I just bought this hurricane damaged Prova countach, and will be rebuilding it on Youtube.   I can't believe I finally have my dream car in the garage.   I know you should never meet your heroes, but It should be a lot of fun.
Here is the Youtube link

Good to see you working on that beauty still Mike! Following along with your motor swap!

This is awesome!

Glad to see you're still at it. The 3900 is a great engine! Probably the best modern swap out there for anything Fiero

Thanks buddy! I'm glad to see you're still around here!
I've been doing a lot of researching, studying, and even taking some online classes about sound dynamics. For many many years people have been trying to get their builds to sound like a Lamborghini, even with engine swaps, 180 degree headers and so on. I have heard many people on these forums say its impossible because of "dual plane VS. flat plane" engines, lower reciprocating mass, shorter stroke, valve size and so on.
I have said all along it has very little to do with the engine, and everything to do with manipulating and multiplying the sound pulses, eliminating some and amplifying others.
I have chose this engine because I believe it will be the easiest to accomplish a high "F1" exhaust note from. Although the sound can be replicated by any engine (4 cylinder minimum), this engine will do it easily/cheaply and also yield more H.P. than most other 6 cylinder swap options.
You're gonna have to come out and do another video when its done lol!

I'm guessing a good chance of an aftermarket, or at least different ECU since it's a 3.8 SC motor.

Did you ever consider installing electric power assist instead of hydraulic power steering? I installed the Prius electric assist in my build, total cost was about $60 and a 4 hour install.
