After driving sr20det and ca18det you may be just a little dissapointed in the performance. Or mabey it just won't come to life. What is the compression like? What carb are you running? Was it off the 1K or tha A14? How many Km's were on the engine before you started? Did you replace the timing chain also? Was the cam dialed in? How many KV is the coil producing at idle through to desired rpm? What leads are you running? What are the points like? Condensor?

Don't assume just because a part is new that it is working o.k. I have replaced many parts over the years, expecially electrical, that were no good from the box.

Too many variables for a motor like this. Sometimes things just go bad. I remember that it was pretty weak on the dyno day, even by A14 standards. There has to be an underlying problem with it and throwing performance parts at it won't fix it. Unless you accidentally replace the failed part.
