heh... being so used to how manifolds usually look, with all the extra stuff hanging on them... it looks kind of odd to see one all smooth.
It does look pretty nice though, and I'm glad to see ya posting up pics. Do you think this alteration will change the sound of the engine? I'm really curious what potential effects you'll get!! Keep us posted
Yes the motor will produce a completely different sound, but I don't believe the shaved manifold will attribute too much to that change. But the change wasn't entirely for cosmetic reasons.
I did port intake to 60mm to accept a larger 240sx throttle body, and I have been playing around with the runner size, but that won't make too much sound difference.
The difference will be the fact that the motor WAS naturally aspirated, running through 6-1 ceramic coated headers to a 2.5'' mandrel bent exhaust ending at a Dynomax turbo xl muffler.
The next time the motor will be spun over it will be turbocharged, with a full 3" mandrel bend exhaust ending in a Dynomax ultraflo muffler.
With the headers and the N/A setup, the sound was very race car, it sounded like "La Mans" my friends said. "Everywhere I went" (I have a sound clip in the "what do you drive" sticky at the top of the forum, or visit the link in my signature for another location of a sound clip.)
With the completely new motor and exhaust setup the car will be very reminiscent of a diesel truck at an idle, and the tone will be much much deeper, and not high pitched like the N/A setup. It's going to be cool to make the same motor make two entirely different sounds.
I'm going to head out today and hopefully get a chance to lay some weld.
Updates will follow.
