99 SC300 With A W58 5 Speed Trans.
I just got my hands on a 99 SC300. I am going to install a W58 5 Speed Trans in a week or so. I had the whole conversion with rear end and all the parts for the swap but in a little mix up I no longer have the rear end. From what I know the 99SC300 comes with a 4:27:1 Final Drive Ratio
The 5 Speed comes with a 4:08:1 Final Drive Ratio. Would there be much lost in performance?
Thanks For All The Help

I am running the 4.27 gears on my SC400 (3.92 from factory). The shorter gearing took ~0.4s off my 0-60 and 45-65 times. The car revs higher on the freeway, top speed is diminished, and the speedo reads faster that I am actually going; but, the performance gain is tangible.
Short of having a big turbo that is only offering boost for 2-3k rpm (needing a wider power band), the shorter gearing will increase performance by getting to and rolling through your strong revs more quickly.
A 4.27 W58 should be pretty snappy, but not so snappy to lose street manners. The MKIII Supra n/a W58 came with 4.30 gearing from the factory.

I have been waiting three days for that answer. Thanks (BLIZZY). The MKIII Supra n/a W58 came with 4.30 gearing from the factory. Would this bolt to the SC or could I just swap the internals into the SC rear end to get the 4:30 gearing?
I might be wrong but I did a 5 Speed conversion on the 95 SC300 that I just sold and I was under the impression that to do a swap on the 2jzge VVti the process would be the same. I might be wrong so if I am please CHIME in. I am going to start the swap this weekend if the weather is good.
