d16y5 swap to a 92 vx...?! can it work easily?
okay.. im not that new to the d-seiries world but i have some questions... i just bought a 92 vx vtec-e. its gutless. everyone knows that. ive seen a few boosted (d15z1's) and still getting 30mpg but its still just a little under the hp im looking for.
to start out lets talk about my goals in this project. i DO NOT want to do a z6 or y8 swap. if i did i would use the 30k mile usdm y8 i have in my garage. i want to stay in the vtec-e realm... i like the gas milage and they do have potential! read this post. https://honda-tech.com/zerothread?id=753403 i just want a little more hp. i will probably even keep the long geared tranny for the mpg until i can custom gear one. (ex 1-3rd dx 4th and hx 5th or something like that)
i hear tell of 370+hp boosted d16y5 motors and dont believe for a second that a vtec-e is crap or junk. so please do not give me the "vtec-e is crap" story.
next... a d16y5 is 115hp at the flywheel stock which is a 23hp improvement over the 92hp d15z1 (23 more hp sounds really nice) and still good gas milage. hx motors are aboundant and cheap because so many people dont think they are any good for hp. i see them all the time for $400. and later if i want to make a toy out of it i can boost it.
so i guess i need some swap info. what is the easiest and/or best way to go about doing this? the vx intake manifold sucks. hx manny is nice. but what would that mean i have to do as far as ecu choice and there will be a problem also with the different o2 sensors since one has a 5 wire and the other a 4 or 6 i cant remember.
input? suggestions? help!
thank you to anyone who seriously posts good info.

first of all. dx have the same 1-5 ratios as hx, only the dx uses 4.058 final drive instead of the hx's 3.72222
so a hybrid of the two is going to be a waste of time. However, dx gears with a vx final drive of 3.25 might be less painful (as opposed to the vx gear set with vx final drive) 140mph 3rd? no thanks.
vx intake manifold sucks (no pun intended) so use the hx intake manifold. it has larger runners than the vx while still maintaining that lovely egr valve
the hx and the vx use 5wire o2 sensors.
your easiest solution will be to use the vx ecu with the d16y5 motor. However, good luck tuning the p07 ecu (vx) because nobody messes with these ecu's do to the added lean burn function (and addition of the corresponding chip in the ecu that controls this)
after i have started my thread, I see less and less "vtec-e sucks" posts/threads. So no worries there. The vx is more optimized for overall fuel efficiency, where as the hx is designed for good fuel efficiency and good power. Basically, if you want to make power and still get mpg, then stick to the y5. But if you want crazy mpg and don't care about power (drive like a *****) then use a d15z1.
Again, there are more technical advanced arguments that cold be made, such as piecing together a hybrid of the two or some crazy ****. But again, I am trying to keep this simple without going too in depth.

Re: d16y5 swap to a 92 vx...?! can it work easily? (Bense)
thank you for the info! im am better able to formulate my new questions. this is the first 92+ civic i have owned. i have had 3 1991 hb's. so all my (limited) knowlege is with obd0.
1. engine harness: okay. lets say i bolt up the d16y5 block/head and complete intake. what are the complications with the wiring (im guessing the obd2 intake will be the biggest challenge)? do all/any of the block/head sensors match up from obd1 to 2?
2. the rest: the tranny should bolt up fine. and the motor mounts? what about the dizzy (i know there is a little complication with an obd0 dizzy when used on 96+ motors. [i researched a y8 swap for my 91 si.] but what about the 92-95 dizzy)?
3. exhaust: now i know this is a little nit picky. but on the vx and hx ehaust manifolds the o2 sensors are where all four cylinders exhaust converge. most headers have the o2 sensor in only one cylinders exhaust path. will this create a problem for the ecu?
there are probably many more things i am overlooking as well. if you can foresee any other complications please post
thank you all again! especially Bense!!!!!for your input.

you'll need to rewire the obd2 dizzy to obd1. It's not as complicated as you'd think just search on here. the d15z1 and the d16z6 are the only d-series engines that use that weird *** dizzy bolt pattern. So you can either get a d15b7 dizzy or rewire the d16y5 dizzy.
use your 92-95 mounts, tranny will bolt up fine, use whatever tranny you want. Don't worry about the ehxaust manifolds, just use the hx, or vx, whatever, it doesn't matter because they both have the catalytic convertor (sorry, crappy spelling cause i'm drunk) near the cylinder head.
there's a few things that are a little bit tricky, like the IAT sensor, you have to mount that on the intake tube instead of the intake manifold.
c3474i, I got your email and figured that I'd just respond here, so that others may use this as a guideline for the future.
