Hello,

I need to pick some brains about this Civic. It belongs to a family member, and I'm always stuck fixing the problems it has. Right now, there is metal in the oil, and a knock starting. Looks like lack of oil changes, and an oil leak have put the little engine in it's place.

For whatever reason, one of the previous owners swapped in a D16y5 from a 2000 Civic DX/CX. This car is an EX so it should have a D16y8 in it, but sadly it does not. Seems the engine lacks power too.

I was looking at prices for a used replacement D16y8, but at this point, I don't know what was done previously to make the lowly D16y5 work in it. There is a check engine light for a code related to fuel tank pressurization... or was it charcoal canister pressure... something like that. Also, I installed a knock sensor and that code has gone away, just stuck with the fuel tank pressurization code.

What engine/trans can I swap in that would just bolt right up?
If I am going to replace the engine, I may as well put something in that has extra power. Was considering a B16 with VTEC, but how much trouble is that?

Thanks,
Triplelude

B16 swaps are relatively easy if you follow the proven builds and don't try to deviate from the instructions and parts list. Check the FAQ for links to those swaps.

From everything I've ever read about swaps the problems MOST people have with them is that they use parts other than what has been proven to work and they do not follow the installation guides

If your looking for Plug and play swaps, Try researching d15b. Its basically a y8 or z6, basically the same hp and tq ratings. I like them over the z6s and y8s.

B16 swaps, as said, are pretty easy. Just follow guidelines and write ups. Although going from d16 to b16 is not as direct(plug n play) as throwing another single slammer in there, still pretty simple.

TripleLude

So about how much money would I need to spend on parts to get the B16 swap done, aside from the engine, trans, and ECU?

Does it need axles, mounts, etc?

FYI it is an AUTO and needs to stay that way.

Automatic? Ugh. I think your B swap is out of the question. might just want to put the Y8 back in there like it's supposed to be.

where you located because I want your y5

Should have all the info you need in there.
Costs are probably going to have to be researched by you.

If it were me, I would buy Moog Axles. They have a lifetime warantee, that way if one breaks, or something of the sort, you can pop it out, take it to were you bought it, and they give you a new one, free of cost.

Youll need new mounts.

not sure on anything else. I would buy a harness, just to be safe.
Were are you planning on getting the swap from? Reguardless, if your wanting to keep it auto, youll probably have to buy the Engine and Trans separate. Most swaps come 5speed unless specified a different way.

I think JSA or Tiger offers Bseries (b16) auto trannys. Im not quite sure if an auto b18 tranny would bolt up or not, or if you would even want that to bolt up lol. Someone correct me if im wrong.

I'm doing searching still.

MyHondaIsSlow

auto tranny on a b16 is kinda...pointless, and most people will tell you the same thing.

In your situation i would just get a d15b, and throw a z6 or y8 auto tranny on it, and call it a day.

Auto transmission on a B16 won't fit anyway.
I'd only get the swap from here but they are currently sold out of them.

TripleLude

What about this motor. It offers the AUTO for $100.

What is the difference between the ZC's? Apparently this one has 137hp. Will it bolt in like a z6?

grumblemarc

iTrader: (4)

Sounds like a rip off and I've never heard of them. Check this.
http://www.hmotorsonline.com/shop/sc...age&item=30023
Doesn't offer the auto transmission but yours should bolt up with no issues but don't quote me on that. You already have an auto on it correct? If anything there might be an issue with the ECU.

You should call them.

Personally I'd just put another Y8 back in there.

98civdx

Your pretty much stuck with a D series engine.

Automatic B series engines are NOT any where close to a bolt in swap for 96-00. It will require a TON of work. example, cutting the frame for the trans to clear, a custom mount. Also, wiring the TCM doesn't sound easy.

IMO, It has never been done in a US 96-00 civic.

There were some in other countries that were auto B series, but they had different frame rails. Hunting down those parts would be very difficult.

If you want a B series you need to switch the car to a 5spd.

Libertariat

Wasting your time with an automatic honda.

End of story.

If you want fast and automatic you need to get a 96-01 trans am.

TripleLude

I don't want "fast", I just want to make this puny Civic faster.

I have my own built car with a 80-over cylinder bore that is fast and reliable (but not cheap). What I am looking for is easy power I can just drop the heck into this Civic without having to rebuild an engine.

Put the Y8 back in there. B-series and automatics aren't happening.

Libertariat

If rebuilding an engine is too much work wait until you have to tear apart the subframe and firewall to custom fit an automatic transmission onto the car.

Get an automatic v6 accord if you have to have a "fast" automatic honda.

It's not happening in a civic. Maybe a j-swap, but you'll be doing all of the above, tons of custom fab work.

98civdx

^ He speaks the truth. My car is a auto. Sure, it is plenty to keep on the high way with other cars, but from a performance stand point, it's crap.

The best thing you could do is either get a Y8,
It will be better than what you have, and will be decently quick, and still be able to net good MPG's.


I just saw you said Y5, someone correct me if I'm wrong but that would be a HX engine. DX/CX would be a D16y7.

TripleLude

Yes, it is also from the older HX.

I rebuilt the Honda engine I referred to, and it has a 5-speed. Currently, I am rebuilding another Honda engine bored 20-over that will mate with an AUTO. It will be sort of quick, but not as fast as it's predecessor.

It is not a matter of laziness or anything. Partly, this car belongs to a family member. I don't want to make a project out of it, so what are the swappable power options left?

You mentioned there are none. Ok so I am willing to hear out the next option. If I buy a D16y8, what do I have to do to get 150whp out of it?
- Crank: Is there a crank/rod combination I can use to increase stroke/displacement further than 90mm?
- Pistons/walls: How far can I bore this thing? 75mm is weaksauce. I'd like to see at least 81mm, like ITR pistons or maybe even CTR. My current build is Frankenstein ITR pistons, and it's predecessor has 83mm bore.
- Cam profile: Do I need to worry about valve springs if I get a wild cam grind done?

What helps this little D-series? No turbo or nitrous please.

Libertariat

The problem with honda d-series automatics is not going to be making power, but holding the transmission together.

Once you effectively double the WHP output of the D-series engine you decide on, your next goal to tackle is the cluster of clutches in the automatic transmission. They were never designed to handle the kind of torque doubling the WHP is going to put on them. You'll be going through auto trannies every 2 weeks.


Not to mention even with power, the long gears in the auto transmission is going to be the biggest handicap on the car. Lots of power + slow gears = slow car.

I can tell you right now you aren't going to ever make 150whp without a turbo or nitrous using an automatic transmission. It's going to cost you astronomical amounts of money and you'll get beaten by soccer moms in their GMC Yukons.

98civdx

Auto Honda transmissions don't like being ****ed with. They just want to be left alone and do what they were made to do.
There are a couple company's that make parts for the auto trans. But, when you see the price tag, you'd have a heart attack.

If you are thinking you'll make 150 on auto D and stay N/A, stop now. It's possible, but really isn't going to be easy.
Boost, or a large shot of nitrous are the only options. Keep in mind, if you spray that motor, your going to put holes in it.

Not to mention, there is no way that I am aware to tune w/ a auto trans.

There are plenty of people that have made 150 on auto's with boost, keep in mind the transmission/ torque convertor will not like that.

I would not go to 81mm on a D, ever. If you sleeve it, possibly.
Yes, if you cam the motor you should look into upgrading the valve train.

Everything that are saying is great, but not with a auto.

Save your self the trouble, and swap a 5spd in it. When you switch the enigne, that hard part is done. Short of dropping the peddles.

B16 is the way to go, more power and easy to make even more power

98civdx

Actually, no B16 is not the way to go.
He would be much better off with a GSR. Hell I'd rather have a LS than a b16.

Libertariat

I wish I had the money to dyno both a b16 with a b16 trans and an LS engine with a b16 trans and see which one makes more power.

Or better yet get some 60ft times.

I'd wager the b18b is faster.

98civdx

I think the B16 would make more power, but get owned when It comes down to torque. The b16 is a great motor for what it is, but there is much better motors out there.

A LS will a GSR trans, is a great setup. very under estimated.
