sorry about the horn honk lol... its hard to hold a damn phone and drive on a bad road
h22, i just did a head swap and delta regrinds(i just called them, and they said they put the old stage 2 skunk 2 profile on the cams, which is VERY close to the tuner stage 1 now), i used all old sensors and they all worked fine

2nd link is idle and exhaust sound, when cold

CB7's don't come with a VTEC motor.

Unless you did a swap. And if you did, we have no idea what motor you have.

Just a head swap?
So you didn't replace/add in any wiring, Or replace the ECU?

i soldered the vtec wires together cause they were only butt connected. other than that, nothing.

bump, i could use some help

You are dodging both of their questions is it a full H22 or a F22 with a H22 head?

And yup it matters.

It's a H22 head swap onto a H22 block, you and I were just discussing his idle in his other thread, H22 head swap something or other.

[93redcb7]

yes its a h22 head on h22 block, franken motors arent work the work... but did u guys even bother to watch the video's?

[SOHC-FTW]

Yes and i can tell you your timing's still wrong and your valves are out of adjustment use close to stock valve specs not delta's.

Edit: What ecu are you running? stock p13 or some generic chipped p06/p28/p72 etc?

[evil_demon_01]

other than that, nothing.

So your still running the F22 ECU - Thats your first problem.

i have a p28 chipped, and ill check into my timing when i can get the chance, my valve lash is already done

[SOHC-FTW]

The chipped ecu might very well be your issue, if you have access to a p13 i'd run that. And if you haven't adjusted your valves since that video they need redone because they were ticking quite loud.

fixed


Yes they are, but only if your making something useful out of spare parts and have already done engine builds. OR you know someone with junk that you can make usefull which would cost you virtually nothing to aquire. A motor being worthwhile depends on ones capabilities and access to equipment.

Did you check voltage for the ECU's pinouts when it should be turning the solenoid on? Thats where I would start, it would be pretty simple to tap into the wire and use a volt meter while driving.

i had the car running fine before i did a head swap... vtec worked and everything, on the same ecu. nothing was wrong with the car besides it burnt oil and the cams had some wear marks on them, and thats why i did a head swap, so i wouldnt have down time(rather than the weekend it took). I used all the same sensor's and everything. vtec is click but it like bogs and feels/sounds like its just going to die

So then you had already swapped an engine in, and established it worked 100%. Then you did a head swap, and now it sounds terrible, and VTEC rpm doesn't seem to pull hard at all?


Compression check the engine, leakdown test as well if you have the ability. Double check the dizzy, and make sure the engines timing marks all line up.

Are you sure the "new" head you put on your old block was level and true? I presume you used a new headgasket. You could have a bad head.

Its usually a good idea to mill/deck engine parts that are used which came from different origins. No 2 blocks and heads settle the same.

BTW. H22's usually burn oil via the rings, not the head. The FRM sleeves eat up piston rings.
