- Welcome to the MITchanic TH-cam channel!
This is my first video in a series that documents how I built up a 1983 Porsche 911SC track car to compete in the One Lap of America race. The following episodes will cover how I rebuilt and modified the engine to make 260 hp (44% more than stock), improved the suspension and brakes, and installed a half roll cage, race seats, and racing harnesses.
Episode 1 chronicles the teardown of the engine and getting it ready for machining. I recommend watching the engine rebuild series in tandem with reading How to Rebuild and Modify Porsche 911 Engines, by Wayne Dempsey. The videos largely follow the progression of topics in the book.

A technical professor who can rebuild a car. How rare
I try to practice what I preach. I tell my students that they should constantly build their mental library by studying other peoples' designs. Taking things apart, or in this case putting them back together, is a great way to learn from others' work.
The Mercedes Unimog is an interesting vehicle
Thank you for this video. I learned a lot and I am a new subscriber from Los Angeles, California. Yes Wayne Dempsey‘s books are helpful and I also know him and anytime I order parts. I normally go to will call and pick up my parts that I purchase sometimes he will come out, but he’s a very busy guy. Just wanted to say thank you for these videos that you have. I’m hoping you make more because I really learned a lot. Thank you.
Thanks for your note! There are a lot more coming. I have all the raw footage already filmed of the entire build. I have just needed more time to edit. I've been under a big push getting the car ready for this year's One Lap of America race. I should have the next video out in the next week or so.
I'm about to drop my engine. Thanks for taking the time to make such a detail video with explinations!
Glad you like it! I hope this series is helpful for you!
great video man
Appreciate it!
Best of luck. Having a 77 2.7 that needs a rebuild this is great!
Great to see this series Amos! :) Can't wait for the next one. 14:45 The fan design to ensure equal air flow on both sides is so clever!
Thanks buddy!
So glad i found your video, my 78sc has just developed a noise which has prompted me to look into a full rebuild.
Great work 👏 👍 👌
Sorry your SC is giving you troubles. I hope this series is helpful!
Hey Amos, looking forward to your channel from here in England, keep the vids coming 👍
The next one is posted! And I should have more come out more regularly now that it is the summer!

Awesome content! Can't wait to watch the next part. 👏👏👏
Coming soon!
Subbed in the first 21 seconds! I have high hopes this channel will be entertaining and educational, good luck!
What excellent detail in this video - Keep it up, please!!
Thanks! I just posted the newest video.
Hi there! Nice in depth video. I am a fellow G body owner (1984 3.2) and MIT employee (Haystack). I only Autox mine at Devens, but we may have crossed paths at Palmer for their casual events.
Awesome! Hope we run into each other sometime!
Real nice and in depth video! I’d love to see one on the unimog sitting in your garage!
Thanks! Maybe I will do one on the Unimog. I have to change the low-pressure fuel pump soon, so that could make for a good video. If you look on my instagram page, you will see how I had to intravenously feed it fuel to get it back in my shop after it died while plowing! Thanks for watching!

Excellent! I'm doing a 2.0L build.
Great! I hope this series is helpful to you!

nice video Amos
Thanks! I appreciate you watching!
Before removing the nuts or stud caps from head studs, it would have been informative to check if the nuts were tightened to proper torque. If they were not - eg then you know that is likely source of leak. I learned that from TH-cam channel: Klassik ATS (Kurt)
In hindsight, I completely agree. I thought they were broken, and when they were not I wasn't sure what was going on. But I figured out they were loose in the end.
@@themitchanic cheers! Looking forward to next episodes and track day videos!!
@@themitchanic Lately, all my garage time has been spent fixing previous owners' mistakes. The spark plug tubes, for example, had gone in dry, and the o-rings rotated and sheared. Thankfully, the water-cooled engines are cheap to work on.
Billie Joe Armstrong from Green Day rebuilds a 911SC!
Haha! I suspect he could afford someone else to do it!
I priced out 6 new cylinder barrels and piston kit for a 2.7, it’s about 4K. You mentioned you had your original cylinder barrels plated with Nikasil. How much did it cost to have them plated and is it possible to still use your original pistons, assuming that they are still usable? If possible can you expand in more detail on the process and where you had them plated and what can the savings be if going the plating route? Thanks
I had my cylinders done in 2019. It cost $1,387.32 to have the alusil stripped off and the nikasil coating applied then re-honed. This cost didn't include my machinist cleaning them up and shipping them out for refinish. He also had to re-machine the o-ring grooves at the top of the cylinders and refinish the mating surfaces that got chewed up. So his costs were about $500 additional. The original pistons in my 1983 911SC were only compatible with alusil cylinders. If I had used them with nikasil, they would have chewed up the cylinder. This is one reason why I got new pistons. The other is to run a higher compression ratio. I think stock a 911SC is about 8:1. My pistons are 9.8:1, which is about the limit with single spark plugs. Hope this helps!
Great video. Where did you get the cylinders plated?
Estimating tear down time from start to finish how many (ball park) hours would you estimate it took you?
Teardown is a lot faster than building up the engine. I think Wayne Dempsy estimates it takes 40 hours minimum to build the engine. But I would guess that it took me a total of near 40 hours just to tear it down, because I was filming and bagging/tagging everything. I highly recommend documentation because it is really easy to forget what goes where. Hope this helps.
