LexAnt,
Is the weak numbers on the 92-95 cars documented? It seems very optimistic for the same basic motor to increase 40hp from just a small bump in compression and different cam grind. Is it possible the dyno sheet for the 1st was a fluke?
I drove a 96 and did not notice much difference to the 93 also drove the same day.
Thanks for the info.

I had a 30,000 mile 97 z-28 camaro advertized at 285 H.P. I beleive except for the soft takeoff torque converter, my 95 sc4 has as much or more real world H.P. Back to the question at hand the distributorless ignition of the 98-00 is a major selling point to me as well.

Personally, I think 92-96 sc300/400 don't look anywhere NEAR as modern/clean/smooth/stylish/updated as the 97+.
Side skirts, front bumper, fog lights, rear bumper, extensions, rear spoiler, wheels, tail lights, cluster, 98+ gated shifter, etc- IMO are all noticeable and significant improvements that make the car look noticeably better.
Also, the extra boost in power/torque is always a plus![Cool](https://www.clublexus.com/forums/images/smilies/cool.gif)
220 hp at the crank = 154 rwhp?
that's a HUGE loss thru the drivetrain.. are these figures accurate?

Actually I used the previous official number of 250HP and the dyno number of 176RWHP (Soarer Central or Planet Soarer). The 176RWHP comes from the V8 with a true 250HP, so I just used the same loss percentage and calculated it with 220 crank HP, leaving me with 154RWHP. It certainly does sound scary, but if you think of it as 30 less HP at crank, then 22 less RWHP is fairly reasonable though. This is all just speculation and calculation, maybe someone can confirm an actual number?

as for the 92-95 being underrated as stated by greyblitz, that's wrong. if you search for threads by jbrady, he did all the research into it. Apparently when they rated the crank hp, it was with tubing connected only to the headers (no cats). That's just one variable in the equation.
