ok i am buying a 93 civic dx hatch and from what i know its a sohc vtec motor in it which as far as i know is a zc motor. i know its a motor swap on it but idk if it is a zc im confused never owned a honda helpppp

waaBAAH

while looking at the motor, there is a number stamped on the block. this stamping is a little below the left side of the exhaust manifold, right where the head trans and block all meet. in that general area. read those numbers and that will be the enging or block code. if it is a ZC motor it will say ZC and such.. or D16Y8 or whatever. this stamping might be dirty. the stamping is about one inch high by two inches. tell us what you find.

Should be an engine code on the front left of the block, right where the block and tranny bolt together (ex. D16Z6...D16A6) . Is the motor single or dual cam?

hondamark35

nope...

read up on the FAQ's pages. you've got a long way to go, but persistence will pay off.

the stock motor for a 93 DX should be the D15B7. A 1.5L, single cam, non-vtec with mulitpoint fuel injection.

you said you know it's swaped though, so a single cam ZC would fit that category, and so would a D16Z6 which came in the EX model for that same year. D16Z6 is definately more popular and abundantly available. the ZC not so much...

you can look at the engine block, just below the upper radiator hose, near the exhaust manifold for the engine number stamping. you may have to clean off some built up oil residue or dirt to see it. that's the motor you've got. once you know for sure, you can start searching and reading all about it!

with vtec tho? i havent got a chance to look at it yet check the stamping. guy im getting it from says he got it from a guy saying its a sohc vtec on zc block or something like that.. im gonna have to wait till tommarow or monday when i pick it up. also he has it wired up so the vtec is always engaged so i gotta get a computer or what to wire that up right idk what to do i should wait to c how he has it wired up its throwing a code bc it has a computer from a automatic and thats the only code its throwing i checked it the other day.

civicvtec44

i was there when it was swamped he blew the original out.. always good to check oil on cars u just buy...lol.. he traded a guy straight up for the motor he has in there now. the guy he got it from dont know what the hell it is so we been messing with it now he want it gone and im taking it off his hands

That sounds like a bit of a headache, and you don't seem like you know much. VTEC always being engaged is a VERY bad thing. It sounds like the guy you're buying it from has a VTEC head on a SOHC non-VTEC ZC block. To check for VTEC you just gotta look for the solenoid on the head:



It's the cylindrical thing by the head, looks kinda bronze-ish in the picture.

As for the engine BLOCK, look for the stamp as everyone said, it's by where the tranny and block bolt up together, right by the exhaust manifold (header):



Anyways, good luck, and think about what you're getting yourself into..

Hey, if you have the time, money, effort and dedication to do it right, then H-T is here to answer all your questions. Making cars your own and fixing it your own way is always a ton of fun, so I say go for it!

civicvtec44

ya it seems like this is a nice site glad to find it and hope to learn alot with this build this car is gonna be a experience.. i think it needs a new computer. ohh best part of it straight pipes to a atv muffler sounds awsome ha

civicvtec44

so what do i look for when looking up aftermarket parts

civicvtec44

picking the car up tomorrow we will find out for sure

civichb95lnd

I'd recommend working out all the bug's in this car before jumping into "aftermarket part's". Find out exactly what block, head, and ecu you have in the car and also work out the vtec wiring issue's. Your ecu should also have a barcode sticker on the side of it with number's and a couple letter's...with that we'll be able to tell you what ecu you have and if it's for auto or manual.

what the hell is a b21 am i crazy is that what i see

F20B-CX

iTrader: (1)

B21A is the JDM version of the B21A1, the engine from a 1990-1991 Honda Prelude SR. It has FRM, burns mad oil, and has very little aftermarket. It shares nearly nothing in common with the other B-series engines. In short, it pretty much sucks.

victor.m

Yes, produced for Prelude "Si States" models in Japan during 90-91, it's extremely rare.

civicvtec44

it has Zc on the block. it has a wire running from the vtec sol to some harness on the pass side..it has a rough idle very rough.

civicvtec44

im not sure about the head or ecu yet. i picked up the car last night and got it put back together and is still in a buddies barn as soon as i get plates for it im gonna bring it back to my place and work everything out

The_Honda_Guy

Looks like somebody needs to change the distributor o-ring. Just look at the oil running down the block and trans. lol

civicvtec44

green plug in first picture one wire to d6 the other? sorry honda noob here
