The order of things for reinstall

[Funracer]

Engine has been out of the car for cleaning and reseal, then down the slippery slope we went. So now I am doing a trans reseal. Then shortly it will all go back together and back in the car, I hope.

The big present I am giving myself and the car is a new SSI exhaust. The engine is still on the stand and not sure what to do next. Do I turn the engine upside down while it is still on the stand, then put SSIs on, then lower the motor and reattach the trans then put the whole assembly back in the car? Or lower the motor first, attach the trans, put the drivetrain back in the car, then put the SSIs on?

Seen many pics on the forum of newly resealed/rebuilt engines on the stand with exhaust and muffler already in place, so I know it can be done. Just looking for whichever way is easier for a first timer.

Thanks

If it's on the stand, you might as well put them on now. Saves some difficulty in stud extraction, if needed, as well as saves you from having to do it on your back or craning your neck.

Only downside, is that you'll very likely still need to do some oil line massaging once you're in the car, as I understand NOBODY sells an oil line that fits right out of the box. That's going to have to happen either way though.

Have fun!

Agree with Mike, it would be easier to install them while on the stand, especially if it's already there. It's not a difficult install, but everything is easier with more room.

I have a '81 911sc and installed SSI's. I'd strongly recommend purchasing new oil crossover lines that are meant for cars with SSI's (oil crossover line around the engine and the oil crossover to the thermostat). Your stock oil lines won't fit with the new SSI's in place. You might be able to bend and/or 'wedge' the original lines around the SSI's, but I would just get new ones, it'll fit better and look nicer.

Do a little bit of searching on it, it's a common upgrade, you could purchase them through PP or elsewhere. They'll run you ~$200. I had a local Porsche shop order them for me (I live in Alaska, so it saved me the charge of shipping).

(probably obvious, but also ensure the SSI's are compatible with your muffler! - I originally had a 1-in, 1-out muffler & cat, swapped to SSI's w/ 2-in, 1-out Dansk muffler, no cat)

I was hoping you guys would say that!

Thanks

How about axel shafts? Bolt them to the trans before I reinstall the drivetrain? Might be easier to torque the bolts properly this way.

Or attach them to the hubs then install the drivetrain? Or just do the whole thing after install?

Thanks

Do axle shafts after install. You can torque them from the side of the car with long extensions.

Ok thanks.

For the axle shafts, like most folks I don't have a torque wrench that is close to that big. I did the old, stand on a scale, push down on the end of a 3 foot long wrench and do the math to get approximate torque.

I then brought my socket and some cash to a truck stop with mechanics. I walked up to a mechanic and said will you torque two nuts for $20 bucks. It took him a minute and he made 20 bucks cash. My axle nuts were torqued to spec.

I think is is something crazy like 320 pound feet, but I would have to look that up to be sure.
