Explain requested
Props for your projects bro, excellent in everywhere... even the family wagon is awesome sleeper and a plus plus for solo testings.
Back to the question...
Honestly dont ask me, I did the swap by the book like the other guy explained and even knows I asked him questions. I dont question he did the swap, what I question the gains he states. First, our cylinder heads work with hydraulic lifters, not like Sentras or Hondas which REALLY get the benefits of performance cams.
I performed the swap and a friend asked me alleged stupid question of; What was your compression? I was skeptical, but could not resist not able to answer it. TO my surprise the compression did went down by 40psi. I tried different degrees to see if maybe I was a little off on any teeth or something. Checked the crankshaft was alligned, my timing, all good. Went back and check ALL cylinders and the compression was still the same 180 (remember I got Miata 2001 with shave head) from 230psi of what I usually have.
I even got scared because I drove the car like that for a while and said to myself the engine was losing compression from before or I bent some valves; just something to give some light to my results. So, immediately I took the ExIntake cam and installed the factory Intake cam, did the test and compression was a healthy 230.
Double check torque for the cams, any little thing. I honestly dont have any other answer than to say, you do the swap and see that what I say is not BS. The car ran fine and had no bad idling. This is what I am going to do. In the next few days do the swap again and take pics and if possible a video.
Anyway, just do the swap and see the results.
