im doin this for a friend who doesnt have internet. a year ago he swapped motors into his EG.. the motor he swapped is stamped d15b, it has a black top, and on the back side of the head on pass side, is a block off plate with a good amount of red RTV.. right where a vtec solenoid would be.
any chance this is the jdm vtec motor with disabled vtec? maybe just a different cover? im kinda confused.. is there any other ways to tell wtf is up here visually?

any/all help is appreciated.

 

chances are, its a JDM VTEC D15B... but, the VTEC solinoid was taken off for some reason, and ran w/o it. if your buddy is romping on it, it would throw a check engine light, so im assuming he's using a non VTEC ECU?

if he wanted to, he could wire up VTEC, 1 or 2 wires, and slap a VTEC sol. on, and get a VTEC ECU, and be raising hell all over town.

 

what side of the valve cover are the spark plugs on? what is the head's cast marking? Is anything else besides D15 stamped on the block?

 

were both poor but the basic plan was prolly to pick up a VAFC (those control vtec with basic tuning right?) sry.. im a rotary guy.. all i know is rx7s right now. is there any other external features to look for? when its running i can hear a faint clicking centered around the 3rd cylinder.. ive heard vtecs click at idle, but i mean.. wouldnt that be a waste to hook up the whole thing if theres no vtec in there?! .. what if we pop off the block off plate. would there be anything visible in there that would give it away?

d15b is written with grease pen from whatever yard it came out of.. dizzy looks to be on pass side of motor

are the spark plugs on the front or back of the valve cover & what is the head cast mark? that will tell if it's VTEC or not.......

 

damn memory is fuzzy.. which one is the jdm one (spark plug entry)?
if it was USDM, it would have the vtec port cast over right? and it wouldnt be black?
it says on the cover 16valve.. thats all i can really remember right now. is it possible its just a swapped cover?

 

we need to know what side the spark plugs are on, the intake side, or the exhaust.

also, with a VAFC you really wont' get anywhere without the actuall VTEC solinoid.. so bank on getting that 1st. after that, you could make VTEC work w/o a VTEC ECU.. however, youde need tunning since your car will act like a LS.

 

yea i kno we need the solenoid. its either this or were doing the mini me swap. also.. im guessing that the nonvtec ecu isnt going to alter timing when the vtec opens right? could simply doing an all around timing advance do the job with a VAFC installed ?

 

does it say vtec on the valve cover?

if so, go out and get urself a vtec solenoid,
a p28 ecu, and some 18gauge wire.

do a search on how to wire it up, it's really easy.

you do NOT need any vafc, that would just be a waste of money.

 

the timming is minimal in VTEC..

if your really broke.. ide get the VTEC solinoid on, and if you really had to... "sand bag it"... wire a switch, handheld to 12V, and the solinoid and manually activate it.

ive done this back in the day, when i was too poor to afford a VTEC ECU.

 

haha.! were not that poor!! haha.. ill just buy the damn vtec controller..

 

the VTEC controller isn't the solution... ide rather have a VTEC ECU, and chip it!

EEPROM 0W3NS YOU!

i'm not saying it because I think you're poor.

you want that p28 man(or p08's even better, but rare), vtec controller or not.
not some hacked setup with a non-vtec ecu.

the only thing that vafc is going to be good for is tuning,
and in that case you'd need a dyno anyways.

changing the stock vtec point will do no good, maybe some harm? but no good.

but whatever, do what you want man.


P.S. vtec is not going to work withotu a vtec solenoid no matter what you do.

I guarantee you it is a non-VTEC engine.

heads with "block off plates" on the passenger side of the engine, in front of the dizzy sounds like someone either, 1... took off the VTEC sol. and kept it. 2... broke it, to cheap to replace it. or 3... dont' know what the hell their doing.

either way, i do belive the block is a VTEC engine. D15B's are like 300 bucks used.. its not like a B16 going for damn near 6 bills long block alone. D15B's are throwaways...

Yeah i have never seen a sohc vtec valve cover that says 16 valve on it.

 

the covers that just say 16 vavle wether it's the dark or metal covers it's non vtec it has to say vtec and the oil cap has to be on the top right if it's on ur bottom left it's non vtec

'92-93 SOHC VTEC valve covers didn't say "VTEC" on them. Neither do '96-00 valve covers (at least in the US). AFAIK, only '94-95 valve covers have the VTEC logo.

 

asked the owner b/c im way too lazy to go over there.. he says sparkers enter the front/exhaust side of the motor.
but the solenoid port is definitly blocked off, the dude even used red rtv to do it with a blockoff plate.

edit.. oil filler is on the left.

dude WTF kind of frankenstein valve cover do you have going on there?!!?
hahaha, vtec motors have the sparkplugs on the front, exhaust side,
and the oil filler on the RIGHT(drivers side), and they do not say 16valve on them!

there are some non-vtec's with the sparks on the front and oilfill on the right(96+)
but they dont say 16valve, they say just plain old honda on em.

hahaha, oh man, this thread is getting confusing!

just take a pic of the engine, and the engine code(plate of engine, on the front,
on the passenger side of the exhaust manifold) and post it! so we can stop all this crazy guessing about wtf is going on.

BUT, if there IS in fact a vtec solenoid blocked off,
then yes, you will definetely need to get a vtec ecu,
it will be cheaper than getting a vafc, and run the engine better than some cheaper
hack job(you said you're not that poor anyways you don't have to worry about that right?). If you can find a po8, ge that, the fuel maps are better than the p28,
but either one will work good.

 

no camera, but i have an idea of what im looking for now, and tomorro ill take a very good close look at it and send results.

just so i dont feel dumb later.. is there any other possible holes that there could be in the cover on the back pass side of the motor?

 

d15b

 

that plate is there to cover the mechanical fuel pump gear for the earlier carb'd motors. the 87 and earlier civics tht were carb'd ran off of a mechanical fuel pump driven off the cam. the sohc (non-vtec) zc are the same way. if its on the back side of the head thats what it is, if it was on the pass. side, it would be a vtec solenoid cover.
