so exactly what needs to be done to drop b series motors in HF crx's? I'm thinking about selilng my si and buy me a HF or DX (ac and i hate sunroof). thanks in advance!

Jeff-

 

HF has basically the same wiring as an Si, that isnt a problem. THe only real pain, is that the spindles have to be swapeed out since the HF uses a different spline on the outer axle joint. DX is the real pain because it has to be wired to use MPFI from DPFI

 

so what do i need to do the conversion on say..dx/hf?

Jeff-

 

if its a dx, u need to switch to MPFI.

 

swapping out spindles is A LOT easier than wiring dpfi to mpfi

 

yes
and its not that big pain at all
i did all the wiring in about 2 hrs....

 

any websites on how to do this?

Jeff-

 

While you are at get 90-91 ex sedan spindals and get 10.4" brakes, or add 92-96 prelude vtec rotors and 91-94 accord wagon calipiers and get 11.1" brakes. That's what I did.

 

si and hf wiring harnesses are the same
if u are using a nonvtec u will need 90-91 integra distributer
si steering knuckles
90-93 non vtec axles they made a gsr in 92-93 so dont get those
motor mount kit
90-93 non vtec upper lower coolant hoses
either buy or make your shift linkage if u wanna buy it call hasport
do your self a favor and try to find an A1 tranny

my crx has 81.5 endyn pistons
stock rods, cams, head intake and a hedder
i ran a 12.37@109 in the 1/4 7.97@91 in the 1/8
non vtec is the way to go if u are on a buget
good luck man

 

i have a 89 dx with a b17 swap(93gsr) i used the same axles and spindles that came with the gsr. why only non-vtec axles? mine work fine.

 

just get a hf and get ex/si/dx knuckles...other than that...you'll need everything you normally need for a bseries swap into a si

 

HaHaHa jeff, just save yourself the trouble and get an Si. Why an HF? Wanna save on weight?

 

I have si...but I want hf for the following reasons

(1)weight
(2)hate sunroof
(3)i want a black crx now
(4)ac

I'll echo some things said here:

Get an HF.

I work at a shop that does only Hondas, and we've done plenty of swaps into the 1988-1991 Civics and CRXs.

It is so much easier to swap front knucles onto an HF than it would be to rewire a STD or DX from DPFI to MPFI.

I have a co-worker who did this in his car, and he took a good while doing it. While it looks factory now and all, it did take him some time and he is very good with car electricals.

I would not want to undertake the wiring from DPFI to MPFI - that's just me I guess, but the front knuckles are so easy to swap man.

Good luck, and by the way, that extra light-*** HF body can't hurt performance now, can it?

 

DPFI to MPFI isn't that hard. Once you've done it time or 2 it becomes easy. Just learn how to solder and it'll be ok.

 

You won't be able to keep A/C if you do HF and B16 together, I have this and you might be able to just be ready for one hell of a headake

 

And why is that? Does HASport not offer a kit to keep A/C in the EF/ED regardless of trim level? Why would just the HF be different?

Am I missing something here?

The guy at my work who did the STD to SiR wiring also did his own custom A/C bracket and his A/C blows 32 degrees on cylcle!

 

the hf doesn have an ac button.. nor is insalled with the factory ac crap...

 

all I am saying is that I did this swap and I have no room for A/C and if I wanted to keep A/C I think it would be a bigger headake then what it was worth, also I don't know what you what to do with the car if it daily driven or auto x or show or all the above.

I am just saing that good luck with installing it and have fun.

 

Mine had A/C

 

Wrongo, mine had a/c as well. Of course I ripped it out, but it was there

 

I wasn't trying to be an ***, but it looked like you meant that just the HF model would not support A/C.

Correct, but if we want to get technical then NONE of the 1988-1991 hatches has A/C from the Honda factory.

Once they rolled off the trucks and into the dealers though, many of them recieved the factory Honda A/C before customers ever laid eyes on them.

This is also true for all the 1992-1993 Civic hatches - even the Si.

I know this from working at various dealers and having a 1992 Si that wasn't equipped with A/C from the factory.

My 1992 CX still has the original A/C "block-off" button where the dealer never put Honda A/C in.

 

I was not tring to be one either this is why I hate the internet because no one can hear the tone of my voice. So I hope that we are cool and lets drink on

 

back for you being a dumb *** and reply back w/o any sort of knowledge. I have a b16 in my 90 si and I *KNOW* it can be done w/ AC considering I can import the WHOLE EF8 clips if I want to.

Headache? What's not headache when it comes to cars?
