I'm thinking of doing a 917 with a 993 engine ... is it possible to make 500-600hp, n/a, out of a 993 engine? Alternatively, if that was the power goal, is there a more appropriate n/a, air-cooled engine one could use without breaking the bank (e.g., later year gt2/3/etc.. ... I'm very unfamiliar with porsche engines so I ahve no idea what is air cooled and what isn't)

 

500-600hp in a N/A air cooled (or water cooled, for that matter) 911 motor is a pipe dream. Porsche has done it in a street car exactly once, in the 2012 GT3 RS 4.0 - and I doubt you have the engineering capabilities on hand the factory does. Since you aren't putting a flat-12 in your replica, and exact duplication is obviously not that important, why not use a GM LSx series motor?

 

For a project like this; the only logical thing to do is Mig weld the fly wheel to the alternator pully of motor #2. EASY 750 HP. and solves the 12 slug issue.

 

I would have to agree with Chase, just slap on a GM small block and call it a day. With all due respect, it's not prudent to waste a 993 engine on a kit car. I'm sorry, but I tell it like it is.

 

I heard welding to the crank-pulley of motor #2 creates vibrations, definitely alternator pulley...

 

Stack two 993 engines on top of each other and connect the flywheels with a serpentine belt. Problem solved.

Also, the 993 is water-cooled. Air-cooling didn't start until the 996 model in 1999.

 

Might want to edit this post.

 

Shhhhhhhhhh...let me have some fun

 

huhh???

boy, you just can't believe everything you read on the internet now can you.

 

wow guys, read some of NP's previous posts.

 

Buy Gabe's engine and you will be there :-)
Very well built engine

Why not a 993 Turbo engine? You can get to 500 HP there. 600 is a little harder.

 

A 917 kit car with that turbo motor would be great. Even a n/a motor would be fun. What's your target weight, 2000 lbs?

 

LOL
this must be a troll joke.
Building a 917...

your best option is a small block chevy.

Maybe one of these perhaps...
