Best bulkhead mount options? Options

[SKL1]

Finally getting ready to send my '71 I've had since new to the restoration boys at Stalltek for paint and six conversion work.
I've never figured out the search function so would like opinions on the best bulkhead engine mount options- want a factory look and will be doing a mild 2.4 E engine build. The car has already been converted to a side shifter some 30 years ago... getting the sheet metal I got here on a group buy powdercoated as we speak.

Have at it guys...

Just for some tight numbers onthe Naro mount; if you locate it where they indicate the motor is 0.85" low - this can be rectified by welding the mount upward by 0.85".

The other issue is that the Naro mount puts the engine 0.5" closer to the firewall so you would need to space off the mounts 0.5" from the firewall.

The Patrick mount has offsets too that I have measured that are similar, but not exactly the same - If someone wants those I could dig them up (it's all in CAD).

Yes, I had the space from firewall issue as well. Had to weld up some stock to make it work.

And . . . We are right back to the discussion in the other recent thread about having to modify aftermarket parts to fit and do the intended job (IMG:style_emoticons/default/lol-2.gif)

Yea, there’s that. In this case, it’s not a replica of an original part. It’s supposed to be something better or at least a quality alternative. I didn’t find that to be the case. YRMV.


One thing I would be curious is how much torque is on the engine mounts and how strong do they have to be? I haven’t heard of any bulkhead mounts failing under any circumstances. Not to say I have superior knowledge or experience with the mounts. I’m just wondering how much strength is needed and does a big engine need a different mount from a small engine.
I think I remember someone noting that both factory 914-8’s use a stock style mount. If that’s true, that gives us an idea what Porsche thought about the issue.
