For 94+ SR20DE powered car, NA people swap 91-92 intake cam to gain
some reasonable HP's. Only intake cams are needed to be swapped out
because many have reported little to no gain by changing the exhaust cam.

Now, for turbo application, would swapping out my 95 exhaust cam w/ 91 cam
help?

Does NA people see no difference because the lift/timing are the same? Or
are the exhaust cams really different between early years and later years
SE-R's? And from this difference, if any, could turbo people possibly
benefit from better and/or smoother exhaust flow to propel the turbine
better?

Thanks guys!
