if you want to get into detail about doing this swap here you go
if you have a 90 -91 b18a1 ls motor, your all set to do this swap if not
92-93 b18amotor is obd1. If its an 92-93 motor this is what you will need::
90-91 b18a1 integra wireing harness/or 90-91 d16a6 si wiring harness wrks
90-91 b18a pr4 integra ecu
90-91 b18a integra or civic si resistor box/if 92-93 motor use si box
90-91 b18a integra distributor (white plugs)grey plugs= 92-93
than there is wireing involved couldnt tell you what .. i did my swap into a 90 si so everything is there for me.
if you have a 90-91 ls motor than you see where your advantage is but than again loss of 10hsp from older motor.
-you need a mount kit simply from Hasport/Placeracing or simply search ebay
-shiftlinkage which i have and will sell for a 100 bills shipped.
-90-91 b18a integra axles ,also if hatch is not an si you will need integra hubs or si hubs .
-your b18a ls downpipe will not clear the civics catalytic converter. so two options,
make a straight pipe or purchase a highflow cat.
important
The most important things are on the drivers side where the alternator pully sits will need to be hit in with a 30 pound sledge wrks the best ! hahaha
Then where the rear motor mount bolts to the rear section needs to be bent down. For some reason the mount will not clear than trans if this isnt done.
Then the front motor mount will need to be completely removed.
This i believe is all you need, have fun adjust your timing to 20 degrees with a timing gun and go smoke gsr like theyre standing still.
