Question Horsepower

Whatsup everyone a new to this forum stuff but i was wondering if you guys could help a fellow SC 400 owner. I have a 92 SC400 with 42000 miles. Question is what did Lexus change in the SC400 to make it jump from 240 hp, to 260 hp, to 290hp, finally to 299hp in the 02' SC430? I really would like to k

The 290HP was from the new engine with VVT-i and the 300HP was froma VVT-i engine with 4.3L. I dont really know what they did to go from 240 to 260. I'm asuming they're probably a few minor changes.

SC400's never had 240hp. Changes were from 250 to 260 in '96 and from 260 to 290 in '98, SC430's have 300.
