ok i swaped my y7 head and intake mani for a y8 head and intake mani and put in a crower stage 1 cam. When you are stoped at a light or whatever and the car is runing it makes a noise like something is backfiring in the headers or somewhere in the exhaust. Any ideas? Also after the swap the car doesnt accerate from a standstill good, it like bogs down for the first few seconds.


Also should I have goten a new cam gear cause I put in the new camshaft? WOuld that cause any of this

 

now im not very familiar with d series motors but doesnt a mini me swap offset the timing? you also installed a new cam...did you get the car tuned after? if not that is what you NEED to do...or else the car just wont run right
edit*what ecu are you running?
that noise your hearing could also be detonation...dont beat on it till you get tuned

 

Sounds like timing to me. Tuning is a good idea as well, but timing will probably get you closer to drivable.

 

im running p28 ecu from the y7 cuz i got the wrong p2p ecu for vtec. Should I have goten a new cam gear with the new camshaft

 

i just blew up my 1.6 vtech motor in a 1994 civic. can and is it possible to install a 92 ls motor in to my car??? they are both automatics does that matter??? complete swap

 

I reccamend you get an adjustable cam gear

also make sure your timing belt is not off a tooth

and also make sure the ignition timing is dead on ( check with a timing light)
