The standard 2.5 V6 in the Vectra SRi and CDX has 170bhp. The 2.5 V6 engine in the GSi was modified by MSD to give 195bhp. MSD made changes to the engine management system on the GSi and gave it different cams, that's why it's more powerful.

Well I think the 2.6 V6 GSi is a OK car, but as for keeping up with Scoobys, who are you joking. If you give an opinion, make it a right one. Maybe non-turbo Subaru Sports, but if you put any of the Vectra models up against a proper Scooby i.e a STi3, a Vectra wouldn't stand a chance. 0-60 GSi 7.7, 0-60 Scooby under 5; come on lads, get your facts right.

I completely agree, having owned a 1998 standard Impreza Turbo estate, and now having a 2.6 manual Vectra, it's clear the Subaru would completely toast it. The Vectra is not much better on fuel, but there is something good about it.

Hi, I have a 2.6 V6 and I'm finding it hard to find spare parts, but it is good to find someone who likes the same car. Mine is now 15 years old and has a genuine mileage of 74200km from new. I am looking for a computer screen; if you know where I can get a cheap one, you can reach me on voycars@hotmail.com.

I agree, I have a 2.6 SRi 180, and it's a stonker, even as standard. However I have since modded it; Courtney lightened flywheel, Viper induction, increased fuel pressure, Powerflow dual exit exhaust, reckon it might be about 220bhp now, and it eats Scooby's and M3's for dinner.
Had some problems though. It drinks a fair bit of oil. Vauxhall say that up to a litre every thousand is normal, anyone know for definite? Front drop link bushes had to be replaced at 20 thousand, new intercooler, and that's it so far... going soon to be replaced by a Zafira GSi Turbo.
