ok.. this might take some time..
Induction kits..
most of them are generically the same, jabbasport.. bbm.. whoever. big cone filter on a stainless L-bend with a heat shield. They make an awesome noise and you have the choice to retain your boost return.
the twin swg kits are very swish, and look stunning, but whether the gains reflect the cost is questionable. now these only work if you've deleted your boost return, which a lot of people do anyway as it stops the warm oily air going back into your charger. the 'charger actually uses this warm oily air to lubricate itself (oo-er missus).. so if you lose the boost return you have to spray the inside of the charger with a ptfe grease at regular intervals to keep the apex seals nice and supple.
i personally use a jabbasport type induction with the heat shield, and have retained my boost return, mainly because i use a 65mm pulley and want to keep it all lubricated as vw intended.
Exhausts! supersprint are fine.. i personally have a milltek system (not sure if you can get these any more) and i love the tailpipe design... the noise.. the fit.. well yeah, i like it a lot
as with everything milltek though, they are a bit costly. darren at
www.g-werks.com can sort you out a full system, and manifold for a rallye.. and i'm hearing good things about these.
Heads! the G60 head in standard form is no better flowing than a standard 8v GTI head, so its one of the mods that a lot of people put the most thought into. the choice of head can determine how the rest of your engine can be built up. now i may be wrong about this but i thought the crossflow head came from a new shape beetle, only available in the states, im not even sure if these are a direct fit so i cant answer your gasket question im afraid. (rubjonny may know!)
there are tons of good options though.. a simple port/polish.. or maybe tri-angle valves, or even a big valve head. there is the 16v head option, but with the work and parts required to do that conversion... you could do a 20v turbo swap (not that i would ever condone that in a rallye
)
Superchargers! now i dont know the current spec of your car so i'll assume you have 4 options. ill list them in order of guesstimated cost and power gain.
1) port/flow your current 'charger, use a smaller pulley (spins faster, more boost) and you could also use a toothed belt system to avoid belt slippage at high revs.
2) m62 eaton charger from a merc. good efficiency, reliable, no service worries like with the g-lader (this actually applies to options 3 & 4 too) im not sure if you can get an 'off-the-shelf' kit for this, but the boys at
www.pitstopdevelopments.com can help you with that.
3) rotrex supercharger. as above but i think a little more efficient.. and higher cfm. think it would work out costing similarly to the eaton. storm developments have been working up a kit for this.
4) the daddy... the bahn brenner twinscrew lysholm! this thing sounds as sexy as it's name suggests. it can be mistaken for a police siren when backing off the revs.. i personally love it but you can buy a silencer kit for it (for the wimps)... yes thats right
KIT . bahn brenner produce lots of lovely goodies for the G60 in kit form. the lysholm kit allegedly can be fitted by a compentent DIY'er in under 4 hours. you can get smaller pullies for these that can push out some silly psi. only downside? bahn brenner is based in america.. although they do have a couple of official UK importers.. maddogsyndicate, and yep.. g-werks of course
im rather tired now..
