Been working on the F22A6 and some pics to share!

Hey people, I was wrong about the D15B7 distributor.

It will work, but the TDC sensor is 180 degrees out. And also TDC sensor is clocked a few degrees out from the F22 TDC sensor. So the distributor needs to be basically maxed out to full adjustment to get 16 degrees.

So I swapped in a F22 distributor and did the internal coil mod (one solder, one cut wire, and one borrowed wire from another distributor.).

Runs like a champ. Seems to be getting quicker as the days go by, and its seating in. Needs more exhaust for sure.

Crazy build!!! Great info on the intake mani, cant wait to see this thing running

Awesome build, bro. Been watching it on dseries. How do you feel about using the RAA intake on an F22A? Been comtimplating picking one up from eBay as they're going for about $85 and really designed for low to midrange torque

From what I can tell, he's using a PRB(02-06 RSX-S) intake manifold. I'd guess from the extra length and shape of the runners on the RAA intake, it won't clear the rear subframe on most Hondas.

I know what he is using and what chassis it's going into. Our accords have lots of room though

[Chrisnick]

Only one way to find out! From looking at most stock can dynos, it seems the stock intake/cam combo dies at about 5k pretty hard. It could help, but I think its more of a cam issue than intake manifold. Without knowing if the intake is pulling vacuum past that rpm kind of leaves us in the dark though.

you just blew my mind with the intake... do coolant lines mtch up or are you plugging those? i would never do this for boost but for na and particularly h2b its great.

I think its worth a try. But I dont know if it would be a benefit over the OEM F22 intake manifold with its butterfly valves, etc.

Most everything works perfectly. I had to do a few little modifications.

I relocated the t-stat housing, so it sits by the tranny. I did this by cutting the OEM water pipe on the F22, and just using a chopped rad hose and worm clamp to extend it from the back of the block.



Then you also see I had to add a secondary water path so warmed coolant can rush over the t-stat and actually make it open from heat. That is the small 5/8ths hose, which I just routed back into the cylinder head on the side port under the distributor. And I blocked off the water port on the back of the head with a 1/2" NPT plug.

Nice ingenuity there. We're gonna a need ripper vids soon

O Lordy .. I've been following this thread! We have some talented and very creative people here.
Congratulations so far .. I am very impressed!

Keep up the diligent work, and PLEASE keep the images coming.
Now, I want to watch what you do to "fine-tune" this gem of a motor, then I'm diving in lol!

Great descriptions to go with some awesome pictures ...

Wow awesome work man! I love seeing people try new things and make them work! I can't wait to get home so I can dive into mine! Keep the good stuff coming.

sweet build!!! cant wait to see some video of this.
