To boost the torque / HP, most effective MOD is... (archive)

..to ditch the AFM. You replace it with aftermarket engine management or a piggyback 'puter / Motronic combo or a MAF conversion. Something like this should be done first. Why? Because the results are greater than the cam timing benefits and it's cheaper and fairly straightforward by comparison. Some wiring and tuning, hopefully on a dyno is needed though if you want the best results.

NO BS. Ditching the AFM is the single largest improvement you can make to the S14 without rebuilds. Check the archives for some of my posts. Truely night and day noticeable, and you can tune it to new mods or that future 2.5 conversion.

The vanos stuff won't go onto an S14. If variable timing was done, an actuator between the cam gears ALA Porsche would work well. Lots of fabrication and some engine management changes and increased control (of the cam gears by the ECU) would be needed. It's kinda tempting though, since the cams have those little round access ports on the front of the head... Oh yeah..there used to be a guy (Franco)who made self adjusting cam gears for belt drive VWs using a spring and weight approach like an old distributor.
