4.2 v8 or 2.7 bi turbo???
4.2 v8 or 2.7 bi turbo???

looks like i am changing from my rx8 soon 
love the car, can fit 4 ppl in easily, get a buggy in the boot etc but unfortunately i need to use car seats so its not really practical.
and as my eldest is moving out then the car will be getting used a lot more.
right so i am looking at changing my motor and the motor i am looking at isn't actually jap. (1st time in nearly 10 years i wont of had a jap motor)
now atm i aren't saying what i am looking at in case it falls through.
but basically there are 2 versions of this motor
1 is 2.7ltr bi turbo producing 261bhp as standard
the other is 4.2ltr producing 344bh as standard plus a whole lot more torque and the glorious v8 tone.
which is going to be easier to run in regards of running, tuning etc.
andwhich would ppl go for???

Audi s4's by any chance? One older shape, one newer shape?
The turbos easier to tune for power I'd guess.
But the v8 simpler to maintain I reckon.

Well I can't imagine either being economical but my mates got a bi turbo one and he loves it.

i am imaging around 18-20mpg??? which is what i get anyway.
i was meaning more towards servicing etc
I've never owned either of them so can't comment but any V8 will sound stunning easy engine I would think to work on out of the 2 but other than that I'm useless :laugh:
I fancy both tbh.
Twin turbo for the tuning potential
The v8 just for the noise and torque
