I am going to put a b20b into my 97 dx
parts i have
JDM 20 motor with ls intake manifold
ls tranny and shift linkage.
20b timming mount
Si Left mount

My questions is what elso do I need?
what kind of ecu
what kind of harness jumper
what kind of starter

I did use the search button but only found info for pre 95 civics

Thank you for your help in advance

 

Using the "search" feature would help you, but i'll give you a heads up. 1st off, its exactly the same as installing a LS motor (B18B).

You will also need a 99/00 Civic Si rear engine mount bracket, a integra throttle cable.
For my setup,i got and obdI harness conversion and run a PR4 ecu.

 

u will also need a b20 intermediate shaft/ halfshaft. 94 and up integra's wont work.

 

So any pre 94 integra shaft/ halfshaft will work??

Gee, funny you'd say that....cause thats exactly what i'm running and it works fine, so thats not true. You do know that externally, both a B18B and a B20B are "identical"
Even internally, they use the same crankshaft and rods....the only difference is piston size (81mm vs 84mm)


Here's an engine shot of my swap

 

yup i got a b20 im my 96 coupe and im running a ls intermidate shaft and axles....almost everything is ls and as far as the mounts go the only thing i had to change was the driver side mount piece that is bolted to the block with those two bolts that are pointed at the top the b20 one made my motor gangster lean on that side it sat hecka low, i just got a ls one.....good luck and enjoy the wheel hop

 

So the b20 mounts work but the one thats on the drivers side right? you just got an LS mount for that side correct also where if you have any parts for sale get at me I live in the bay too

nice

 

yeah the driver side, not the cylinder shaped mount with the rubber on top but the bracket that mounts to the block, i dont really have anything usefull i could sale you cause everything i have is stuff your probably gonna take off......oh yeah you will have to get a ls intake manifold,throttle body, fuel rail i got mine at a local parts yard for like 55 for everything.....

 

What yard did you get them from my friend tolled me attarco but if you know a better one let me know

 

H.A.P in sacramento.......there pretty good thats where i get most of my stuff from or california dismantleing in american canyon

 

pr4 ecu.

 

i used the 97 integra halfshaft. worked just fine. runnin b20 with t3/t4

 

so the rear SI mount is not needed?
let me see if I got everything correct crv rear mount, crv transmision mount and Ls driver side mount.
Also they are the brackets not the round ones with rubber right
thanks

 

yeah the driver side is, its the mounting bracket not the mount, and for the rear mount yeah a si one should be ok cuase its for a civic coupe with a b series

i did not change my throttle cable, but i did mod the cable bracket.

 

Clean swap.
Is it the same power with the original b20 intake manifold?

 

From what I've heard you cant use the intake manifold because its too high and will hit the hood but correct me if I'm wrong as this would be helpful

 

yeah it will hit the hood........but i was gonna try proping the hood up in the rear like people do with washers to see if it will fit cause b20 TB is bigger i think....

omg....the pic i posted "is" the original intake manifold, obviously it fits just fine. Now its true that the 1st couple years of the B20B had the high rise manifold, that had to be swapped for an LS model, but thats a piece of cake and can be had dirt cheap at the junk yard.

 

either way the orginal posted mention he is getting a LS IM, and im running a GSR intermediate shaft myself with no issues. also.. i would suggest a better trans.. LS trans will make the b20 slow and sluggish

 

i have a obd1 jumper harness and a pr4 ecu with a dif map.

that ls trans is gonna leave you dissapointed. i had one at first then got a gsr. now im using a b16 tranny and wouldn't go back. unless you plan on going turbo and using a small turbo

I dissagree. 1st off, different years of tranny's have different ratio's. I'm running a 1999 LS tranny, which has better gearing than say one found in a 1995 model. My car goes like hell. I have serious traction issues already in 1st, i could only imagine how it would be worse with a b16a gearbox. At any speed in 1st gear, i can step on it, just with the throttle an start burning out, i would not consider the LS tranny to be a bad choice.
