3.6 Too Big??

I am considering installation of a 3.6 into an '80 SC. I seem to recall hearing something about later 3.6's being too tall to fit into SC engine compartments. Does anyone have any information on this? Will all 3.6's fit or only some (and which ones) ? Thanks in advance for any responses.

Don

There are many on this board that have done this conversion. Do a search on "3.6 and conversion" or something along those lines and you'll get a plethora of information. There's a lot to learn

They will all fit as long as they are air cooled, you probably can put a water pumper in but tons more work, Get your check book out, this is not a cheap conversion, Kevin 82 3.6

My '93 3.6 fit fine in my 78SC. Moses put a Varioram 3.6 ('97?) in his SC. I have never heard of a problem with a 3.6 fitting into any 911. The most difficult thing is working out the exhaust, until you give in and go B&B, which isn't a bad thing. I agree with Kevin, plan on a big checkbook.

I can't close the engine lid, but who cares!

Actually the opposite. I was concerned with the motor hitting the ground on speed bumps so I raised it a bit. Minimal clearance under lid.

I think the only thing that does not fit is the blower unit. I also think I remeber reading that a 3.2 unit does fit but I am not 100% sure on that.

Bill Verburg managed to fit the stock air cleaner and the stock heater blower in his Carrera 3.0 engine compartment, without a wing. I'd always heard this was impossible, but he spent years driving around in proof to the contrary.

And if I had a motor as pretty as Moses', I wouldn't want to close the decklid, either.

The top of the f/i stack is a very tight fit to the bottom of the parcel shelf. They all do need ~1" spacers and longer bolts at the rear motor mounts as well as reshaped/reinforced rear cross member.
964 w/ stock air cleaner and stock heater fan in my '76 C3


993RS w/ stock air cleaner and Thoms c/f heat tube in the same chassis.

Bill,

How are the welds holding up on the engine mount bar? When I swapped out the 2.0 for the 3.0 in my car I found that the mount bar had been repaired so I installed a newer mount bar. I wonder if the bigger motor and the spacer will put more stress on that spot...

Chuck

The 964 one was fine after quite a few years of use ,but was modified and reinforced for the 993 anyway. I assume it's still ok, but that's one of the things i plan on checking on over the winter layup.

I have heard of quite a few of these braking even on stock applications. They are not meant to withstand much fore/aft or twisting strain. W/O mods a 964/993 provides such forces on them.
