Hey man Welcome to HONDASWAP ! Generally id say to start off with a build thread of your car with pictures of it and the engine and things done to it etc. but ok you are having a problem and slow down there cowboy sounds like a big collaboration of stuff going on there did you just have a bunch of misc stuff laying around and go fack it ? lol anyways your problem long as assembled correctly probably isnt the engine , could be anything from a bad dist to a still a bad ground or in wiring or a fuse even the car would have to be looked at in all honesty , and btw with the collaboration of stuff you put together if read correctly its pretty much still a z6, the block and head castings are the same
