   was just wondering if a blacktop inlet manifold would fit on the silvertop engine cos apparently this is where the extra 8hp is gained from through the inletmanifold. and would it take alot to convert it? cheers peeps

   The inlet ports on the silvertop head are in a different configuration to those on the blacktop head so not it won't fit.

   Well an S1 Rallye inlet will only fit the black top heads and not the silvertop either becouse of port spacing or the studs. So no a black top inlet manifold wont fit a silvertop.

   Is the throttle body the bottleneck then?

   will have to be made from atleast 10mm alloy, a machine shop will have to do it....
   
   will give it a bit more life yea...
   
   would be better to spend the money on a cam though for more power.

    Why are you thinking that blacktops have an extra 8bhp?
    
    Its 2001+ (3plug ecu) vtr that has 98bhp instead of 90.

    i was always led to believe that blacktop was the newer 98bhp engines and the only real difference power difference was in the inlet manifolds? correct me if im wrong

    Nope, silvertop (with a 3 plug ECU, 2001 on, as said) are the 98bhp versions, blacktops, and silvertops (with single plug ECU, pre 2001) are 90bhp. The difference isn't the inlet.
    
    I'm not entirely sure what the difference is, but there's definately not enough of a difference in the inlet for it to make an extra 8bhp.

    right to clear things up
    blacktop-90bhp, single plug
    early silver top-90bhp single plug
    late silver top-98bhp three plug
    
    and you will NOT gain 8bhp from changing the inlet manifold, the extra 8 bhp comes from a lot of different modifications, if you have a black top engine or early silver top engine and you wanna change the inlet manifold fit the 106 s1 rallye inlet, but it wont gain you much, just makes a nice sound, really needs to be coupled with the rallye head, a ph2 cam and a remap and then you could be looking at around 120 bhp but it wont fit the 98bhp later silver top
