Intake manifold and camshaft...

[91f22a]

I'm sure this is a stupid noob question, but I did a quick search and came up empty. I don't know anything about the f series. I might be picking up a 91 accord lx 5-speed. What honda manifolds and cams can be swapped into that motor. I'm assuming it has an f22a1? I know on d series you can swap cams and manifolds around to make a little more power. Even if someone has a link to a thread I missed I'd appreciate it.

This is just what I've heard lately, but the F22a6 manifold and/or H23 manifold work better than the F22a1. As for the cam you can get an F22a6 cam which is only slightly better or get a 272 cam regrind which is what most recomend for stock valvetrain.

Ok. Thats exactly the info I was looking for. I know on my old civic with a d15b7 I used a d16z6 vtec intake mani and a d16a6 non vtec si cam and picked up quite a bit.

get the H23 mani.!..thats what im doing

[91f22a]

I think I will. If i get the car I'll get an h23 mani. Thanks.

Most common swap as mentioned is the H23 manifold. Another upgrade is throwing the H throttle body on there. Cams you have options you can purchase a delta regrind or order a cam from bisi. Both are good choices depending on your power goals and such.

I am also a noob here... what do you mean by a delta regrind cam or a bisi cam? are they companies or something??

[91f22a]

Bisi is bisimoto engineering. He has the fastest unibody n/a civic in the world or something like that. Delta 272 is a reground cam. Thats where they take an old cam and add metal to the lobes and regrind it to different specs. Both are great options. We use delta regrinds alot in d series hondas. Bisi is awesome. It just depends on how much you wanna spend.

Actually, a main difference is that our cams are specifically designed for the engine application, using our in-house dyno. Unlike other companies, we do not use the "one size fits all" philosophy in cam grinding. I guess that is why we have all the sohc records..lol.
