Back in about May of this year I was sitting around having a bite to eat with Teby, Anand, and Pat Downs. Of course we were talking about Speedsters, motors, and other car related topics. Pat chimes in about when I'm going to get a bigger engine so I can beat Teby in a race. I reply I'm a few years away from getting anything bigger because these motors aren't cheap. He says he can get me a screaming deal on a slightly used long block and wants to know if I'm willing to source some a few new parts so I can get a 2110 cc motor. I tell him to get me the details and the project was started.

After getting the used motor The Madness set in rather quickly. The idea of using the slightly used case was replaced by sourcing a brand new AS-41 engine case, full flowed, clearance for stroke, 90.5mm bore, bronze lifter bores, cut for sand seal, and shuffle pinned. Then a brand new custom OT pulley was sourced and further customized with a steel hub. As the project progressed I sourced an original 356 oil canister for the purpose of having it made into an oil breather. I was also given an exhaust for a 356 B/C car that was modified to fit my Speedster. There was just a little bit of bumper bracket clearance issues that were taken care of on the day of installation. Some of the tins were powder-coated silver and other parts were powder coated black in order to replicate a Super 90 motor. Reproduction stickers were also obtained and expertly applied by Teby. After just 6 moths the motor project was completed then it was a matter of removing my old 1915 cc motor and cleaning up the engine bay. I'd like to thank everyone involved especially Pat, Teby, and Anad for their dedication to the hobby and their exceptional skill and Speedster knowledge.

Here are the results of this summer project:

It was a labor of love for everyone involved and I'm super pleased with the results. Once the break-in period is over I'll get a chance to see what it really does but so far it's an amazing motor with quick throttle response and some serious pull.

Wow. Love it. 

Could you provide the details on the oil canister  / breather box?

I searched the internet, mostly The Samba, and found an original Porsche 356 Fram oil canister, clamp, coil bracket, and mounting hardware. The guys were removed and a cross piece was welded at the top of the canister and tapped to receive the bolt. I paid about $225 for all of the pieces. I had it blasted and powder coated.

I forgot to mention that for the engine bay I used some industrial degreaser and scrub it down pretty good, rinsed it off, and let it dry over night. Prior to putting the car away I did use some heat resistant paint and painted the engine lid brackets grey. The next day I taped off and blocked off whatever I didn't want to get sprayed black and I used Hercules brand bed liner paint and sprayed the engine bay and trim pieces.

Looks good. I like the wheels and caps more than I thought I would. Nice work.

Why did it take 4 of you to install that motor? 😋

If you look closely two of us are working. The other two are providing comedic relief. LOL

Actually, Anand is the technical details expert and Teby is the historian preserving the work for future generations. Pat of course put all of the sourced parts together in a way only he can.

@RobertM : Did you guys do a rain dance when you did the motor installation?  I feel like I haven’t seen a dry road since you posted the pics of your install!

 

It must be raining because of it. Every time I say, "Let's drive on ________", it's rains. I need to NOT plan to drive so it'll stop. It's been a week and I still only have 10 miles on the new motor.

I, for one, appreciate what you did for us @Robert M. I was growing quite tired of choking on all the smoke from the Camp Fire. Driving the speedster wasn’t exactly fun while wearing a N95 mask. 

Also, not having any measurable precipitation since April, the Northern California community thanks you as well. 

You’re a good man who put aside your fun to bring water to the state.  We should have a badge made up for your grill
