Dedicated DA9 Q & A thread

[DA9-47]

hi guys im new,

I have a DA9 LS B18A1 5 speed, engine has 255 xxx ks on it and runs abit sick so i just bought a DA9 auto with an immaculate B18A1 with 160 xxx ks on it, so i want to take the engine out of the manual shell and replace it with the engine from the auto shell.

Questions:

# will the auto engine bolt onto the manual gearbox without cutting or drilling?

# is this nearly the same as converting an auto DA9 into a manual, but not having to worry about installing clutch and pedal? just go straight to the engine gearbox part of the conversion?

# is there a guide for this?

any help would be great
Thanks guys

Hey man, welcome
everythin will bolt up normally
only thing is, if there both series 1 or 2.
what year are the cars?
if both cars are same year, then its straight swap

basicly take engine out, take auto off engine,
take other engine out, take manual off, take flywheel clutch off. put flywheel clutch manual on good engine, and bolt it back in.
its a bit of work, if ur mechanically minded its quite doable,
also convertin auto da to manual, isnt easy haha, ive done it before
but a straight engine swap shud be fine.
theres a service manual on the web somewhere to, help a lil.
itll tell u how to remove engine, and torque specs.
while doin this id get a new clutch
but basicly if any of this worries u a lil, go to a workshop and get it done, but couldnt begin to tell u how much itd cost

hey dude,

cheers for the info,

i was thinking it should be straight forward, just needed sum expert DA9 advice =P

The year only really matters for which clutch you get, early years are different to the 92-93.
Give the engine a good service before you put it in as well, new seals, timing belt, water pump etc. Do it now and it can save a lot of mucking around down the track

i meant more for obd0 and obd1
clutch wont matter, becuz his using the same gearbox regardless

hi mooshie , both my Da's are '90' will be doing as much as i can to the engine before it goes in , besides timing belt, water pump ,oil/fuel filter,sparkies and leads, anything else you can think of?? and are there many seals to replace?

trying to find extractors and a bigger throttle body to slap on also.
i had a pipe welded up to replace the old intake when i got the manual DA9 3 years ago , but its the same length as stock box, so i was gunna extend it down through that hole under the stock box, is that the best place to have your pod?

thanks mate

i got the car manual online and printed it out, it's my bible atm lol,

hi guys =)
well to clear a few things up guys, both DA's are built in '89' , are same engine(B18A1) to the tee, bar the tranny, i have a heavy duty clutch in the manual gear box ,and it feels ok still, but i think i'll take your advice and put a new clutch in as i cant be bothered doing this twice. Now i've been trying my very hardest to understand the whole obd0 and obd1 thing and im not quite getting it.now i understand that if i swap a motor other than the original, in my case ill need to change my obd thing( lol soz) , but because i have the same engine , and they run off the same computer, i dont need to upgrade, but if i wanted to tune my car to suit the mods that i do/way that i drive, then i have to upgrade???, i was looking on the Hondata web site and they say i need to upgrade to a s100 or sumthing??
From personal experience guys, is upgrading my computer worth it? is it hard? and what kind of $$$ am i looking at??

thanks again guys

Duh, sorry forgot about OBD0/1. Stevo is right, should be a drop in swap if they are both the same year. I was only thinking mechanically not electrically

As for the computer, you only need to change that if you have modifications that affect the tuning. You will see a benefit even on a stock motor but bang for buck there are better things to spend money on first.
Personally I would get- CAI,exhaust, cat, header, cams, computer, throttle/intake manifold, internals etc etc. In that order. Purchase price is about $500 on an S100 second hand then about $600 for tuning

[stevo716]

if same year no need to change ur computer everythin will build up,
id change sump gasket, and check the rear main seal, not that hard to change,
then rocker cover gasket, and the spark plug ones, theres good kits in america for around 100 dollars that come with alot of gaskets
oxy sensor is always good to replace, even tho there lil expensive around 90 bucks if i remember correctly.
check the pipe at the back that connects from water pump to thermostat, if hasnt corroded that like to leak, pretty much check all the hoses see if there still rubbery if too hard change em, same deal with gaskets rele.

i can help with exhaust part of deal got one for sale hi flow and 2 1/4 piping

once u start moddin alot, as mooshie said, id only rele tune once u start changing internals such as cams, anythin that huge changes air flow, then its recommened to change to odb1
but with I/H/E, thers no need to tune

Good luck man
