engine mods for D15B4

[honda_gurl]

Hey,
I woz wondering if ya'll could help me out here. Im a gurl who knows nufin bout cars, but hell wanna learn more to modify up my car. Currently I got a honda civic GL 1990 with a D15B4 engine. Is there any possible way to modify my engine up a bit more, coz at the moment, its pretty crap... n I have no idea where to start!!!

i dont think you should both as u'd be just wasting your money for that engine. if you must, go with the really really basic mods such as air filter. for your car, take out the original paper filter and stick a reusable panel filter such as k&n or unifilter... i wouldnt bother with other mods :)

Don't waste your money on that engine, save it for a better car....or just swap in a K20A....Hahaha...just kidding.

Gees people. Not everything costs hundreds of dollars. I agree that it's not worth spending lots of money on it. But there are some things you can do that might give it a bit more zip. If you don't mind getting your hands dirty.

Like someone so subtly said above, this has been asked before though. Have a look around.

Make sure the car is running well. Just normal things, good cond. sparks, air filter etc... Get some carb cleaner onto the carbs. Maybe get the carbs tuned.

Some relatively easy mods you can do to the carbs for basically no expense (unless you stuff it up) ;)

You should check out ebay motors. Do a bit of research, and find out what US model motor is equivalent to yours. For example, the D16Y4 (ozzie model) is the same as the D16Y7 (US model), however the intake manifold for the D16Y4 is better (the same as used on the US D16Y8 SOHC VTEC).

Have a look, there are lots of things you can get, just don't forget to ask if the ship to Australia, and if so, how much for shipping (don't forget, this is all is $US).

aiights, i know its a crap engine...but worth a try seeing if thur woz nething i could do to it...i guess i hafta save up for a better car...thanx for ur opinions!!

Before you mess with the carbs try a lightened flywheel, some headers and a quick shift kit....that should give you some satisfaction.

I agree with KT.

Take off your existing intake, and wack on a K&N pod filter for easy breathing. Next some xforce or simular headers. Get a 2" mandrel bent catback exhaust and a strait through muffler.

Then make sure your running 98 octane fuel and advance your timing slightly by rotating your distibutor. Get your carb(s) tuned. And your car will be a zippy little beast. Also some new spark plugs, leads and a full service wouldn't go astray.

Furthur modifications include Clutch and flywheel, as well as a camshaft regrind. Getting your head milled and ported and polished. Maybe putting on a D16y1 or y8 head for SOHC vtec. then getting a cam and parts for that thing.

But if your set on your little D15b then there is plenty of options. Goto www.d-series.org theres plenty of yanks there who are running D15b non vtec motors which get 13s quarter mile times.

But first things first Intake, Headers and exhaust.

i got a d15b4...
prolly not best to get a pod for a carbie car, u can get ramflo or mushroom filters.. they do a way betta job than a pod.. pods are made more for fuel injected carz,

My GF & I only recently pulled the D15B4 Dual Carb motor from her 1990 ED Civic.
Good little motor and when tuned right can make some decent power. A set of extractors & a 2" exhaust will let the motor breathe better but more importantly if U decide to upgrade the motor at a later date, these parts can carry over.
Replacing the Fuel filter, Air filter and spark plugs is good, remember to disconnect the battery for a few minutes to let the ECU clear any faults. Yes, there is any ECU hidden under the passenger side carpet, under a metal plate with 4x 10mm bolts holding it down.

We fitted the Fuel Injected Japanese Import D15B VTEC motor which makes 130Hp standard compared to the D15B4 100Hp. I know of an importer who can get you the D15B VTEC motor & P08 ECU for the engine swap for around $900 plus freight. Best part is this motor literally bolts in and keeps the police happy as it only qualifies as a head swap(cause it is still a D15B series motor!!)
