This has been an ongoing project with one of my customer that i performed. It consists of a bisimoto h2d adapter.
h22 motor
bisimoto h2d tranny adapter plate
z6 tranny with quaife diff 5.0 final if i am not mistaken
rmf header
whale ***** intake lol
custom dss 2.9 axles
i performed this swap a little different from everyone else,instead of cutting the shock tower,i tilted the motor a little forward. i used a stock b20 tripod mount on the driver side,factory sohc tbracket,and modified a ek sohc tranny mount. the rear tranny mount required some spacers. i felt that the three mounts wouldnt cut it due to the torque,so i used the factory front mount and basically built a front cross member for it to attach to. i used a factory f20b single grooved crank pulley. the motor fits like a champ,is level,and the hood closes fine without any spacers on it.

good work man looks ****

 

Big thumbs up on that.

 

Very Nice man!
Good work!
Any times coming?

 

i would say a 4.9 FD, i dont know of any 5.0 but damn thats nice. I never really saw a point in the H/F2D swap unless you have a built D tranny. The ratios are damn near the same as an H tranny. But still i bet that thing ****in hauls ***

 

Nice, I'll just keep killin h-trannies though :-p

 

it was a mfactory 4.9 that was purchased thru exospeed

 

Very creative! I love the ingenuity here. Keep up the great work!

 

Props.

 

i know the pros of a h2b but what are the pros of the h2d if the h gear ratios are just about the same as the d trannys?

 

appreciate the comment bisi....and thanks again for the adapter...

a 4.9 final drive completely changes the gear ratios

 

supposedly the D's are more common, and parts are cheaper for them. thats what i've heard anyway.

 

**** with that you can get 50-100$ trannys

 

changing the final drive of a trany does not change the gear ratios. the rpm drop between shifts is still the same.

 

so you are saying if you put a 4.9 final lets say in a b16 tranny top speed doesn't change?or the engine doesn't rev any quicker?

please refrain from posting in this topic if you don't know anything about final drives

 

i see you reused the civic driver's side mount. how were you able to make this work? was it modified in any way?

 

haha, he didn't say that at all. He said that it doesn't change the RPM drops between shifts since the actual gear ratios aren't different.

 

good ****.

 

x2

do you feel as if the weight of the d-series tranny help compensate 4 the heavy h22?

 

VERY NICE! Props to another EK/H2D. Have you seen others?

Mine from 2006: http://www.rndauto.com/rantabuild4.htm

 

no modifications the tripod mount is a stock crv mount like out of a 1997 model

 

Can you give some more details on the modification of the sohc tranny mount and spacing of the rear mount. Do you have any close up pictures. Will this setup work for the f22 or F23 sohcs?

 

In which he would still be wrong. The RPM drop between shifts *would* be different. If you change the final drive, it is equivalent to either lengthening or shortening all of the gears by a predetermined ratio. What doesn't change is proportion between the gears.

Example - if you had a hypothetical transmission with a final drive of 4 and you were to reduce this final drive to 3, every gear would be 33% longer, meaning that the RPM fall on gear shifts would be 33% *more*. The amount of RPM fall between shifts isn't a flat number - it depends on the RPM itself because it is based on ratios. If you shift at 3000 RPM, the fall is half of what it would be if you shifted at 6000 RPM.

Another way to think about it - If you were to start with a Del Sol VTEC transmission (super short gears) and put in the 5th from an LS (highway fuel economy). Then you got all crazy about short gears and throw in a 98' Spec ITR final drive.
your ratios would be as such in the beginning
1st: 3.230 x 4.400 = 14.212
2nd: 2.105 x 4.400 = 9.262
3rd: 1.458 x 4.400 = 6.4152
4th: 1.107 x 4.400 = 4.8708
5th: 0.742 (LS) x 4.400 = 3.2648

and after you change the final drive -

1st: 3.230 x 4.785 = 15.45555
2nd: 2.105 x 4.785 = 10.072425
3rd: 1.458 x 4.785 = 6.97653
4th: 1.107 x 4.785 = 5.296995
5th: 0.742 (LS) x 4.785 = 3.55047

As you can see, every ratio, even the custom LS gear, has changed by a different amount, even though the final drive is one ratio. Basically the whole gearset changes by a given ratio, i.e. the proportion of the two different final drive ratios. Basically, each gear is 8.75% shorter, but since each ratio is different, that results in different changes. 8.75% of 3.23 isn't the same as 8.75% of 0.742. The result?

8.75% less RPM fall after each gear change. So the final drive actually has a huge effect on the amount of RPM drop. So, putting a Type-R (or even a B16) final drive in your old LS tranny could turn it into a very different animal.
