haha yeah, it was a bit more comfortable. This morning I woke up to -7 degree weather, maybe 15 degrees in the garage made the dining room a clear winner.

Thank you. it’s a black powder coat wit some wrinkle texture added. I wanted something a bit different but not to loud.

Here's a pic I just dug up from a thread from 2021 when I did it. I did black mini-texture powder coat on mine...
Great minds think alike!! 100% twins other than your sweet Varioram script. I think I may have done a medium wrinkle, and pictures of your engine bay?

Sure... here's my engine bay. 😂





But here's another dining room table shot of some of what will be in there. The cone filter may or may not be. Was just toying around with it.

Impeller housing is satin black powder. Gold paint + 2K clear on the impeller. Filled the timing tick mark with some red. Also gave the ISV and the tubing to it a quick polish... nothing crazy but they were tired looking.

@boomboomthump Goodness, that is some sexy sh*t. Definitely bookmarked for future reference, the golden impeller blades would look mighty fine on my ocean blue metallic.

In Saxon's case a single sheave pully is need to fit the space allotted by the 3.2 engine mount console he is using
Saxon's w/ 3.2 engine mount console and 911 crossbar and Clewett pulley

Mine in a similar install in my '76 C3, w/ RS single sheave pully and 993 RS engine mount console and 993 cross bar

Man, that came out Great! I like the little details, red line, polished pipe and V-ram logo, looks great! That gold has me questioning my black fan, LOL! I ran a cone filter for the last 7 years on my stockfish 3.6, it was completely fine, it will probably look cleaner than my new air box setup. can't wait to see that come together.

Just a bit of progress this week, dropped the car off for additional body harness cleanup and got the intake manifold mounted.
Also, I got to drool over a real RSR and a SCRS at the shop

Small Update, the wiring harness on both the engine and body have been rebuilt.
I have no before pics, but the old harness was a hack job, chaotically finished in green electrical tape. This setup is so much cleaner with a main harness quick release.

Work has been hectic, but I was able to get a free day to start the install. Got a bunch of odds & ends finished up, and the engine is now mounted. I need a few more hours before we are ready to fire but we are getting close

@Bill Verburg
there is a 1/4-3/8 inch gap between the Sheridan surround and the rubber skirt right now, I think I may be able to close that gap. If not I will either order a longer skirt or rivet a rubber extension to the skirt.

Looking good!

Question, seems like you had some work done to stock 993 heads to fit the larger RS valves and you mentioned they were ported a bit too. Were the intake ports opened up to the larger RS diameter or did you keep them stock diameter? On the Varioram, the intake manifolds which lead down to the heads are also slightly larger on the RS to match the larger intake ports, so just curious if you went this route or not.


I'm planning an RS-spec 3.8L build. Thinking about getting RS heads ($$$$) and just selling my stock ones to offset costs.

How much - average - would a 3.8 rebuild run at a competent Porsche specialist these days?

Depending on what you're doing, I would say the range is $10k-50k. So "average" is somewhere in the middle there. I'd say most people are somewhere in the $20k-30k range if you're having a shop do the work (again, range varies on what you're doing).

BTW, that $10k is based on piston/cylinder set, DME reprogramming and just labor to drop the motor and swap the pistons/cylinders. Onwards and upwards from there with cams, valves, head work, etc.

In my case, I'm thinking of doing a full RS-spec motor. All labor myself with exception of machining the cases. Cost is right around $20k for parts + case machining + flashing my DME. No other labor.
