I'm doing a fairly large project on the interior of my 1971 914-6 GT clone this winter. I'm converting to 911 steering and ignition, adding a GT roll bar and harness mounts and a few other bits and bobs.
While it's open, should I cut an access panel? Is there any impact on the structural integrity of the firewall? How difficult is it to lean over the engine and adjust timing without the access panel? While it would be more convenient, I wonder if it's really needed to properly time the car every few years. It's a '71 2.2 liter "E" cam engine. Thanks for any advice. John Attached image(s) |

If you have a factory 914-6, I would not cut the firewall; did not cut mine either. I have modded my 6 but the body is still essentially stock with the exception of my louvered front trunk floor to vent the oil cooler. I think the biggest hassle is if you need to change your fan belt or alternator. It can be done in the car, but it's a task best left to young, thin mechanics with long arms. The best plan for these cars is to just drop the motor for maintenance. Valve adjustment, address any leaks, new fan belt, etc. Timing them is a slight pain, but manageable with the engine in the car.
I think structurally, if you cut an opening in the firewall, make a nice metal panel that seals tightly when installed - maybe riv-nuts. I do not believe it is going to weaken the firewall. (IMG:style_emoticons/default/beerchug.gif) |
