I Need Help With Vtec-e

[dougshatch]

What range Horsepower D15B Vtec-E? Some people sed its 125-130hp other people sed 95hp so i dnt know which 1 is right hp for it

[CivicSpoon]

Are you talking about the JDM 3-Stage vtec engine? Or are you talking about the USDM '92-'95 VX engine? You sure you mean D15B?

Edit: I looked on Honda's Japanese website and I found out the 3-stage vtec engine has 130ps (roughly 128hp).
The USDM D15Z1 ('92-'95 VX engine) has 92hp.

I'm pretty sure you mean the D15b that came out of jdm 92-95 civics. Its obd-1 and according to hmotorsonline has 130 hp.

It's the 3-stage vtec D15B, and yes it has 128hp (130ps). It's different than the '92-'95 D15B vtec (the one closest to our usdm d16z6), but it does share the same hp rating.

But honestly, it's not really worth it for the economy part, especially in a 4th gen civic or crx. It will be a wiring nightmare; converting from OBD0 to OBD2, and then finding a wiring diagram online to wire up the 3-stage vtec.

and its OBD1

Valve covers are interchangeable. I guess the only way you're going to find out for sure is if you install it and dyno.

[dougshatch]

Yeah thats true turtle i was thinkin about to get em dyno but i dont know where i can find for DYNO

I'm lost for words. I really have no clue what that engine is. It seems to realy be vtec-e though; look at the size of the intake manifold and the addition of the EGR. Let me do some more searching around on Honda's japanese web site, and I'll post back if I find anything for ya. Here's a link to their Civic section if you want to look around it yourself (just use an online translator): http://www.honda.co.jp/HOT/ModelData/civic/index.html

Edit: Well here it is: http://babelfish.altavista.com/babel...%2feti_sy.html
It's basically just the JDM version of the USDM VX engine (D15Z1). And it has 92hp. It really would have been nice if Honda had used different engine codes for their JDM engines, instead of just D15B.

That looks more like a 96-2000 Civic HX motor to me.

I should've known it was a true vtec-e by the size of the IM. Whoops. Sorry.

[dougshatch]

Yes it come from 96-00 Hx

ummm..no it doesn't. If it did it wouldn't have a D15B engine code and it'd be OBD2. Are you sure it's an OBD1? Don't go by what the seller told you, go by the date on the head and the connector(s) on the distributor. 2 connectors for the distributor = OBD1, 1 connector = OBD2 (A or B, depending on how it's pinned).

[dougshatch]

that wat my friend told me he sed its Obd1 and from 96-00 and i know OBD2 come from 96-00...he sed no its OBD1 Here the Valve pics hope it would give you a hint http://i20.photobucket.com/albums/b2...uck_/valve.jpg

You're friend doesn't know what he's talking about. It's a jdm engine because it is stamped d15b. I don't know if they badged civics in Japan HX or not but either way. Listen to CivicSpoon. Look at the dizzy connector pin and the head date stamp to see obd.

BTW, if you have the car and the engine, do the swap, wire up the 3 or 4 extra wires for obd1 vtec, get a better IM. If the 3 stage vtec-e won't work that way, swap heads with a z6. I'm sure you can get it to work with various parts thrown together but I wouldn't run anything obd2 because you're just asking for headaches.
