[QUOTE=jdm_overdose;2110478]Im doing the exact same swap into my 1990 DA. all you need to do is extend your fan switch wire from your DA harness.
You can use the b18b intake manifold, exhaust hamifold, distributor, alretnator, starter.
IF you want to, you can change your ECU to 0bd1.
Nothing else. People dont know what they are talking about.[/QUOTE]
[QUOTE=90DB1T;2111086]i actually just did this with both obd1 (current) and obd2 (spun a bearing after 54.1 miles :() b18bs into a 90 DB1.
the fan switch is in a different location then original. 90-93 is in the back of the block, the 94-01 has it in the t-stat housing. how you convert this is up to you. other then that, the sensors are in the same location. well other then the o2, but thats not dealing with engine sensors :D.
if your going to use the b18b intake manifold, your going to need to add a few vac lines and splices. if “clean” or “tucked” is your look, this isnt going to be for you. for ease, i would suggest you stick to the b18a intake manifold.
the best place for you to get an engine in norcal, by the way, is engine world (in emmeryville) or attarco (in richmond). both will be far cheaper then any engine shipped up from socal. both those places offer free shipping (locally) and 6 month unconditional warranty. they will ask for a core though, as long as you dont have a whole in the block you should be ok. even if you do, the core charge + new engine is far less then one from hmotors ;).
as far as transmissions go… to be honest, i would rebuild the one you have. this will be cheaper for you in the long run. automatic transmissions are finicky and are often very misused. getting a used automatic is probably going to be a headache, if it even works.
so my advice:
used b18b from engine world ($713.36 dropped to your door step)
rebuilt autotragic transmission[/QUOTE]
Great post, reason why I mentioned the OBD0 manifold was simple, ease of installation.
You can use whatever you like actually, you can even modify a stock B16 manifold to work. Anything is possible, people just don’t know WTF is up though.
