Will a CRX HF mfpi setup on a d16a6 w/ pm6 ecu run well?
Ok I got the hoses all figured out.
Now I just want to know if the CRX hf manifold/injector/throttle body setup will run properly with my d16a6 engine and a PM6 ecu. I want to know if its going to run lean (the HF injectors are smaller than SI right?) or if I am going to have any problems related to this combination. I would also like to know if there would be any performance gain to be had from using an SI setup.

You'd get some horses out of moving to the PM6 manifold.

I am running Si intake on my D15a7 and I feel some extra power but not that major like 20 40 hp

What's a D15A7?
Anyway, if you use the HF intake manifold on a D16A6, the motor will certainly run. And it will get you around. But as others have said, the manifold and throttle body themselves are EXTREMELY small - WAY too small to make optimal power on a D16A6. I personally would just goto a junkyard and ge the right parts, since I absolutely HATE scraping gaskets from aluminum surfaces. But if you need something NOW, then the HF manifold will work in a pinch.

You need to just stop posting and do a LOT of reading before giving out any more hair-brained info.
And you do it a lot.
