I cannot decide on what to do for an engine swap. someone had said a b18 is common... and less complicated than others.
i searched for a few hours, and could not find a swap guide... don't know much about the b18 either.

from what i know, it came in pretty much every acura integra.
i am looking at the b18b1 engine by the way... hoping it will please me.
i understand the obd0-obd1 conversion, get a jumper harness.
b series mounts too...

axles confuse me though. what would i need? shift linkage from an acura integra would work too? like, in the 94-00 era?

would getting a used engine from an auto wrecker be worth it? can i use the mounts from that car too? or is it just too unsafe?

this is hopefully going to be going in my 1988 crx si... i don't plan on boosting it right away, maybe next year, and after an engine rebuild. this is a summer car... so i want it to be somewhat fast. can i use the header+exhaust i have? i am pretty sure i will nead a new header... but just asking just incase.

don't tell me to search. like i said, i already did... couldn't find any good info. found a really good b16 swap guide though. http://www.crxresource.org/modules.p...rticle&sid=134
is it more worth doing a b16... seriously... moneywise to performance wise?

Check the link. Tell you the list of thing you need.

so about $3000 ish for a B16a swap. ok.

but i want to know about the B18b1.

D16SiHatch

the b18b1 would certainly be a good engine to go with, and yes i may be somewhat bias... lol. they do handle boost quite well (they have 9.5:1 compression stock). check out the nearly 800 page thread of just boosted ls's. you'll learn a lot there.

The b1 is pretty close to the performance of a b16a. has less hp but more tq, and it's available earlier on. b16a (158hp/111tq at 7000rpm) b18b1 (142hp/127tq at 5000rpm) mated to the same tranny it would be a drivers race most times.

For axles you can use 90-93 teg axles with the matching manual trans intermediate shaft. if you have a 94-01 teg or 99-00 Civic Si intermediate shaft then you'll need those axles. You can use a shift linkage from a 90-93 teg, but not 94-01. it would still have to be cut, shortened, and welded back together though to fit properly. otherwise just purchase linkages designed for a b-series into ed/ef chassis.

If you can get an engine for a reasonable price from an autowrecker, and some kind of warranty with it, then go for it. you can't use stock b-series mounts, you must use mounts specifically designed to drop a b engine into a ed/ef. You will also need to use the b-series header and downpipe. it won't match up to your stock cat though due to the bolt holes not lining up. so you'll either have to cut and weld the cat, or get an omni/blox adjustable test pipe.

so i can use 94-01 axles and intermediate shaft, but i gotta buy shift linkage and mounts...

ok. that makes sense.

i am just trying to compile a list of things to get. just the basics by the way.
- motor (b18b1)
- obd0 to obd1 harness
- mounts
- shift linkage
- axles, intermediate shaft
- header + downpipe

is that it? really? for the basics? oh, and an ECU... what works best really? the integra one?

ECU

OBD1 P75 or PR4
Also need the 4 wire O2 sensor

Canadian_EF

o2 sensor is on the header or downpipe, right? so if i just get that stuff from the auto wrecker, and use it for the time being, it should be fine eh?

"quote from D16SiHatch"

this is what you'll need

-90-93 Integra axles, 94+ pass axle abs,non-abs,auto,manual will also work
-90-93 integra MANUAL intermediate shaft
-obd0 to obd1 Ecu conversion harness w/ subharness
-obd0 to obd1 dizzy adapter, if you didnt get one with thee above
-DA throttle cable
-shift linkages (hasport, avid, innovative, ebay)
-Motor mounts (see above^)
-90-93 integra rear transmission bracket, must be from a manual

xaine

if you get a obd0 b18a1
you wont need to do any wiring stuff
just plugs up
but i prefer the obd1 swap. jumper harness for like 100
and all you have to do is wire the four 02 wires.

also you will have to beat down the front mount ears
and be running no front mount

you will need the clutch and flywheel setup to match the b series trans
you will need to have da or ef-si hubs to match axles

Canadian_EF

would i absolutely need to convert to hydro if i can find a gsr cable tranny?

xaine

you should just find a b series cable trans

D16SiHatch

gsr cable trannys are quite rare, but yes finding a cable b-series trans would be easiest that way you won't need the hydro conversion.
