...

**Krendor** · 08-09-2005 09:35 AM

does the s4 have a bigger rear diff , tranny, torsen, half-shafts and driveshaft than us?

**martins** · 08-27-2005 11:55 AM

Well guys... I bought the stuff... now we only have to do the swap!

I need some S4 (B6) brakes... can anybody help me?

**tonbon** · 08-27-2005 11:59 AM

holy crap you did it! your crazy and i love you for it!

**gohan** · 08-27-2005 12:14 PM

Martins is old skool, he can do anything.

**Bronze** · 08-27-2005 12:16 PM

Awesome. Congrats for having the "palle" to do it and ignore the comments on this thread. Let us know how things go. Do you have a target date for completion, other than as soon as possible?
