Hello, ive been reading this page for a long time and got great answers but never needed to register until today when i really got fed up with my car.
so... I had a fully built d15b (jdm vtec one) that i blew up. Just did an engine swap and put in a stock d16z6 with a z6 head and skunk2 cam. I hooked everything up just like the way it was with a d15 block and im having some problems that i cannot figure out. The car runs for only 1 minute when cold then keeps dying. The only way to keep it running is to hold the gas down, When i slightly hold the gas the rpms bounce like crazy around 1500. Does the same thing when i drive it (stutters at 1500rpm unless i change to a lower gear and raise them up) Seems like there is a power loss. 2 seconds after i start it the check engine light comes and stays on. The lightshow autometer stays on green. Sounds maybe its misfiring sometimes.

I checked the timing maybe 20 times yesterday, I even put the stock camgear on to make sure its dead on (thought maybe skunk2 was off), I reconected all the sensors. Any ideas would be great. thank you.

^ Why? i have a turbo cam in it, why do you think thats the problem?

Why do you have a turbo cam in a stock engine? Is the ECU tuned for it?

Bluegixxer1k

Yes, its got a turbo xs kit with s200 on a p28

Would be nice to mention this up front. Sounds like a crappy tune then. Did you retune the Hondata?

Bluegixxer1k

No i did not retune the hondata, Im scared to drive it at this point. The car was just running with the exact same setup except for a d15b block and head. I replaced the cam from the d15b head to the d16z head. so bassically everything is the same exept the actual block and head. The car was running 3 days ago with 0 problems on that setup but i screwed up and overboosted it. Now i had to move it out of the garage because they are repaving it so i had to do the swap quick. Im 100% sure that i hooked everything up the same! I just dont understand what couldve went wrong. Does a d16z6 need something done different than a d15

Bluegixxer1k

Oh also i changed the timing belt so its not that. i know the d15 got 1 tooth less.

If it was the same you wouldn't be having an issue I think.

civic-steve-94

you swapped in a cam to the z6 did you do a valve adjustment after doing so

vartok

well, i would bet it needs a retune. your maps for for a 1.5l and you upgraded to a 1.6l... just my .02 though

dont worry about the .1l difference, he used a 1.5 block. you did a mini me swap, your compression is up. sounds like a timing/tune issue to me.

dylan4132

check ignition components.. distrubutor cap and rotor button, spark plugs and wires i had a similar problem with mine and the tune up had it running like new again

Bluegixxer1k

I never did a mini me, the old block was a jdm d15b vtec and the new one is d16z, i think i lowered the compression.

Bluegixxer1k

Im going to recheck everything for 1000th time today, if everything seemes good the car is going to one6 for a tune.
Also yes, i had a shop swich the cam and do a valve job because i never did that myself before.
