ok im having trouble finding out what all i need to make this swap happen....all i know for sure is to get the rywire jump harness.....what else do i need?....and someone said that i need 88-91 dx or si knuckles for the ls axles...please help i need every bit of info to make this swap flawless

 

also im takin the ls out of a 92 DA...will the knuckles off the da fit on my rex also will everything just line right up like linkege and mounts exc.???????please help

 

you dont need a jumper harness from rywire since its out of a 92 you just keep it obd0. yes you will also need dx or si knuckles because the hf's have a smaller axle. you can put da knuckles on but last time i tied it the front end couldnt be alligned right. you will also need after market mounts and linkage or cut the da linkage shorter. and youll need to beat on dent on the drivers frame rail for the alternator to clear. just search youll find a ton of info.

 

the 92 is a gsr witch is obd1

 

black0hatch is correct, don't use DA knuckles it will throw everything off. I did a 95 LS swap in my 91 STD. Here's what I bought:

91 civic Si Knuckles
90-93 Integra Axles
90-93 Integra Radiator
90-93 Integra Throttle Cable
90-93 Integra Clutch Cable
Hasport B-Series Motor Mounts (Cable Tranny)
Hasport B-series Shift linkage

Also, someone please correct me if i'm wrong but the 88 CRX HF is dual point fuel injection? a MPFI (Multi-point) conversion would be needed.

Good luck!

 

where can i get the mpfi at or is it aftermarket???

 

no hf is multi point but i think you need to change a couple dizzy plug wires not sure on that. and your title says ls swap but now its a old school gsr??

 

well its a 92 gsr that had the b17 in it well the guy before me blew it up so he droped a ls in it and thats where im at

 

well if its allready obd1 and complete its gona be cheaper to just buy the jumper. but you can run it obd0.

 

how dou run it obd0 without a jumper harness?

 

buy an obd0 ls ecu like a PR4. You will still need Swap mounts and a shift linkage. If you dont have access to a welder save the time and hassle and order a dependable shifter like a hasport swap shift linkage

PR4 ecus can be had less then $50
Swap mounts $200-$500
Linkage $100-$150
Spindles can be found anywhere. The best to use would be DX or SI CRX or Civic ones

 

yea its up to you whether you want to go obd0 or obd1. i suppose go whichever route would be the cheapest. it will run just fine either way.

 

ok im confused if i do keep it obd0 and get the pr4 ecu then how does the rest of the wiring line up like the distributor and what not please someone help i want it cheap and easy as possible

 

because its mpfi it should be plug and play just need the ecu as stated above, the axles and brakes( and mounts & shift linkage)

 

ok but what about the dist. its grey plug.aka obd1 how does that work remember this is a 92 obd1 ls...and about the brakes do i need the caliper and rotors??

 

what if i get an obd0 dist????????............so all i need is the pr4 ecu, mounts, linkige, knuckles and brakes right

 

and anything else like ball joints, if there out, as well as a clutch setup etc for swaping the motor over

 

ok so all i need is the pr4 ecu, obd0 dist., civic or si knucles, linkige, and mounts?????....anything im forgetting??? PLEASE HELP!!!!

 

i also have a question about the mounts can i or can i not use the motor mounts off the DA for the swap i have both the DA and the rex in mygorage....just wondering if i can use anything off the DA for my rex...anything at all would help ....and when i say anything i mean bumper to bumper the whole car lol sorry!!!!!!!

 

?????????????????????????????????????????????????? ??????????????????

 

you cannot use the da mounts.

 

ok do they have to be aftermarket or can i use some off of another car!!!????

 

must be aftermarket. no other vehicles stock mounts will allow you to run a b-series in an 88-91 chassis.

 

92-93 da is obd1

 

what brand would be the cheapest to getcuz hassprt is to high
