Is it a faux pas to increase displacement on a numbers matching engine? Does this detract from, or increase value? Just curious. I wouldn't want to do anything irreversible to a numbers matching car. Any thoughts?

the biggest faux pas to engines is when you enlarge the spigots to make a 2.7 for example. 911S cars are hurt the most with unoriginal parts. Chris

Virtually nothing done to an engine case for increased performance cannot be unwound. Including enlarged spigots.
We're sleeving a blank 67 case right now with that very condition.
This has become somewhat of a new phenomena where we allow a future owner who we probably don't even know determine for us what we do or don't do to enjoy our cars. I always advise my customers to build what THEY want. We can always return it back to stock later on.
The beauty of the 911 engine platform is that it's fairly easy to find 20-40 hp with parts and machine work.
just chev it

Thanks Frank. I like your comments.
I stored my original matching numbers 2.0S engine and had a 2.8l twin plug engine built on an early alu case. It rocks in a SWB!
Keep up the speed!

I had to make the same decision and decided to stay in a complete re-build, with all 2.0L parts and specs on a matching numbers car. If I want more performance, I drive the 997. The 1968, is what it is and what it was made to be.

Most vintage long hoods can be beaten by today's Honda Civics. I, for one, think adding HP is core to what makes an enthusiast. I do not understand anyone who would complain about an additional 30-40 HP...
