What's the news?

djslim23

Thx for the tips guys. Somehow I did not receive any emails regarding activity in this thread until today :? So what kind of solenoid would I need for the EGR? My intake manifold came with an EGR without a vacuum nipple. I would much rather get the solenoid I need than hack up my wiring more to get the other EGR to work . So I just need pointed to what I can use...Thanks!!!

Basically same as before. It doesn't surge at all, I have no CEL, but it is very boggy at low rpms and not very smooth. It definitely seems to be a problem with the EGR, which hopefully an answer to my question above can solve!!!

djslim23

bump!

djslim23

bump it up--to the top--someone help--me with this swap

I think a vacuum T and an extra vacuum hose is cheap enough to just get and give it a try this way (even though you were told not to).
Just to see what it changes. At least I would do it.
I don't think in the older cars EGR's were connected through a solenoid.

nikitad

And oh! Just curious - which distributor are you using? Y5 or D15B?
I demember Y5 distros being a bit different shape-wise (not sure if they affect timing any differerntly than Y8)

nikitad

O, and to contradict the poster above,
according to what I see on this pic,
evap, is the one that is not connected to the vacuum directly:

I am using the y7 dizzy, and I have been told they are the same. It bolted up without issues. Also, it is currently hooked up with a T. I would assume the dizzy could be the problem but the engine ran much better with the d15b intake mani that came off it, but of course I didn't have IACV function which sucked *****, and the egr wasn't even hooked up then...

Jimster480

Yes the Y7 dizzy is the same as the Y8 one. The IACV isnt really needed if you can bypass it lol I dont have one in my car. And idk what your going to do about the EGR though. Its weird that they have EGR's over there in Japan on OBD1. Unless the 3 stage VTEC model came out of a gas mileage version (idk which car it comes out of).

djslim23

It's actually OBD2a, maybe that's why you're confused. And I cannot live with out the IACV, it's really hard on the transmission as well. The engine comes out of the 96-98 Civic Vti and the 99-00 Civic Vi-RS. It is vtec-e + the wildest vtec cam of all the d-series. Supposed to get around 40mpg.

Jimster480

Well it why does it have a egr? And u can prop the throttle to fix rhe iacv issue. But Idk how it would be hard on the tranny.

djslim23

I believe it is for Japanese emission purposes...not 100% sure though. I'm not quite sure what you mean about propping the throttle to fix the iacv issue (sorry I'm not a very handy mechanic). When I ran without the IACV for a month it ate my tranny to bits. It literally went from minor chattering to full blown 'can hear it over the mugen exhaust' chattering. The reason was that when I was driving and went from 0 throttle to >0 throttle, the car would lurch forward. Pita.

Jimster480

Do you ahve an auto? Because i mean with a manual i dont see how engine speed would affect the tranny. Especially not a lower engine speed. And you prop the throttle cable to hold onto the arm on the throttle body so that it stays open a bit all the itme. This is how it is on my car as I have no IACV at all.

djslim23

No, 5spd. Ok, that's what I thought you meant. I know it was hurting the trans because without the IACV, I could literally hear the tranny stressing as the car would lurch. No matter how I drove, it couldn't be fixed. Also, I'd rather run with my IACV and throw no codes like the computer wants and keep my throttle where it should be. I trust that it doesn't cause problems because you seem very educated, but I'd rather get it running exactly how it should.

IACV had nothing to do with your tranny blowing. Obviously you want it run right, but it had absolutely nothing to do with the tranny.

djslim23

My tranny hasn't blown. But the lack of IACV would make it sound as if I was engaging and disengaging the clutch while driving. Maybe there was a separate issue with my tranny after the swap that resulted from a bad transplant. I would not know for sure because I had several people helping me with it. Anyways, that is not my issue now, my issue is with the engine bogging and running poorly. My only known option now to attack is the EGR. If that doesn't fix it, I'll be looking for more solutions.

EDIT: Figured out it is the clutch/flywheel that I'm having issues with

Hey djslim23: Awesome thread thanks. I'm at the latter stages of an almost identical swap. I've hit ecu issues in that I'm struggling to find an ecu for my 5 speed manual 2000 Civic with 3 stage vtec D15B.
I noticed on another thread of yours you asked for help locating an ecu. You replied to yourself "tip top". There's no clue as to where you got yours.

From you or anyone else out there, any idea where I can get a P2J J11 from?

Any updates on the boggy performance? I noticed on a bunch of other forums and posts about how important it is for idling to make sure the inlet manifold gasket was new and soundly fitted. From my swap, the gasket appears infallible yet it features as a potential problem for idling. Just my thoughts cos I'm far from any form of expert.

I have a whole host of other problems with my engine running unbelievably rich but won't raid this thread with my issues.

Keep up the superb work man.
KMF.

Hey man, glad it could help!! I actually ended up getting mine from HMO, where I got the engine from. Last summer when I got it, they had a wait list for them, and people who bought motors from them got first dibs. Their price is $200+shipping, but they gave it to me for $150 since I got the motor from them.

And yup, I still have some bogging issues, but I'm pretty sure it's simply a vacuum leak. I didn't replace the intake mani gasket and I know it didn't look good (I was being impatient). But I don't have any idling issues, just the bog. Good luck, and feel free to PM me!

iam working on my swap now, but one of the plug been cut off leaving 2 wires hanging.





could you help me to indentify what plug it belongs to?
thanks.

Jimster480

yea it looks like the wires for the IAT plug

JDM_addict

my IAT plug still attached.any other guess?

djslim23

I can take a look when I get home later today

Jimster480

Well there aren't that many 2 wire sensors. The 2 Wire Sensors are IAT, ECT, IACV (Depends), VTEC Oil Pressure, EVAP, Purge, CKP, CFS (Cooling Fan Switch). Ones that are on a plug with 3 wires? IACV, IAT, CFS?

JDM_addict

Thanks bro,


i got all the plugs mentioned by u.
