In our country(Cyprus TR) Drag racing distance is 300Meter(shiitt)...
I try to select best tranny for this distance.(k20/24 EG about. 280whp)
Or any combination idea .. Final drive selection ?


-K20R Transmission 4.7 FD helical LSD (shorter 4th & 5th than k20a2)?
-5 Speed Rsx base(Integra type s(not rsx types) in our country)with 4.7 FD & Type R LSD swap(maybe B series LSD)?
-k20a2 RSX-TypeS or EUDM Type R transmission with TypeR lsd and 5.06 FD ?

Any idea ... any combination ?

you need to tell us an exit speed of a fwd car so we can figure out what would be the best combination..

I would say that you want to cross the finish line around 8000-9000RPM on 3rd gear

use the spreadsheet to try different transmission combinations and tires.

``I would say that you want to cross the finish line around 8000-9000RPM on 3rd gear``
This is very good information for me (special thank nikos).. . Because I really want to know finish at 3rd(at high rpm) OR finish at 4th gear(use close ratio final drive set at hi-rpm) is better for 300 meters.

I dont know exactly but i think will pass 300meters at 165-175km/h

i use -- www.teammfactory.com/gearcalculator.php --

So .. this is the figure at 8500 rpm with 195 50 15 tyres

RSX Base 5 speed Tranny with JDM R LSD&4,764 Final Drive Gear
1st -3.266 -61km/h
2nd -1.88 - 107km/h OR use Type R(type s) 2nd gear 2,13 -95km/h??
3rd -1.212 -165km/h
4th -0.921 -217km/h ALSO use CL9 Accord 4th gear 1.028 -195km/h(For ALSO good in 1/4mile)

And I can add 6th gear from CL9Accord for highway friendly..

Any other good idea ??
