My SC is a modified repaint and will never go up in value from my purchase a few years ago. Dropping another $15K worth of engine just makes it worse IMO.
BUT, dropping an LS in and a iroc or RSR body on it will return driving smiles for the next 20 years, haters be damned. 
My biggest concern is what/how to replace the 915, for which I have ZERO love. I saw the Subaru trans swap, and have heard about a g96 swap being reasonable. The 930 is a tank, but is typical Porsche expensive...
Any pointers, other than "sell it and buy a Vette" |
I agree, spending minimum $15,000 on a rebuild makes zero sense. I’ve got a 76 912, and makes absolutely zero sense spending $30,000 to buy a core Porsche flat-6 and trans, and build them to stick into a $30,000 car.
Advise Is really, really figure out what kind of engine character you like: do you prefer a lighter higher revving smaller engine, or a very torquey LS? Really do try to drive a Vette and see if you like the feel of the LS.
If you find you prefer a lighter engine, a Subaru -6 turbo or VW VR6 are great choices. I’m personally going with a built normally aspirated Subaru 2.5 at around 215 hp and 275 lbs weight.
If you prefer an LS, that’s a great choice also.
Note that an LS will require more cooling capacity and bigger breaks than a lighter Subaru.
The Subaru 5-speed is a decent trans, orders magnitude better than the 915, holds up fine behind an LS.
