I have seen a few tribute GT cars that are great, but you all know me. I really love doing the obscure.

I have access to some aircraft cases and was thinking about taking 2 IO540s and adding another bank of pistons to one. Yes machining the cases, welding it all up and same with the crank. Wouldn't be cheap, or easy. But if I could make the motor, I could do the rest.

Anyone know what the displacement was ?

Or any other specs

3 liters... 300bhp

Although I believe there was also a 2.1 liter turbocharged version that had approx 4-500 bhp

But I could be wrong.

It was the 908 race engine and 908 trans. Since the 908 was already mid engined, it fit really well - once Porsche moved the trunk firewall. Using an aircraft engine will be more work than Porsche had to do since you have to fit everything around the engine, adapt a trans, clutch, headers, etc. and then you don’t really see anything in a 914 engine bay.

I do want to do a silver 914-8 tribute but just exterior and interior. I’ll be happy with a six in the engine bay.

No, but it has been done with VW engines. In fact IIRC young Emerson Fittipaldi did this when he was still an up and comer racer in Brazil.

Why I say no is because aircraft and automotive engines are very different. Aircraft engines spin at slow speeds, 3000rpm redline, where they make the HP is with very long strokes and big pistons, 0-540 is 130.2 piston X 111.1mm stroke.

Automotive engines use much smaller bore and stroke, and a higher 6000 and up RPM, in the case of the 908, 85mm bore X 66mm stroke with a peak power of 370hp at 8400rpm.
It would be easier to weld two VW T1 engines together and then use SCAT split port heads.

But then the engine is too freaking long...and for the coin you spend on custom machining you could likely have a real nice /6 conversion.

The IO-540 was designed with a redline of 2700 RPM. Not only are you talking about welding in a case and crankshaft, but also completely redesigning the engine from the inside out.

So, yeah, you're off your rocker. (IMG:style_emoticons/default/wink.gif)

You're *far* better off trying to find an actual 908 engine...

Edit: correction, I was a bit off, this was two engines coupled together.

It's interesting though, I never noticed that they had moved the firewall back on the 914-8 until just now. The picture always seemed a bit off but I couldn't put my finger on what was different. (IMG:style_emoticons/default/wacko.gif)

The cheapest way to do this would be to use a Tatra V8 air cooled engine.

Do we have to crank start it every time? Seems about right (IMG:style_emoticons/default/lol-2.gif)

Two 2.2 hot rodded VW Beetle engines in a 1100 lb Beetle chassis. 400+ HP and it had a swing axle suspension and DRUM BRAKES!!!!!

And you think I am crazy for building my 4.0L 914. This makes me look like a piker.......

Just do a really well done V8 conversion. No one will question your sanity except those of us who know you personally. (IMG:style_emoticons/default/blink.gif) as far as the other is concerned, you practically have an in-house machine shop now so... (IMG:style_emoticons/default/drooley.gif)

No they are electric start, but it's a 1930's Czech design, back when the batteries weren't so reliable. There's another YT vid with a guy starting the engine with a tie down strap.

I agree, a LS alunimum engine would be my choice, I've been thinking about doing this to a 996.
