the 2.5's have ignition leads and a coil pack and the 2.6's have 2 rigid coil packs direct to plugs, thats an important diff when thinking bout maintenance!!

202 lb/ft of torque, not bhp.

my mate had the Pre face lift Veccy GSi and it was the 2.5 with MSD on the engine cover and slam pannel

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.

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

Taken From Total Vauxhall :boggle:

A 2.5 gsi is around 192bhp standard, the 2.6 was about 202bhp.The 2.5 v6 sri (like mine) is 167bhp.

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
