well i had pretty much the same motor in my car without the twin TB and it went better on 98 octane but on 91 octane its not alot better than stock, probably 5-10kw more at the most.

but thats only seat of the pants, i haven't dynoed it.

^^ Thats pretty much what I was thinking with 160 tops.

Factoy ecotec - 147kw
and another 10-15kw tops from a good set of pipes and a bit more timing up top on 98.

I wouldn't expect any significant gains from the twin throttle body alone, not on essentially a stock motor.
