Sorry I've been flooding this forum with my problems with the z6 I just swapped in my 88 dx crx. Now that I have the TPS fixed and the computer is throwing no codes at all, I still have some serious lack in power. This is a 125 horse vtec motor that cant get me up a very small incline at 60 in 4th gear in a 2000lb car? And I'm talking very small incline, not a mountain. What gives!? This is worse then when I had the stock d15 in it! I put new plugs, cap and rotor, plug wires, and air filter when I did the swap. I also replaced the fuel filter about a year back. Anyone have any ideas as what to check out?

 

no suggestions?

 

What cam gear are you using, did you correct the timing for the Mini-me?

 

Maybe a restricted exhaust, maybe a clogged catilitic converter.

Is it running rough?
You could check the compression.

 

I used the cam gear that came with the engine. Its the ZC D16Z6. All I did was take the old belt off and put the new one on the exact same way. I am using the exhaust that was on my car before and it does have a leak where the down pipe meets the cat, I couldn't for the life of me get it to line up right so at the higher rpms you can hear the leak. I would check the compression but I don't have a compression tester. Maybe I'll just do a custom exhaust, I was going to anyway since I am boosting it over the summer. Does anyone know of a d series 4-2-1 header with a 2.5" collector?

 

My ebay header came with a 2.5" collector.
