   90bhp engine has a single plug ECU and the Cat is located under the car whereas the8bhp engine has a 3 plug ECU and has the manifold on the manifold.

   im guessing it comes from the ecu factory mapped to run slightly better?

   I very much doubt the extra 8bhp will be noticeable in the real world. I could be wrong, but I think the power comes from a cam change and revised inlet/ exhaust manifolds.

   theres a sticky with all the information, easiest way is too look at the ecu and the oil dipstick location.

   no, it was to comply with emmision regulations, hence why you pay cheaper tax on the 98bhp models, and on paper you get more mpg.

   makes a difference in the real world, people used to argue that on here, driving both cars a 90bhp and a 98bhp, the 98bhp is quicker, and along side, the 98bhp always pulled away.

   early mk2's which still had the single plug ecus dont have plastic throttle bodies.
   
   all VTR's registered after march 2001 were 3plugs.

    The 8bhp more makes bearly no difference, it will accelerate a little faster and probably will beat a Mk1 but its nothing liek the differences between a VTR and a VTS.

    The 8bhp possibly comes from the less restrictive exhaust on the 98bhp models. Its probably not the only change but a 90bhp standard exhaust bore is tiny. You'd probably gain a few bhp on a 90bhp model just by sticking a standard 98bhp exhaust on it.

    I wrote my 98bhp mk2 last week, picked up and drove home a 90bhp mk1 today.
    
    I was worried after finding out i'd lost 8bhp i'd feel a but sluggish so I was looking for it all the way home, honestly I found the mk1 zippyer and more nimble-feeling.
    
    My old mk2 was on 57k and this mk1 is on 22k though, so maybe the less miles and just coming out of a service gives it more than 8bhp over the mk2 with miles + 6-7 months after a service.
    
    So yeah, dont worry to much about the bhp difference.

    I Wondered the same thing, got the full service history though with all the miles going up slowly, plus when I picked it up it still had the original 4 factory tyres on it :>

    It is not even an 8% difference in power between the models so I wouldn't expect much of a difference. It is not a magical 8bhp.
    
    I think Saxos themselves can vary. I test drove an '01 VTS and it felt awful compared to my VTR.

    Probably could of picked something up cheaper from a private seller, but I know next to nothing about cars and depend on it working for my job so I went the dealer route.
    
    Going to tinker around with it a lot and maybe next time I buy one i'll know what i'm doing

    Paper figure's show much improved performance..
    
    Higher top end, better fuel economy, less emissions and better acceleration..The extra power comes from the revised inlet..

    98bhp gain a lot more torque with breathing mods than 90bhp this has been proved many times as well.

    The official change over was 2001, where all cars registered after Mar 2001 were 98bhp.
    
    A small amount of cars before that date had the 98bhp engines in, eg. very late 2000 - 2001 cars.
    TBH i have only ever seen 1 or 2.
