vtr black top vs silver top

  1. #1
    what actually makes the power differencei gather its head work or something along those lines but what is different?
  2. #2
    black tops carb silver tops injection engine, ecu, and heads different i think there onli difference ect but dont not 100%
  3. #3
    cant be coz mines a black top and i can clearly see injectors so it has a ecu i.e injection
  4. #4
    they do a 90bhp black top, a 90bhp silver top and a 98 bhp silver top. All of which are injection

    ok then didnt know that lol so what changes did they make to get it to 98bhp as im curius

    location of catalytic converter (manifold cat instead of under car)
    revised inlet manifold
    3 plug ecu over a single plug
    slightly different head desigs ie: inlet port spacing, roller rockers over non roller rockers etc

    Carb? teh fuck?

    there was no "carb" engine version of the saxo. PSA phased out carbs in favour of fuel injection way back in 92'.

    lol db_sax you would have though that stupid cunt in your pic would have cut her hair with all that compensation. slaggggg sorry to go off subject ive got mk2 vtr in the weird year where its a mk2 shape but still got 90bhp engine, stupid french twats!!!!!! :@

    ive got a january 2000 vtr silvertop, how can i tell if its 90bhp or 98bhp?
  11. #11
    my mates got a got a black top swear he told me it was a carb engine, but i have neva worked on a black top, so onli reali no vts blocks, my bad.

    how many plugs come from ecu
    catalytic converter will be under car on 90BHP models
    what reg is your car? The 98BHP models were made 2001 onwards

    i havnt checkd the ecu pal, mines a v but the cat is in the engine bay like as soon as the mani comes out the car
  14. #14
    main gains were from the inlet mani, and the mapping of the newer ecu

    most likely be a 90BHP version on a V-registration. The 98BHP variant didn't come in til X-reg 2001 onwards.

    Black tops are roller rockers
    and silver tops arnt or one way or the other.

    the compression in the 98hp model is higher than the 90hp silvertop

    the black tops have dished pistons, silvertops have flat (i know the 98hp are flat atleast)

    the port spacings on the blacktops are the same as the 90, the 98 are different.

    its mainly due to high comp

    yours should be a 90bhp, but the mani is from a 98bhp.... so id guess someones changd your mani
  18. #18
    al check the ecu, is it posible that sum idiot has changd my mani and left the cat underneath in?? is that possible or not?? i need to check haha
  19. #19
    tis possible yes.
  20. #20
    oh no, i defo need to check that with all the bodge up garages these days. is it just the cat that gives it the 8bhp difference?
  21. #21
    forgot to ask, cud it possibly b an engine swap?? the lambda sensor lead is in the rite spot nd that
  22. #22
    only thing is is that if the mani had been changed and you had mk1 engine and loom you wouldnt have a second o2 sensor so would have a hole in mani somewhere cos apparently 98bhp models have 2 o2 sensors? some weird shit?!?!?!
  23. #23
    thats wot i was finking, the o2 sensor wud fuk up, like being in the rong spot
  24. #24
    holes are easily blocked up

    are you certain theres a cat under neath?

    they may of just whacked the manifold with cat on as that was the only thing avaibale at the time

    no.

    my early silver top vtr, the lambda sensor was not far from the head.

    now with my other mani on, its right back where it conects to the cat

    i havnt checked for a cat underneath, i just seen the short fat 1 in the engine bay nd presumed that was it, i will have to check like. wots if its a 3 plug?
