im thinking about buying a 86' crx. but i heard 1st gens are a bitch. is it possible to put any b seris motor in it? how hard is it to get parts for??

 

Well the easy swap would be the D16a1 (DOHC 1.6L) from the 1G Integras, you can either swap the whole motor or you can just do the head swap..yes on the EW motors you can swap from a SOHC to a DOHC head....they will be very cheap and fairly asy swaps to do...

As for B series i know hasport makes a mount kit so pretty much any B series will swap in, fitment might be tight on the B18C or LS/Vtec swap since they are kind of tall, not sure if they fit well into the 1G CRXs but the B16 should swap in...

Check out redpepperracing.com they will be more helpfull with the 1G CRXs than anyone here really

 

didnt know the dohc heads swapped onto ew's...interesting

 

it's the same as any swap. buy the motor you want, buy the harness, put it in. well, basically. lol

 

What's up? My name is Julian. I did the swap to a 1987 Honda CRX, check the galleries. I'm new here. It's an expensive, time consuming swap, that is if you do not have the right info in front of you. There's really no straight forward set of instructions on how to do the swap, NEITHER IS THERE ANYONE WILLING TO TELL YOU THEIR SECRETS. Which sucks... but... I have done the swap successfully, my first Honda, ever, I've wired the car and hooked the hoses and got the car to run successfully. My only help was my knowledgable neighbor who helped with the internal work of the motor, and engine hoist.

So, you've asked and now I will help. First things first, did you know that back in 2000 Sport Compact Car did an article on the motor swap? I didn't either. That would have helped me in the beginning, but I found out after I put motor in car, and was stuck with the wiring. I have the scanned photos from the article. It was posted on http://www.redpepperracing.com, a well known site for CRX's.

 

The physical swap is not much harder than most. I believe the wiring is more complicated though. Is it more $ to do that swap than a b series into an ef?

 

Check 86si on here. He's done that swap and a lot more.

 

i believe the hardest problem with swaps and 1g crx is that they are a pain if they were not originaly not fuel injected which only si models were.

They do, but it sure as hell isnt easy, definatly not a bolt on deal.

Second the redpepperracing.com

 

xryanx6690 If you PM me your email address I will send you the jpeg scans of the Sport Compact Car Magazine Article on the swap.

You want to look for the si models, these are fuel injected models. Oh, the motor mounts are pricey: $560.

 

i wouldnt recomend a b series swap if your going to do it your self, the wiring is a mess if its and SI/HF and its a Nightmare if its the carb'd one

in the 1st gen CRX only the Si is fuel injected - DX and HF are both carb'd

on me, i though the HF was also FI...

i guess its only the ef's....

 

Hey guys I'm new here, but always read some of the posts going on. Listen I know how hard it is looking for 1st gen info. Right Now I'm in the middle of putting a B18A1 into my 86 Honda CRX SI. It hasn't been done but a couple times. I'm in the beg. stages of it but I have done lots and lots of research on these crx's. I have a web site soon to be finished providing pics, and detailed instructions on how to put the B18A into a first gen with a cable transmission. The name of my company is Exotic Creations. You can e-mail me at exotic_creations@yahoo.com or visit my web site as I add pics and info at...

http://exoticcreation.homestead.com

I'm willing to share, trade and help anyone who needs info. I'm in collage and have a couple degree's so I kinda know what up. Any questions hit me up. I look forward to what I can help people with. Or Vise Versa!

THANK YOU!
And the results are sooo not worth the amount of labor/expense it takes to pull it off.

Get a real jdm browntop ZC rated at 135ps (133hp).
The usdm D16a1 is a nice improvement over stock, but its only 113 hp.

 

The only problem with the D16 is that there is so few options to gain REAL power, and yet make it Smog legal. Try to stay away from the vaccum advance motors. And for the price of a JDM D16A1 you can buy a B Series motor, granted a little more work and money, but the tuning capibilies of a B series far exceeds that of a D16. If you want to go real low budget you can take any D16A1 head and slap it onto your Stock EW4 or D15A3 motor, put high compression pistons and WHAM O! EW4 bottom, Dual Over Cams. Or you can leave the old pistons in and boost all day!

 

ExoticCreations...hey man when you get that thing running Id love to check it out...You live about 10 miles from where im at..I dont know much about 1st gens but I work in the automotive trade so if you need anyhelp on body/paint or even mechanically help..let me know man

 

Hey what's up. I'm trying to find people around here that are into these cars I know alot of people with these cars and they always ask how to tune them. I know that these cars have almost been forgotten, I've tried lots of differant things on mine and some work, some fail. I'm a student at Clover Park Tech College. Im going for my Master Tech Degree. I also work at a local auto part store so if there is any parts or problem's you guys got hit me up. I need all the do's & dont's I can get. These cars are hit or miss!

1. 133hp (+40hp over stock) is not worth it? If by SMOG legal you mean Cali...than yes. But a 1st gen B16 is not legal either.
2. Vaccum advance? Thats all that came in the 1st gen CRX. The vaccum advance ZC or D16a1 makes swapping more realistic. There's nothing "wrong" with vac advance anyway. Switching to electronic advance is an option, but it adds a whole lot of wiring and labor the average swapper can mess up.
3. The is no JDM D16a1. While the D16a1 is similar, the browntop ZC has +20 hp on it.
No one is saying that apples to apples a D-series is better than a B-series. But by the time you factor in the difference in price of engines, the additional mount kit, ecu and vac adv to elec adv conversion... for the money, you could have a nicely modded ZC compared to a stock B16.
4. There is no "slapping" or low budget in your proposed dohc conversion. The biggest problem is that most EW and D15A engines are pretty worn out. Any serious building is going to need a rebuild or the motor is on borrowed time.
By the time you're done, you could have just as easily put a stock ZC in that cost half as much.

If you're serious about getting some help, get your *** over to redpepper and start doing some reading. The 84-87 is noticeably different than the 88-91. Whats good for one, isn't always applicable to the other.

 

If you really want to go B series I'd suggest grabbing a wrecked DA teg, you will most of what you need to do the swap...

Since my plans for my B16 CRX include stripping it all down and putting it bac together with fresh pain and new nuts and bolts where need I am planning to convert to OBD1 but not with the jumper harness, i will be grabbing a complete harness out of an OBD1 DA Integra, this will inlcued more than everything I need including wiring for pw,pl and pm and if I'm luck enough to find a GSR harness it will have vtec already wired in, or i could go with a EG EX harness but thats just and idea of how you can simplify the wiring...

Word..I went to CP Tech...I took autobody with Kurt and Greg...before that I took engine rebuild with Wayne...waaay back...Hit me up man

 

Yo davens, you must have it figured out;

1. A JDM BROWN top ZC is a D16A1, the differance is the pistons and the cam. Since you don't know, ask somebody or since you know, I'll fill in the right info .
http://technet.ff-squad.com/how-to/84-87hybrid/
D16 Head on EW4 and yes the head gasket is the same.
2. Factoring the amount of money you'll spend on getting that JDM D16A1 Brown Top you can buy a B18 motor.
3. If you find a B18A1 out of a 90-92 Acura Integra you'll find it's OBD0, the same as the EF CRX 86-87. Now if you put that new "ZC" motor on your old suspension, axels and tranny you'll probally blow everything but the motor up, so you might want to start from scratch anyways.
4. If you think you know something about redpepperracing.com you should do some research and look up KATMAN who actually designed the DOHC Hybrid model you say doesnt work. If you want i'll post the pic's on my website of the completed motor. EW4 Bottom with... Yes a D16A1 Black top head.
5. For the rest of the people in the world who have to take emissions to get there tabs to drive, a JDM motor is not US Smog legal, by the time you get it to pass emissions you can buy an entire B18A, And yes a 90-92 Acura Integra is smog legal, why do you think they have JDM motors? Those are the motor's that can't pass US emissions or are not 50 State Smog legal.
6. Being that you can buy a complete wrecked 90-92 Teg. for about $500-$1500 there really is not wiring problem as long as you can read a Helms, Chilton or Hayes manual and can spice wires.
7. Vaccum advance is crap. If you add any performace upgrade to a Brown Top, ie. turbo or supercharger there is only so far that little Vac Advance can actually advance, trust me I know. 3 motors later, you must go Electonic Advance. Because the computer can be "chipped" to handle more Advance that is the only way of retarding the spark before you run the risk of detonation. BOOM for those you don't know. And for the price you pay for that ZC JDM thing, you can make real power with Intake, exhaust and bigger cams and save a whole lot of money, and still make 30 hp on a stock EW4. But if 30hp is enough, I'll see you in my rearveiw.


Do some research before you state facts. Looks like you should take your own advice and read redpepperracing.com, remember KATMAN....
If you get away from JDM's and Import tuner mags hit me up.

1. The jdm browntop ZC and the usdm D16a1 are not the same thing. Read the link describing the differences on the same page you posted, smart ***: http://technet.ff-squad.com/ho...c.htm.

2. If you want to say a B-series swap (even a beat down, high mileage B18a) is cheaper than a D-series...whatever.

3. You're half right. The 90-92 teg is obd-0. However, 86-87 CRX is not. And you replace the tranny (and axles if you're smart) in a 84-87 ZC swap. Upgrading the suspension is good advice, but hardly relevant when talking whether to reuse the bottom end.

4. I don't need to look Katman up. I know Jason. And he didn't design the dohc conversion, nor was he the first. And since I'm wasting my breath...I didn't say the hydra doesn't work...but its more work and expense than a straight ZC, which will get you the same improvements.

5. I, and about a bajillion other people have JDM motors, and guess what? They're smog legal. It all depends on where you live...but more locations allow JDM motors than locations that don't. More people run into emissions problems rather than the fact that they're using JDM motors.

6. Buying the chassis is good idea, I won't argue. But the average HT member can't keep an extra chassis lying around their apartment/dorm/parents house.
And the wiring...a little more than I recommend for a first time swapper.

7. Vacuum advance is fine until you start getting into advanced tuning requirements. Than yes, the electronic is better, but 5x the amount of work. I still wouldn't call vac adv crap. For the record, you can change the vacuum advance curve by swapping stiffer/looser springs in the distributor.

I'm not picking on your abilities, but with a shop and experience, you're probably going to find a project easier than the average member here. So don't downplay the complexity, skill, or expense necessary for some of your recommendations.
Good luck with your "Exotic Creations".
Anybody trying to give the 1st gen some love can't be half bad.

 

Just wanted to make a correction so no one gets wrng info...

2nd Gen "DA" Integra is 90-93
90-91 Teg is OBD0
92-93 Teg is OBD1

 

good catch.
