I'll probably be swapping in an SR20DET sometime next spring, but wouldn't mind playing with the GA16 for awhile before hand. Anyway, I've got a few ideas that I am interested in just looking at the engine and wanted to see if anyone has any background on any of it.

1st: Does anyone happen to have any data on the intake plenum volume and the runner lengths and diameter on the GA16DE intake manifold from the B14 cars? I was looking at one earlier and the plenum looked a bit larger and the runners a bit wider/shorter, so I was thinking about trying to fabricate a couple of adapter brackets to adapt it onto the B13 GA16DE that I'm using now just to play around. If the volume and runners are sufficiently different it might just be worth it for a little bit of high-end power.

2nd: As I was looking at the throttle linkages on the throttle body it occured how easy it would be to change the location of the TB unlike on some other cars just by replacing the brackets a little. This led me to wonder if anyone has experimented with larger throttle bodies with parabolic tapers to the intake manifold? A parabolic taper would tend to increase intake velocity of the intake charge, and that coupled with a larger TB would also allow the mass of the intake charge to increase as well. A simple 1-2cm plate adapter would be easy enough, and also provide a way to reduce turbulance by moving the greatest source further away from they cylinders and allowing the intake charge to smooth out. I'd think that this would be a fairly effective way of freeing up some power, and would be especially effective on a FI car.
