5 spd w/ short gears and 4.55 r&p vs 6 speed

[redshift]

Hi everybody,

I hope this is the right forum to put this... I'm getting a '93 manual NSX soon and I'm planning on upgrading the transmission - of course I'll drive it for a while first to see if I "really" want to do this. I have read the FAQ's here and a lot of other info on the 5 speed upgraded w/ short gears and the 4.55 r&p. I was just wondering what everones thoughts were on this vs the 6 speed route. Thanks in advance!

6 speed conversion great, but expensive....4:55 gears are no longer avail. unless you find a used set...I am having Titanium Dave in Oregon build me a 5speed with NSX type-r gears with the shorties...I think it will be the most affordable and still fun setup....my 2cents Brent :biggrin:

Short gears and 4.55 is too short IMO. I would go 6-speed all the way. (if money were no object).

NetViper - you think that setup is too short? Just curious why since I know just about nothing. Too much shifting... not enough top end? I'll be doing most of my driving around town and I'd like more pep, but I don't really high rpms (and loud exhaust) on long highway trips - would this setup inhibit me?

Texas91Brent - I'd love to know how much you're paying :smile: .

Here's is some info on how this set up works:

Short Gears and 4.55 #1

Short Gears and 4.55 #2

Short Gears and 4.55 #3

Somewhere in the 3300-3400 range...I also am building mine for around town. The stock setup, is too slugish for my taste...Brent :biggrin:

You could always do the Short Gears and the Type R 4.23 R/P. Thats what I have and I love it.

I agree. However, if money is an object, I wouldn't make any changes at all.

Here are the engine revs at 80 mph in top gear with the manual transmission NSX:

Stock '91-96: 3441 RPM
'91-96 with 4.55 R&P: 3854 RPM
Stock '97-05: 3168 RPM

(Note that the short gears for the five-speed don't affect revs in the top gear because they don't replace fifth gear, only second through fourth.)

Wow, lots of really good info. I think I'll hold off for now and just go the supercharger route. Thanks everyone!

You might find with the SC you don't need short gears as you will have a lot more TQ at the 1-2 shift point. I have never driven one setup that way, so that is just a guess.
