large d15z1/ vx parts collection

[vrmouseyd15b]

thank you, the pleasure was all mine. see what else you've got laying around for my d15b if you're looking to make room, make me a pile. I'll think about picking it up or shipping when we know how much you've got. I had no idea what you were up to in PA with the "lean burn and prosper" until I started reading back.WOW.

much respect. you've totally got more skills than most dudes out there, and it shows clean as day in your threads. It'd be a pleasure to get back out there and see what other goodies you might be hiding.

I got ahead of myself again last night and pulled the whole tranny apart and bearings pulled before i could think to take any pictures!! oh well.we'll see what happens with this motor
I'm thinking remote turbo lean burning 1.5 liters of fury with my current LX tranny with lsd and building an Integra or something for the boss ( the vx tranny will go into the MINION )
she actually loves the idea. The catch is she wants it shiny red. done.

Thanks again, Victor.

How did the tranny look inside? I wouldn't be suprised if the motor still had the original clutch on it

[vrmouseyd15b]

I sent you pics directly. Can't get them to show up on here. Not sure why.

I was talking with my buddy here about you not making enough power? My first choices would have to be cat back exhaust and then the external spark mod at the dizzy so you can run a blaster series coil and get some fatty plug wires (mine are 10.2mm) and go for a hotter plug.

or you could try and get the dual vtec head and ecu. The best of both worlds. Lean burn ran up to about 3250 rpm on the ride home then those Damn Hills would have the ecu pop into 1st stage vtec people were giving me looks when they got on the side of me and then wooooohhh!

Second stage is where it's at though. a few times I really got on it. I have a thing for tunnels, I made a lot or noise on the way home that was like a mile. Loved it. (I think that's the Shizzle loves it past 5k rpm crazy loud and b series type vtec kick you heard me? )

to me, it's worth the couple mpgs for the holy crap factor :-)

[slownugly]

Oh man that sounds like so much work haha

[vrmouseyd15b]

I've been playing with this setup for about six months now, and as soon as my bearings and seals kit and lsd block come in, she's coming back apart again!

I'm still learning about the car stuff - Jarrod is my go to guy for projects I'm still scared of, but this tranny will be all me! Of course I'll ask for help to throw it in. If you've seen the clutch in my Picasa, that's him putting it on.

It's a good time, and so far I've only had a few big setbacks (that damn 3 wire iac was a big one for me) like finding the right ecu for my setup. I bought one on eBay chipped and had it Street tuned, but nothing made this car go like the current 37820 p2j-j62 (jdm cvt 3 stage vtec)!

I'm just Damn stubborn. Once I learned what I had, I had to make it sing!

And in the chase for the best of both worlds of performance and mpgs, I found myself in PA.

YOU CAN DO IT!

hell, now I want to turbo the other motor and build the Old lady something!

I'm in the process of putting a JDM D15B shortblock in my '90 HF at the moment...
It was the only motor I could get locally that was rebuilt and ready to go,it cost $250 and was freshly rebuilt,I'm putting my B6 head and intake on it it's going to be interesting to see what the MPG will be...personal best was ~53mpg with the B6...

But in the long haul I'd love to have the 3 Stage V-TEC,but with me being on OBD-0 I know that'd be a heck of a swap though right or am I missing something?Totally jelly of a working 3 Stage,regardlesss...congrats man!
I wish I could find more info on the swap,I'm going to end up getting lean-burn in this HF eventually but trying to figure out what'd be the best way to take considering I can't run a Z1 head because of the high CR..

[vrmouseyd15b]

I got my ecu on eBay for 29 bucks from JDM parts something or other. the head is the hard part. I've seen about guys converting their head to dual Vtec somewhere online and drilling their head for the second vtec oil passage. you are the only person I know that I think could pull it off.

[mbolton1990]

lol Dont be so gracious.



Heres the head

96 00 Honda Civic EX 1 5L SOHC Dual 3 Stage V Tec OBD2 Head JDM D15B w Solenoid | eBay

Sorry to derail thread,in the name of leanburn I apologize.




EDIT;
I'm getting a hunch that since normal V-TEC can be manually engaged with +12V at the solenoid beyond the set RPM (5200 etc)and with the right oil pressure that VTEC-E should be able to be engaged the same way on that head.I'm thinking of a in-car switch that would kick off the VTEC-E solenoid and then wire that switch to manually change the AFR to 20:1 via a modified/flashed ECU.The benefit of this is that I would still be able to be on OBD-0 in my HF and would just have to re-wire a few sensors/dizzy and it *in theory* would work...

Hmm more research must be done.

EDIT EDIT;
ahh
So here's the ECU you got?

That is the head exactly. And the ecu.

Look up vrmousey on YouTube for a general "lean burn explanation" of this ecu (37820 p2j-j62)

the trick with this setup is that it's a cvt ecu, and you run a manual tranny. This model ecu is supposed to have a separate traction control module, but it doesn't really need it except for the power/econo/whatever switch. It has outputs for both stages of vtec and supports lean burn (I've run it up to about 3300 rpm's in lean burn). It has a lean burn indicator light (switched ground from a30 I believe)
and I explain the vtec pins in the video:
Lean burn - YouTube

this is a quick walk around. I've moved the iac into the cab now. That's the other trick. I'm running a 3 wire iac remotely. That keeps the check engine light away. Check engine light means no lean burn. No lean burn on a cold motor either.

For the ecomodders! - YouTube

I just adjusted my idle to about 900 rpm's no load, Tps adjusted to .5 volt, 4.5 volt wot, and slightly retarded timing.

EDIT: Ijust broke 43mpg's with my 4 door lx and lx manual tranny! Tranny case is all blasted naked now, pinion separated. that case goes to work with jarrod tomorrow for powdercoat and i'm stuck waiting for parts for lsd and bearing kit

[mbolton1990]

Good stuff man,thanks for shedding some light on the D15B 3 Stage mystery.
Very interesting about the ECU,I know the P2J-003 are uber expensive and really rare thats amazing you got it working with the $30 one,haha kudos!With a factory OBD-2 car you were already a few steps ahead of the game,I'm considering snagging a engine harness out of a OBD-2 Civic at the local PNP and seeing how different it is from the OBD-0 one I have,and possibly using it with that head when the time omes.
43MPG in with a LX trans is impressive!You really should get the HX/CX or even a HF trans if possible I loooooove my HF trans,I can go 60MPH @ 1700 RPM's iirc.Wow with you in lean burn I wouldn't be suprised if that pushed you over 60MPG..

Trans swaps are a joke in these cars,I could probably do one in 3 hours give or take.
BTW I've got the swap almost done,wiring is sorted,head's torqued down putting the rad in,filling with fluids(going with GM Synchromesh FM this time around for the trans),gotta sort all the small bits out and I'm hoping for a test crank later tonight.

Fingers crossed,
I'm going to check out those videos later tonight for sure!

EDIT:I heard somewhere that the 3 Stage head runs in 12V mode 'natively' (without any of the solenoids engaged at all) it then crosses over to standard 16V mode after ~3XXX RPM's ,is this true?
If so it'd mean it would 'stay in leanburn' virtually all the time,like in regular city driving,etc which I find kind of hard to believe.It's hard getting straight answers sometimes on such a subject...
