Fact of the matter is that this all boils down to is: real estate. Why don't you shut your mouth for 2 seconds and TAKE A LOOK at a Contour engine bay (w/duratec).
There's no fuggen room for two turbos plain and simple.For example, from the factory (and on the SF kit) the rear manifold goes between the R/H intermediate shaft and the block simply because there is not enough room between the firewall, steering rack, subframe and the engine block to do it any different. Thus putting a turbo there is basically impossible, short of notching the firewall and removing your steering rack and part or your subframe too, or maybe mounting it in the passenger seat! But I guess steering is overrated for most drag racers so - what the hell!
Secondly, lets ssay
somehow you fit a turbo for the rear bank back there (and lack of airflow doesn't kill it in the process). No you want (by your theories) to mount the front bank turbo, about the same distance away from the front banks exhaust ports, as the rear - OK, that puts the turbo IN the radiator. Hey - cooling's overated, so lets ditch the radiator.
Finally you'll need to route air intakes and discharges to both of these turbos and back again to the throttle body - oh wait you'll probably want to mount a Skyline FMIC too - well, I guess now you can seeing as you don't have a radiator anymore.
People like you who obviously haven't investigated what they are talking about - and then come on here and start talking like a crackhead - irritate me.
Ah what the hell, do what you want - I've seen people likeyourself come and go before. Sure you may have some knowledge of turbo chargers but your common sense is missing. Typical book-smart syndrome.
Stubborn assclown..........
actually youll probably be pleased to know im going to be running an autronic from the great land downunder. You gotta be bringing sky lines into this.. Im gunna be able to kill them in the quarter anyway once im done
