Just as the topic says i am looking to decide what motor i should swap into my 86' Civic CRX Si... Any suggestions?

 

B18C5

If you've got money to burn than hell yeah go for the c5. but if your money concious do a ZC, it adds quite a bit more HP that your stock motor and is dirt cheap and easy as hell to put in.

Just as an example, my friend just put a D16A1 into his 86 Si. Then he put a junkyard turbo kit on it. It's actually done very well, it's just all stock parts. He's running like 6-7 psi and that thing screams. He WASTED my friend that has a 96 coupe with an H22 (I/H/E).

Just my .02

 

i wish i had a two thou to start an 86 crx project...i'd go with d16a6 motor too, but i'd go all motor. exospeed head and 88-89 teggy pistons...nothing too wild, but i'm sure it'd pull pretty well in an older crx

 

just get a mount kit for b series, then get the motor fitting in your budget, enough time on honda tech and you should be doing your own swap in no time.

 

i just bought an 87 DX. I just swapped in the Si block and put the DX head back on for know. The Si head will be shaved a little to icrease compression and i'll do a little port job on it to. Then go on the Mikuni's and the Jackson racing header. Wish it was an Si to start with so i could went FI, but it's fun to learn something new, i don't know a damn thing about carburetors. Here's to tuning fun

 

no fun trying to tune that carb. I'd convert to FI

 

b16

I agree with the noob

 

B18C5 and this car will dominate

one letter and 2 numbers for ya H22

 

you'll never get a H22 in a 1st gen REX however, A B anything is going to be a tight fit. Now if I am wrong I would really love to see a picture to prove me wrong. In a street driven car of course.

there was a guy on here a couple months ago that sqeezed a accord v6 motor in there so why wouldnt you be able to get an h22 up in there?

 

remember this is an '86 rex not a 4g, that engine bay is even shorter than ours, and its next to impossible to do the H22 in ours, Oh it can be done, just barely, in his there isn't as much room.

 

yes it would be a bitch yes you would have to have alot of custom work but Im sure you could do it
but what you are failing to realize is that there is just as much room inside the bay just not as much as you can see just by looking in there. I would be willing to bet if someone had the cash time and effort to try this it would work and still be streetable

 

im actually not a noob, a mod got pissed because a friend of mine whooped the crap out of the mods car. .

 

my understanding of the 1st gen rex's is there are a few inches less forward of the firewall than a 4G has. B swaps I have seen look like the car was built arounf the engine not the other way around. besides, with a H22 you are going to have a seriously nose heavy car, the B series has 100lbs on the D series and the H22 is even more.

 

whatever im tired of arguing with you im finished with this ****

so you win have a nice day

 

Not trying to argue, just want this guy to know it may not fit before he blows his money and finds out it won't. And from what I know about 1st gen REX's I am sure it won't. Would you like someone to tell you oh yes this will work , run out and buy the stuff and find out it won't?

 

I myself know to do a little more research before I start a project I mean before I swapped my crx i read for like 2 months on the swap and things of that nature.I am not trying to tell the guy to go out and buy an h22 and just bolt it in because you and me both know thats not what i was saying What i was saying is that if you had the money time and resources to do some custom work it would be a killer swap to do in that little light car now as much as you would like to say that it wont fit you are wrong because just a couple years ago if you remember it was impossible to swap a h22 into a 2nd gen crx or just last year everyone was saying it was not possible to do a kseries in an eg or ek or even an ef but now there are daily driven cars with this swap so don't sit there and tell me it wont fit are it cant be done cause that is bull every thing that has been said is impossible someone stepped up and done it so just leave it alone and let him decide on the facts that are given.

and before you ask yes I never went to English class in high school

 

I'm not the grammar police. So you won't catch hell from me about it. But I do detect major attitude.

This guy clearly doesn't have bottomless pockets so a custom NSX swap into the back of a Rex while clearly possible for someone with enough money is not an option to this guy. If he has to ask it means he does not have those sorts of resources availible to him. He wants a practical swap. that would be either a ZC or a B series swap. Mounts are availible for those. If he had unlimited resources unlimited access to a machine shope and the requisite machine shop and fabrication skills he would not have asked the questions he did. Sure he could put a small block Chevy in it IF he did a full tube frame and converted to rear wheel drive, but then thats way outside the scope and abilities of most people now isn't it. Congradulations about thourough research before embarking on a swap, not everyone does that however. I would not be the guy to talk a guy into buying a swap that costs that much abd find out it will cost $4,000 in custom fabrication to make it work, and then have a car thats so nose heavy its dangerouse to drive on the street. A 1g Rex is a LOT lighter than 88-91 civic or Rex. that extra 300 lbs(more or less) in the front makes a big difference.

 

1. you wont have to have a full tube chassis to put an h22 in there
2.yes it will be a little on the nose heavy side
3.yes it will include allot of custom fab work
4.yes it will be expensive
5.no he doesn't need to attempt a swap of this magnitude i was just trying to state that it can and probably someday will be done
6. we are way off topic so im going back to my original post a b16a would be a great swap for that car.

and last but not least im sorry if i was an *** to you i just seem that way when i am trying to prove a point

anyways put a b16 or a sohc vtec in there and call it a day...

 

No problem here, just so he knows the H22 is not the best option for a backyard mechanic.

Do you have proof of this?

I guarantee my b16 does not weigh 100 lbs more than my old d series.

 

Do a search, subject has been discussed and each engine has been weighted. The B series is heavier. Have seen multiple quotes about this last few years. The B series is physically larger too. The D16 is lighter and makes more bottom end torque but can't rev like the B due to the long stroke it has. The B series has some advantages but at a weight pealty, same as the H22 and the K series. they are even heavier.
