Im picking up a first gen CRX. For the now, I plan on either swapping in a 1994 Civic CX engine just to get it running and driveable, OR, putting on an EFI top end from a '86 fuel injected CRX. Now, should I drive it for a while and fix it up and NOT sell it, I want to do an engine swap.

Now, I know that because its a first gen CRX, its going to be some work involved.But for $200 initial investment...who am I to argue? Im thinking of either another D-series engine with more power, or a B18B or a D16 DOHC from a first gen Integra. I like the DOHC engines better. Im not looking to run VTEC(but will if its a D16/17), turbo or anything. I just want to put something in there to make a bit more power than stock because its already a very light car. That and I want to try my hand at all motor.

Also, on the subject of aftermarket parts, I know there arent going to be many. I do want to work the suspension some, but I cant find parts anywhere. Tires and wheels wont be a problem. Brakes are the only other thing I can think of.

Anyone got any advice?

 

87-89 integra motor is your best bet. You'll have to convert the car to fuel injection which is a pain though

 

Or convert the Teg motor to carbs

 

What all does that involve?

What is the engine code on those????

They are DOHC though right. Cause I was in the Junkyard 2 months ago and seen the complete engine I knew I should of got it then, cause I do want a first gen again one day. ughghgh

Its the D16A1. I have a book and according to this book it came in the CRX in Japan. I guess it makes around 113 and up hp, again according to this book.

Also, if I decide to keep it, I was toying with the idea of trying to get one of these engines to rev to 10k and beyond. Any ideas on that front?

 

1800lb car + 118hp D16A1 = pretty quick

1800lb car + 118hp D16A1 + home made turbo = own all

I hear ya, but Im not looking to turbo. Maybe later. Id like to hit 10k+ rpms first. If at all possible.

 

10,000 rpms is a big step.

first you'd have to redo the head to handle the revs. then build the bottom end to handle the stress of the revs. THEN you'd have to get some sort of MEGA RADICAL cam profile that would make power to 10,000 rpm. On an engine that normally makes power to about 6500 or so, you're asking alot.

If you're doing it because you want to build a bad *** race engine, you better have a huge stack of cash, because you'll be rebuilding the entire engine piece by piece.

If you're looking to make alot of power, turbo it.

 

Im doing this for the hell of it. Note: I didnt name a specific engine to which I wanted to hit 10k. I would obviously pick an engine with a higher redline. I know some hime 8k and above. I dont know a lot about most Honda engines, so someone inform.

 

D16A1 huh. Wasnt it the ZC that came in the JDM CRX's? I thought these two engines are fairly similar though?

I guess it would be the ZC. I reckon the book states it as a D16A1 because if you were to look for it here, thats what it would be? If its not the same, then it is very very similar. And if I dont have to pay ZC prices to get it, more power to me. Ill head on out to ****r's-U-Pull-It now.

 

God Damn!!!!(excuse my language)

I knew I shouldnt have passed that engine up when I seen it sitting in the Teg. I wouldve only cost me $120 too, who knows what was wrong with it but wouldv'e been a good start for a rebuild.

UGH I hope that No one will ever pass up a deal that you think is good initially, becuase then something like this happens and you end up kickin yourself in the *** like myself.

 

the 1g ZC engine is the same as the USDM d16a1. it has the 84-87 civic/CRX and 86-89 integra mount locations, if i'm not mistaken.

The 86-89 integra d16a1 is a direct bolt in swap for 1g CRX/3g civic, there will just be an issue with electronic ignition advance if you use an 88-89 d16a1. the 86-87 d16a1's had vacuum advance much like the MPFI 84-87 civic/crx

Why do you think Im not passing up this CRX?

Is there a way to remedy the issue with the 88-89 D16A1? I dont know that Ill be able to find many 86-87's.

 

as far as i know, use the 86-87 distributor & ECU

 

What is the issue, and why cant you use the 88-89 dist and ECU?

 

88-89 D16A1 is electronic advance timing.

technically, you could use it, but would require even more rewiring.

 

Then maybe something like this would be handy for that?

 

that will work, but the question is, do you really want to take the time to rewire like the whole car :S

 

Not really, but if its what I have to do, then so be it. I dont think Im gonna find an early teg like that here.

 

why all the talk about 1st gens, in the back of my head I know there is a 1st gen Si at my local junkyard in perfect condition. I'm guessing it doesn't run but it looks so good, I wish I could bring it home.

anyone have the pic of the black 87 mugen crx?

Well...it seems as though my luck may be changing for the better. I found another first gen for just as cheap, except this one runs. But since the running one has rust, and the nonrunning one doesnt, Im gonna do the engine swap and part the car with rust. Then maybe Ill go for the D16A1 swap.

 

i am in thr process of putting the 89 d16a1 into my 86 crx si. it is qutie a bit of work, but i think it will be worth it. i heard its easier to tune up with the electronic adavance. i also have an 87 d16a1 motor, which i am trying to sell. the 89 motor i have now, i bought the zc cams, gears, intake mani, and pistons/rods, which will add pretty good hp. you can find all of that on ebay for cheap. those parts will work on the 86-89 integra motors. also for the swap, you will need 2 integra motor mounts, axles, and hubs/spindles. im me if you need anything else.
