ur father wants to play2 turbo?
if not, better get the normal v6. but beware of the gb.
if evo or twinturbo manual, the gb will not give any problem.

the first one (with grey rocker cover) the engine looks senget.
the 2nd one is ok.

performance wise:
very powerful 270ps engine, 2wd makes it more powerful (less power loss as 4wd).
u will feel the g-force pull compared to ur H22A.
people not familiar with fwd turbo must beware as there will be a lot of torque steer.
can get 250kmh no problem.

FC:
can be better than normal auto v6 or maybe auto h22a as it is manual.
but the FC can be high if always boosting.
hiway can save FC as u are cruising, in the vacuum range not boost.

but:
evo manual gb is close ratio.
cruising at 110kmh is around 3.5K rpm. bunyi bising.
sometimes, ppl tend to change the clutch plate to performance one like heavy duty or semi racing or racing clutch. so clutch keras.

if ur father likes smooth engine and always travelling, better get twinturbo.
if dont mind the bising, get evo.
evo more powerful than twinturbo.
twinturbo can maintain top speed much longer.
FC about the same...
