Να και καποιο σχετικο,σχολιο με τις 2 γενιες κινητηρων silvertop:it all depends on the year of the silvertop, 91/92 not so good, 93 94 sweet, my car at the moment holds a blacktop no problem with small mods, if your after stock power the black top is the way to go, if you want to get the power rolling a silvertop is better with the slightly heavyer internals, also the silvertop has a closed combustion chamber over the blacktop
the blacktop has a slightly bigger intake cam, silvertop is blanced but blacktop things go even ligher

as for the 91-92 silvertop they are very very badly matched on the inlet onto thehead its let them down badly they have a box like cut out, the later silvertop an blacktop have a teardrop this layout flows alot better and also matches the head better, easly proved in my car, any early moded silvertop I can pull atleast 2car legnths on them by the end of 2nd gear

and the torque toyota has rated the engines the same :/ blacktop has a slightly higher redline, in any race my car's best shift point is at 8000rpm with small mods.

with your BZG since its a 1999 model it is very possable you have an advantage over 95/96 blacktops just like the silvertops, the 6speed is good for track racing holding your revs high, but in a 1/4 its not so flash, also its ratioed to max out at 206km while the 5speed 239km
