i have recently bought a crx that has a zc motor swap and the only thing i on the block stamp says is zc how do i find out which zc motor this is i need to replace my timing belt BAD and need to no what to order it for but having no luck finding out even what the motor came out of if anyone could help i would apprciate it thanks slick

digitally_remastered

well, lets start with this. is it a sohc or a dohc zc? if its a sohc, does it have vtec or not? lets get this established first.

zcmustangslayer

dohc

digitally_remastered

ok you may want to check out thezcr.com

they have a parts list there for you to get all the items you need to rebuild your engine. its where i found all my info long before i even thought about getting a dohc zc, which to this day, i may be getting on saturday lol.

zcmustangslayer

what kinda car do u think that came out of

digitally_remastered

well it came out of a JDM 88-91 civic/crx. but there are different versions of the engine that came in later years as well. knowing which one you have is the biggest mystery of all. i do know that for a timing belt you need an 88 prelude 2.0 si belt.

heres a link to a downloadabel pdf file for the parts list.

thats what i have been told and thats what im going to try so how do u feel about the zc motor good or bad

zcmustangslayer

its a hm5 stamp either on the head or the block cannot rember which

DCRB

zc's are great. they're the top d series stock for stock IMO

jlicrx

if the engine serial number just below 'ZC' stamp on the block starts with the number '2', it is from the 88-91 JDM CRX Si or Civic Si - HM5 is the head designation

i just got my 91 crx and im having trouble finding the engine code. im pretty sure its the d15, its an auto, any ideas?

zcmustangslayer

so this is a 1.6 liter right

digitally_remastered

yes that is correct.

just-inMYcrx

i was thinkin it was the 1.5L because of the difference in the air intake. how can i know for sure?

just-inMYcrx

i eventually want to convert it to a 5spd but that will be a while since i have nowhere near enough experience. what performance upgrades would anybody recommend for starters other than a cool air intake?

ef8sleeper

for this zc engine all you have to do is go to the parts store and look up parts for an 88 acura integra with a 1.6.
this will give you all the right parts for your dohc zc.

where is the engine code located on my 91 crx auto? i never really got an answer

zcmustangslayer

the code is on the right side near the tranny about half way down on the block

zcmustangslayer

so i have if sould i get the timing belt for a acura or the prelude and what if i need the comp. kit or tensioner?

jlicrx

timing belt tensioner and water pump are 88-91 CRX/Civic Si D16A6 - timing belt is 88 Prelude 2.0 Si

jlicrx

not true - for the OBD0 DOHC ZC, most all of the parts below the top of the block, except pistons, are the same as 88-91 CRX/Civic Si D16A6 - parts above the top of the block are the same as 88-89 Integra D16A1 - timing belt is same as 88 Prelude 2.0 Si - some parts are the same for both D16A6 and D16A1 - some parts, like bare cylinder block, bare cylinder head, valve cover, timing belt covers and timing belt gear on the crankshaft are unique to the DOHC ZC

ok thanks. does it mean i have a blown gasket if my spark plugs are practically bathing in oil? or could it just be from the bad tranny?

zcmustangslayer

there is a good possibilty it could be the tranny but i would get a vavle cover gasket set first

just-inMYcrx

well i know i need a new tranny cuz it wont shift past second. but i know that oil shouldnt be on the spark plugs but i wasnt sure of what it could be. how many gaskets come in the set?

zcmustangslayer

it is one gasket but it has orings in it that go on the spark plug tubes to keep oil out
