They also used a different header which contributed to most of the difference, not the valve springs. The 96 spec header was similar to the USDM setup (note same torque peak rpm). The 98 spec flowed considerably better and peak torque dropped. Much like when we install the JDM 4-1 on our USDM cars. Torque peak drops and we pick up a bunch throughout the powerband.

Not only that the 98 SPec was 19kgm(137 ft-lbs)@6200 while the 96 spec was 18.5kgm(133ft-lbs)@7500
So this along with the ECu added a bit more Torque and moved it lower.

No if you want to keep the torque on the low end you might want to kgo with a 4-2-1 Vs 4-1. Go with an exhaust no bigger than 2.25" Mugen Twin Loop is suppoesed to be goo to maintain torque as well, but I don't know that First hand

Not mentioned in this thread, but important to know:

TORQUE IS RELATIVE TO DISPLACEMENT

The only way to gain significant torque gains is by increasing displacement. Increasing the bore and stroke (as mentioned above) or forced induction is the way to go. You'll not gain much torque (mainly just horsepower) by bolt-ons or bumping compression with high-comp pistons and adjusting timing with cams.



EDIT: Some incorrect BS that I needed to set straight ops:

As before, what he said.
