Between the two, Supra mklV N/A and the SC300, which is faster? What is the power to weight ratio for both and which is faster in the quarter mile? thanks guys.

 

This is a good article(below) that compares the two cars(Supra 5-speed vs. SC300 5-speed) and shows the stock specs for the SC300. The power to weight ratio for the Supra(NA 5-speed hardtop, 3215lbs) is 14.61 vs. 15.7 for the SC3 5-speed. The 5-speed Supra does 0-60 around 6.5 and the SC3 5-speed does 0-60 in around 6.8. To answer your question the NA Supra 5-speed is quicker than the SC300 5-speed and is also probably faster.

SC300
Stock Specifications sourced from Car and Driver December 1994 issue

Highs: Sexy sheetmetal, sports car sting, the pinnacle of cabin decor.
Lows: Seems out of place with these sports bar brawlers (Supra, 300zx, M3)
Verdict: If elegance ruled, this car would be king

Highlights from text: "Interior is truly beautiful. The seats look like they belong in a living room, and expensive one." "Body styling-
SC300's svelte shape is Cary Grant - dapper." "The Lexus tends to get tail happy if braking is carried deep into a corner or the driver
lifts throttle suddenly mid-turn". The Supra with the same chassis has wider tires in rear with no comments on tail happiness. Oddly
enough, in this test, the Supra is awarded a perfect 10 while the long time handling champion BMW M3 (widely believed to be the best
handling car ever) handling only receives a 9. I guess that would mean these vehicles (SC300, Supra) have some awesome potential.
