Not sure on engine differences, actually the only difference I know of other than 100cc, is the 2.6 come with xenons as standard.

All the GSi's had MSD stuff, they were all SRi's that went to MSD and got 3ltr cams, lowered suspension, bodykit, recaros, and some other goodies, think the 2.5s where supposed to be 192bhp not sure about the 2.6s but I've seen a 2.5 with a panel filter and cat back exhaust that got 208bhp

found it:

SRi 2.5 V6 = X25XE = 167BHP
SRi 2.6 V6 = Z26XE = 178BHP
GSi 2.5 V6 = X25XE = 192BHP
SRi 2.6 V6 = Z26XE = 178BHP

The first digit from the code relates to emission legislation.current petrol cars need to meet Euro 4

Z= Euro 4
y= Euro 3
X= Euro 2
C= Euro 1

i guess they made the new 2.6 engine more eco friendly, so total vaux may be right about the performance stats.

2.6 GSi has less power but more torque than a 2.5.

202 lb/ft of torque, not bhp.
