Im not sure how the others are saying no, because its unclear what motor you will be swapping in.

To clarify, you currently have a 91 with an LS and you will be swapping in a 92 LS or GSR?

If its a LS motor than it will be a straight swap.

It it is a GSR motor than you will ned the ECU and harness, or you can wire in the wires for vtec yourself.

the GSR and Ls motors are different? i thought they where both b18's

 

mostly the same but gsr has vtec ls doesnt. Also I dont know if ls has the secondary butterflies.

 

Wow,you guys need to search.

LS = B18B
GSR = B18C1

Mostly the same? Are you kidding me

The crank (stroke) is smaller, the rods are longer, the compression is higher, the head is different, etc.

Ali

 

Yeah I know it just didnt want to go into detail. For the ecu they are basically the same so the vtec and butterflies are the only differences.

correct me if Im wrong

 

Im not too familiar with ecu's and tunning and what not. But i would believe that the fuel maps will be different, higher redline.

Im sure im still leaving something out but whatever.

Ali

 

yeah im not familiar with it either except for the redline.

 

The maps and the red line and you also have that pesky little knock sensor to deal with , and i beleive that the vacums are slightly different and maybe the speed sensor???? but not sure on that,

 

how do i tell if it is a GSR ? will it say on the block?

 

you dont no what motor you have? wow, but in front of block it will say B18c1 if its gsr

 

it will either say b18c1 or b18a1
b18a1 will bolt and plug right in b18c1 will be a little more challenging

 

Wow Motor swap eh? And you dont know what motor ha
honda is so full of dumb *** ricers

 

yea i kno i dont kno much but im learning i havent been on the import scene long if u couldnt tell lol .....well thnx alot guys

 

well i gess u guys are not to familiar with the da and the db da isb18a1 db is b17c not a b18c

 

DA:
Ls, Gs, Rs motor : B18a1
Gsr Motors : B17's

DC/DB:
Ls, Gs, Rs motor : B18b1
Gsr motors: B18c1


there is a stamp midway up the Block on the far left side.....right were the block and the tranny mate, that stamp tells you the block code

 

first off all you guys should do some research before you give advice.From 1990 to 1991 is pre obd 1992 to 1993 is obd1 so on that note you need a new ecu and jerry rig your harness.also the easiest thing to do is just transfer your distributor and your injectors and your done so that way you can run an obd1 motor as pre obd

 

i didnt have to do a motor swap overall but i have to swap out the tranny

 

Wait, 91 integras are obd-0 and 92 and 93 integras are obd-1...isn't that true? Then ull need a obd-0 to obd-1 conversion kit and the obd-1 ecu or is that only if ur trying to run VTEC that you have to change the OBD?
