im thinking about keeping my stock d 15 and building it. after getting it in working order,i would like to change it to multi point injection and add a turbo. i figure i can spend about 1200 dollars and not be out more than if i would have swapped it . and it seems to me it would alot easier to do this than a swap myself and im not trying to make monster hp,id be tickled witha 13 second car.some questions i have are,do i have to get a new head to change it to multi point?,can i get a performance camshaft for a d 15,and would i need new pistons/rods. tell me what you think,even if you think im an idiot because i dont care,any help would be appreciated.this is my first honda,fisher- price my first crx,and im just trying to have fun.

1. In order to have a 13 second car, you need in my estimate about 180-200 HP. You have obviously not ridden in a 13 second car to know just how much power that requires. I've been in an 11 second car and I find that there's cheaper ways to make a car that fast, and its usually not done in a Honda. My 130 HP DOHC ZC Civic SI would run about 15.7. Honda, fast and reliable are rarely found in the same sentence.

2. You can use the same head, you need a different intake manifold and throttle body and a multi-point ECU for the MPFI swap. After that you run just two wires from the two new injectors up through the wiring and back to the ECU.

3. I am not sure about the camshafts

4. In order to get that much horsepower to do what you ask, you need alot of boost. I do have a friend who did a DOHC ZC swap and with boost runs an estimated 14 sec quarter. It is attainable, but he may be having a few reliability issues here shortly.

 

thanks for the informatin and ive been in a 12 second car beafore a fox body mustang.and you are right honda, fast, and reliable dont mix well togother. i didnt mean to sound like i expected a 13 second car id be happy with 15s because this is just something i want to mess around with and figgured i could get some good info for it and get a couple of projects going.it is a cool little project and was cheap as hell so thats the way i want to kep it. the thing is just working on cars calmes me down so why not get a project started .i want a mustang or a dsm but thats not going to happen because i dont have the money or the skills to keep it going with crazy hp so i will run with this.all my friends have mustangs that haul *** and i wanted one but got tired of searching and having nothing to call my own. now i do it might be a pice of **** but its mine you know what i mean.

 

Maybe you should spend some cash to new motor. I dont think the D15 got what you need.

The Dohc ZC would be affordable, and you can squeeze nice powers from it too. Build a turbo to it, and it can be fast.

B16A Dohc VTEC, i think that would be better option. Of course, with 20hp more, and its a B- series. Witch gives you benefit of tuning possibilities. You could run a turbo here aswell, and you will get respectley results.

You just need some cash, skills and knowledge.

Good luck for your project.

 

yeah but whatever you do dont get rid of that 6 speed transmission.

 

i dont want to. thats one of the reasons i dont want to swap it out.also i dont think that i have enough skills to do a motor swap myself, and i definatly dont have the tools.i cant have it done by a "mechanic" because i dont have enough money for that and i dont think i would trust one,(if i make a mistake on something,at least i know what i did wrong and its much easier to fix). after thinking about this today i have some more questions,if i were to do a swap, i think i would do a dohc zc,but would that bolt up to the tranny i have now?,i really want to keep the six speed,does the zc just bolt in or do i need a mount kit?,if i were to keep the d15 like i said i wanted to and change it to mpfi what parts would i need? would i need to change the wiring harness for the car or just the motor?, and would i need any fuses -relays that type of stuff? im trying to get detailed parts list going because the junk yard im going to dosent let you pull your own parts.and id like to get as many as i could at one time. its cool if you cant answer all of these questions, but i really would appreciate any help. also i dont really want to mess with vtec i dont think i have the skills for all the electronics and wiring. like i said this is my first honda and im kind of running in the dark.

I think I missed something about the 6-speed tranny? if it bolts to your d15b2 block, then it will also bolt to other d-series engines, a zc would be the better choice, as it has fair power, is dohc and pretty simple in terms of wiring. you will need to do a mpfi wiring conversion which is a pain in the butt if you don't know what you are doing. another choice is the D16a6 engine (about 108hp) that will bolt up the same as the zc, but probably cheaper and easier to get than the jdm zc. either way, you will have to do the mpfi conversion to help get better power and use a better ecu. the d15b2 just doesn't have the potential you are looking for at all. i used to have that engine, and I installed a camshaft out of a d16a6 and ran open header and cold air intake at the track (street tires, 32psi) and my best run was only 17.3 seconds. definately look into something better than the stock engine, as the only thing good about it is fuel economy. good luck!

ps. about tools... if you are serious about doing this stuff with cars, start collecting tools by getting lets say, a pretty decent socket set... I would highly advise craftsman stuff so you can get free replacements if you break anything... lifetime guarantee and just start getting hand tools like that as you go.

 

^^I agree with that statement^.....But getting into the 15s with any D-series engine is hard on the pockets......I dont think your car could hit 15s if it were falling off a cliff.....Invest your money and time wisely, surf the web, read and absorb all the info you can, research and last but not least TAKE YOUR TIME
Hell we live in the same city Id be more than glad to help you out...Good Luck to you

If you live in the same city, why dont you go and see the 6spd D- series transmission. I would like to see that too.

 

i think i will go with the dohc zc swap. i just need to get up on some money,im not trying to spend my last dime on my car not yet atleast,i have all the hand tools i just need **** like a cherry picker and sodering iorn. i just will take my time on it.and once i start doing it i would definately appreciate some help man. so thats cool that you live in vegas its easier to have some some face to face help some times. also will the tranny on the d15 really bolt up to a zc?i gotta get a project list going and gotta get some synchromesh because i have a second to third grind so hopefully that will take care of that. hopefully.its gonna take a minitue to get all this in order bute like the dude said im just gonna take my time.i think im gonna get started on the body work now.does any body know how to take the rear passenger quarter pannels off, it looks like a bitch and the haynes manual dosent show how to do it?also what year and model does the zc come in because some of these engine sale web sites need tat instead of just putting up a list? thanks.

That's not true, it all depends on the car. But if you are talking about a crx or a hatch, 160hp with a good driver and tire setup and if your suspension is still good, you can break into the 13's

 

i think i could get a hundred sixty hp out of a zc especaly with a turbo. im not really setting up for a 12 second car more like 14s i would be happy. i figure that would be decent with a cheaper motor and set up. i was looking around at prices at first i was looking at osaka because its like 600 bucks, but i read alot of bad **** about that company. noyan wants a thousand so i dont know about that now. how much does hmo want, they want to call you with the price so i didnt fill out the form.if anybody knows that would be cool.
