Depending on the trim your rex is, you may have to change your spindles.

If you're going OBD1, you've gotta wire it and get the conversion harness and dizzy to match.

Cherry picker.

Someone that knows what they're doing.

Save your time and do your timing belt before putting it in.

yea..... I agree. Make sure that everything is torqued down to the right specs

[EvasiveEF9]

AND CHECK YOUR ALTERNATOR!

* water pump
* oil pump
* axles
* obd conversion harness if needed
* linkage
* u may have to cut subframe if u are runin aftermarket header
* hasport mounts (eBay mounts do not put the axles at the right angle, ur axles and CV joints will pay the price
* axles

am i forgetting antything?

This is just a peeve of mine, but... Civics don't have "spindles." We have knuckles with hubs pressed in.

After meeting you, I wouldn't expect anything less! lol. PERFECTION!

But seriously... everybody here has pretty much ltold you all the bare necessities to a b-series swap.

Your going to run into some knicks and bumps, so take your time, research, and you'll be aight. Have someone who has had experience with you the first time through.

...just a side note... the WIRING wiil be the hardest part.

[EvasiveEF9]

...this'll be fun, now.

SPINDLES!

[Foxturbo]

thnks cuz i have a 90 lx and im just taking the parts i need off to swap for my crx and selling the car for 400. so im just trying to do the research and ask questions. baby j about those mounts i cant use the avids or could i cuz i didnt want to be cheap at it but i did want to make sure i can use them. also the rywire kits i was looking at them and to make sure i wasnt forgeting anything heres the list.

[Foxturbo]

obdo to obd1 ecu converter
subharness w/t o2 sensor
ecu jumper
obdo to obd1 dist. adapter

is this right? not trying to seem slow but im really new to this whole honda game and i really wanted to do this right instead of letting someone eles do it.

[Foxturbo]

p.s could i use the axles n linkage from the car to swap in?

[JDMJAYDC2]

yes you can use the axles i believe ask ben aka evasiveef9 as he has this exact swap in his ef hatch so it is all his territory with this. what trim level is your crx? hf, si, etc im sure he is going to need that info as well to say what you need or dont need.

ps the rywire kit makes this alot easier so if you have the cash i suggest you get it as i am going to do when i do my swap soon

[Foxturbo]

my trim level is si and i have the cash to get the kits but i want to make sure im gettingthe right ones and not buying ones i dont need thats all.

[JDMJAYDC2]

hmm if its a si then i think half of the work is already done for you this should be a easy swap then but like i said im not 100% sure ill ask json for you as he has dones swaps as well hold a sec bro ill pm him

[BABY J]

Still need Rywire conversion harness (just buy it, or one from eBay - trust me, I hate chasing wires). Also - grab a timing belt. ALso - get the dizzy from Distributor Kings.

What mounts are you using?

[Foxturbo]

i wanted to get the avid mounts on nopi but if they wouldnt work i have to buy the hasports. so that list i had was right? just add the conv. harness and as far i dizzys i cant use the one on my motor cuz i have two one i bought brand new.

[Foxturbo]

wait a minute isnt the 1990 lx teggy obd1 right?

[JDMJAYDC2]

if its pr4 then yes
just use all of parts from the car you are swapping over
now that i think about it you dont even need a harness just use the one from teh da you are using since your using the ecu as well

so really you need shift linkage, axles and mounts i would get the hasport as teh avid ones are a bit off but go within your budget you can always upgrade later

[JDMirza]

www.boomslang.us sells good conversion harness. l8r.

[Foxturbo]

thnks

[JDMirza]

Anytime. Just trying to help people out. ^_^

[Foxturbo]

quick question when yall say the harness from the teg. i have the engine harness that u disconnect from the car but do i need the one from the car where the ecu connects to or what?

[jfrolang]

If the engine is from a 1990 Integra it's OBD-0, and all this talk of OBD-1 conversions is completely unnecessary.

An OBD-0 B18A swap in a CRX Si is practically plug and play.

[EvasiveEF9]

Thank god, Jeff...

There's so much heresey in this thread, it's not even funny...

Let's straighten some things out.

PR4 can be OBD0 or OBD1
-1990-1991 Integra's are OBD0
-1992-1993 Integra's are OBD1

You have the option to go OBD1 or OBD0. To convert to OBD1 (which is easier to tune than OBD0, then you just have to buy a couple more parts)

Your EF is OBD0, currently

If you have an SI, it's already MPFI, and thus you won't have to do an MPFI conversion.

www.boomslang.us has a plug and play for the low-low seeing as you can get one for a pre-MPFI setup. Buy it. It's quality. It's cheaper than Rywire. This is ONLY if you plan to convert to OBD1. If you're staying OBD0, don't worry about it.

Your DA axles WILL work with your SI hubs. You won't have any problems. Direct fit.

Your shiftlinkage will NOT work from the DA. You will HAVE to buy a new one. Check Avid Racing for the low-low...or spend quality money and get a hasport. I purchased an Avid. I hate it. It works...but it's not quality. Get yourself the Hasport.

Your motor mounts will have to be purchased. If you stay with a cable transmission (what you currently have) then get the EFB1 (if I remember right) kid for a CABLE transmission. If you convert to Hydro tranny, get the correct kid. I purchased Avid mounts (I think) and I hate them. Spend the money and get Hasport would be my advice.

The above information was typed with the idea that you plan to STAY as an OBD0 setup. If you plan to go OBD1, please advise so I can assist you further.

[jfrolang]

You can modify the DA linkages to work in a B-swapped CRX, you don't necessarily have to buy aftermarket.

If you can cut/weld, shorten the DA change rod 2 5/8 inches, and shorten the compensator rod 2 3/8 inches.

[Foxturbo]

yessss thnk you soo much uve just saved me sooo much money

[Foxturbo]

im stayin obdo so thankyall so much and i have the ls for 400 if anyone wants to buy it just pm me.

[EvasiveEF9]

...you're selling the LS? I thought you were putting it in your car...?

And JFRO...I was trying to keep his install simple...LoL.

[Foxturbo]

im sell the ls with no motor n tranny and putting the motor inside the rex. thats y im selling the teggy for 400 bucks.

[EvasiveEF9]

Oh. Well, when you say "LS for sale" make sure you make note that it's the car...not the motor...

[Foxturbo]

lol k

[blaknoize]

If the engine is from a 1990 Integra it's OBD-0, and all this talk of OBD-1 conversions is completely unnecessary.

An OBD-0 B18A swap in a CRX Si is practically plug and play.Wow really? Looks like that'll be my first swap attempt.

[EvasiveEF9]

Wow really? Looks like that'll be my first swap attempt.
Do it once. Do it right. Build it how you dream.

Anything shy of that will leave you pissed off at yourself.

[jfrolang]

A B18A is a great and inexpensive swap. You know this Ben, you have one. I don't assume that you will have one forever though. Few of us have the cash to go from stock to a built Turbo K24 all at once, we move in stages. A B18 is a fine first step.

[Foxturbo]

thanks im just using what i got unless anyone feel like donating lol

[EvasiveEF9]

Yeah, but my advice is to go ahead and get OBD0-OBD1 conversion outta the way, at least...

[1kreationz40]

ok i have the motor,tranny,the pr4 ecu, what else i need to get this done. plz help me out.

If you got a b18a, not a b18b...then everything mounts on, meaning, axels, and wire harness only...holes and so on...things u be needing is just shift linkage unless you cutt n weld....and aftermarket motor mounts, things u could only use from the DA is the axels...rear bracket mount and wire harness...be a easy swap.....!

[Foxturbo]

thnks

[EvasiveEF9]

So...?

How's the build coming?

[Night Ridaz]

hey how yall doing. due to the fact i got bit by a spider 4 times i havent been on but now here's an update. I put the rex project on hold for awhile cuz of the weather but now it seems that race season is coming on im going to put it together probably this month cuz i need a clutch n a axle.

[JDMJAYDC2]

why didnt you just move so you didnt get bit 4 times?

[Night Ridaz]

it was spontanious or however yall spell it lol but besides that the rex will be running soon. ill try to put up picts

[1flysi]

I'm surprised no one posted up about denting in the frame rail for alternator clearance purposes and making it easier to change the belt.:goodjob:
