Finally gonna do it. I'd say the most advanced thing I've dont to my car so far is replacing an axle or installing shocks/coilovers. I did do a swap with a friend in his 89 hatch.. tho the car still doesnt run. Hopefully dropping the ZC in wont be too hard. I've got a couple lil questions.

Im gonna be using my Si tranny.. will I just have to take the Si tranny off the Si block then take the Si pressure plate and Si clutch off the Si block and put the Si pressure plate and Si clutch on the ZC flywheel (ZC flywheel will come already on the ZC right?). Will I need an alignment tool to get this done? Where can I get one from?

Is it a MUST that I port match the Si exhaust manifold to the ZC block? I want to do it but I dunno how I'd do it.. would a dremel work? Also, will I have to port match a DC header when I get one?

What kind of people ship engines.. its not Fedex or UPS is it? How am I sposed to get it off the truck or does the truck driver do it? Alot of my questions are questions that I just dont know because I've never gone through the whole experience before.

What kind of coolant should I be using in the ZC?

All the bolts on my car are insanely tight... which ones do you think I'll have the biggest problems with? (I know the exhaust is gonna be a real bitch).

Im gonna call Steve at hmotorsonline tomorrow after school.. think there should be anything I should try to request? Im already gonna see if he can get me a 91 motor instead of a 88-90 just so I'll know its the newest... any other tips?

Thanks in advance for all the help. I had to work for a while to get this money.. I dont wanna waste it by doing something wrong.


Heres of a pic of what the ZC is gonna be going into..

are you going from SI to ZC?
id say keep your SI and put a cam and bolt ons in it , it will whoop the ZC


[Modified by Timmay, 11:27 PM 3/4/2003]

 

thanks for not reading the post.. yes Im going from Si to ZC.

 

dude keep the SI, mill the head, get a nice cam and some bolt ons, it will tear a zc up and be about the same price if not cheaper

 

grrr, I wish I could get some help. I didnt ask for someone to give me suggestions on setups but I've already made up my mind on the ZC. Im not tryin to be rude since I DO want help.. but that just annoyed me.

If I really wanted to, I could do all that to the ZC and be even quicker.. Im looking for a better platform.. the engine wont stay stock.

cool have fun with your ZC , i hated mine, pretty sad when my stock 91 DX with MPFI swap would damn near beat ZC powered CRX's

 

Thanks, and yea I agree thats pretty sad. Next time you might wanna try learning how to drive that ZC.

 

clean crx.

i just orderd a dohc zc from hmotorsonline. you can use your Si pp and clutch. you can use the zc flywheel and it will just bolt up to ur Si stuff.

portmatch w/ a dremel? NO. the motor will came with the exaust mani so it just bolts right up.

coolant. het the autozone stuff. coolant is coolant.

the exhaust is the hardest one.

 

I know it comes with its own exhaust mani but its a 4-2-1 style mani and the stock Si one is 4-1... so you're saying I'll get both peices of the ZC 4-2-1? some people dont.. that'd be a releif, I'll probably have to ask Steve that one.

How much did you pay for yours and how much was ur shipping? IM me if u dont wanna publisize it.

 

Oh yea, and will I have to get the ZC flywheel resurfaced before I put the Si stuff on? thanks for your help man.

 

its better to get it resurfaced.

:edit: 645 shipped to my friends door.

The flywheel should come on there, its always good to get it resurfaced while the engine is out, makes the job alot easier. For the alignment tool, try like pep boys or autozone. I'm sure they don't cost to much.
Not a must, but I'm sure if the si ports are smaller then the zc ports you will loose alittle bit of horsepower.
It will be a local company more then likely, the truck will have a lift on the back and the driver should have a pallet mover in the back of the truck

Just buy some from autozone and mix it with water, 50/50 .

The axle nut and the crank pully bolt, and you might run into some problems with the roll pin.

I don't know of any tips, just tell Steve what you are doing and he will take care of you from there.

damn, thanks for all the info, you answered all of my questions.. but why will I have to take off the crank pully?

Oh n/m, you're talking about when I replace the ZC timing belt arent you.. right?


[Modified by drjondurst, 12:57 AM 3/5/2003]

 

If your Zc flywheel isnt resurfaced when you get it, make shure you get it resurfaced, it s only like 30 bucks, ive seen people who didnt get there flywheels resurface and it messed up there clutches.

 

Do you think since I havnt ordered the engine yet, I can ask steve to do it before he ships out the engine?

 

If you not changing the timing belt then you don't have to. Sometimes the exhaust manifold comes cut in half. And about Steve doing the flywheel, I'm pretty sure he won't. He is a busy man with alot of orders to complet.

ok, dr. I just got my motor (complete swap) b16 from them, and i'm pretty sure if you order the zc you get both pieces of the exhaust manifold, and i'd use that instead of the si one, the si one was used on a 108 hp motor and the zc is used on a 130 so it would make sense to use the zc. Also about getting the motor delievered, do you have abuddy that owns a shop?? or know anybody who would let you deliever it to there shop, cause that will be the easiest way, also if you don't want to pay 65 bucks so the truck will have a lift gate, you better make sure the shope has either a forklift or a engine hoist. If you don't want to go this route you could just give hmotorsonline any shops address, and when he gives you the tracking number you can clal the company, **** i forgot the name but he deals with the same people everytime and they are real cool, you can then ask them where the nearest docking station is, and they will tell you and thne you can go pick the motor up at the docking station, they will have a forklift so bring your pickup and they will probably help you get the engine in your truck, it was no biggie for us. I wsa gonna ship it to a local shop but found out it would cost more money to get it off the truck so i called the company and asked them to send it to closest shipping station and it was all good. I know you have already made up your mind but if i were you i'd also get the zc tranny and put the si final drive in it, this would make for a faster car, and if you are worried about high rpm's in fifth you could get the hf fifth gear, shipping cost me 250 bucks (commercial zone) but that was all the way to kentucky, If you've got anymore questions my aim name is one of these two:
phathardy
honda crx 90 si

or pm me, peace out, hope i was help.

 

read it better, my DX was almost beating crx's with ZC's

anyway i would change your timing belt before you put the motor in, ive had people get ZC's and the belt snapped in under 100's miles, better safe then sorry

most likely you can use the ZC upper half of the header and SI for the bottom.
the ZC flywheel and clutch will work fine, if you want to change to si you dont need to resurface if its the same clutch that came off the flywheel. if its a differnt clutch then yes for sure resurface

oh and you better start stocking up on distributors casue it will go out on you, 90% of ZC's have this problem


[Modified by Timmay, 12:11 AM 3/5/2003]

 

Talk to Steve about the exhaust manifold, ask him if it will come with the hole thing or if it will be cut. Tell him you want the full exhuast manifold.

 

Thanks for all the info guys.. phathardy.. I imed you.

Timmay, I thought you were saying that your ZC was slower than your DX..? Thanks for the info though. If I wanted to go through the trouble, would I be able to just swap over the Si flywheel onto the ZC? I'll most likely go ahead and get teh ZC resurfaced but Im just curious.

90blackcrx, Im gonna talk to Steve and see what happens. I got the exhaust porting idea from here: http://thenew.gamesbbs.com/~dmoore/zc-phase3.htm Check out the part where it talks about the manifolds.

 

damn 1am snuck up on me.. Im gonna get to bed, I"ll check this in the morning.

 

Don't listen to this guy, i believe the DOHC ZC is one of the best motors for the money. I live in Mich, so i just go up to Canada to get mine, i spent $400 U.S. on it. Best $400 i've ever spent. And having an Si your starting from a better point, you don't have to change your hubs or add as many wires to your ecu, i'm not sure what size your spindles are but you may actually get to reuse your axles. If not get 2 right 90-91 teg axles if you have the intermediate shaft. You'll also have to run wires for the cam position sensor. If you need help with it e-mail me i'll tell ya what u need to know. Other than that do what those other guys said, resurface the flywheel, definately change the timing belt while it's out, and inspect all of your hoses carefully before u install it. This is just a little extra if you have some extra cash, if you take the final drive out of the ZC tranny and install it in the Si tranny you'll end up with a better gear ratio. If not sell the ZC tranny on ebay, i got $200 for mine. Hope your swap goes smooth

 

yea dont listen to me dude ive only installed and raced plenty of CRX's and civics with ZC's and 9 out of 10 the SI motor comes out on top. a SI motor with I/H/E cam and milled head will beat a ZC with I/H/E. i like the d16's casue there are more parts avail., ZC's are always having problems and they are a dime a dozen

your SI axles work just fine, the stock ZC clutch and flywheel should work just fine

 

wow , ur a testy fella aren't ya. I'm not denying your " vast " racing knowledge, but i've driven with both motors and i prefer the ZC. And the part about parts being hard to find for the ZC, almost all D-series parts fit on them, so it's really not that big of a problem. Now go to the fridge, grab a beer and settle down.

 

oh its all good dude, i just dont like ZC's they arent all that people think they are. im just saying that IMO the d16a6 is a way better motor and is a better platform that the ZC
i wish i had some beer or even pop, god im thirsty
