vtec for non vtec. need help

I got a 92 civic vx hatch that I wanna put a d15b7 vtec in. I got no money for a new ecu. Can u run the vtec with the old ecu? and just not use the vtec? please help. I got the motor for free and its got only 20k miles.

The d15b7 motor is a non-vtec motor, it's from a DX or LX. The d16z6 is the '92-'95 vtec motor. And if you got that yes you would have to have the ECU (some people hook it up to an RPM switch or something to get it to work). And you would need to run vtec for the motor to run correctly, again if you have the d16z6.

The engine I got says vtaec on the valve cover , could someone have put a vtec head on an old block or something?

Yeah the previous owner could have put the d16z6 (vtec motor) head onto the block. Personally I wouldn't trust a motor that had a head swap like that, unless I knew the person who did it; but that's just me. You never know what the person did.

Check the engine stamp. If it says D15B(no number at the end) it's probably the JDM D15 which is VTEC, if not it might be a mini-me.

There is a possibility that they had just switched valve covers too, but I don't know if a VTEC head's valve cover is any different than a non-VTEC head's valve cover.

The heads on the non-vtec vs vtec are different I believe. I believe the plugs are on the other side on the vtec engine.

Yeah the spark plugs as well as the oil filler cap are on the opposite side of the non-vtec ones. Vtec, the plugs are in the front, non-vtec they are in the back.

D15b1 isn't a VTEC.

:sly: No one even mentioned that motor. And of course it's not, because it's an '88-'91 motor and vtec didn't come out for the D's until '92.

That's what I meant, I was just too lazy to scroll up to the top and see what the #s were after D15.

The engine stamp is d15b with no number but then under that it says -7

Then it could be the jdm d15b vtec engine. Check to see where the spark plugs and oil cap are on the motor to know for sure.

I've been having a truck fetish lately then my roommate rented Need for speed underground 1 and 2 and now I'm leaning back towards the cars again. Probably won't be a honda, but who knows...

and how have you been?

I took a bit of a hiatus too. Came back and on the second day almost got banned lol. So it's been pretty good.

Hope your girl came out of that accident safe.

Yeah, you don't wanna get yourself banned, that kinda sucks lol. Not that I'd know or anything. :D


and yeah, she's fine. Had a headache for a couple days, but she's fine. :)
