Hybrid Trans I've built / Hybrid Trans Ideas
Yes, I know. All of my non-honda friends are probably sick of me posting this stuff. But I always get asked "what do you suggest for my setup?" Now instead of taking the time to explain, I can just point people to this link (:
A few transmissions I've built. All trans calc'd with a 7500rev limit and 205/50/15s
########################################
1st trans:
1st = 3.250
2nd = 1.900
3rd = 1.346
4th = 1.033
5th = 0.750
FNL = 4.250
92-95 d16z6 1st and 2nd. jdm dohc zc 3rd, crx hf 3rd as 4th. d16z6 si 5th gear, d16z6 final drive.
gears end at following mph
1st = 37.28
2nd = 63.77
3rd = 90.02
4th = 117.30
5th = 161.55
70mph in 5th = ~3250rpm
80mph in 5th = ~3700rpm
Driving Impressions: A great all-around transmission. This is what the stock ex transmission should have been.
I later sold this to a racing team in california that was competing in the honda challenge. Buyer also bought my
0.878 zc 5th gear and advised that he was going to be getting a 4.73 final drive for it.
########################################
########################################
Second Trans I've built is for Chris "Batman" Bateman in California. This was my original idea for my "ultimate" transmission, but I later decided to go another route as I anticipated a future boost build :)
Batman Trans:
1st = 3.250
2nd = 1.909
3rd = 1.346
4th = 1.066
5th = 0.771
FNL = 4.928
96-00 d16y8 1st and 2nd. jdm dohc zc 3rd, 92-95 d15z1/d15b8 3rd as 4th. 88-91 civic dx/si 5th gear, mfactory 4.928 final
gears end at following mph
1st = 32.15
2nd = 54.74
3rd = 77.63
4th = 98.03
5th = 135.53
70mph in 5th = ~3900rpm
80mph in 5th = ~4450rpm
Driving impressions: Although I will probably never experience this setup first hand, I know how it will be.
This is an ideal all motor d-series trans. Owner can step down to say a 22" slick and as he builds his all motor
d-series, his rev-limit will increase. The idea is to barely top out 4th gear in the 1/4th Well Batman will be at
exactly 100mph @ 8000rpm in 4th gear with 22" slicks. This gives him some room to grow and he can fine
tune his gearing with slick size. Depending on how much power his D engine puts down, he'll then chose slick
size accordingly.
########################################
########################################
The next trans I've built is the "Bense" trans. I call it this because I'm the first person to test out these
mfactory 3/5 gears :P
Bense Trans:
1st = 3.250
2nd = 1.909
3rd = 1.565
4th = 1.259
5th = 1.000
FNL = 4.250 *see below
96-00 d16y8 1st and 2nd. MFactory 3rd, 88-91 civic dx/si 3rd as 4th. MFactory 5th.
gears end at following mph
1st = 37.28
2nd = 63.47
3rd = 77.42
4th = 96.24
5th = 121.17
70mph in 5th = ~4350rpm
80mph in 5th = ~4950rpm
Driving impressions: I love it. It's unbelievable. Everyone laughs at my third gear because it is insanely short. Take an ex 3rd gear, move it to the location of 4th gear, and get a custom gear to go right between stock ex
2nd and 3rd. 5th is insane on the highway, but I don't care. With my drive to spartanburg I got 28mpg. I took the trans off to change some stuff with it and put a stock d16y8 trans on. Gas mileage was so close I couldn't tell a difference. The thing I like about this setup is that I can easily put in any stock final drive in, much like the quaife B16 kit and change my gearing. For boost I could put a DX final of 4.058 in it :)
########################################
########################################
Next trans that I am contemplating building now that Mista Bone and I have figured out how to run a cable final drive. I call this trans the holy grail oem trans. Because it is pretty much the best you'll ever get with
strictly oem parts.
Holy Grail OEM Trans:
1st = 3.250
2nd = 1.909
3rd = 1.346
4th = 1.066
5th = 0.878
FNL = 4.4375
d16y8 1st and 2nd, jdm dohc zc 3rd, d15z1/d15b8 3rd gear as 4th, zc 5th, jdm zxi final drive.
gears end at following mph
1st = 35.71
2nd = 60.79
3rd = 86.22
4th = 108.86
5th = 132.17
70mph in 5th = ~4000rpm
80mph in 5th = ~4550rpm
Driving impressions: Don't know yet :) 2nd gear is shorter than my "Bense Trans" which might be more ideal
for a lower speed autocross track.
########################################
########################################
And last but not least, the SCHardbody Trans. I build this trans for my buddy Lee.
SCHardbody Trans:
1st = 3.250
2nd = 1.762
3rd = 1.250
4th = 1.033
5th = 0.702
FNL = 4.250
He started off with a d15z1 trans and we placed an ex final drive in it, ex 3rd gear, and a hf 3rd gear as 4th.
gears end at following mph
1st = 37.28
2nd = 68.77
3rd = 96.93
4th = 117.30
5th = 172.60
70mph in 5th = ~3050rpm
80mph in 5th = ~3450rpm
Driving impressions: First thing I'm going to say is that this trans isn't "perfect" There are better gearing options available. This is a complete budget setup with parts that I had left over. The only thing is we had to
spend $25 for the hf 3rd gear as 4th. Lee had a d15z1 trans which is insanely long gearing. Anything is better than stock cx/vx gearing. Anything. So rather than getting ahead of ourselves and spending too much money on gearing, I came up with this cheap setup. It's better than a stock ex trans from a roll, because the taller 2nd gear takes him further into the shorter ex 3rd. The shorter 4th gear also helps out. If I were to make one
change to this trans I would have thrown in a 88-91 civic dx/si 5th gear of 0.771 in it to help out with the gap from 4th to 5th. But who cares, it's not like lee will need to be accelerating past 117.3 mph :)
########################################
########################################
There's also the trans that I built for Patrick (thehatchninja) This is a "classic" setup.
Civic ZC/Si hybrid
1st = 3.250
2nd = 1.944
3rd = 1.346
4th = 1.033
5th = 0.771
FNL = 4.250
ZC 1-5 gears are short with a tall final drive. Si 1-5 gears are long with a short final drive. We left the taller
Si 5th in for less highway rpms.
gears end at following mph
1st = 37.28
2nd = 62.33
3rd = 90.02
4th = 117.30
5th = 157.15
70mph in 5th = 3350rpm
80mph in 5th = 3800rpm
Driving Impressions: Read about my 1st hybrid for further details, the setup is very similiar. I sometimes
wonder if the honda engineers intentionally gave that zc transmission those shorter 1-5 gears to "sneak" the
mass production of "performance" gears and just gave it the taller dx final drive so that the trans seemed
normal. Those DOHC ZC transmissions are great to scoop up to improve acceleration :)
