Default F20B swap

Ok so I've decided to go with an F20B for the Del Sol, seems like a pretty disgusting motor for the price I found one for :D, anyways, I pretty much know everything I have to get to do the swap, the one thing I'm unsure on are axles, will my factory stock axles (For a D16Z6) mate up with the F20B trans, any insight whether good or bad would be appreciated, thanks guys

OP, I'm nearly 100% sure you can't use your d-series axles. I've never swapped an H22 or F20b but I'm pretty sure the swaps themselves are nearly identical when it comes to what you'll need. Look into what others have used for axles when swapping an H22 or F20b. I've read that it depends on the mounts that you go with but I don't know the correct answer, so try searching and you should be able to find out for sure.

You'll need axles that fit your transmission.

Edit: Since you got such a good deal on the engine, you should save some more and go h2b.

You'll be a lot happier with the car once finished.

it doesnt need to be h2b for you to enjoy it. i was more then happy with my h22 swap when it would stay nose to nose with 02ish vettes.

im now in the process of swapping in the f20b as well, i went with hasport mounts and axles but i would definately look at dss axles do it right and never have to worry about it again!

edit: theres nothing wrong with the hasport axles, but if your planning on putting some power to them i would definately go with the dss axles.

I like h2b, since I have always been a fan of not cutting up the chassis for shifter boxes, and mounts. However if you got the t2t4 trans with it, it should make for a fun car...

H2b is only like 5 times better than a regular F/H swap with their respective transmissions.

I guess you don't know just how bad H-series cable trannies are compared to a good B-series transmission.

really? turns out i have had a d/b/h and truthfully i prefer the feel of the H so thanks for telling me what i know though, quite helpful!

and when im done converting the hybrid racing k-series box and cables over to the H there wont be any hacking at the chassis for the shifter assembly whatsoever.

with the stock H shifter it can feel vague but with some simple bushings/ true short shifter the H series feels much more defined then the B ever felt.

OP do what you will but try not to read to much into the people who read things rather then look past the people who have tried things!

If you want to keep the axles D, there is the f to d kit from Bisi. This is my planned route since I like the thought of keeping my lifetime axles going LOL.

This is what I am doing with a 2.2 from a CL I yanked at the junkyard.

i never mentioned once anything about gearing, lets get technical here.

since the origonal car that the H came out of has bigger tires (23.9") then the civic your putting it in(22.7") a little formula can be applied to figure out your new FD

old tire/ new tire x origonal final drive=new final drive!

do a little math and you will find the H final drive comes out to a measley ,4.49 o wait thats higher then your b-series final drives.

and when you do it for the b-series it comes out just barely ahead of the H at 4.53.

so for the next question is for a little better and i mean little, is it worth the 500 plus dollars for the kit, tilting your engine forward like crazy and having hood clearence issues.

Yeah because we all know final drive means everything.

Why not just put the right size tires on and take advantage of a better tranny?

There's a better reason for the h2b kits than easier fitment and installation. There's also just as equivocal a reason for there being a distinct lack of d2h or b2h kits.

i prefer my car not to ride like a truck, and obviously final drives arent the final factor but aa very easy fix to gear ratios....maybe thats why there are so many companys out there that make them.

the ONLY reason there is a h2d kit is because people are cheap.

easier fitment? is that where you have to take a BFH to your framerail? or where you have to shave your block down?

seriously there is an equal amount of work both ways. H22 tranny you drill spot welds out of tranny mount and cut a hole in the floor(which as i mentioned before if everything works out soon i will have a solution to that)

and H2B you have to do as i mentioned before.

you need to remove your mouth from this bandwagons *********, and realize there is alot of potential in a full H/F series swap

I have a 5th gen Prelude and my F20B is being prepped to go in, and I would do a B16LSD or Type R trans if there was a kit to fit them in a Prelude. I've had B cars, an H22 LSD Teg, and the Prelude, and I like the feel of rod shifters better, plus I had problems with the cable's fraying on the H22 Teg. Also short gearing is the ****.

The Accord R H22 trans T2W4 has pretty good gears, but good luck finding one.

I'm surprised no one has mentioned the H-series poor axle angle yet. I've been told mount kits are getting better but at least at one point guys with H-series swaps used to go through axles continuously. B-series transmissions are tougher, you can say whatever you want about gearing, but as far as staying together the B-series is the clear choice, this combined with a factory fit and the ability to use factory axles means a lot.

Not to mention the aftermarket for h-series transmissions sucks.
