I know that the hydraulic is frowned on. All of the later type 4 motors went this route. Even the last Type 1 Beetles from Mexico went there too! The newest 911 are hydraulic.
I am not going racing just crusing in my 73 2.0. I know the power band is different but most of the driving will be under 4500 rpm. I plan on running some modified Hoffman AMC 2.0 heads, 94mm Euro pistons, 1.7 rockers with 911 swivel feet, solid rocker spacers and stock FI. Nothing exotic. |

I also refuse to use hydraulics.
Anyone too lazy to adhjust the valves in their engine should go buy a new Honda! Do searches here, on the STE, Pelican and my forums to find out whyn they are so horrible. My 4th Dimension Radio show this week will be on this topic, be sure to listen in! I just went 100K miles without needing a valve adjustment with my 912E. The last time the valves were adjusted was 4 years ago this week! The key is good solid parts, quality assembly and in my case cryogenic processes played a key role. I have a thread about this on my forums now with plenty of info. Build it right and keep it cool and you can easily go 10K without an adjustement. I will say that I have checked my valves every time I have changed the oil, but not a single one has needed an adjustment made! Hydraulic lifters also need adjustments, contrary to popular belief! |
