What is the best and safest way to up the rev limit of 4efe

[andyllewellyn]

As title, have a decent sr and want some more power, the revs pretty much drop off at 5800, can i fit the glanza cam springs and get it revving to 7800 or more, it is pretty much the same engine so in theory should be possible, other option is drive this engine into the ground and replace with a 4age, 1.8 vvti(140-190-g6-6speed) or supercharging but might be a hand full without power steering.

Has anyone tried charging these, the power steering can't be that much of an issue can it?, i have seen polo's with 200hp plus(mk3g40) without power steering, even my old golf gti mk2 had no ps, so to charge or rev, pls help

Change valve springs to something stiffer like the zisco ones and fit ARP rod bolts. One thing I always found with the N/A was it was lacking revs.
