V8 RS6 Motor & Box

[MattYorke]

I'm sure I saw a while ago a thread and some pics of the 4.2 RS6 V8 motor joined up to a manual audi transaxle to go in an ultima.

Given that I now know this motor quite well, it seems like an interesting idea to put in my spyder - but I can't find the thread Can anyone point me at it - I've searched a fair bit and can't find it - I can only find one with a porsche box done @MRC or the V10 one.

Not the one I'm thinking of, unfortunately - it was definately a post on pistonheads.

Nope, sadly. That's with a G50 box - this was specifically with an audi box. Maybe I'm mistaken and it wasn't on pistonheads - thank you all for looking.

Thanks for all the replies.
This is the thread I was looking for - apologies, it was on an S6 motor, not on an RS6.

Really just wondering whether to chop in the G50 and SBC adaptors I've got to go all audi, or go audi motor & G50, G50/SBC or G50& LS something. Or even left field and leave the UN1 that's in it at the moment and just replace the motor.
Lots of options!

Historically, I'd totally agree with you. However with ECU controlled boost, this is a gamechanger IMVHO since you can fully control how and when the boost comes in. Even though the RS6 motor is a relative dinosaur (I'd describe it as the last evolution of "classic" tech), it has smallish turbos that come on boost quite early on and are pretty linear all the way up.

I love the idea of being able to dialin as much power as you like with the turbos but a turbo power delivery is not what I'd fancy in an ultima TBH.
