Okay, for my reasons alone, I want to put a VX engine with auto trans in a 1998 accort coupe, the cool one. I have not done the HP ratio to the original weight of the car it came out of, so, not sure which exact motor I want to use. The VX engine, with its high MPG, is the first canidate I am looking at.

1) First, if I wanted to, could I put this in the car (physically) very easy with engine mounts and axles bolting up okay?

2) Since the VX engine is a OBDI engine, if I wanted to stick with a OBDII setup, which engine and auto trans would fit, and be equivelant to the MPG engine like the VX engine?

Note: I am aware that the VX engines gas mileage comes from having a stick and may not have ever come with a auto, but, an auto is where I am going with this project.

Thanks all.

 

High MPG goes out the ****ing window when you put it in a car with twice the weight.........

I have no idea why you think this is a good idea. Putting a 50CC scooter engine that gets 60MPG in your 1.5 ton Accord is not going to give you 60MPG.

92-horsepower engine in a 2100lb Civic that only got 35mpg highway (http://www.gassavers.org/garage/view/85)

Swapping it into a car with a 140hp engine in a 2900lb Accord (http://www.internetautoguide.com/car...ord/index.html)

 

it could be done. it shouldnt be done. if you want to see how well it would work, put 1000 extra pounds of weight in your vx and see how badly it accelerates and how much throttle it would require to maintain speed. that cvt will not last long. they didnt last in their original intended application for the most part.

 

Okay, first, are all you Honda people this disgruntled or what?

Second, I do not care if a car is one, two three or four times as heavy. Which engine is going to get better gas mileage, a 1.6 engine or a 5.8L blown V8? Really......I mean REALLY?? I know what does what in where and what to expect. Cripes, the CRX barley had enough HP to do 55 on the hgwy. If I want to pick an engine that barley gets my car to 55 on the highway, why yu yelling at me? Honda did it and everyone was cool with it, screw me, eh?? I judt dont get some people!?!?

Yes, I know they were lacking on HP. I just want to know if it fits easy, I have all kinds of options to up the HP or go another route.

Also, remember, I also asked for a OBDII equivelent. Once i get that info, I will start upping the HP accordingly. A set of headers and intake is supposed to get, from what I read, an extra 30hp. Is that enough? Maybe, dont know. As you can see, this is my first post, have a lot of figuring to do.

Anyways, back to the original question please.

 

Please go right ahead and swap in a torqueless monster 1.5L 4cyl engine and replace the already capable 2.3L 4cyl that's in the vehicle and should be getting around 27mpg.

You're not swapping a 5.8L blown V8 out for a 1.5L, you're swapping a 2.3L out in place of a 1.5L.

The CRX is ridiculously lightweight and doesn't require lots of HP to get moving. The Civic VX is another rather lightweight car (not as light as CRX) and doesn't need much power to get moving. The Accord however starts to get heavy and needs *umph* to move. You are in no way shape or form going to gain any power/mpg/highfives/skittles/puppies/girls/money by swapping in the 1.5L D-series.

You are a idiot if you still believe this is a good idea. I'm not going to sugar-coat your stupidity.

 

Civic VX (2100lbs) - 1.5L D series - 1 hp / 22.8 lbs with 98 ft/lbs
Accord LX (2990lbs) - 2.3L F series - 1 hp / 20.2 lbs with 150 ft/lbs

 

[what's with the trolls lately? some outrageous question, then immediately going on the defensive and making broad generalizations about "you honda guys.." for having responded relatively reasonably to such a fool hardy idea... and he's only registered with in the last three days!]

response: sounds awesome! just like any another custom swap, fab up some mounts, custom drive shafts and use the appropriate ECU. post pics when you're done.

 

OP if your hell bent on gas millage and saving the planet. Swap in an F23A4 ULEV motor & ECU. I guess that would be the Accord equivalent to the VX.

 

Yup. You could also shave some weight off the Accord. That might help MPGs

 

What the stupidity is that you have NO idea what I am trying to do and jump on me. Let me set you stright real quick. The EX's I have looked at all seem to have the V6 3.0. I am looking for something with a blown engine or on the cheap. I do not want that big an engine in my car. If I get a V6, I want it out, replaced with a better MPG engine. Going ot change it with something, so, checking my options. VX engines are the most efficiant, for whatever reason. I will start with them and work my way around the barn. Original question is will they fit, EASILY, and, what else is there in the OBDII areana?

You need to check your crystal ball because it is broken as to what other people are trying to do. Your god like guessing games are way off track. Since your broken crystal ball has been corrected in this thread, you know what I am after.

I can assure you I am not an idiot, just under educated to the Honda realm. Its only my 3rd day ever looking into a honda, I am a GM LS1 and I can surely figure out in the end what i need and dont need, I am a big boy!

 

FYI, there are V8's & V6's that are getting over 30mpg. It has a lot to do with vehicle weight and tuning. So for you to say that you don't care how much your vehicle weighs is where you need to do some more research into your gas saving engine swap.

Don't waste your time with the V6 chassis for a 4 cylinder swap. No I4 will swap in as easily as swapping one into a 4 cylinder chassis.

Just another note, your so called fuel efficient engine is only fuel efficient in the chassis that it is in now. As soon as you put it into a larger heavier chassis the mpg go out the window. that is what everyone is trying to tell you but you can't seem to grasp.

 

Ha ha ha ha, not really "hell bent" but if I am going to do a swap, trying to check all the options and pic and choose. Since the 1998 is OBDII, I have to stay compliant with that so when they hook up the smog scanner, I am cool.

Save the planet? Naaa, just want a nice ride and the most MPG I can get from it since I am going to redo the motor and tranny from the ground up. Yes, definitly needs to be an automatic!!

 

Really, is that what I asked to do? What part of easy did "you" not understand? I am looking at direct drop in's. A wise man said there are no foolish "questions", just someone that does not ask them. Point was, the only people that responded quick was the ones that thought I was foolish. Hmmm, me the troll?

 

I was about to give you kudos with your "FYI, there are V8's & V6's that are getting over 30mpg. It has a lot to do with vehicle weight and tuning. ". I should know, I have a LS1 camaro that gets 28mpg on the highway.

Then you hit me with "As soon as you put it into a larger heavier chassis the mpg go out the window. that is what everyone is trying to tell you but you can't seem to grasp"

So sad, because I grasp it 100%, you jumped on me too . I am looking at the technology of the engine. I have read threads about people just swapping the head to other engines for better mileage, so, this is telling me it is more than just size, there are some inherited engine designs better than others. Okay, yes, the weight will play a factor in there also, but, for now, I am just looking at engine A as compared to engine B.

Starting with my options, option A would be the VX engine. All wanted t oknow is how easy it would fit. Not if it is a good idea or not.

Thanks for letting me know ghost.

 

When you up the HP, you add more gas to the engine. There goes your MPG. And there is no way a header and intake will give you 30 hp. You might as well put a Type R sticker on it for an extra 10 HP.

What's this "whatever reason"? It all depends on the vehicle weight, aerodynamics, torque curve, and gearing. Why is the 3.0L V6 almost as efficient as the 2.3L I4 (18/26 vs. 20/28, according to edmunds)? What are you expecting from the VX engine, 30/40 MPG?

 

Might as well by a civic vx.

 

You don't seem to grasp it. Putting on a better flowing head in place of a worse flowing head will give you gains. But swapping a motor that's half the size/power into a big/heavy chassis, you will not have the power to keep it rolling at a constant speed. That means that you'll be cruising in 3rd gear most of the time with the motor at 5-6k rpm. And you expect to do better than 30 MPG?

 

 

Just because motor A gets 40mpg in chassis A does not mean it will get 40mpg in chassis B.

The weight and aerodynamics play more of a part than you are making them out to. You're not going to maintain 40mpg by adding headers and exhaust to a D series engine if you add 800-900lbs of weight it has to haul around.

Just buy a Civic HX or VX and be done with it.

 

i'm skeptical about you getting the mpg's out of an accord with that motor. but to help with your original questions, if you want to stay obd2, you can look at the civic HX coupe, they had both manual and auto versions, and the 96-00 coupes wiegh closer to that of an accord (civic weighing between 2300-2600 lbs, and accord weighing around 2900lbs). the motor is the d16y5.

 

Will it fit, Yes. However it's not a drop in swap. It would require custom engine mounts and a transmission adapter as well.

As I stated above, your best bet would be a 4cyl chassis and a 98-02 F23A4 ULEV engine & ECU. You could probably buy a complete ULEV Accord fairly cheap. The ULEV is a step further in the evolution of the VTEC-E D16y5. The latest and greatest are the SOHC iVTEC K24 that are based in the CR-V & Accord. These are Honda's latest evolution in the economy minded VTEC engines.

If you want easy swaps it's best to keep it in the family. V6 to V6 or I4 to I4.

 

“When you up the HP, you add more gas to the engine. There goes your MPG. And there is no way a header and intake will give you 30 hp.”

Yes, I know this, I expect this. When you have the most efficient engine compared to the engine next to it, you have to look it over. If they both produce the same amount of HP and one gets better MPG, guess which one I am looking at first. Now, I said I read where they are talking about using the VX head on another engine. That would tell me it is a better design for MPG, so, that again would make one look at that engine. Now, wether you get 30hp (from another thread somewhere in cyber space) is viable I have no idea, still reading. Does a Type R sticker REALLY give you 10hp? Don’t answer that one……

Again, true, no, not expecting 40mpg. Just trying to start is the most efficient engine and work my way up to where I have to be, with whatever engine ends up the winner.

“Might as well by a civic vx.”
I know, right!? Just don’t like the body style.

Ahh, but see, I am looking at the HP/LB ration of the CRX and applying it, as best as can, to the accord. Should give me a fair idea of what I am playing with. Maybe add 30hp or? I am working on the formula, not there yet.

---------------------------------

“ “
Easy, don’t want ot hurt yourself, lol. I would think…I say “think” the 98 accord is close to arodynamics as the CRX. Bigger yes, but shape, so close???


Double note: those LS1's get 28+ on the highway. Put them into town and they get 16mpg, so, tuned or not, in town is dredful and thats what I am aiming for.

Thanks for the info so far all, even U muffinman.

Gotta have the 1998 accord coupe body, only one I like the most, but not the purple......eeesh...

 

Just buy the Civic HX, VX or an old Insight

Buying a car with a blown motor, then to buy a motor that's underpowered and swap it in is too much time/trouble for something that is going to suck.

 

Yea, thats where the "direct drop in" question came to play. then again, if I could reuse the mounts for another, bigger 4cyl engine in the future, would be fun t play with, always looking for an "easy" car project.

 

i thought vx motor with 92hp does 51mpg not 35

he even stated that he swap out to a D16z6 which gets 35-37mpg which is right
