Euro-R accord or Accord Type-R H22a trannies are the best for acceleration:

Euro-R/Type-R Tranny:
1st: 3.285 61km/h (7400rpm => 4708rpm) [64km/h (7800rpm => 4963rpm)]
2nd 2.090 96km/h (7400rpm => 5244rpm) [101km/h (7800rpm => 5527rpm)]
3rd 1.481 135km/h (7400rpm => 5351rpm) [142km/h (7800rpm => 5640rpm)]
4th 1.071 187km/h (7400rpm => 5610rpm) [197km/h (7800rpm => 5913rpm)]
5th 0.812 246km/h [259km/h]
Final 4.266

4th gen is also good with a shorter first gear

M2B4 = LSD
M2F4 = Non LSD
Final Drive: 4.266
I : 3.307
II: 1.950
III: 1.360
IV: 1.034
V: 0.787
Rev: 3.00

5th gen

1st - 3.285
2nd - 1.956
3rd - 1.344
4th - 1.034
5th - .787
rev. 3.
Final 4.266

 

i make power to 8500 and i shift at 8850.

 

That's what I like to hear boss..I'm building my motor with an F20B crank, do you have a dyno graph? List of mods?

 

well all i have is JUN cams, i/h/e, HONDATA stage 2a and tuning. i make almost 210hp to the wheel. and about the dyno, ill try to scan it and post it.

 

satan...according to that the 5th gen has a shorter 2nd and 3rd gear?

 

Both Pro Drive ( http://www.prodriveusa.com ) and Houseman Autosport ( http://www.housemanautosport.com ) will make you a custom H22A final drive gear to your specs.

Thank you thank you. In the meantime where are your peak HP and Peak torque What times are you running so far?

No the higher the number, the shorter the gear. The 5th gen has a slightly shorter 2nd gear than the 4th gen, but barely...

 

I founf some ratios for some accord F series trannies that would probably work...i mean you're trying to select gears that maximizes the powerband of your graph right?

 

Joel:

Let me know as welll on those F series gear ratios.

Like I wouldn't mind the 5th gear from the S model hehe...

The F18, F20 and F22 JDM motors all have a 1.483 2nd gear for their auto trannies. I don't know anything about trannies, but I'll guess that you could use this as a 3rd gear, even though its auto?

Correct me if I'm wrong...

 

are those really the gear ratios for the euro-R tranny?

 

Yes they are, Accord Type-R as well.

Could you tell me the rpms you make peak hp and peak tq in the F20b? Or e-mail your dyno graph to jbycraft.hba2002@ivey.ca thanks.

 

The M2F4 is the 4g prelude VTEC tranny. Are you sure on the 5th gear ratios between the M2F4 and the 5g manual tranny? I thought the 5g had a taller 5th gear. Can someone with a 5g manual post what rpm their engine is at in 5th gear on the highway going like 60 or 70 mph? I've been trying to find out if a taller 5th gear can be swapped into a M2F4 tranny for cruising on the highway with the engine at a lower rpm. I know the 5th gear from a 4g Prelude S will not fit. I think the S tranny is the same as the accord trannies, so that won't work either. Has anyone successfully done this????

 

spoon final drive set.. those are bad ***..
