What engine do i have?

[89civic]

hi all, im new to these forums and was wondering how do i find out what engine i have, my car is a dual carb 1.5ltr civic GL sedan 1989

[Menthu Rae]

I can't tell you exactly where as I don't have a civic/know much about them - but the engine code would be imprinted on the engine block block, on my car, from memory- I think it's on the drivers side about mid-way down.

someone with a civic i'm sure can tell you where to look exactly :) or just tell you based on your description ^_^

[89civic]

very quick reply, thanks for the help

[krasyvy]

d15b7 or possibly d15z2

but yeh check ur engine code

[89civic]

so thats the crap engine isnt it, the engine code would be in the book or on the block?

[krasyvy]

on the block right next to where the tranny bolts on...

dual carb is no good, but can be modified if u know stuff about carbs...

otherwise swap the engine...

etc etc etc...

[89civic]

thanks for the help, i jus had a look and i think it says D15b4

[ECU-MAN]

Engine: D15B4

[iamhappy46]

D15B4 Dual Carb Emission Controlled SOHC 16 Valve... Around 75Kw from the factory.

Pretty good motor but they have a bad oil consuption habit after 200,000+K's

I suggest a 2" exhaust system and a decent tune up if you want to modify it.

thanks for that, my engine has about 245000km or something round there, it has started to surge when cruising and doesnt feel like it useto, any ideas

[iamhappy46]

Amazing enough, these cars have an ECU. Lift up the passenger side carpet under the dashboard. You will find a metal plate with a round hole in it. When the ignition is on, check to see if the red light inside this hole is flashing... If so, you have a fault code stored.

I would guess that the Exhaust Gas Oxgen(EGO) Sensor in your exhaust manifold is contaminated, that your mechanical fuel pump is playing up or that you have not replaced your fuel filter/spark plugs in a while... Most likely the fuel filter or spark plugs.

Fuel filter is located on the fuel tank, behind a black plastic cover. Couple of 10mm bolts to get it out and about $8 for a new one from most auto part stores.

hey, thanks for the help ill check that out and let u know

[89civic]

i checked the ECU and it does have the red light flashing, what should i try fixing first?

I suggest you ditch it and get a b series :thumbsup: d15b is sooo slow and eats fuel like crazy

[89civic]

yeh i agree with the fuel prob, im still on my learners, but i wont be doing anything to it except a stereo, mum bought the car for me so im happy with that, would be good with that engine though costs too much

[KB]

keep the d15b

Rip off the old intake and put some mini K&N pod filters, strait off the carbs. Get a nice header and 2" mandy catback exhaust. Then get someone to tune the carbs. Will run sick!

[89civic]

how much will that all cost, me and my mate drive round in it a bit so it would be good to have a bitta extra power but dont wanna be spending heaps on it

[KB]

450 for header

3 hunge for catback

umm and prolly lik 120 for two air filters

[89civic]

where do i get a catback from that cheap, i saw headers on ebay for 250 or so, but midas quoted me 280 fo an axleback, is that right?

[KB]

midas = poo

Um well being from perth i cant answer that.
Header and filters can be bourght from traders on this forum.

[89civic]

ok then thanks for that i might invest in some filters, but i need an amp first:)

For the love of god, ignore the idiots that say "CHANGE TO B16 !!!12211one221" It's very expensive and hardly worth it in the end. You're best to ignore Everything they say.

[EuroDude]

To me it sounds like you rather a good audio system rather than beefy engine performance. Considering ur mum bought it, you probably dont wanna spend thousands on improving performance.

Get a decent audio system first, then think about the engine.
If you want a cheap but powerful subwoofer, get the Adire Shiva.

This sub is actually better than most brand-name subs, but at half the cost! Believe me, this sub is freekin awesome!
btw Dont get Sony speakers or Amps - they are terrible.
PM me if you want recommendations - I know this stuff ;)


A B16A conversion would cost thousands - probably more than the car is worth. You must ask yourself if its actually feasible to upgrade an 89' car. IMO you are better off saving your money for now and get a later model Si/Vti Civic/CRX with lower KM's, newer shape, and a faster engine that wont require $$$ to improve performance that you will be happy with.

hi, i already have a sub, clarion dual voice coil, SWR1283, im thinkin of getting the new 2006model monoblock amp

[iamhappy46]

Firstly, get the D15B4 motor running right.

Firstly, I would install a new fuel filter, located behind the black plastic panel attached to fuel tank, on the passenger side. Fit new spark plugs while your at it and your spending about $30.
Under the bonnet, find the fuse box next to your brake master cylinder. Remove the 10A fuse closest to the bonnet hinge for 5 minutes, then put it back in. This will reset your ECU. Drive it around the block a few times and then check to see if the red light is flashing again.

If so, let me know. The EGO sensor may need to be replaced(very common on these engines) and is worth around $70 for a brand new NGK EGO sensor.

[89civic]

i put a new fuel filter in today, seems to run a bit better but i only drove it around the estate, but no where near as bad as it was before, i had a major service done when i got the car wich was in august or around then, the plugs look fine to me, but should i change them anyway

[iamhappy46]

Spark plugs should be fine if it had a major service. Just make sure you reset the ECU so it can adjust itself to your improved fuel flow. Another way of resetting the ECU is to disconnect the battery for 5 minutes but means programming your clock & stereo settings again :(

[89civic]

yep i did the reset thing, the ecu did 1 flash after about 15seconds of the key turned to on, i turned the car off and back on again and it didnt do it again. so i should have no problems now?

[iamhappy46]

Sounds like it is all fixed!!
Check it again in a few days to make sure that it is gone for good, some times it takes a few days.

[89civic]

yeh its all fixed, thanks for all the help
