Is the Turbo Viper kit different to the NA in any way at all? Also what kind of performance increase are we talking on an NA? cheers

They are completely different kits for each car. The VXT kit is currently withdrawn from sale until the AMM issue can be looked at. The N/A kit is still available however. I'm not aware of anyone who's done a before vs after rolling road on one yet, but everyone running one has noticed a good improvement. I had one on my N/A and it certainly went a lot better. Interestingly, I've just had a graph emailed to me by a customer running a Vectra 2.2 standard other than the Viper. This was rolling roaded at 161bhp! Certainly a power gain of 5-10bhp should be expected.

Only VXT's have an AMM so NA Vipers shouldn't have any problems.

Would anyone mind telling me if the part number VFC244 is the correct Viper for the NA?

[B4D_VX]

Yup, that's the correct part number. That should correspond with the fitting instructions in the box.

[davehutchinson]

The fitting instructions say 2 litre! Which is why I was confused Thanks a lot for getting it so quickly for me B4D, it's much appreciated.

[B4D_VX]

Yeah.......occasionally their fitting instructions have things like that in it! It's the right kit you've got though. As for the amazingly quick delivery, no worries at all Pete

Streetboy helped fit this today, thrilled to bits with the noise Really gives it the sound it deserves! The car does seem to pick up quicker too from lower revs, throttle response is much improved.

sounds better with the roof off! Went out today for the first time with viper and no roof, you don't have to boot it past 3k revs to hear it. bwaarrrrrrrrrrpppppp!

I keep opening the passenger window The sound really is quite intoxicating!
