ok starting off my spelling is bad yes i know this do i care no so dont tell me what i alretty know if you dont know what word im trying to say just sound it out because likely thats how i typed it how it sounds

and i have a few q?'s

ok i ricently bought a 86 honda crx si right now it has the norm stack sohc and i would like to up grade up a dohc and a friend sugested the d16 and told me that all ill have to do is cange a motor mount or 2 wich to me sounds like a lot of work ( not realy done this before) is it like my friend says its just pulling a bolt placing a hole and pulg and go or is ther more too it and is there a dohc vtec that uses the same moter mounts and works with the trany thats in there

now im sure ill make someone mad with this coment but belive me its just me not knowing to much about them just yet still need to read up and learn more about the crx

ok what is the defrince in body on the 86 to the 88 looking at them online dosent help they look alike to me and was wondering if it was just a defrent motor or trany that makes them defrent because im looking to make some body mods to this car as well and all the body mods i can find are for the 88 and i cant see why they wont work for the 86 as well so plz help me settle this are the bodys the same and can be changed out between the 2 or is there some crazy defrince to them that wouldnt let me make body mods to the car

 

You're not posting in the best place for info on these cars...

this site is amazing: http://redpepperracing.com

Here's their FAQ on motor swaps for this chassis:

http://www.redpepperracing.com/wiki/...y:Engine_Swaps


Good luck! I want one of these to build a racecar out of..

 

well sorry thought this sight would be able to anser my q? Only thought that because of the post about the d motor line post and seen that this is an 1988 crx area some one might be able to tell me the defrince between the 86 and 88 for all I know they changed the gage cluster and motor size. If the body didn't change then that's all I really need to know so if I decide I need new headlights I won't be limited to the 86 I can go out to the 88 and get some off that year of car

I know the start of this seem roude but its not ment to be

 

mainly the body style, i think the 84-87 si motors are ew codes instead of d series and also i believe there 12 valve, but yes major body differences the 86 model has squarer headlights than the 88-91, fenders, hood, doors this is all different from the 88-91

 

Will the the bodys fit each other or is there to much of a defrince

 

no worries, i don't post here often and i'm not trying to chase you away! people here know a lot about the D-series motor, and probably a good amount about the 3G civic and CRX.

I'm just suggesting that if you have that generation of crx, the redpepper site is full of motor swap info, specifically for that car. They focus on just that chassis, so you'll probably get the best information there.

Honda-tech has a 'classic hondas' forum here that might help you out as well:
https://honda-tech.com/forums/classic-hondas-106/

From what I know and have seen, any d-series motor is a fairly easy swap into these cars. BUT you really want to speak with someone who has. Even with an 'easy' swap, you'll want to research it and check several writeups before you do it, if you haven't done that kind of work before.

Good luck with the car! I love that chassis.

 

I believe the chassis are completely different, there are very few if any body parts you can bolt straight across. The suspension design between the 86 and 88 is also very different.

I'd say you are far better off to stick with parts from the same generation, that is, 86-88. The 84-85 headlights are different from 86-88, as you probably know. I did have an '87 CRX once!

I've never tried it, but I don't think you could just install the 88 headlights on the 86 at all, not without swapping the whole front end, which seems like an insane amount of work.

You can't even get good fitment between the '88 JDM and '88 USDM headlights without changing the body panels and bumpers as well, as far as I know.

The 88-91 D16A6 motor, however, can be swapped. As can the DOHC ZC, which was found in JDM Civics (and, I believe, USDM Integras around that time).
Here's the wikipedia section on the ZC. It's a very popular swap for your car.

I can't recommend the redpepper site enough!

 

ok now will the trany from the 86 mach up with the d16 motor?

 

nvm just read its a L3 Gearbox - Cable Tranny and the crx is a L3 on the si modle now the q? is can you make a d16a1 vtec motor fit the L3 tranny because the sight im looking at says the vtec d16a is a y3 or do i have to replace the trany too?

heres the sights im looking at

http://www.crxsi.com/specs.htm

and

http://en.wikipedia.org/wiki/Honda_D_engine

 

I bet you do have to, in fact you'd probably want to would you not??

I guess i have to actually show you the forums over at redpepper:

And, here is their forum DEDICATED TO MOTOR SWAPS for the 84-87 chassis:

good luck! it doesn't look that bad, motor swaps are fun!

 

ok im so ive found out that the bodys arent the same and to get a dohc vtec i will have to chang out motor mounts and gest a new trany now reading back there was talk about the chasse now i did a quick surch and came up with this

that the 1g chasse is a AF Chassy im not sure this is right so here i am back agen asking what kind of chassy doses my 86 have so i can try and look up some info on it i read the redpepper sight with the links on it wich didnt exactly anser my q?'s

 

they are totally different generations of CRX. so completely different. first generation CRX's are 84-87, second generation was 88-91.

 

just curious as to why nobody has directed the op to the proper forum listed below...!!!
https://honda-tech.com/forums/forumdisplay.php?f=106

 

the motor mounts are in a different place....the dohc zc that fits into that chassis is the one from the 1st gen integra (d16a1)....another difference is the body style...its more boxy looking than the 2nd gen crx...plus the 1st gen crx has plastic fenders while the 2nd had metal ones

 

92-95>88-91>84-87
Yea the difference was the 84-87 were made of cheap plastic and the 88-91 where solid.

 

Hi OP! It's good that you spent some time checking out redpepper. Much of the information you see on 'classic' Hondas here on h-t seems to be pulled from that site. You'll remember that I did include a link to the 'classic' section on h-t above, though it's better to go right to the source.

The best and fastest way to know for certain which chassis code you have is to go check your VIN. It's good to be able to read your own VIN. Your chassis code is part of your VIN.. the way Honda used the VIN changes over the years, here's a good guide:
http://en.wikibooks.org/wiki/Vehicle...onda/VIN_Codes

To reiterate, your CRX is VERY different than the 1988-91 CRX. I love the 3G Civic / 1G CRX. It's a small, light chassis! You've started in the best place possible by having the Si, it seems (it's already fuel injected). Congrats, you've already saved yourself lots of time. I do love dual-weber carbs on those Hondas, but that's another story!

If this is your first swap, you might not want to bite off the DOHC VTEC (B-series) swap, though I'd still research it to see if it is something you might want to tackle. Documentation on K-series swaps for your chassis is a bit thin and I doubt you are looking at doing that. But it's been done before!

It really looks like the simplest, bang-for-the-buck swap for you is going to be the 'ZC' swap, though don't let me tell you which swap is best for you! I'd also check out later-model D-series swaps, since any D-series motor will be physically similar to the ZC. With later-model D-series motors, the OBD-0 --> OBDI and VTEC wiring will be the harder stages of work (but the payoff is that you get VTEC).

For simplicity, and your first swap, it's easiest to stick with one of the other motors Honda manufactured at the same time.

Here's a good backgrounder on the different engines available during your generation:
http://technet.ff-squad.com/how-to/8...id/1.6dohc.htm

For the ZC, you'll really be looking at taking the best parts of a same-generation (86-89) Integra and stuffing them in your car.

Here's at least the beginning of an old 'howto' swap article on the ZC and D16A1:
http://technet.ff-squad.com/how-to/84-87hybrid/

He didn't discuss wiring there, but it looks like you use the Integra harness, just like I did on my B18A1 swap into my ED7. It looks like a very similar swap, just for the previous generation.

Here's the thread on redpepper in which I found the above article:
http://www.redpepperracing.com/forum...pic=13257&st=0

If you follow various links and do more research from there, you should find all the information you need.

I researched for weeks, maybe a couple of months, before jumping into my first and only swap. That's all I can recommend -- find two or three different sources that say the same thing, and you can begin to feel confident in the information you've found.

At the end though, all the work is most definitely worth it!

I wish I could help you more, but I'm not an expert at all, just a fan of the 3G Civics.

 

.. and really, if you haven't done so already, I'd set up an account on redpepper, and continue researching and asking questions on there. I have no idea how friendly they are, but that's where the best knowledge on your chassis seems to be.

Good luck!

 

got another q? for yall i need to replce my pisten rings in the motor i have in it now i wich is the sohc ew3 and im not sure what size they are i did a little looking but coulnd find anything on my fast serch so before i spend more time i stoped here realy fast so if you happen to know wich one out of the 2-1.50mm 1-4.00mm 2-1.20mm or the 1-2.80mm i read some where that depending on what i want it to do depends on what size right now till i can finesh up my surching and saveing its just going to be a driver so fuel effichent would be my best gess
